How does Empire ECMS implement AJAX without refreshing and adding to the shopping cart

Empire ECMS implements AJAX without refreshing and adding to shopping cart The main steps of the shopping cart method are as follows:

1. Modify the mall content template and add the following code to the head:

<script type="text/javascript" src="[!--news.url--]skin/default/js/jquery.js"></script>
<script type="text/javascript" src="[!--news.url--]skin/default/js/addBuyCar.js"></script>
<script type="text/javascript">
    var newsurl=&#39;<?=$public_r[newsurl]?>&#39;;
</script>

2. Modify the mall Content template, add the shopping cart part and modify it to the following code:

<a href="#ecms" onclick="AddProduct([!--classid--],[!--id--]);">加入购物车</a>

3. As for the jquery file, it is compatible with versions 1.3 and 1.4 and can be downloaded by yourself. The source code of the file addBuyCar.js is as follows:

function AddProduct(classid, id) {
    $.ajax({
        type: "post",
        url: newsurl + "e/template/ShopSys/addBuyCar.php",
        data: "classid=" + classid + "&id=" + id,
        dataType: "json",
        success: function (json) {
            alert(json.msg);
        }
    })
}

Fourth, add the handler e/template/ShopSys/addBuyCar.php, the source code is as follows:

<?php 
 require("../../class/connect.php");
 require("../../class/db_sql.php");
 require("../../data/dbcache/class.php");
 require("../../class/ShopSysFun.php");
 $link=db_connect();
 $empire=new mysqlquery();
</p> <p>//$_POST $classid=(int)$_POST[&#39;classid&#39;];
 $id=(int)$_POST[&#39;id&#39;];
</p> <p>//add function function json_AddBuycar($classid, $id) {
    global $class_r, $empire, $dbtbpre, $public_r;
    $classid=(int)$classid;
    $id=(int)$id;
    if(empty($classid)||empty($id)||empty($class_r[$classid][tbname])) {
        return json_encode(array(&#39;msgid&#39;=>1, &#39;msg&#39;=>&#39;此商品不存在&#39;));
    }
    //验证产品是否存在 $num=$empire->gettotal("select count(*) as total from {$dbtbpre}ecms_".$class_r[$classid][tbname]." where classid=&#39;$classid&#39; and id=&#39;$id&#39; limit 1");
    if(!$num) {
        return json_encode(array(&#39;msgid&#39;=>1, &#39;msg&#39;=>&#39;此商品不存在&#39;));
    }
    $record="!";
    $field="|";
    $productid=$classid.",".$id;
    $buycar=getcvar(&#39;mybuycar&#39;);
    //重复 if(strstr($buycar, "|".$productid."|")) {
        $pr=explode("|".$productid."|", $buycar);
        $pr1=explode("!", $pr[1]);
        $oldbuycar="|".$productid."|".$pr1[0]."!";
        //数量 $pr1[0]=ReturnBuycarProductNum($pr1[0]);
        if(empty($pr1[0])) {
            $pr1[0]=1;
        }
        $newnum=$pr1[0]+1;
        $newbuycar="|".$productid."|".$newnum."!";
        $buycar=str_replace($oldbuycar, $newbuycar, $buycar);
    }
    else {
        //只存放一个 if($public_r[&#39;buycarnum&#39;]==1) {
            $buycar=&#39;&#39;;
        }
        $buycar.="|".$productid."|1!";
    }
    $re=SetBuycar($buycar);
    if($re) {
        return json_encode(array(&#39;msgid&#39;=>2, &#39;msg&#39;=>&#39;商品加入购物车成功&#39;));
    }
}
echo json_AddBuycar($classid, $id);
 db_close();
 $empire=null;
 ?>
