javascript - Javascript 中的正则表达式困惑

Question

我正在尝试得到这个:

<select name="id" onchange="window.location=('viewforum.php?id='+this.options[this.selectedIndex].value)">
    <optgroup label="Test category">
        <option value="2">New forum</option>
        <option value="3" selected="selected">New forum</option>
        <option value="4">New forum</option>
        <option value="5">New forum</option>
        <option value="1">Test forum</option>
    </optgroup>
</select>

来自此:

<div>
    <label>
        <span>Jump to<br></span>
        <select name="id" onchange="window.location=('viewforum.php?id='+this.options[this.selectedIndex].value)">
            <optgroup label="Test category">
                <option value="2">New forum</option>
                <option value="3" selected="selected">New forum</option>
                <option value="4">New forum</option>
                <option value="5">New forum</option>
                <option value="1">Test forum</option>
            </optgroup>
        </select>
        <input type="submit" value=" Go " accesskey="g">
    </label>
</div>

我的正则表达式是这样的:

qJumpHTML.replace(/.*\<select|\<\/select*/gi,''); 

给了我这个:

<div>
    <label>
        <span>Jump to<br></span>
            name="id" onchange="window.location=('viewforum.php?id='+this.options[this.selectedIndex].value)">
        <optgroup label="Test category">
            <option value="2">New forum</option>
            <option value="3" selected="selected">New forum</option>
            <option value="4">New forum</option>
            <option value="5">New forum</option>
            <option value="1">Test forum</option>
        </optgroup>
        >
        <input type="submit" value=" Go " accesskey="g">
    </label>
</div>

那么，我需要在正则表达式中更改什么才能获得我想要的字符串？来自所述字符串？

Answer 1

试试这个:

var d = document.createElement('div');
d.innerHTML = qJumpHTML;
var result = d.getElementsByTagName('select')[0].outerHTML;

THE PONY HE COMES而且你绝对没有任何借口，因为你是在 JavaScript 中工作!
