How to get Values from Custom with Label Variable ? How to set limit of values and restrict submit

[S Deva]

There is a variable Custom with Lable for selecting multiple change requests. It should have at least 3 values before the submit form. 

I have added script : 

var Changes = g_form.getvalue("field_name").toString().split(',');

var changes_length = Changes.length;

if(changes_length>=3){

return true;

}

return false;

But this is always return false . How to achieve this can anyone please help ?

@S Deva It should be return false; in the if block. Please check below code:

function onSubmit() {
var changes = g_form.getValue('<FIELD NAME HERE>');
changes = changes.toString().split(",");

if (changes.length >= 3) {
g_form.addErrorMessage("Action aborted.");
return false;
}
}

Please mark as correct answer if this solves your issue

Its not working. Actually the length of the values is coming as "0" .

100% working solution.

You must validate that on in the widget (which is used in custom with label) it self. Create a new field (boolean) to store the validation result.

Use the new field in the on submit client script to abort the action.

Note:

On widget, to sent the value in new field use below syntax

$scope.page.g_form.setValue("<NEW FIELD HERE>", "<true/false validation result>");
