30458 - Cannot clear text box using control.value = ""

Status: VERIFIED DUPLICATE of bug 27951

(Core :: DOM: Core & HTML, defect, P3)

Description

[Nicholas Cull]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; N; NT4.0; en-US; m14)
BuildID:    2000030308

Using DOM level 0, I need to be able to clear text boxes using code such as:

document.library.productcode.value = "";

This doesn't work in Mozilla when the content of the text box has been entered
or edited by the user.

Reproducible: Always
Steps to Reproduce:
1. Open Mozilla
2. Go to the test case that I'll attach shortly
3. Enter some text into the text boxes
4. Press the "Add" button


Actual Results:
The text boxes are not cleared. Some debugging code I put to test the value of
these boxes steps in and reports the current value of the text boxes.

Expected Results:
The text boxes should be cleared. The debugging code should not activate.

Additional Information:
It's worth noting that this only occurs when the content of the text boxes is
altered by the user. When content is set using either the value attribute in
HTML, or altered using Javascript, the problem does not appear.

Works Correctly On:
IE 5.01, Opera 3.61, Netscape 4.72
