javascript - 需要 DOM 操作帮助

Question

<div id="main">
<div class="navigate">
    <ul>
        <li>
            <a href="http://localhost/xm/index.php"><span>xm</span></a> &#187;
        </li>
        <li>
            <a href="http://localhost/xm/index.php?action=admin"><span>Admin</span></a> &#187;
        </li>
        <li>
            <a href="http://localhost/xm/index.php?action=admin;change=name;random02342=randomvaluetoo320230"><span>change</span></a>
            .......

从这个 html 代码中，我必须在变量中获取随机生成的数据“random02342=randomvaluetoo320230”，这也是随机生成的 random0234 和随机值。我如何通过 Javascript（或非 jquery）实现这一点？

编辑：random02342 和 randomvaluetoo320230 是在服务器端随机生成的。所以就像每次新哈希一样 1stHash4324kjkjdas324324=And2ndAnotherHash324324asd23432

Answer 1

这会得到它，尽管它可能不会因优雅而赢得任何奖项：

var m = document.getElementById('main').innerHTML.match(/random(\d+)=randomvaluetoo(\d+)/);
// m[1] and m[2] are the two random values.

Answer 2

var first, second;

var q = $('.navigate ul li a[href*="change=name"]').attr('href').split(';').filter(
    function() {
        return this.contains('random');
    }
).join().replace(/[a-zA-z]/g, '').split('=');

first = q[0];
second = q[1];

Answer 3

based on your comment:

var value = $('selector').attr('href').split(';')[2].split('=');

this will give you value[0] - name, and value[1] - value However this is only if there 3 query params and the random one is the third

Also this might be usefull Parse query string in JavaScript
