如何编写RegEx为每个图像创建一个javascript数组？

Question

I am trying to create a list of images. 我正在尝试创建图像列表。 I'm getting an ajax object back with the markup in a string. 我得到一个带有标记的ajax对象字符串。 Is there a way to use regular expressions in javacript to get each image? 有没有一种方法可以在Javacript中使用正则表达式来获取每个图像？ Is there another approach that is easier? 还有另一种方法更容易吗？

The part of the AJAX Response I want is at the bottom 我想要的AJAX响应部分在底部

<script>addRow("..","..",1,"646 B","10/4/14 10:09:49 AM");</script>
<script>addRow(".DS_Store",".DS_Store",0,"6.0 kB","10/4/14 10:18:24 AM");</script>
<script>addRow("Adobe_ad_728x90.jpg","Adobe_ad_728x90.jpg",0,"27.9 kB","10/4/14 10:00:39 AM");</script>

You can simply leverage the HTML parsing capabilities of the browser. 您可以简单地利用浏览器的HTML解析功能。 Your code sample is too long and I did not read it, but here's what can be done. 您的代码示例太长，我没有阅读，但是可以这样做。

var someHtml = '<ul><li><img src="test.jpg"></li></ul>',
    dom = parseHtml(someHtml),
    images = dom.querySelectorAll('img');

//log the src attribute of every image
[].forEach.call(images, function (img) {
    console.log(img.src);
});

//Returns a document fragment which contains the parsed nodes
function parseHtml(html) {
    var parserEl = document.createElement('div'),
        frag = document.createDocumentFragment();

    parserEl.innerHTML = html;

    [].forEach.call(parserEl.childNodes, function (node) {
        frag.appendChild(node);
    });

    return frag;
}
