How to use a jQuery function in my javascript source code?
<p>I'm very sorry to ask such an easy question for you. I can use a jQuery function in my html pages. But I do not know how to use one in my javascript source file? Please let me know.</p>

<p>Thank you in advance.</p>

<p>Edit: Currently , I use the following declaration at the head of my javascript source file.</p>

<pre><code>&lt;script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.2.3/jquery.min.js"&gt;&lt;/script&gt; 
</code></pre>
