Button from A tag can't be disabled

It seems to need something like this:

 $("#button").click(function () {
  if ($(this).attr("disabled")) return false;
 });

I need initialy disabled button with disabled state by using native UI methods.

This workaround only prevents click action.

• The "A" element seems to have no "native" UI method to prevent click action.
• The "BUTTON" element seems to have the "disabled" attribute to prevent click action.

• http://www.w3.org/TR/html401/interact/forms.html#adef-disabled

In IE8, when disabling the "A" element, the element seems to be grayed out, do not receive focus, but can be clicked.

I am running into this problem as well - but only in Firefox.

If I turn an "A" element into a jQuery UI button, then disable the button, then click on the button then:

• in IE8, the buttons click event handler will not be invoked (good)
• in Firefox 3.6.8, the buttons click event handler will be invoked (bad)

Same behavior is experienced if the button is disabled with .attr("disabled", "disabled").

Here is my sample code:

<a href="#" id="a1">Test</a>

<script type="text/javascript">

$(function() {

$('#a1').button().button("option", "disabled", true).click(function() { alert("clicked") });

});

</script>

It seems the "disabled" attribute of the "A" element does not prevent the click action

in IE8.0.6001.18943, Chrome 6.0.472.53, Safari 3.2.2(525.28.1), Firefox 3.6.6, Opera 10.53.

<a href="about:blank" id="a1" target="_blank" onclick="alert('obtrusive')" disabled="disabled">Test</a>

But it seems ".button({ disabled: true })" prevent the click action in IE8, not in other browsers.

$('#a1').button({ disabled: true });

jQuery( or jQuery UI) code may prevent the click action in IE8.

The "disabled" attribute of the "A" element (half-implemented in IE) may have something to do with this behavior.

alert( $("#a1").attr("disabled") === true )

• In IE8, this code shows "true".
• In other browsers, this code shows "false".

jQuery UI code may prevent the click action in IE8.

<A class="ui-button" disabled="disabled" onclick="alert('obtrusive')" href="about:blank" target="_blank">test</A>
