    ( 
        "JQueryPage.aspx", function(html) { 
            var page = $(html);
            var div = $('#div1', page);
        }  
    ); 

</script>

you can also look into the $.load function

你也可以查看$ .load函数

Jsut wrap the data in a call to jquery and you can use it like you would normally:

Jsut在调用jquery时包装数据,你可以像平常一样使用它:

$.get
    (
        "JQueryPage.aspx",
        function(data) {
            var dataDom = $(data);
            $(someSelector, dataDom).each(function(){
                alert($(this).html());
            });
          } 
    );

If the html markup of JQueryPage.aspx is valid xml, you can use dom parser to get the required div.

如果JQueryPage.aspx的html标记是有效的xml,则可以使用dom解析器来获取所需的div。

It depends - if all you want is to add the retrieved html to the existing DOM using a call to document.appendChild, yes. But if you need to parse and read values from the retrieved data, no, this is not. Pass data as a JSON string or xml.

这取决于 - 如果你想要的是使用对document.appendChild的调用将检索到的html添加到现有DOM中,是的。但是,如果您需要从检索到的数据中解析和读取值,不,这不是。将数据作为JSON字符串或xml传递。
