radio button input

[zngo]

I just started learning javascript and I wanted to make an interface to the google search engine. I went on to implement the feature that filters languages and I found that I need to use a radio button set to do this.

I have looked around for ways to get values from radiobutton sets. I seem to always come across this one method..:

<input type=&quot;radio&quot; onClick=&quot;someFunction('value')&quot;>
// then the function would have the 'value' parameter..

I want to be able to (within js) use the value of the box that is checked. My method (that failed?) can be found here:

// the javscript part::
function searchgoogle(){
var url=window.document.googleform.url.value.split(&quot; &quot;
var output=&quot;&quot;;
var lang=&quot;&quot;;
var options=window.document.googleform.language.length;
for (i=0; i<=options; i++){
if (window.document.googleform.language){
lang = window.document.googleform.language.value;
}
}
for (i=0; i<=url.length; i++){
output+=&quot;+&quot;+url;
}
output=output.substr(1,output.length-11);
window.open(&quot;

http://www.google.com/search?q=&quot;+output+lang);

}

<!-- the html:: -->
<form name=&quot;googleform&quot;>
<input type=&quot;text&quot; name=&quot;url&quot;>
<a href=&quot;javascript:searchgoogle()&quot;>Search</a>&nbsp;|&nbsp;<a href=&quot;javascript:reseturl()&quot;>Reset</a>
<br />
<input type=&quot;radio&quot; name=&quot;language&quot; value=&quot;&lr=lang_en&quot;>English
<input type=&quot;radio&quot; name=&quot;language&quot; value=&quot;&lr=lang_de&quot;>German
<br /><br />/* Looking for features to add... */
</form>

lol, that didn't do much. I think I know what i need to find out.

Is there any way you can check on the condition of a radio button? like give it a test? Is there something like:

if (window.document.form.radiobutton[3].checked == true){
// blah blah blah
}

the site i showed you uses the function as a generic operator for all the buttons, but to check for one button, you can use...
if (document.formName.radioName.checked==true){
blah blah}

HOWEVER, that is for only one specific button, not multiple ones

and yes, the radioName[radio-index] works for all of them

Well, I played with this (FOR A FEW HOURS! ). loser.. yeah, well I decided to make a hidden element in the googleform form and make the onClick of the language radio button change the hidden element's value. when the actual function that opens the google search does its thing, it will append the value of the hidden element in the googleform form, making my script work fine, i think.

Thanks Greelmo for taking the time to look at my problem and for giving me the drive to solve this problem.
