问候，如何使用ajax和jquery下载一些页面内容：我正在做类似的事情（一个脚本中有2个版本）：

$("p").click(function() {

    $('#result').load('http://google.com');

            $.ajax({
                url='www.google.com',
                success: function(data) {
                    $("result").html(data);
                    alert('Load was performed.');
                    var url = 'www.wp.pl';
                    $('div#result').load(url);
                    //var content = $.load(url);
                    //alert(content);
                    //$("#result").html("test");
                }
            });

You could use YQL to proxy your call:

您可以使用YQL代理您的通话：

$.ajax({
  url:"http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20html%20where%20url%3D'http://www.google.com'&format=xml&callback=callback",
  type: 'GET',
  dataType: 'jsonp'
});

  function callback(data){
    $('#result').html(data.results[0]);
  }

Due to restrictions you cannot download the contents of a web page using AJAX that is not hosted on the same domain as the domain hosting this script. Also you have a syntax error in your .ajax function call. It should look like this:

由于限制，您无法使用与托管此脚本的域不在同一域中托管的AJAX下载网页内容。您的.ajax函数调用中也存在语法错误。它应该如下所示：

$.ajax({
    url: 'http://yourdomain.com/page1.htm',
    success: function(data) {
        $("result").html(data);
        alert('Load was performed.');
        var url = 'http://yourdomain.com/page2.htm';
        $('div#result').load(url);
    }
});

While it is not possible to directly query a host that is external to the current domain from Javascript, you could use a proxy script to retrieve the desired data.

虽然无法从Javascript直接查询当前域外部的主机，但您可以使用代理脚本来检索所需的数据。

使用jQuery查询跨域AJAX：http：//jquery-howto.blogspot.com/2009/04/cross-domain-ajax-querying-with-jquery.html

You could also make use of the flXHR script, which can be dropped into many Javascript libraries (including jQuery).

您还可以使用flXHR脚本，该脚本可以放入许多Javascript库（包括jQuery）中。

flXHR: http://flxhr.flensed.com/

flXHR：http：//flxhr.flensed.com/

You could also simply call a PHP/ASP/RUby page that in turn does the outside calling for you and presents the information in a way that you need.

你也可以简单地调用一个PHP / ASP / RUby页面来反过来为你做外部调用，并以你需要的方式呈现信息。

1.  PAGE --> PHP --> External web
        (Ajax)

2.  PAGE <-- PHP <-- External web
      (callback)

You need to use something called JSONP to go across domain. Seider has psoted more details on how to do this with jQuery.

您需要使用名为JSONP的内容来跨域。 Seider提供了有关如何使用jQuery执行此操作的更多详细信息。
