Question

我的脚本我想从ajax.php中读取并显示它们，并在我想要从数据库中获取的ajax.php中。我的问题是从数据库中获取不起作用！

echo
               '<?php while ($row = mysqli_fetch_array($products)):?>
                <div class="item-in-cart clearfix">
                        <div class="image">
                            <img src="images/<?php echo $row['id'] ?>" width="124" height="124" alt="cart item" />
                        </div>
                        <div class="desc">
                            <strong>
                                <a href="product.html">s</a>
                            </strong>
                            <span class="light-clr qty">
                                <a href="#" class="icon-remove-sign" title="Remove Item"></a>
                            </span>
                        </div>
                        <div class="price">
                            <strong></strong>
                        </div>
                </div>';
                <?php endwhile;?>


    $(document).ready(function(){
        $(".addCart").click(function(){
            var id = $(this).val();
            $.ajax({
                type:'post',
                url:'ajax.php',
                data :{
                    id : 'id',
                },
                success : function (response) {
                $('#cart').html(response);
                }
            });

        });
    });

在AJAX的返回循环中，将所有结果放在变量中的一个连接字符串中。然后回显该变量作为ajax中的返回。

确保标签上有ID“cart”

ajax.php

let processoperatorchange2 t2s2 proc2 op op2=
  let rec poc2 p = match p with
    | Zero ->  "0"
    | Pproc (x) -> String.lowercase x
    | In(chan, var, _, p, _) ->  chan^"("^var^")"^op^(poc2 p); chan^"("^var^")"^op2^(poc2 p)
  in poc2 proc2

然后将推送HTML数据块并将其插入购物车ID标签内，但也可以在调用ajax时，或者在插入之前，先清空购物车ID

<?php
$return = "";
while($row = mysqli_fetch_assoc($products)):
$id = $row['id'];
$return .= "<div class='item-in-cart clearfix'>
    <div class='image'>
        <img src='images/$id' width='124' height='124' alt='cart item' />
    </div>
    <div class='desc'>
        <strong>
            <a href='product.html'>s</a>
        </strong>
        <span class='light-clr qty'>
            <a href='#' class='icon-remove-sign' title='Remove Item'></a>
        </span>
    </div>
    <div class='price'>
        <strong></strong>
    </div>
</div>";
endwhile;

echo $return;
?>

从ajax中的数据库中获取
