ajax无法在购物车中一键工作

ajax not working onclick in shopping cart

本文关键字：一键 工作 购物车 ajax      更新时间：2024-04-26

我正在使用免费下载的"Ustora"模板（电子商务的html主题）。同样，我正在处理单个产品页面中的"添加到购物车"按钮。点击后，它应该会启动一个ajax函数，将产品数据插入数据库中的购物车表中。但这个不起作用。

我正在用这个来学习制作电子商务网站。请尽快提供帮助，下面是我的代码。

单一产品页面.php 

             <?php 
                $row = mysql_fetch_row(mysql_query("SELECT * FROM `products` where pid='".$_GET['proid']."' "));
                echo '<div class="row">
                    <div class="col-sm-6">
                        <div class="product-images">
                            <div class="product-main-img">
                                <img src="'.$row[5].'" alt="'.$row[2].'">
                            </div>
                            <div class="product-gallery">
                                <img src="'.$row[5].'" alt="'.$row[2].'">
                                <img src="'.$row[5].'" alt="'.$row[2].'">
                                <img src="'.$row[5].'" alt="'.$row[2].'">
                            </div>
                        </div>
                    </div>
                    <div class="col-sm-6">
                        <div class="product-inner">

我只想在"添加到购物车"按钮上启动addtocart（）功能，点击后想在购物车中插入数据。

提前感谢

我认为问题出在将数据发送到新页面的数据中

function addtocart(pid,name,price,buid)
    {
    alert("addToCart function working");
    var pid = pid;
    var pname = name;
    var pprice = price;
    var pqty = document.getElementById("qty").value; //$(#qty).val();
    var buid = buid;
    //var cstid = $(#).val();
    $.ajax({
            type:"POST",
            url:"http://localhost/phpsales/insert-cart.php",
            data:{pid,pname,pprice,pqty,buid},//here is the problem 
            data:{pid:pid,pname:pname,pprice:pprice,pqty:pqty,buid:build},//this must be like this
            cache:false,
            success:alert("Product Added Successfully")
            //error:function fail(){alert("Some technical error occured dufine product add to cart. Please try after some time.");}
        });
    }

我认为您需要在调用addToCard()函数的参数周围加引号，如下所示：onclick="addtocart(/''.$row[1].'/',/''.$row[2]./'',/''.$row[3].'/',/''.$buid.'/');"
