How do I "Remove All" multirow variable set rows using a client script?

[kevinharalson]

I need a client script for use in an onChange function to remove all rows from a multirow variable set.

Scenario

1. A user will select a CI in a catalog item, and add maximum rows to a multirow variable set based on max_rows attribute.
2. Then, the user realizes the wrong CI was selected, and changes the selected CI
3. Upon selection of a new CI, I need a client script to remove all rows from the multirow variable set and enable the "Add" button.

I have tried the following without success

• g_form.setValue(< mrvs name>, '');
• g_form.setValue(< mrvs name>, '[]');
• g_form.clearValue(< mrvs name>);

In all instances the information is removed, but the "Add" button remains disabled.

Okay. Check out the article of Willem. 

Mark my comment(s) as helpful if they had helped you.

Here it is listed as mobile only. Not an official source though.. https://sn.jace.pro/docs/scripting/glideform/#desktop-getcontrol You got this working in back end @asifnoor

Don't know that I have already mentioned this, but I have also tried the following.

Where 'b919a58b1b32dc10c1ff4159cc4bcbb4Add' is the element ID of the Add button.

g_form.setValue('variables.capacity_request_cpu', '[]');
g_form.setDisabled('b919a58b1b32dc10c1ff4159cc4bcbb4Add', false);
