Change text fields background colour if negative number using Jquery/CSS
- by Dan C
Hi,
I have the following text input on a budget calculator form which displays the final balance...
<tr><td align="right"><b>Balance: £</b></td><td align="left"><input type="text" class="res" name="res" id="res" size="10" readonly="readonly"></td></tr>
How do I go about setting the background of the input to red using css and jquery if the value is a negative number?
I am sure this is very simple but I have scanned the net looking for a solution for ages.
Please can someone help?, my head hurts!
