The below code is enough for clear a single line.

var OrderLineClear = screens.ActionButtonWidget.extend({
    template: "OrderLineClear",

    button_click: function(){
    var self = this;
    this.clear_button_fun();
    },

    clear_button_fun(){
    var order = this.pos.get_order();
    order.remove_orderline(order.get_selected_orderline())
    },
});
screens.define_action_button({'name': 'clear_button_fun','widget': OrderLineClear,});

If you want to change it to clear all the cart the code will be,


var order = this.pos.get_order();

for (var lines in order.get_orderlines()){
    order.remove_orderline(order.get_orderlines());
