Adding another window.onload event in the Javascript for ASP.NET

For example If we are using two user controls having window.onload() event, it gives a problem to load two window.onload event.

For this we have to use microsoft specific or require bloated libraries. Please go through below code, how it works with W3C-compliant browsers and with Microsoft IE.



if (window.addEventListener) // this is W3C standard
{
  window.addEventListener('load', exampleFunction(), false); // NB **not** 'onload'
} 
else if (window.attachEvent) // this is Microsoft specific
{
  window.attachEvent('onload', );
}

If you have any queries or suggestions, please fell free to ask in comments section.
