<h2>Summary</h2>
|
|
In Internet Explorer, when a event such as click on one element causes a change event on another element to trigger programmatically, any change event handler that was bound to that second element through onchange gets the click event instead of the change event.
|
|
|
|
<h2>Steps to reproduce</h2>
|
|
<p>
|
|
To demonstrate the issue, do one of the following:
|
|
</p>
|
|
<ul>
|
|
<li>Click the input to open the Datepicker, then select a date</li>
|
|
<li>Or press a number in the text field and blur</li>
|
|
<li>Or click a button below</li>
|
|
</ul>
|
|
<p>
|
|
Each will trigger change on the text input. The input has a handler bound in three different ways. Notice the difference when pressing a number in the input and bluring versus either selecting a date or pressing one of the first three buttons. In Internet Explorer, when the issue is present, 2 out of the three event objects are of type 'click' instead of 'change' and have the wrong corresponding srcElement/target when the datepicker or one of the first three buttons are clicked.
