jasmine-jquery toBeDisabled not working

Question

I have got following html

<a disabled="disabled"><img alt="First" src="/Content/Images/Grid/disabledFirst.png"></a>

And I run following expect on this html

expect($(element)).toBeDisabled()

where element is the selector for above html. The expect fails. Further investigation lead to following code in jasmine-jquery-1.3.1.js

toBeDisabled: function(selector){
      return this.actual.is(':disabled');
    },

which for some reason is returning false. I'm sure I'm missing something very basic here but just not able to spot it.

Answer 1

This fiddle shows that jQuery only finds inputs not anchors when using :disabled. It's understandable because the anchor element doesn't have the disabled property
