javascript undefined error from form input radio button
I have a pop up window which lists images using a form and radio buttons.
When i click a radio button, the function is called which should pass back to the parent window.
I keep getting 'undefined' as the value which means to me that the variable hasn't been set.
How do i get around this error?

if($file == "." || $file == ".." || $file == "index.php" )
continue;
$myfile = $file;
echo '<input type="radio" name="details" value="'.$myfil开发者_StackOverflowe.'" onClick="sendValue(this.form.details);" />'.$file.'<br />';
}

Why not just send the radio button value directly to the function, rather than the full radio button reference:
HTML
<input type="radio" name="details" value="1" onClick="sendValue(this.value);" />
<input type="radio" name="details" value="2" onClick="sendValue(this.value);" />
Javascript
function sendValue(val){
alert(val);
if(window.opener && !window.opener.closed) {
// do something with the parent window
}
}
In action here.
