how to trig the window resize event in JavaScript?

Question

I have register a trigger on window resize. I want to know how can I trig the event to be called. for example , When hide a div, I want my trigger function can be called.

I found window.resizeTo() can trig the function, but is there any other solution?

Answer 1

Don't worry about triggering that event. I imagine you have something like:

window.onresize = function() {
    // do a load of stuff
};

Or something similar.

So strip out the "do a load of stuff" into a function like this:

window.onresize = function() {
    doALoadOfStuff();
};

function doALoadOfStuff() {
    //do a load of stuff
}

That way, rather than trying to trigger the resize event, you can just call the doALoadOfStuff function.

Answer 2

Simply call window.onresize();

Answer 3

If you're using jQuery you can just use:

$(window).resize(function() {

// do stuff

});

jQuery .resize()
