setting a value on a select element ambiguous

Reported by: Borre Owned by:
Priority: major Milestone: 1.4.3
Component: attributes Version: 1.4.2

Blocking: Blocked by:


given a select box:

<select id="test_dropdown">
  <option value="1">somevalue</option>
  <option value="2">1</option>

and given the statement


the second option will be selected. This seems to be unwanted behaviour (in my opinion, an option with a value attribute should have priority). The erroneous code seems to be located in jquery-1.2.6.js on line 419:

jQuery( "option", this ).each(function(){
	this.selected = (jQuery.inArray( this.value, values ) >= 0 ||
	jQuery.inArray( this.text, values ) >= 0);

I confirm this unwanted behavior. As per W3 standard regarding the 'value' attribute of OPTION:

"This attribute specifies the initial value of the control. If this attribute is not set, the initial value is set to the contents of the OPTION element."

It sounds like this was fixed in jQuery 1.3.

I'm sorry to say it was not. The problem still exists.

The solution that works for me is replacing jquery-1.3.1.js, line 462-465:

jQuery( "option", this ).each(function(){
	this.selected = (jQuery.inArray( this.value, values ) >= 0 ||
	jQuery.inArray( this.text, values ) >= 0);


var selectedFound = false;
jQuery( "option", this ).each(function(){
	selectedFound = selectedFound || (this.selected = (jQuery.inArray( this.value, values ) >= 0));

	jQuery( "option", this ).each(function(){
		this.selected = (jQuery.inArray( this.text, values ) >= 0);

This was resolved in 1.4. More tests here to confirm:  http://github.com/jquery/jquery/commit/879799fe955f01b85b59fd8a0096d415fc48df03
