SlideUp by jQuery
<p>I'm trying to slideUp part of page by jQuery.
I use this code</p>

<p><code>$("#FirstPage").slideUp(1000);</code></p>

<p>I will hide FirstPage part of page,but not by time,I mean that it will hide suddenly not by 1000 ms.</p>

<p>the following code is FirstPage part,which should be hide after 1000ms and with slideUp.</p>

<pre><code>&lt;div id="FirstPage"&gt;
    &lt;div id="Login"&gt;
        &lt;form method="post" id="LoginForm"&gt;
        &lt;br /&gt;
        &lt;input type="text" name="username" id="username" /&gt;
        &lt;br /&gt;
        &lt;input type="password" name="passowrd" id="password" /&gt;
        &lt;br /&gt;
        &lt;input type="checkbox" name="invisible" value="TRUE" id="invisible" /&gt;
        &lt;br /&gt;
        &lt;img src="" /&gt;&lt;input type="text" name="captcha" disabled="true" style="display: none"
            id="captcha" /&gt;
        &lt;br /&gt;
        &lt;input type="button" value="Login ..." onclick="Ajax_Login()" /&gt;
        &lt;/form&gt;
    &lt;/div&gt;
    &lt;div class="OtherFeaturBig" id="WindowsVersion"&gt;
        &lt;img src="http://localhost/Files/Images/02.jpg" /&gt;
    &lt;/div&gt;
    &lt;div class="OtherFeaturBig" id="Advertisment"&gt;
        &lt;img src="http://localhost/Files/Images/02.jpg" /&gt;
    &lt;/div&gt;
    &lt;div class="OtherFeaturSmall" id="AboutUs"&gt;
        &lt;img src="http://localhost/Files/Images/03.jpg" /&gt;
    &lt;/div&gt;
    &lt;div class="OtherFeaturSmall" id="ContactUs"&gt;
        &lt;img src="http://localhost/Files/Images/03.jpg" /&gt;
    &lt;/div&gt;
&lt;/div&gt;
</code></pre>
