然而，它似乎没有反应，我可能错过了这一点。以下是my.aspx页面中的代码/脚本：

$(document).ready(function () {
    // External ASPX Page calling   
    $("#btn_Submit").click(loadDynamic);
});

function loadDynamic() {

    $("#dynamicResults").load("ResultsView.aspx", 
        {name: $("#cbox_User").val() },  
        function (content) {   
           $(this).hide().fadeIn("slow");
                return false;
        });

加载页面片段。加载（）方法不同于$.get（），它允许我们指定遥控器的一部分要插入的文档。这是用一种特殊的语法为 url参数。如果一个或多个空间字符串中包含字符，字符串的以下部分假设第一个空间为确定要加载的内容

$('#result').load('ajax/test.html #container');

当这个方法执行时，它检索的内容 ajax/test.html，但jQuery会解析返回的文档以查找 ID为container的元素。这元素及其内容是插入到具有ID的元素中结果如何，剩下的检索到的文档将被丢弃

jQuery使用浏览器的.innerHTML 属性来分析检索到的文档并将其插入到当前文件。在这个过程中,，浏览器通常从中过滤元素该文件包括：，或元素。因此 .load（）检索到的元素可能不存在与文档完全相同直接由浏览器

$("#cbox_User").val()

$("#<%=cbox_User.ClientID%.").val()

但是，由于它是一个服务器端控件，因此需要获得如下值：

$("#你能接受其他一些问题的答案吗？谢谢！这是绿色的复选标记吗？是的。你可以点击答案左边上下箭头下方的透明复选标记，将答案标记为已接受。不确定我做错了什么。我的脚本放错地方了吗？我使用母版页和协议ion，这两者中的任何一个会影响到这个吗？修复了这个问题，必须在母版页中注册jQuery。
