Trigger the C# Click event with JavaScript fire function

Hi there, I could use a bit of assistance. My goal is to allow users to log in by hitting the "Enter" key on their keyboard. While I've successfully detected when the "Enter" key is pressed in my JavaScript code, I'm struggling with how to call my C# function. I understand that JavaScript runs on the client side and my C# code is on the server side, so I need some sort of PostBack mechanism. However, I haven't been able to get it to work consistently across all browsers.

This is the code I have written so far:

A button ...

<asp:Button ID="Button2" CssClass="btn" runat="server" type="submit" Text="Sign in"
                    OnClick="btnSubmit_Click" />

And here's my JavaScript:

$(document).keypress(function (e) {

    var target = document.getElementById("MainContent_Button2");

    if (e.which == 13) {
        __doPostBack('btnSubmit_Click', 'sender, null');
    }
});

Could you kindly point me in the right direction?

Answer №1

Have you considered using JavaScript to trigger the button click instead?

document.getElementById('MainContent_Button2').click(); return false;

Alternatively, if you are utilizing jQuery:

$("#MainContent_Button2").click();

You can try this approach:

$(document).keypress(function (e) {

    var target = document.getElementById("MainContent_Button2");

    if (e.which == 13) {
        document.getElementById('MainContent_Button2').click(); return false;

    }
});

I have not tested the above method personally, but I have successfully implemented a similar solution multiple times. Typically, I have a hidden button on the page, and when the user presses the enter key, I invoke the button click event using JavaScript.
