无法从ajax响应中获取body元素

Question

响应是HTML文档(来自链接href的请求)

 var data = $(response).find('body').html();
 alert(data);  

 // I get a alert with nothing...

完整代码:

     $.ajax({
       url: $(this).attr('href'),
       type: 'GET',      
       success: function(response){
         var data = $(response).find('body').html();
         alert(data);  
        }
     });

Answer 1

试试这种方式:

var $dom = $(document.createElement("html"));
$dom[0].innerHTML = response;

var $body = $dom.find("body");

Answer 2

使用这个棘手的代码;)

   /*this will get the body content and head by replacing them with div before placing them inside the jQuery factory witch will avoid all bugs, i used this while creating the ajaxit jquery plugin :) */
$.ajax({
                type: "GET",
                url: $(this).attr('href'),
                async:true,
                error:function (event, request, options, error) {
                    if (ajaxItMain.onError){
                        ajaxItMain.onError(event,request,options,error);
                    }
                },
                success:  function (data) {
                    // ----------------- < data >
                    // clearing CDATA
                    data=data.replace(/\<\!\[CDATA\[\/\/\>\<\!\-\-/gi,'');
                    data=data.replace(/\/\/\-\-\>\<\!\]\]\>/gi,'');

                    // extracting the the head and body tags
                    var dataHead = data.match(/<\s*head.*>[\s\S]*<\s*\/head\s*>/ig).join("");
                    var dataBody = data.match(/<\s*body.*>[\s\S]*<\s*\/body\s*>/ig).join("");
                    var dataTitle = data.match(/<\s*title.*>[\s\S]*<\s*\/title\s*>/ig).join("");

                    dataHead  = dataHead.replace(/<\s*head/gi,"<div");
                    dataHead  = dataHead.replace(/<\s*\/head/gi,"</div");

                    dataBody  = dataBody.replace(/<\s*body/gi,"<div");
                    dataBody  = dataBody.replace(/<\s*\/body/gi,"</div");

                    dataTitle = dataTitle.replace(/<\s*title/gi,"<div");
                    dataTitle = dataTitle.replace(/<\s*\/title/gi,"</div");


                    // comments
                    var commentPattern = /\<\!\-\-([\s\S]*?)\-\-\>/ig;

                    // get head comment tags
                    var headComments = dataHead.match(commentPattern);

                    // get body comment tags
                    var bodyComments = dataBody.match(commentPattern);

                    // head - body - title content
                    var $dataHead    = $(dataHead);
                    var $dataTitle   = $(dataTitle);
                    var $dataBody    = $(dataBody);
                }
            });
        }
