I need help with implementing a countdown timer in JavaScript. When the timer reaches 0 seconds, I would like the page to trigger the button1_click event handler.
Here's the scenario: I am working on a quiz engine where the quiz responses need to be submitted once the time runs out. This is where I need the button1_click event handler to come into play.
If you have any ideas or suggestions, please share them with me. Thank you!
To quickly submit a web form using ASP.NET, you can utilize the JS function provided by ASP.NET:
<script type="text/javascript>
function submitForm() {
__doPostBack('button_id','');
}
</script>
You can easily retrieve the ID of the button with the following code:
__doPostBack('<%= myButton.ClientID %>', '');
