Hi  All,

Below I attached my code ...

class pos_website_sale (http.Controller): 
@ http.route ([ '/ shop / clear_cart' ], auth = "public" , website = True ) 
def clear_cart ( self ): order = request.website.sale_get_order () 
if order:              for line in order.website_order_line: line.unlink ()

UPDATED CODE#############

$(document).ready(function (instance) 
{//debugger;$('.oe_website_sale').each(function () 
{    var oe_website_sale = this; 
 $(oe_website_sale).on("click", ".oe_cart #clear_cart_button", function ()
 {//    debugger;    var ajax = require('web.ajax');  
 ajax.jsonRpc("/shop/clear_cart", "call", {}).then(function(data){     
 location.reload(true);        })  
 return false;    })})})

I  got this error from the console...
