Need help of clear a list collector variable

[Erica2]

Hello,

Could someone please suggest on how to clear/empty a list collector variable after form loaded using catalog client script?   I'm familiar UI Policies, but needed to learn using client script. 

Thank you

Hello @Erica2 

Greetings!

Could you please elaborate your question. I believe When the form is loaded, the list collector would be empty. because no selection is made by user 

refer below thread if it helps your scenario;

please mark the answer as correct and helpful if helped.

Hello @Ravi Chandra_K 

The list collector is currently uses for request approval.  Once selected values(approvers) have been sent, we would like to clear out the list so that user have an option to select additional approvers.

var variableName = 'list_collector_var';
g_form.setValue(variableName, []);
g_form.addInfoMessage('List collector variable cleared.');

Hello @Harish Bainsla 

I tried the following code, but I have no luck of getting it to works:

function onLoad() {

    var variableName = 'approverList';

    g_form.setValue(variableName, []);

    g_form.addInfoMessage('List collector variable cleared.');

}
