js字符串中获取img标签

<script>

      var content = '<P><img src="http://bbs.cn.yimg.com/user_img/200701/31/jisuanji986_117025184198149.jpg" mce_src="http://bbs.cn.yimg.com/user_img/200701/31/jisuanji986_117025184198149.jpg"></P>'
      let imgReg = /<img.*?(?:>|\/>)/gi //匹配图片中的img标签
      let srcReg = /src=[\'\"]?([^\'\"]*)[\'\"]?/i // 匹配图片中的src
      let arr = content.match(imgReg)  //筛选出所有的img
      console.log(arr)
      let srcArr = []
      for (let i = 0; i < arr.length; i++) {
        let src = arr[i].match(srcReg)
        // 获取图片地址
        srcArr.push(src[1])
      }
      console.log(srcArr)

  </script>
