后台上传图片,大小各异,为了让图片在微信小程序更好的的显示,进行了以下处理:
找到内容中的图片,去除原有的宽高属性,给图片加上的宽度最大100%,高度自适应的样式
formatRichTextImg = (html) => { let newContent= html.replace(/<img[^>]*>/gi,function(match,capture){ match = match.replace(/style="[^"]+"/gi, '').replace(/style\s*?=\s*?([‘"])[\s\S]*?\1/ig, ''); match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, ''); match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, ''); return match; }); newContent = newContent.replace(/\<img/gi, '<img style="max-width:100%;height:auto;display:block;"'); return newContent; }
