Hi,

I was wondering if anyone could answer a question. I'm trying to design a form that has a few fields in it. One of the fields is a combo box with only two options in it. On selecting one option I'd like to auto fill another field and prevent the user from changing the contents of the field. I've read faq215-135 regarding the onfocus method and it doesn't seem to be dynamic as ideally when the user chooses the other option from the combo box they can either enter a number or be able to click on a link that allows them to select the number and then fills that back into the field.

Any help would be gratefully appreciated.

Thanks

for ie6 and ns6.2, you can change the readonly property for the given text box using javascript. for example...

function updateText(strNewText)
{
  document.getElementById("txt1").value = strNewText;
  document.getElementById("txt1").readOnly = true;
}

where...

<input type=&quot;text&quot; id=&quot;txt1&quot; value=&quot;&quot;>

for older browsers, the above code will not work, but there are probably variations that will.

Thanks for the code, unfortunately it's being deployed on an intranet where the browser is IE 5 - just to be difficult

i don't have a copy of ie5 for testing, nor do i have any documentation on the features it supports, but if ie5 supports the readOnly property, then you should be able to change the above function a little and have it work.

try replacing the

document.getElementById("txt1")

with

document.all.txt1

.
