js正则表达式匹配到所有img图片和src

let matchReg = /<img.*?(?:>|\/>)/gi;  // 匹配图片中的img标签
let arr2 = this.form.content.match(matchReg);  //拿到标签中所有的img
let srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i // 匹配图片中的src
let data = [];
if (arr2 != null) {
  for (let i = 0; i < arr2.length; i++) {
    let src = arr2[i].match(srcReg);
    data.push(src[1]);           //拿到 src=后面的 "http：xxx"
  }
}

this.form.content表示所有的内容 比如：

<p><img src="http://192.168.2.5:2345/Image/.png/e9843f6272de138356c60df42cfb55ff.png" /></p>↵<p><img src="http://192.168.2.5:2345/Image/.png/b888221c3a71c362b5e2289dc973eba9.png" /></p>↵<p>两张图片</p>

则arr2 里面就是提取的img

0: "<img src="http://192.168.2.5:2345/Image/.png/e9843f6272de138356c60df42cfb55ff.png" />"
1: "<img src="http://192.168.2.5:2345/Image/.png/b888221c3a71c362b5e2289dc973eba9.png" />"

则src里面是

0: "src="http://192.168.2.5:2345/Image/.png/e9843f6272de138356c60df42cfb55ff.png""
1: "http://192.168.2.5:2345/Image/.png/e9843f6272de138356c60df42cfb55ff.png"

获取src=“xxx”即提取src[0] 获取http://xxx 即提取src[1]
