所以，我正在尝试完全做到这一点，虽然它适用于 jsfiddle，但它不会在我尝试过的任何浏览器中......有什么想法吗？即使它是页面上唯一的东西，它也因任何原因拒绝工作。 http://jsfiddle.net/RWUdb/101/

<div>
<label>Device:</label>
<select name="Device" id="Device" class="" onclick="craateUserJsObject.ShowPrivileges();">
<option value="Select">--Select a Device--</option>
<option id="iOS" value="iOS">iOS Device</option>
<option id="macdesktops" value="macdesktops">Mac Desktop</option>
<option id="maclaptops" value="maclaptops">Mac Laptop</option>
<option id="pcdesktops" value="pcdesktops">PC Desktop</option>
<option id="pclaptops" value="pclaptops">PC Laptop</option>
</select>
</div>
<div class="resources" style=" display: none;"><select>
<option>-Select a Model-</option>
<option value="Touch">iPod Touch</option>
<option value="Nano">iPod Nano</option>
<option value="Classic">iPod Classic</option>
<option value="Shuffle">iPod Shuffle</option>
</select> <font color="red">*</font></div>
<div class="resources2" style=" display: none;">
<select>
<option>-Select a Model-</option>
<option value="iMac">iMac</option>
<option value="MacPro">Mac Pro</option>
<option value="Mini">Mac Mini</option>
</select> <font color="red">*</font>
</div>
<div class="resources3" style=" display: none;">
<select>
<option>-Select a Model-</option>
<option value="White">White Macbook</option>
<option value="Pro">Macbook Pro</option>
<option value="Air">Macbook Air</option>
</select> <font color="red">*</font>
</div>
<div class="resources4" style=" display: none;">
<input type="text" id="pcdesktops" placeholder="ie. Dell Optiplex 9010"/> <font color="red">*</font>
</div>
<div class="resources5" style=" display: none;">
<input type="text" id="pclaptops" placeholder="ie. Lenovo G580" /> <font color="red">*</font>
</div>

Javascript：

var Privileges = jQuery('#Device');
var select = this.value;
Privileges.change(function () {
if ($(this).val() == 'iOS') {
    $('.resources').show();
}
else $('.resources').hide();

if ($(this).val() == 'macdesktops') {
    $('.resources2').show();
}
else $('.resources2').hide();

if ($(this).val() == 'maclaptops') {
    $('.resources3').show();
}
else $('.resources3').hide();

if ($(this).val() == 'pcdesktops') {
    $('.resources4').show();
}
else $('.resources4').hide();

if ($(this).val() == 'pclaptops') {
    $('.resources5').show();
}
else $('.resources5').hide();
});

你把它附在

$(document).ready(function() {
 // your code
});

在你的脑海中添加这个：

<script src="http://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
