  repeated int32 items = 1;
} 

How do you set the repeated items field in javascript?

Answer 1

To set the repeated field in javascript,

You can use either setItemsList or addItems methods.

For example, to use setItemsList method

let customer = new Customer();
customer.setItemsList([12, 123, 1234]);

It will set the value of items to the javascript array.

Or for another example, to use addItems method

let customer = new Customer();
customer.addItems(123);

It will append the value of 123 to the list of items in the message.
