How to execute a function on load, resize and scroll event in jQuery?
In jQuery we can very easily bind load, resize and scroll events and run a function. The global window object has those events available. When we use jQuery then we can use jQuery wrapper methods to fire those events.
Following are different ways of executing a function on load, resize and scroll events:
The load event
$(window).load(function () { // define the function here });
The resize event
$(window).resize(function () { // define the function here });
The scroll event
$(window).scroll(function () { // define the function here });
We can combine all the events using jQuery on method. The method on binds all the events and allows one callback:
$(window).on("load resize scroll",function(e){ // define the function here });
If we want to separate the callback function for each event using on method we can do the following:
$(window).on({ load:function(){ }, resize:function(){ }, scroll:function(){ } });
We can also use bind method to combine all the events:
$(window).bind("load resize scroll",function(e){ // define the function here });
If we want to separate the callback function for each event using bind method we can do the following:
$(window).bind({ load:function(){ }, resize:function(){ }, scroll:function(){ } });
