Hello,

Currently I have a requirement to update an HTML element present on a Catalog Item based on what the user inputs in the fields below. See screenshot:

Basically, if a user types 'ServiceNow' in the Notification Title field, the phrase "THIS IS A TEST" will be updated to read "ServiceNow". I would imagine this requires an onChange client script and some JavaScript, but it's my first time creating functionality like this and some direction would be great. Thank you!

Based on some googling, im trying to utilize DOM Manipulation by using document.getElementById() in an on change client script. On paper I feel like this should be working, but it still is not. Any help would be great!

 

Client Script

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading) {
        return;
    }

    //Get value of Notification Title field
    newValue = g_form.getValue('announcement_title');

	//Get ID of html element being replaced
    var myDiv = document.getElementById('div_announcement_title');

	//Replace html element with user entered text
    myDiv.innerHTML = newValue;
	
}

 

HTML

<div class="announcement-wrapper ng-scope">
<div class="ng-scope" style="background-color: #006ed5; color: #ffffff; text-align: left;">
<div class="announcement-container linktype-none">
<div class="text-container">
<div class="icon-title" style="justify-content: flex-start;">
<div class="icon">&nbsp;</div>
<div id="div_announcement_title" class="title-announcement ng-binding announcement-left">THIS IS A TEST</div>
</div>
<p id="p_announcement_summary" class="content ng-binding">Check out this test info</p>
</div>
</div>
</div>
</div>
