On my ASP.NET page, there is a button that when clicked opens a modal dialog box through JavaScript. I need to determine how to proceed or cancel the post back based on the value returned by the modal dialog box. Can anyone provide guidance on how to achieve this?
To stop the button from automatically triggering a postback, include "return false;" in the onclick attribute.
Are you attempting to achieve this particular task?
<button id="myBtn" onclick="verifySelection()">Click Here!</button>
<script type="text/javascript">
document.getElementById('myBtn').onclick = function() {
var confirmation = confirm('Are you certain you want to proceed?');
if (!confirmation) return false;
};
</script>
function ClickHandler()
{
// perform necessary tasks;
if (certain criteria are met) return true; //carry on
else return false; //stop;
}
assign the OnClick function to "return ClickHandler()"
To add onto Wayne's advice, ensure to include 'return false;' within the modal presentation function. This will allow the postback to occur if it meets your criteria, or stop the submission process by returning false.
