default selected option for html select using javascript in IE

Hello I have a select element and I am trying to set a default option for that select element. But my code isn't working in IE. Is there any way around for this??

if(objOption.value == selectedoption)
{ alert(objOption.value);
objOption.defaul开发者_开发百科tSelected = true;
}

I am able to retreive the option, and its value, but am unable to set the defaultSelected value.

As stated in the documentation, the defaultSelected property is only used if you click an <input type="reset" />.

To immediately select the <option>, you should also set the selected property to true.
