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
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;
},
