changing the disabled property of a submit button?

Copy linkTweet thisAlerts:

Hi,

I have the following JavaScript function :

function changeDisabled(formname,elementname)
{
document.formname.elementname.disabled = false
}

and it’s referenced from my web page like so :

<form>
<input type=”radio” name=”Quote” value=”1″ onclick=”changeDisabled(this.form,Submit)” />
<input type=”submit” name=”Submit” value=”Next” disabled=”true” />
</form>

Now when the radio button is clicked, there will be more than one, I want the submit button to be enabled. For some reason this isn’t working at the moment. But then I don’t really know a lot about JavaScript, and I just cobbled this together from various places.

Anyone know how to do this for me?

Thanks,

Adam

<i>
</i>&lt;body&gt;
&lt;script&gt;
function changeDisabled(formname,elementname){
var obj = eval('document.'+formname+'.'+elementname);
obj.disabled = false;
}
&lt;/script&gt;
and it's referenced from my web page like so :

&lt;form name="form1"&gt;
&lt;input type="radio" name="Quote" value="1" onclick="changeDisabled('form1','btnSubmit')" /&gt;
&lt;input type="submit" name="btnSubmit" value="Next" disabled="true" /&gt;
&lt;/form&gt;
