BUG: Internet Explorer Stops Responding When You Dynamically Insert Table That Contains <Input Type="Button"> (298974)


The information in this article applies to:

  • Microsoft Internet Explorer (Programming) 5.5
  • Microsoft Internet Explorer (Programming) 6.0
This article was previously published under Q298974

SYMPTOMS

Internet Explorer generates an access violation and stops responding (crashes) when you dynamically insert a table that contains the following

<input type="button">

into a Web page by updating the innerHTML of a div.

CAUSE

This behavior can occur if a mouse event is pending and you wipe out the control that initiated the mouse event before the mouse event returns.

RESOLUTION

Workaround 1

Instead of redrawing the entire table every time, insert a single row at a time into the existing table. To do this, use the insertRow() and insertCell() methods.

Workaround 2

Replace

<input type="button">

with the following tag:

<button></button>

STATUS

Microsoft has confirmed that this is a bug in the Microsoft products that are listed at the beginning of this article.
