send a jquery callback function inside a variable

Question

I have this jquery function

    function example(file, targetwidget, callback){

    $(targetwidget).load(file, {limit: 25}, function(){
        $(\"#widget_acco         


        

Answer 1

Since you are passing a text string you would need to eval it:

function example(file, targetwidget, callback){

    $(targetwidget).load(file, {limit: 25}, function(){
        eval(callback);
    });

Edit:

if you want to use call() you would have to do it like this:

function callback() {
    $("#widget_accordion").accordion({fillSpace: true});
}

function example(file, targetwidget, callback){

    $(targetwidget).load(file, {limit: 25}, function(){
        if(typeof(callback)==='function'){
            callback.call(this);
        }
    });

example('http://example.com/', "#divid", callback);

In order for call to work, you would have to pass a function and not a string. But by wrapping your jQuery expression inside of a function, it would be run when the function is called. Calling a function can be done with the .call() method.
