How do you reference a variable from inside an event listener?

You must Login before you can answer or comment on any questions.

I have the following scenario, and I would like to be able to use the array inside the event listener:

var array = [];
array.push( { id:1, value:"1", desc:"abc" } );
 
button.addEventListener('click', function( array ){
    alert( this.array.length );
});

How do I reference the array from inside the Event Listener, as this code is not functional?

Thanks guys....

You are just doing a simple mistake here. as long as the eventListener are in the same block or in same scope you can do like this

var array = [];
array.push( { id:1, value:"1", desc:"abc" } );
 
button.addEventListener('click', function( ){
    alert( array.length );
});
