Javascript Onload event for Default pages with Master Pages
I have an asp.net website and I have created a default page (Default.aspx) with MasterPage. Like this i have created many pages (.aspx) with the same MasterPage.
Now i want to write a javascript body onload event only to Default.aspx. How can i do this? because body tag is in master page. but i want to use it only to Default.aspx.
in the cs file put following line
ClientScript.RegisterStartupScript(ClientScript.GetType(), “onLoad”, “fnTest()”, true);
In aspx file put following line
Call Server Side methods from JavaScript
Some times we need to call server side function from Javascript function.For example,callig a PoupWindow(with value from code behind) on HyperLink click.
This must be implemented by creating a additional request to the web server and that’s the only way to invoke methods on the server. Page methods are used for this.
What is PageMethod?
A PageMethod is a public static method that is exposed in the code-behind of a page and can be called from the client script. PageMethods are annotated with [System.Web.Services.WebMethod] attribute.
The code is simple..
Server side function
CSS, JavaScript from Code Behind
CSS from Code Behind
gv_Unassigned.Rows(gv_Unassigned.SelectedIndex).Style(“Color”) = “White”
Me.div12.Style(“overflow-x”) = “hidden”
JavaScript From Code Behind
Response.Write(“<script>”)
Response.Write(“window.open(‘” & TrackUrl & “‘,’_blank’);”)
Response.Write(“</script>”)
JavaScript..Print contents in a DIV
PRINT WATEVER YOU WANT IN A DIV, ON A BUTTON CLICK.
Aaron says “Create a div around the content you want to print”.
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
ButtonPrint.Attributes.Add(“onclick”, “javascript:CallPrint(‘divPrint’);”)
end sub
<script language=”javascript”>
function CallPrint(strid) {
var prtContent = document.getElementById(strid);
var strOldOne = prtContent.innerHTML;
var WinPrint = window.open(”, ”, ‘left=0,top=0,width=1,height=1,toolbar=0,scrollbars=0,status=0′);
WinPrint.document.write(prtContent.innerHTML);
WinPrint.document.close();
WinPrint.focus();
WinPrint.print();
WinPrint.close();
prtContent.innerHTML = strOldOne;
}
</script>
Strid should be the ID of the DIV.
Dont forget runat=”Server”
