I want help from all you wonderful guys. I want to know how can we free memory occupied by an Array. That means all the elements associated with this array should be deleted.
i dont think he is looking for such a processor consuming way of deleting the memory. i think delete keyword works better for his needs. or basically setting the array to null.

window.onload = function() {
var bigArray = [];
bigArray2 = [];
for ( var i = 0; i < 500; i++ ) { // creating 500 items into bigArray >>>
bigArray[ i ] = "Item" + i;
bigArray2[ i ] = "Item" + i;
}
/*
You can use the delete operator to delete variables declared implicitly but not those declared with the var statement.
Output Sample: */
delete bigArray; // ignore's the delete process.
alert( bigArray.length ); // outputs the same length
// either one of the following statement will work, if you have defined it using the var statement.
bigArray = null; // or:
// bigArray = []; // reset's all items...
delete bigArray2; // this one works and delete's the bigArray2 variable.
};
// -->
</script>

both ways will provide the same results, the only difference between the two procedure, is that when you use the delete operator, your variable will no longer be accessible within the function unless you redefined it.
Hope we've claimed your needs...
@serkan - welcome , you had a better solution compared to my first post.
wow i have created big javascript applications so far and yet i have never needed to delete something from memory. why do you need it?
We usually encounter this problem when working with embedded devices (settop boxes etc.) where there is very less memory. We need to free memory where ever its possible.
