My motto is to call a Java script function at the end of button click code behind. ie, firstly i need to execute the server side function after which my java script function should get invoked. My server side method is as follows
protected string SaveEmbedURL_click()
{
if (txtembedurl.Text != null)
{
School aschool = new School();
aschool.SchoolId = CurrentSchool.SchoolId;
aschool.EmbedUrl = txtembedurl.Text;
SchoolRespository.updateEmbedUrl(aschool);
return "true";
}
}
My Java script function is as follows
function SaveEmbedUrlClientSide() {
admin_CustomizeTheme.SaveEmbedURL_click(true);
$('#lbl_embedcode').removeClass('hide').addClass('show');
$('#embedCode').removeClass('hide').addClass('show');
CopyToClipboard("embedCode");
}

View 1 RepliesI have always been banging my head for this:
Why <a runat="server" onclick="CodeBehindFunction()"> does not work (in simple html without databound controls) even if we make it to run at server?
(I know we can always replace such anchor requirement with asp:LinkButton as it ultimately get rendered as anchor in html.)

View 5 RepliesI have a function in Code Behind, Can any one let me know "How would I call this function using javascript"?
View 4 RepliesI don't need to run the function every time the page loads!!
But, I would like to have the control when the function is to be called.
The only way I thought of is calling my function with OnLoad in the body tag and having a hidden field to be checked and then run the script accordingly.
e.g:
<body onload="ScrollToView();">
Is there a better way? For example, running the function from Page_InitComplete handler?
in aspx:
function checkFunction(no,name){
}
in cs:
string test_name ="hello";
StringBuilder Strname=new StringBuilder();
Strname.AppendLine("<td ><input type=checkbox onclick='checkFunction("+no+","+test_name+");' runat='server' name='checkbox_name' value='XX'</td>");
when i call the checkFunction(), i can't pass the 2 argument as there is error.
