Determines whether window. onload is used multiple times and window. onload
Window. onload must have been used by everyone. It is executed during window loading. How can we determine if window. onload is used multiple times? Take a look at the following code
<Script> function onloadCallback () {// Todo} if (window. onload) {var onload_random = 'onload' + Math. random (); window [onload_random] = window. onload; window. onload = function () {window [onload_random] (); onloadCallback () ;}}else {window. onload = function () {onloadCallback () ;}}</script>
There can only be one onload. You can write the solution to one onload.
Or
Use window. attachEvent ("onload", your onload method) in ie)
Use window. addEventListener ("load", your onload method) in non-ie Environments)
In this way, add an onload event.
Windowonload () Problems
Add the following code to the Page_Load event:
ClientScript. RegisterStartupScript (ClientScript. GetType (), "ss", "<script> your function; </script> ");
Delete:
<Body onload = "layout JS functions">
