标签:function me word ueditor 编辑器 HTML var 上传 粘贴

 当前功能基于PHP,其它语言流程大致相同

 

1.新增上传word json配置

在ueditor\php\config.json中新增如下配置:

 

    /* 上传word配置 */

    "wordActionName": "wordupload", /* 执行上传视频的action名称 */

    "wordFieldName": "upfile", /* 提交的视频表单名称 */

    "wordPathFormat": "/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}", /* 上传保存路径,可以自定义保存路径和文件名格式 */

    "wordMaxSize": 102400000, /* 上传大小限制,单位B,默认100MB */

    "wordAllowFiles": [".docx"] /* 仅支持docx格式的word */

2.修改编辑器配置文件,在工具栏上新增按钮

在ueditor\ueditor.config.js文件中,新增按钮名称"wordupload",并添加鼠标悬浮提示,如下所示:

 

        //工具栏上的所有的功能按钮和下拉框,可以在new编辑器的实例时选择自己需要的重新定义

        , toolbars: [[

            'fullscreen', 'source', '|', 'undo', 'redo', '|',

            'bold', 'italic', 'underline', 'fontborder', 'strikethrough', 'superscript', 'subscript', 'removeformat', 'formatmatch', 'autotypeset', 'blockquote', 'pasteplain', '|', 'forecolor', 'backcolor', 'insertorderedlist', 'insertunorderedlist', 'selectall', 'cleardoc', '|',

            'rowspacingtop', 'rowspacingbottom', 'lineheight', '|',

            'customstyle', 'paragraph', 'fontfamily', 'fontsize', '|',

            'directionalityltr', 'directionalityrtl', 'indent', '|',

            'justifyleft', 'justifycenter', 'justifyright', 'justifyjustify', '|', 'touppercase', 'tolowercase', '|',

            'link', 'unlink', 'anchor', '|', 'imagenone', 'imageleft', 'imageright', 'imagecenter', '|',

            'simpleupload', 'insertimage', 'emotion', 'scrawl', 'insertvideo', 'music', 'attachment', 'map', 'gmap', 'insertframe', 'insertcode', 'webapp', 'pagebreak', 'template', 'background', '|',

            'horizontal', 'date', 'time', 'spechars', 'snapscreen', 'wordimage', '|',

            'inserttable', 'deletetable', 'insertparagraphbeforetable', 'insertrow', 'deleterow', 'insertcol', 'deletecol', 'mergecells', 'mergeright', 'mergedown', 'splittocells', 'splittorows', 'splittocols', 'charts', '|',

            'print', 'preview', 'searchreplace', 'drafts', 'help', 'wordupload'

        ]]

        //当鼠标放在工具栏上时显示的tooltip提示,留空支持自动多语言配置,否则以配置值为准

        ,labelMap:{

           'wordupload': '上传word文件',

        }

在ueditor\themes\default\images\目录下新增按钮图标"word_upload.png":

 

 在ueditor\themes\default\css\ueditor.css文件中新增按钮样式:

 

.edui-for-wordupload .edui-icon {

    width: 16px;

    height: 16px;

    background: url(../images/word_upload.png) no-repeat 2px 2px !important;

}

最后在ueditor\ueditor.all.js文件中editorui["simpleupload"] = function (editor){}后面添加如下代码:

 

/* word上传 */

    editorui["wordupload"] = function (editor) {

        var name = 'wordupload',

            ui = new editorui.Button({

                className:'edui-for-' + name,

                title:editor.options.labelMap[name] || editor.getLang("labelMap." + name) || '',

                onclick:function () {},

                theme:editor.options.theme,

                showText:false

            });

        editorui.buttons[name] = ui;

        editor.addListener('ready', function() {

            var b = ui.getDom('body'),

                iconSpan = b.children[0];

            editor.fireEvent('worduploadbtnready', iconSpan);

        });

        editor.addListener('selectionchange', function (type, causeByUi, uiReady) {

            var state = editor.queryCommandState(name);

            if (state == -1) {

                ui.setDisabled(true);

                ui.setChecked(false);

            } else {

                if (!uiReady) {

                    ui.setDisabled(false);

                    ui.setChecked(state);

                }

            }

        });

        return ui;

};

 

最终样式如下:

编辑

 3. 新增语言配置

在ueditor\lang\zh-cn\zh-cn.js文件中在"simpleupload"配置下方新增以下配置:

 

'simpleupload':{

        'exceedSizeError': '文件大小超出限制',

        'exceedTypeError': '文件格式不允许',

        'jsonEncodeError': '服务器返回格式错误',

        'loading':"正在上传...",

        'loadError':"上传错误",

        'errorLoadConfig': '后端配置项没有正常加载,上传插件不能正常使用!'

    },

    'wordupload':{

        'exceedSizeError': '文件大小超出限制',

        'exceedTypeError': '文件格式不允许',

        'jsonEncodeError': '服务器返回格式错误',

        'loading':"正在上传...",

        'loadError':"上传错误",

        'errorLoadConfig': '后端配置项没有正常加载,上传插件不能正常使用!'

    },

在ueditor\lang\zh-cn\en.js文件中在"simpleupload"配置下方新增以下配置:

 

'simpleupload':{

        'exceedSizeError': 'File Size Exceed',

        'exceedTypeError': 'File Type Not Allow',

        'jsonEncodeError': 'Server Return Format Error',

        'loading':"loading...",

        'loadError':"load error",

        'errorLoadConfig': 'Server config not loaded, upload can not work.',

    },

    'wordupload':{

        'exceedSizeError': 'File Size Exceed',

        'exceedTypeError': 'File Type Not Allow',

        'jsonEncodeError': 'Server Return Format Error',

        'loading':"loading...",

        'loadError':"load error",

        'errorLoadConfig': 'Server config not loaded, upload can not work.',

    },

4.修改过滤配置

由于导入word时,编辑器会自动过滤掉图片等样式,所以需取消过滤

在ueditor\ueditor.config.js文件中修改如下配置:

 

// xss 过滤是否开启,inserthtml等操作

,xssFilterRules: false

//input xss过滤

,inputXssFilter: false

//output xss过滤

,outputXssFilter: false

在ueditor\ueditor.all.js文件中,修改UE.plugins[‘defaultfilter’],新增return ;如下所示:

 

// plugins/defaultfilter.js

///import core

///plugin 编辑器默认的过滤转换机制

 

UE.plugins['defaultfilter'] = function () {

    return;

    var me = this;

    me.setOpt({

        'allowDivTransToP':true,

        'disabledTableInTable':true

    });

    ……

5.安装PHPword

composer require phpoffice/phpword

6.自定义文件转换类

实现上传文件,并将文件转换为HTML

直接将ueditor自带的上传文件"ueditor\php\Uploader.class.php"类内容直接复制到自定义WordToHtmlController.class.php文件中

 

<?php

 

class WordToHtmlController

{

    public function index()

    {

        require 'vendor/autoload.php';

 

        $base64 = "upload";

 

        $config = array(

            "pathFormat" => '/public/uploads/word/{yyyy}{mm}{dd}/{time}{rand:6}',

            "maxSize" => 102400000,

            "allowFiles" => [".docx"]

        );

        $fieldName = 'upfile';

 

        include 'Uploader.class.php';

        $up = new Uploader($fieldName, $config, $base64);

        $path = ltrim($up->getFileInfo()['url'], '/');

 

//        $phpWord = \PhpOffice\PhpWord\IOFactory::load('public/uploads/word/20211029/test.docx');

        $phpWord = \PhpOffice\PhpWord\IOFactory::load($path);

 

        // 直接输出到页面显示

//        $phpWord->save('php://output', 'HTML');

 

        $xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord, 'HTML');

 

        header("Content-Type:text/html; charset=utf-8");

        exit($this->replaceImageSrc($xmlWriter->getContent()));

//        exit($xmlWriter->getContent());

    }

 

    /**

     * 将HTML代码中的所有图片地址替换

     * @param $content string 要查找的内容

     * @return string

     */

    private function replaceImageSrc($content)

    {

        $preg = '/(\s+src\s?\=)\s?[\'|"]([^\'|"]*)/is'; // 匹配img标签的正则表达式

        preg_match_all($preg, $content, $allImg); // 匹配所有的img

 

        if (!$allImg)

            return $content;

 

        foreach ($allImg[0] as $k => $v) {

            $old = ltrim($v, '" src=');

 

            preg_match('/^(data:\s*image\/(\w+);base64,)/', $old, $temp);

            $tempType = $temp[2];   // 获取类型

 

            // 判断目录是否存在,不存在时创建

            $tempFilePath = 'public/uploads/word_images/' . date('Y-m-d', time());

            if (!file_exists($tempFilePath))

                mkdir($tempFilePath);

 

            // 拼接完整路径

            $tempFileName = $tempFilePath . '/word_image_' . time() . $k . '.' . $tempType;

            $base64 = str_replace($temp[1], '', $old);

 

            file_put_contents($tempFileName, base64_decode($base64));

 

            // 替换路径字符串

            $content = str_replace($old, $tempFileName, $content);

        }

        return $content;

    }

}

 

 

7.编辑器实现导入操作

在ueditor\ueditor.all.js文件中UE.plugin.register('simpleupload', function (){})下方新增如下方法

 

 

/**

 * @description

 * word上传:点击按钮,直接选择文件上传

 */

UE.plugin.register('wordupload', function (){

    var me = this,

        isLoaded = false,

        containerBtn;

 

    function initUploadBtn(){

        var w = containerBtn.offsetWidth || 20,

            h = containerBtn.offsetHeight || 20,

            btnIframe = document.createElement('iframe'),

            btnStyle = 'display:block;width:' + w + 'px;height:' + h + 'px;overflow:hidden;border:0;margin:0;padding:0;position:absolute;top:0;left:0;filter:alpha(opacity=0);-moz-opacity:0;-khtml-opacity: 0;opacity: 0;cursor:pointer;';

 

        domUtils.on(btnIframe, 'load', function(){

 

            var timestrap = (+new Date()).toString(36),

                wrapper,

                btnIframeDoc,

                btnIframeBody;

 

            btnIframeDoc = (btnIframe.contentDocument || btnIframe.contentWindow.document);

            btnIframeBody = btnIframeDoc.body;

            wrapper = btnIframeDoc.createElement('div');

 

            wrapper.innerHTML = '<form id="edui_form_' + timestrap + '" target="edui_iframe_' + timestrap + '" method="POST" enctype="multipart/form-data" action="' + me.getOpt('serverUrl') + '" ' +

                'style="' + btnStyle + '">' +

                '<input id="edui_input_' + timestrap + '" type="file" accept="application/msword" name="' + me.options.wordFieldName + '" ' +

                'style="' + btnStyle + '">' +

                '</form>' +

                '<iframe id="edui_iframe_' + timestrap + '" name="edui_iframe_' + timestrap + '" style="display:none;width:0;height:0;border:0;margin:0;padding:0;position:absolute;"></iframe>';

 

            wrapper.className = 'edui-' + me.options.theme;

            wrapper.id = me.ui.id + '_iframeupload';

            btnIframeBody.style.cssText = btnStyle;

            btnIframeBody.style.width = w + 'px';

            btnIframeBody.style.height = h + 'px';

            btnIframeBody.appendChild(wrapper);

 

            if (btnIframeBody.parentNode) {

                btnIframeBody.parentNode.style.width = w + 'px';

                btnIframeBody.parentNode.style.height = w + 'px';

            }

 

            var form = btnIframeDoc.getElementById('edui_form_' + timestrap);

            var input = btnIframeDoc.getElementById('edui_input_' + timestrap);

            var iframe = btnIframeDoc.getElementById('edui_iframe_' + timestrap);

 

            domUtils.on(input, 'change', function(){

                if(!input.value) return;

                var loadingId = 'loading_' + (+new Date()).toString(36);

                var allowFiles = me.getOpt('wordAllowFiles');

 

                me.focus();

                me.execCommand('inserthtml', '<img class="loadingclass" id="' + loadingId + '" src="' + me.options.themePath + me.options.theme +'/images/spacer.gif" title="' + (me.getLang('wordupload.loading') || '') + '" >');

 

                function callback(){

                    try{

                        // 获取到内容

                        var body = (iframe.contentDocument || iframe.contentWindow.document).body;

 

                        // 获取加载中图片并关闭

                        var loader = me.document.getElementById(loadingId);

                        loader.removeAttribute('id');

                        domUtils.removeClasses(loader, 'loadingclass');

 

                        // 向编辑器赋值

                        me.setContent(body.innerHTML, false);

                        // me.execCommand('insertHtml', body.innerHTML);

                    }catch(er){

                        showErrorLoader && showErrorLoader(me.getLang('wordupload.loadError'));

                    }

                    form.reset();

                    domUtils.un(iframe, 'load', callback);

                }

                function showErrorLoader(title){

                    if(loadingId) {

                        var loader = me.document.getElementById(loadingId);

                        loader && domUtils.remove(loader);

                        me.fireEvent('showmessage', {

                            'id': loadingId,

                            'content': title,

                            'type': 'error',

                            'timeout': 4000

                        });

                    }

                }

 

                /* 判断后端配置是否没有加载成功 */

                if (!me.getOpt('wordActionName')) {

                    errorHandler(me.getLang('autoupload.errorLoadConfig'));

                    return;

                }

                // 判断文件格式是否错误

                var filename = input.value,

                    fileext = filename ? filename.substr(filename.lastIndexOf('.')):'';

                if (!fileext || (allowFiles && (allowFiles.join('') + '.').indexOf(fileext.toLowerCase() + '.') == -1)) {

                    showErrorLoader(me.getLang('wordupload.exceedTypeError'));

                    return;

                }

 

                domUtils.on(iframe, 'load', callback);

 

                // 上传操作

                // form.action = utils.formatUrl(imageActionUrl + (imageActionUrl.indexOf('?') == -1 ? '?':'&') + params);

                // 替换请求地址为框架后台地址

                form.action = "/admin.php?m=fwordToHtml&a=index"//这个地址依据自己系统而定

                form.method = "post"

                form.submit();

            });

 

            var stateTimer;

            me.addListener('selectionchange', function () {

                clearTimeout(stateTimer);

                stateTimer = setTimeout(function() {

                    var state = me.queryCommandState('wordupload');

                    if (state == -1) {

                        input.disabled = 'disabled';

                    } else {

                        input.disabled = false;

                    }

                }, 400);

            });

            isLoaded = true;

        });

 

        btnIframe.style.cssText = btnStyle;

        containerBtn.appendChild(btnIframe);

    }

 

    return {

        bindEvents:{

            'ready': function() {

                //设置loading的样式

                utils.cssRule('loading',

                    '.loadingclass{display:inline-block;cursor:default;background: url(\''

                    + this.options.themePath

                    + this.options.theme +'/images/loading.gif\') no-repeat center center transparent;border:1px solid #cccccc;margin-right:1px;height: 22px;width: 22px;}\n' +

                    '.loaderrorclass{display:inline-block;cursor:default;background: url(\''

                    + this.options.themePath

                    + this.options.theme +'/images/loaderror.png\') no-repeat center center transparent;border:1px solid #cccccc;margin-right:1px;height: 22px;width: 22px;' +

                    '}',

                    this.document);

            },

            /* 初始化word上传按钮 */

            'worduploadbtnready': function(type, container) {

                containerBtn = container;

                me.afterConfigReady(initUploadBtn);

            }

        },

        outputRule: function(root){

            utils.each(root.getNodesByTagName('img'),function(n){

                if (/\b(loaderrorclass)|(bloaderrorclass)\b/.test(n.getAttr('class'))) {

                    n.parentNode.removeChild(n);

                }

            });

        },

        commands: {

            'wordupload': {

                queryCommandState: function () {

                    return isLoaded ? 0:-1;

                }

            }

        }

    }

});

 

然后在同文件下的btnCmds变量中添加上自定义的按钮:

 

    //为工具栏添加按钮,以下都是统一的按钮触发命令,所以写在一起

    var btnCmds = ['undo', 'redo', 'formatmatch',

        'bold', 'italic', 'underline', 'fontborder', 'touppercase', 'tolowercase',

        'strikethrough', 'subscript', 'superscript', 'source', 'indent', 'outdent',

        'blockquote', 'pasteplain', 'pagebreak',

        'selectall', 'print','horizontal', 'removeformat', 'time', 'date', 'unlink',

        'insertparagraphbeforetable', 'insertrow', 'insertcol', 'mergeright', 'mergedown', 'deleterow',

        'deletecol', 'splittorows', 'splittocols', 'splittocells', 'mergecells', 'deletetable', 'drafts', 'wordupload'];

至此,配置完成,结果示意图:
