如何利用 drop子展示不同的形式,依据的是使用 j子在下降时的用户选择?

最佳回答

监测<代码>change 根据所选择的价值,隐藏或显示形式。

http://jsfiddle.net/84dNc/"rel=“nofollow> http://jsfiddle.net/84dNc/

/* use classes to maximize performance when hiding/showing */
form  { display: none; height: 100px; width: 100%; border: 1px solid gray;}
form.active { display: block; }

$( select ).change( function() {
    $( form.  + $(this).val()).addClass( active ).siblings( form ).removeClass( active );     
});

 

<select>
    <option value=""></option>
    <option value="a">a</option>
    <option value="b">b</option>
    <option value="c">c</option>    
</select>

<form class="a">
    Form A
</form>

<form class="b">
    Form B
</form>

<form class="c">
    Form C
</form>
