if (typeof window.onload != 'function') {

Pastebin.com is the number one paste tool since 2002. Pastebin is a website where you can store text online for a set period of time The reason it is done this way is because you can't simply put 3 methods inside of window.onload itself. So what is commonly done is calling multiple functions from within an anonymous function. On subsequent window.onload assignments, window.onload does exist, so whatever it holds will be wrapped up with the new function. And so the list grows. If this kind of thing isn't a compelling reason to learn how to progam in a functional style, I don't know what is The way this works is relatively simple: if window.onload has not already been assigned a function, the function passed to addLoadEvent is simply assigned to window.onload. If window.onload has already been set, a brand new function is created which first calls the original onload handler, then calls the new handler afterwards

window.onload = function () { if (typeof jQuery ..

If window.onload has already been set, a brand new function is created which first calls the original onload handler, then calls the new handler afterwards. Isn't that beautiful? So, if you already have a script that uses the onload event handler, you don't need to dig it out and change it, unless you want to If you deal with more than external JavaScript file on a web page, it is only a matter of time before you run into a problem with window.onload. If two scripts each use window.onload, then the first function gets overwritten by the second. The Problem. Most scripts need to wait until the document is ready to start performing duties if (typeof window.onload != function ) {} , 我刚开始看《javascript DOM编程艺术》 window.onload for executing as soon as page loads Window.onload function we can use to perform some task as soon as the page finishes loading. This JavaScript function is used in different condition like displaying a print page or directing focus ( keeping the crusher blinking ) to user input field as soon as the page is loaded. The other way to achieve the same result is by using onload. The functions are run in the order they are assigned. With the above, function Func_Name_A() will run first, then Func_Name_B(), and after that Func_Name_C(). If the body tag has an onload attribute, it will run before any of the functions assigned to the onload queue with AddOnloadEvent(). Here is the code for a complete example

onload=function(){} considered harmful Harmful pattern. There seems to be a new pattern appearing on the web — attaching window load listener through undeclared assignment:. onload = function(){ /* */ }; I'd like to explain why it's a good idea to avoid it.. A conventional approach to perform this task is to explicitly assign to window.onload property typeof operand or typeof (operand) There are six possible values that typeof returns: object, boolean, function, number, string, and undefined. The following table summarizes possible values returned by the typeof operator

JS addLoadEvent问题 function addLoadEvent(func) { var oldonload = window.onload; if (typeof w 我来答 新人答题领红 The IF function is used to run a logical test, and react differently depending on whether the result is TRUE or FALSE. The first argument, logical_test, is an expression that returns either TRUE or FALSE.Both value_if_true and value_if_false are optional, but at least one of them must be provided. The result from IF can be a value, a cell reference, or even another formula function init {} window. onload += init; But that won't work. One approach I found on Simon Incutio's blog (which is used by the original LightboxJS script ) involves using a method that safely attaches an event handling method to the onload event without overwriting existing event handlers

What's wrong with window

Meridian Global - Core Domain Something went wrong. Your event ID for this error is ce26adfe-949e-4f88-8757-4423ded953df Here's a way to use window.onload that won't break other scripts that also need to use it: Store the current value of window.onload before you set the new value, then call it as part of your own initialization. I've written this short helper function to do the job for you

Internet Explorer 6 reports a state of loading while the document is parsing, constructing the DOM and loading any images. I made a small experiment polling document.readyState for either the loaded or complete states. Comparing the results from similar experiments for bottom script and the defer technique make it clear that document.readyState reports neither loaded or complete states until. window.onload=function(){ runsomefunction()} The limitation with the above approach is that multiple calls to window.onload on the same page causes all but the last one to be adopted, with (typeof timestamp == 'undefined'){ //if browsers don't support requestAnimationFrame,. window.onload. The load event on the window object triggers when the whole page is loaded including styles, images and other resources. This event is available via the onload property. The example below correctly shows image sizes, because window.onload waits for all images

  1. This method is a shortcut for .on( load, handler ).. The load event is sent to an element when it and all sub-elements have been completely loaded.

In the latter case, the IF function will implicitly convert data types to accommodate. If we have more than one function, we have to use an anonymous function that calls the others, this time with parenthesis.
