Is it possible to get the value of a DOM select element in IE6?


So I'm having a cross-browser JavaScript issue.

I've got a <select> DOM element that has some descendent <option> element with selected=true.

In Firefox, I can just do select_elt.value to get the value of the selected option, but this seems not to work in IE6 (which I need to support).

I tried to iterate through the select_elt.getElementsByTagName('option') to find the selected <option>, which I could do, but option_elt.value still doesn't give me the value of that option.

So what is the appropriate way to get the value of an option or select element in IE6 (yes, I know I should switch to jQuery or some other cross-platform library, and I may yet, but now I'm curious about how this is done at all in IE6)?


Solution

  • This is the most cross-browser compatible way (in my experience) to do that:

    var mySelect = document.getElementById('mySelect');
    alert(mySelect.options[mySelect.selectedIndex].value);
