Question

这是我的jquery：

$.ajax({
url: hash,
    success: function(data){
        var thePage = $(data);
        alert(data);
        $('#slider_menu').html($('div#menu_bg', thePage).html());
    }
});

警报（数据）返回：

但#menu_bg div不会返回其内容！：（

对于嵌入到文档中的任何div，这个工作（例如，这将有效），但我对所请求页面的内容没有任何发言权。

为什么这不起作用的任何想法？或者如何让它发挥作用？

谢谢

Answer 1

你能试试吗？

   $.ajax({
    url: hash,
        success: function(data){
            $('#slider_menu').html($(data).filter('div#menu_bg').html());
        }
    });

希望这有帮助。

Answer 2

如何找到div#wrapper的父级？

Answer 3

您可以尝试从body代码开始。

$("body").next()

next（）为您提供即时标记。

Answer 4

必须更改返回的代码......没有答案 - 它必须是一个bug或类似的。

Answer 5

尝试

$('#slider_menu').html($(data).find('div#menu_bg').html());

干杯！

在ajax请求之后无法从jquery对象获取div内容
