Javascript: Properly Setting A Text Area
<p>I have a text area and the problem is people are typing a large amount of text and I have it clearing out the value and forcing an N/A so I can force something to be entered.  How can I make the script below validate someone has already typed something (and not clear it out) but still clear out the N/A by default?</p>

<pre><code>&lt;textarea name="req_WhatMadeItDifficultToUse" cols="35" 
 onfocus="this.value = '';" 
 onblur="if(this.value == '') this.value = 'N/A';"   
 id="WhatMadeItDifficultToUse"&gt;N/A&lt;/textarea&gt;
</code></pre>
