Question

我正在尝试从会话购物车中删除产品。我发送请求从Ajax到点击事件没有任何反应。这是我的代码。我没有得到任何回复，像按钮根本没有什么工作。我按下按钮以从会话数据中删除id并删除产品div。

function removeFromBasket(item) {
        var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                alert('item removed')
            }
            else if(xmlhttp.status == 400) {
                alert("request error 400");
            }
            else{
                alert("something went wrong");
            }
        };
    xmlhttp.open("GET","cart.php?remove="+item,true);
    xmlhttp.send();
}

cart.php

    <?php
    require "cfg.php";
    if(isset($_GET['remove'])){
        $id = $_GET['remove'];
    $items = $_SESSION["cart"];
    if(($key = array_search($id, $items)) !== false) {
        unset($items[$key]);
        $ses = $_SESSION["cart"] = array_values($items);
    }
    print_r($ses);
    die();


    }
    ?>

    <?php

    $cartItems = array_keys($cart);
    $q = "select * from items where id in (".implode(",",$cartItems).")";
    $db = Database::getInstance();
    $res = $db->_db->query($q);
    foreach($res as $item){
      ?>
      <form method="post" action="" class='.remove'>
      <div style='border:1px solid blue;padding:4px;'>
        <?=$item['name']?> (<?=$cart[$item['id']]?>)
    <input class='glyphicon glyphicon-remove' onclick='removeFromBasket(<?= $cart[$item['id']] ?>)' name='submit' type='button' value='Remove' >
      </div>

      <?php
    }
    ?>

Ajax不要激活php代码
