前端获取到后台数据不做处理就会出现下面问题图片视频超出视图显示不全

请添加图片描述
处理

//info 是富文本
<view v-if='info' v-html='replaceWhite(info)'></view>

调用下面方法

replaceWhite(html) { // 处理富文本默认图片，视频大小let newContent = html.replace(/<video[^>]*>/gi, function(match, capture) {match = match.replace(/style="[^"]+"/gi, '').replace(/style='[^']+'/gi, '');match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, '');match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, '');return match;}).replace(/<img[^>]*>/gi, function(match, capture) {match = match.replace(/style="[^"]+"/gi, '').replace(/style='[^']+'/gi, '');match = match.replace(/width="[^"]+"/gi, '').replace(/width='[^']+'/gi, '');match = match.replace(/height="[^"]+"/gi, '').replace(/height='[^']+'/gi, '');return match;});newContent = newContent.replace(/style="[^"]+"/gi, function(match, capture) {match = match.replace(/width:[^;]+;/gi, 'max-width:100%;').replace(/width:[^;]+;/gi,'max-width:100%;');return match;});newContent = newContent.replace(/<br[^>]*\/>/gi, '');newContent = newContent.replace(/\<video/gi,'<video style="max-width:100%;height:auto;display:inline-block;margin:10rpx auto;"').replace(/\<img/gi,'<img style="max-width:100%;height:auto;display:inline-block;margin:10rpx auto;"');return newContent;},
