Looking for advice on how to handle form processing in an asp.net page depending on whether the user's browser supports JavaScript. Specifically, I want to call JavaScript methods if available, and fallback to using code behind events if JavaScript is not supported. I already have a JavaScript code that sends form data to an ajax server page using jQuery, but unsure about how to trigger the appropriate method based on the browser's JavaScript capabilities.
Design the form to perform a postback and send the information without relying on JavaScript, then assign the click event to trigger your JavaScript function upon clicking the submit button. Utilize e.preventDefault() and e.stopPropagation() within the click event handler to stop the postback from occurring.
Add functionality to handle the enter key press event and prevent it from triggering a postback action as an additional measure.
