我在这里和互联网上搜索了几乎所有东西，但我无法让这段代码工作。当用户单击 php 生成的链接加载另一个页面并且它有一个表单等时，我试图打开对话框。单击某个链接，它将生成一个弹出窗口，将其关闭，然后单击其他一些或相同的链接，它不会打开弹出窗口。

这就是我的 html 的生成方式

echo '<div class=product_name><a href="edit_order.php?order_number='.$order_numbers.'&product_id='.$row['id'].'&quantity='.$row['quantity'].'&sale_price='.$row['sale_price'].'&id='.$row['order_product_id'].'" style="text-decoration: none" title="View Details"><h3>'.$row['productname'].'</h3></div>
    <div class=quantity><h3>'.$row['quantity'].'</h3></div>
    <div class=sale_price><h3>'.$row['sale_price'].'</h3></div></a>';

问题是在带有参数dialog的关闭回调中调用方法。destroy你有：

close: function(event, ui) {
    alert("ali");
    $(this).dialog('destroy');
}

在你内部调用$(this).dialog('destroy');这就是为什么它只工作一次。

那是对我有用的代码，尝试用它代替你的代码：

<script>
$(function() {
    $('.dialog').dialog({
        modal: true,
        height: 200,
        autoOpen: false,
        closeOnEscape: true,
        hide: "slide",
        open: function(event, ui) {
            var url = $('.header a').attr('href');
            //alert(url);
            $(".dialog").load(url); //use the previously saved id
        }
    });

    $('.header a').bind("click", function(event) {
        event.preventDefault();
        $('.dialog').dialog('open');
        //$('#dialog').load(url);
    });
}); 
</script>
