How to get the value of Label of a Table at client side ?

The backend name of Label Field is 'label' only. To get table name we have g_form.getTableName(). How to get the table label name as shown in below scrrenshot. Please suggest

Well, if you want to change the header title then you might have to use DOM which is not recommended.

For this purpose, we have type field on the form, right?

If you still want to go with DOM, then try utilizing the below scripts on change_request table.

Display Business Rule.

(function executeRule(current, previous /*null when async*/ ) {

    var chgType = current.type.getDisplayValue();
    var tblName = current.getClassDisplayValue();

    g_scratchpad.title = chgType + ' ' + tblName;

})(current, previous);

onLoad() Client Script

function onLoad() {

    var arr = top.document.getElementsByClassName('navbar-title-caption');
    arr[0].innerHTML = g_scratchpad.title;

}

Output:

In case, if it does not work then you can uncheck Isolate script check box in the client script and try again. See the below image for reference.

Hi,

you can use display business rule on your table + onLoad client script

Display BR:

(function executeRule(current, previous /*null when async*/) {

	// Add your code here
		g_scratchpad.tableLabel = current.getClassDisplayValue();

})(current, previous);

onLoad client script:

function onLoad(){
	alert(g_scratchpad.tableLabel);
}
