JavaScript implements the method of executing the specified function after the webpage is loaded.

This example describes how to execute a specified function after a webpage is loaded using JavaScript. Share it with you for your reference. The specific analysis is as follows:

The following JS Code demonstrates how to call a specified function when a webpage is loaded, and dynamically add multiple functions for simultaneous execution using the second code.

You only need to specify a function for window. onload to automatically execute the MyCoolInitFunc function when page loading is complete.

<Script type = "text/javascript"> window. onload = MyCoolInitFunc </script>

If you want to execute multiple functions concurrently after page loading, you can use the following JS Code to implement

Function addLoadEvent (func) {var oldonload = window. onload; if (typeof window. onload! = 'Function') {window. onload = func;} else {window. onload = function () {oldonload (); func ();}}}

I hope this article will help you design javascript programs.
