Status: RESOLVED DUPLICATE of bug 662335

(Core :: DOM: Events, defect, P5)

Description

[Rob Apodaca]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)

In a form with an input and button present, if entering some text into the input element and pressing return, firefox triggers a click event on the first button (if any) in the form. That event object's explicitOriginalTarget property contains the button element instead of the input element. If no text is entered into the input and the enter key is pressed, the event object's explicitOriginalTarget property contains the input element.

Reproducible: Always

Steps to Reproduce:
For the given markup and js:
<script type="text/javascript">
  function clicker(evt){
   alert(evt.explicitOriginalTarget.tagName)
  }
</script>
<form action="/" method="post">
  <input type="text" />
  <button onClick="clicker(event)">Button</button>
</form>

--Case: With some text
1. Place focus on the text input.
2. Enter a string: "foo"
3. Press enter

--Case: With no text
1. Place focus on the text input.
2. Press enter
Actual Results:  
In the case of "With some text": the tagName is "BUTTON"
In the case of "With no text": the tagName is "INPUT"

Expected Results:  
In the case of "With some text": the tagName should be "INPUT"
In the case of "With no text": the tagName should be "INPUT"

We should remove explicitOriginalTarget.
