获取字符串或div中img src路径

一、字符串——正则表达式

let allImage = [];
let str = "
这是个字符串
";
str.replace(/]*src=['"]([^'"]+)[^>]*>/gi, function (match, capture) {
  allImage.push(capture);
});
console.log(alllImage);

二、div——dom节点

//vue template

  
这是个字符串


//javascript
let allImage = [];
let imgDiv = this.$refs.img.getElementsByTagName("img");
imgDiv.forEach(i => {
  allImage.push(i.src)
});
console.log(allImage);
