check if field exists on page

[rkoya]

Hi,

I need to check if a specific field is on the page or not. It is put in dynamically, and is not always there. Is there a way to check it?

The input name is:

<input name="fldLocalExtrainAmount" type="text" id="fldLocalExtrainAmount" value="0" size="4" maxlength="1" onBlur="fnCalcLocalExtraTotalin (this.value);">

Thanks

if it is in a form you could use the document.<formname>.<fieldname> approach in an IF statement, alternatively you could use document.getElementByID instead.
