Javascript function question
- by Raj
I searched but couldn't find an answer to this seemingly easy question, so...
Suppose I have a loop in which I need to set callbacks. My callback function looks like this:
function callback(var1) { // code }
Now my loop is something like this:
for( //condition)
{
var x = something_different_each_time;
document.getElementById('foo').addEventListener('click', function() { callback(x); }, false);
}
Now it looks like even if the loop runs n times, the anonymous function is compiled only once -- and hence every invocation of callback is called with the same argument (even though x varies in the loop every time).
I must be missing something here.. any help is greatly appreciated! :)
