Error In Javascript Closure

I have a modal dialog with a submit button, which when clicked caused the following code to execute: $('#addqueuebutton').on('click',function(){ var counter = 0; return fu

Solution 1:

You're assigning the wrong function to click. When you click, you initialise counter and then return the inner function.

You need to call the outer function and assign its return value to the second argument of on().

}); should be }());

Or, to make it clearer:

functioncreate_counter(){
    var counter = 0;

    returnfunction(){
        counter += 1;
        ...
        alert(counter);
    };
}

var counter_incrementing_function = create_counter()

$("#addqueuebutton").on("click", counter_incrementing_function);
