E9-根据主表选择框值判断改变主表、明细表字段的属性

一、流程表单开发过程中，标准的属性联动功能无法满足特定情况下的字段属性联动功能时，使用了以下JavaScript代码进行控制。

二、代码实现了根据表单字段的值动态显示或隐藏特定字段，同时修改字段的属性。这在需要根据用户输入动态调整表单显示

三、代码如下（供参考）

// 将字段名称转换为字段ID
var sfcsfy = WfForm.convertFieldNameToId("sfcsfy");
var hdhylx = WfForm.convertFieldNameToId("hdhylx");
var yjhcprs = WfForm.convertFieldNameToId("yjhcprs", "detail_2");
var yjnbrs = WfForm.convertFieldNameToId("yjnbrs", "detail_2");
var hyzt = WfForm.convertFieldNameToId("hyzt", "detail_2");
var hycd = WfForm.convertFieldNameToId("hycd", "detail_2");
var dyhybh = WfForm.convertFieldNameToId("dyhybh", "detail_3");

// 在文档加载时执行
jQuery(document).ready(function() {
    // 绑定字段变更事件
    WfForm.bindFieldChangeEvent(sfcsfy, function(obj, id, value) {
        toggleFieldVisibility(value);
    });
    WfForm.bindFieldChangeEvent(hdhylx, function(obj, id, value) {
        toggleDyhybhVisibility(value);
    });
    WfForm.registerAction(WfForm.ACTION_ADDROW + "2", function(index) {
        var sfcsfyValue = WfForm.getFieldValue(sfcsfy);
        toggleFieldVisibility(sfcsfyValue);
    });
    // 初始化字段可见性
    var initialSfcsfyValue = WfForm.getFieldValue(sfcsfy);
    toggleFieldVisibility(initialSfcsfyValue);

    var initialHdhylxValue = WfForm.getFieldValue(hdhylx);
    toggleDyhybhVisibility(initialHdhylxValue);
});

// 根据值切换字段可见性
function toggleFieldVisibility(value) {
    var detailRows = WfForm.getDetailRowCount("detail_2");
    var fieldNames = [yjhcprs, yjnbrs, hyzt, hycd];
    if (value == "1") {
        fieldNames.forEach(function(field) {
            changeAttr(field, 2, detailRows);
        });
        $(".ptoc").hide();
    } else {
        fieldNames.forEach(function(field) {
            changeAttr(field, 3, detailRows);
        });
        $(".ptoc").show();
    }
}

// 根据值切换字段可见性
function toggleDyhybhVisibility(value) {
    var detailRows = WfForm.getDetailRowCount("detail_3");
    if (value == "0") {
        changeAttr(dyhybh, 2, detailRows);
        $(".ptoc").show();
    } else {
        changeAttr(dyhybh, 3, detailRows);
        $(".ptoc").hide();
    }
}

// 改变字段属性
function changeAttr(id, viewAttr, row) {
    if (row != 0) {
        for (let i = 0; i < row; i++) {
            WfForm.changeFieldAttr(id + "_" + i, viewAttr);
            WfForm.changeFieldAttr(id + "_" + i, 4, viewAttr === 3);
        }
    } else {
        WfForm.changeFieldAttr(id, viewAttr);
        WfForm.changeFieldAttr(id, 4, viewAttr === 3);
    }
}

// 在文档加载时执行
