1,110,625 | 1,110,626 | Google load jQuery and jQueryUI | <p>I'm trying to use the <a href="http://code.google.com/apis/ajaxlibs/documentation/#jquery" rel="nofollow">Google</a> to load jQuery for some pages and jQuery UI for others.
On the pages where I just need jQuery, I do the following:</p>
<pre><code><script src="http://www.google.com/jsapi"></script>
<script type="text/javascript">
function OnLoad() {
// my jQuery goodness
}
google.load("jquery", "1");
google.setOnLoadCallback(OnLoad);
</script>
</code></pre>
<p>And on the pages where I need jQueryUI, I also add this:</p>
<pre><code><link rel="stylesheet" type="text/css" href="/Library/jQuery/UI/Smoothness/css/smoothness/jquery-ui-1.7.2.custom.css">
<script type="text/javascript">
function OnLoadUI(){
$('div.tabs').tabs();
$('input.date').datepicker();
}
google.load("jqueryui", "1");
google.setOnLoadCallback(OnLoadUI);
</script>
</code></pre>
<p>Q: Am I doing anything wrong? It's working, but I want to know if I'm writing code that doesn't make sense.
Q: Does Google have the various UI css themes? Or am I right in thinking that I need to serve up the smoothness theme myself? (It's not really a custom theme - it's just the default one).</p>

<p>Below is a quote from <a href="http://cplusplus.com/reference/stl/vector/erase/" rel="nofollow">cplusplus.com</a> for <code>erase</code> function of <code>std::vector</code>:</p>
<blockquote>
<p>This effectively reduces the vector size by the number of elements removed, calling each element's destructor before.</p>
</blockquote>
<p>So I tried to implement the same functionality by calling the destructor of the last duplicate element. The destructor of <code>m_data[position]</code> is unnecessary as it will be replaced by the next element.</p>
<p>The problem is that the code in the destructor of vector class <code>delete [] m_data</code> will also call the destructors for each element which will cause double deletion of memory and crash.</p>
<p>Can anyone help to write the correct erase function for my vector class?</p>
