jQuery onchange select option
<p>Let's say I have this HTML:</p>

<pre><code>&lt;select id='list'&gt;
    &lt;option value='1'&gt;First&lt;/option&gt;
    &lt;option value='2'&gt;Second&lt;/option&gt;
    &lt;option value='3'&gt;Third &lt;/option&gt;
&lt;/select&gt; 
&lt;input type ="text" id="text"/&gt;
</code></pre>

<p>and then this JavaScript</p>

<pre><code> //other variables are also declared here
    var x1 = 5;
    var x2 = 10;
    var value = x1 * x2;
    var list_value =$("#list").change(function() {
             $(this).val();
 // just an example of how i want the function in the variable 
    });
    var nwval = value * list_value;
      $('#text').val(nwval);
// some long piece of code 
// i'm also using the list_value value somewhere in the long piece of code..
</code></pre>

<p>I want the val in the textbox to change as the user selects an option, I know it'll work if I wrap the change event around it, but is there any way to go about this while keeping it as that variable <code>list_value</code>?</p>
