Textbox updated by another textbox data 1

[Scope72]

I have 2 textboxes (txtPrice, txtPercent). What I need to do, is update the txtPrice box without submitting the page/form.

When the txtPercent is changed, I would like to call a function which would then take the txtPrice value and multiply it by txtPercent and add that back into the txtPrice. Then I need to update the txtPrice box without submitting the page.


<td align="right"><?php print "Price" ?>:</td><td><input type="text" name="txtPrice" size="15" value="<?php print $txtPrice?>" />

<td align="right"><?php print "Percent" ?>:</td><td><input type="text" name="txtPercent" onChange="updatePrice()" size="15" value="<?php print $txtPercent?>" />



function updatePrice(txtPrice, txtPercent)
{
var newPrice;

newPrice = (txtPrice * txtPercent) + txtPrice;
document.GetElementById('txtPrice').value = newPrice
}


Thanks in advance for any help.

Then the PHP forum s not the place to ask this. If you need to perform calculations on the fly, I suggest Javascript, which it seems is what you are doing, however, the name of your function is wrong, as Javascript is case sensitive. GetElementById is different to [red]g[/red]etElementById. Also your function takes 2 parameters yet you pass none.

If you need specific help with JS I suggest posting in forum216 for more detailed answers.

As it stands the question is off topic for this forum.
