Store Javascript function result into variable

Question

I am doing the following:

elemDrop: function(elem) {
    return elem;
},

elemAddRel: function(json) {

    var elem = this.elemDrop;

    console.log(elem);

    $(elem.item[0]).addClass('showTab').attr('rel', json.pageId);

},

However when i console.log 'elem', it just stores the entire function into a variable. How can i actually store the result of the function into the variable?

Please post the entire object code that these two functions are part of. this.chuckDrop could be initialized somewhere else in the said object. — OnesimusUnbound

I think your code snippet is wrong. Is this.chunkDrop a reference to this.elemDrop? — frm

You should be able to do:

var elem = this.chunkDrop();

The use of the brackets () will trigger the function and return the result rather than setting the variable equal to the function itself.

So you need to execute the function by this.chunkDrop();
