Steps to deactivate a JavaScript function once the page has undergone a Page.IsPostBack event

My current setup involves a simple div with the display set to none. Upon page load, I use $("#MyDiv").show(); to display the div after a delay, allowing users to enter information into the form and submit it using an asp.net button.

After submitting the form and reloading the page, the JavaScript function runs again, causing the div to reappear. How can I disable this function after postback?

I am aware that you can use the following code:

if (Page.IsPostBack){}

However, I am unsure of how to actually disable the function. Here is how my function currently looks:

function testpopup() {
        setTimeout(function () { $("#MyDiv").show(); }, 1500);
    };

Any suggestions on how to achieve this? Thank you.

Update: I have found a solution by setting a hidden input field with the value of "N" like this:

<input type="hidden" id="IsFormSubmitted" value="N" runat="server" />

Then I modified the function to check and update the input field value to "Y":

'

function Password() {
        var val = document.getElementById("IsFormSubmitted");
        if(val.value == "N")
        {
            setTimeout(function () { $("#MyDiv").show(); }, 1500);
            val.value = "Y";
        }
    }; 

Thank you for all the help and guidance :)

Answer №1

One alternative approach to consider is incorporating a HiddenField control within your aspx page to indicate whether the form has been submitted or not.

<asp:hiddenfield id="hfFormStatus" value="" runat="server"/>

When the submit button's OnClick event is activated, you can set a value for the hidden field such as

hfFormStatus.Value = "submitted";
. This value can then be evaluated in your JavaScript code to determine if the show() function should be executed.

Answer №2

There are more effective methods to achieve the desired outcome.
1. Avoid adding $("#MyDiv").show(); within the $(document).ready... function.

void Page_Load(object sender, EventArgs e)
{
    if(!Page.IsPostBack)
    {
       ScriptManager.RegisterStartupScript(this, this.GetType(), "showdiv", "$("#MyDiv").show();", true);
    }
}
  1. Place your div containing all controls inside an UpdatePanel.
