Tips for executing a script on the "body" using "body onload=myfunc()" in an ASP.NET content page

I have included my script "myscript.js" in the master page. Now, in a content page, I want to load myscript() on startup (body onload).

Is there a way to accomplish this?

Answer №1

There are two ways to achieve this:

Page.RegisterStartupScript

  if (!IsStartupScriptRegistered (key))
  {
      String script = "<script type=\"text/javascript\">" +
        "alert('Hello World');</" + "script>";
      RegisterStartupScript(key, script);
  }

Alternatively, you could utilize the JQuery library and include the function call within the document.ready function

http://jquery.com/

 $(document).ready(function(){
   // Insert your function call here

 });

Answer №2

Here's a tip on how to add an onload client-side event to the body tag of the master page:

In the master page:

<body id="PageBody" runat="server">

In the content page:

HtmlGenericControl body = (HtmlGenericControl)Master.FindControl("PageBody");

body.Attributes.Add("onload", "doSomething();");`

Answer №3

To fulfill this task, I rely on a ContentPlaceHolder placed within the master-page. This approach allows me to selectively include certain scripts in the <head> section as needed.

Answer №4

Include the onLoad event in your Masterpage to utilize the form.

Answer №5

Make sure to set the id and server attribute to "runnat" in the body tag of your master page.

<body runat="server" id="body_master">

In the pageLoad event of your aspx .CS file, add the following code:

HtmlGenericControl body = this.Master.FindControl("body_master") as HtmlGenericControl;

body.Attributes.Add("onLoad", "SessionTimeOuts();");

Ensure that the SessionTimeOuts() function is defined in your .aspx file.

Thank you
