页面爬虫(获取其他页面HTML)加载到自己页面示例

//前台

<div id="showIframe"></div>

$(document).ready(function() {

var url = "@Url.Action("GetPageHtml","Catalog")";

$.ajax({

url: url,

type: "POST",

dataType:"json",

data: { url: "http://www.baidu.com" },

error: function () {

alert("bbb");

},

success: function (data) {

$("#showIframe").append(data);

//$("#showIframe div").hide();

//$("#showIframe>#container").show();

//$("#showIframe>#container>#content").show();

//$("#showIframe>#container>#content>.cmsPage").show();

}

});

});

//后台

//爬虫本质，发送URL请求，返回整个页面HTML
