Convert HTML text area value to jqmath formula

I am new to jqmath; I have contained a textarea field in my HTML:

<textarea cols="30" rows="2" id="mathSrc1"></textarea>

I will set mathematical formula in the text area so that it will be displayed in <div> tag:

<div id="mathTgt1"></div>

This code is available in http://mathscribe.com/author/jqmath.html. But I don't know how to use it. Please help me.

Thank you.
