上午使用codeigniter，我正在購物車。使用ajax jquery選擇項目到購物車後。在這裏，項目菜單和購物車表將並排顯示。如何使用codeigniter中的ajax jquery將頁面重定向到另一個頁面？
現在，我的任務是通過點擊按鈕完成購物車項目到另一個表格。現在的問題是點擊按鈕，我需要複製，並在一個時間，我需要路由到另一個頁面..在這裏，我可以複製購物車項目到另一個表，但我不能重定向到another.for這個我用jqueryajax。
現在我需要的路線這在視圖文件夾users/basket.php

注意：在product_controller.php我編碼的按鈕將購物車項目複製到另一個表格。在按鈕單擊事件我在jQuery的AJAX寫了下面
的jQuery的Ajax：
<script>
$(document).ready(function(){
$('.add_cart').click(function(){
var product_id=$(this).data("productid");
var product_name=$(this).data("productname");
var product_price=$(this).data("price");
var quantity=$('#' + product_id).val();
if(quantity != '' && quantity >0)
{
$.ajax({
url:"<?php echo base_url();?>products/add",
method:"POST",
data:{product_id:product_id,product_name:product_name,product_price:product_price ,quantity :quantity},
success:function(data)
{
alert("Product Added into cart");
$('#cart_details').html(data);
$('#' + product_id).val('');
}
});
}
else
{
alert("Please Enter Quantity");
}
});
$('#cart_details').load("<?php echo base_url();?>products/load");
$(document).on('click','.remove_inventory',function(){
var row_id = $(this).attr("id");
if(confirm("Are you sure you want to delete item")){
$.ajax({
url:"<?php echo base_url();?>users/remove",
method:"POST",
data:{row_id:row_id},
success:function(data)
{
alert("Product remove fromm cart");
$('#cart_details').html(data);
}
});
}else{
return false;
}
});
$(document).on('click','#clear_cart',function(){
if(confirm("Are you sure you want to delete item"))
{
$.ajax({
url:"<?php echo base_url();?>products/clear",
success:function(data)
{
alert("Are you sure you want clear cart?");
$('#cart_details').html(data);
}
});
}
else{
return false;
}
});
$(document).on('click','.basket',function(){
if(confirm("Are you sure you want to delete item"))
{
$.ajax({
url:"<?php echo base_url();?>products/basket",
method:"POST",
success:function(data)
{
alert("Are you sure?");
window.location="users/basket";
}
});
}
else{
return false;
}
});
});
</script>
----------
你應該經常檢查你的ajax請求是否成功/失敗，從你的控制器返回一個布爾值並檢查。例如：if（data.status）{window.location.href =「your_url_here」} – Shan
