Javascript Help

[rfm1964]

“I’ve implemented the following JavaScript code on a Power Pages form page. In this setup, I’ve attached an alternate key to the emailaddress1 column in the contacts table. The purpose of this code is to display a warning on the page if a user attempts to add a duplicate email address. However, the current warning message states: ‘A record that has the attribute values Email already exists. The entity key emailDupChk requires that this set of attributes contains unique values. Select unique values and try again.’ Instead, I’d like to replace this verbose message with a more user-friendly one, such as ‘This is a duplicate contact.’ Despite viewing the script when the page loads using ‘view source,’ my alternate statement isn’t being recognized. Can you identify any issues in the code?

<script type="text/javascript">$(function() {

$('#MessagePanel').on('DOMSubtreeModified', function(){

var txtError = $('#MessagePanel').text();

if (txtError === ' A record that has the attribute values Email already exists. The entity key emailDupChk requires that this set of attributes contains unique values. Select unique values and try again.'){

$('#MessagePanel').text('This is a duplicate contact.');

alert('changed');

}

}); // 

});</script>

Hi rfm1964,

As per our understandings you wish to overwrite the text on the form for email validation.

You might have made an unnoticeable mistake which is extra white space in your default text

and JavaScript's === operator requires an exact match, including spaces.

Below is the corrected code for your need,

<script type="text/javascript">

$(document).ready(function() {

    $('#MessagePanel').on('DOMSubtreeModified', function() {

        var txtError = $.trim($('#MessagePanel').text());

        var originalMessage = 'A record that has the attribute values Email already exists. The entity key emailDupChk requires that this set of attributes contains unique values. Select unique values and try again.';

        if (txtError === originalMessage) {

            $('#MessagePanel').text('This is a duplicate contact.');

            alert('changed');

        }

    });

});

</script>

Hope this helps.

Thanks!

@Inogic 1. Thanks for the reponse and sorry for the belated reply. I got pulled to a different project. That javascript didn't work. I've since decided to try it using a web api following these directions. Do you have any experiance with this? How to: Use the portal Web API | Microsoft Learn

For some reason this doesn't catch the l label "MessagePanel" so it never changes to the alternate message.
