Question

很抱歉提出这个问题，因为在 Microsoft JScript运行时错误：'$'未定义错误之前，这是多次询问。我的最后一个项目是工作jquery，当我将我的代码/ .js复制粘贴到新项目时，我收到了这个错误。

我知道当.js不是head标签上的引用时会发生此错误，但我确信我的主页上有我的引用我的.js。

当我尝试运行开发人员工具（F12）并检查脚本是否已加载时，此错误显示

<html>
<head>
    <title>The resource cannot be found.</title>
    <style>
        body { font-family: "Verdana"; font-weight: normal; font-size: .7em; color: black; }
        p { font-family: "Verdana"; font-weight: normal; color: black; margin-top: -5px; }
        b { font-family: "Verdana"; font-weight: bold; color: black; margin-top: -5px; }
        H1 { font-family: "Verdana"; font-weight: normal; font-size: 18pt; color: red; }
        H2 { font-family: "Verdana"; font-weight: normal; font-size: 14pt; color: maroon; }
        pre { font-family: "Lucida Console"; font-size: .9em; }
        .marker { font-weight: bold; color: black; text-decoration: none; }
        .version { color: gray; }
        .error { margin-bottom: 10px; }
        .expandable { text-decoration: underline; font-weight: bold; color: navy; cursor: hand; }
    </style>
</head>

但是，当我使用工作jquery运行我之前的项目时（相同的.js版本具有相同的文件夹结构）这是我点击开发人员工具时显示的内容

/*!
 * jQuery JavaScript Library v1.7.2
 */

(function( window, undefined ) {

// Use the correct document accordingly with window argument (sandbox)
var document = window.document,
    navigator = window.navigator,
    location = window.location;
var jQuery = (function() {
// Define a local copy of jQuery
var jQuery = function( selector, context ) {
      // The jQuery object is actually just the init constructor 'enhanced'
      return new jQuery.fn.init( selector, context, rootjQuery );
    },
    //Etc etc.............

见下我的标记代码：

    </script>
</head>

任何形式的帮助都将受到赞赏。

请确保脚本文件的路径正确无误。因为../Script/jquery-1.4.1.min.js表示您的脚本文件存在于层次结构之外的2个级别而不是页面。

例如。

首先让我们假设项目结构
- 溶液 - ＆GT;项目 - ＆GT;脚本
- 溶液 - ＆GT;项目 - ＆GT; Default.aspx的
比您的页面和脚本文件夹在层次结构中处于同一级别。所以路径一定是的 “脚本/ jQuery的1.7.2.min.js”

现在假设这个项目结构

溶液 - ＆GT;项目 - ＆GT;脚本

溶液 - ＆GT;项目 - ＆GT;默认 - ＆GT; Default.aspx的

因为这里脚本文件夹在层次结构中是一级的。所以路径要添加脚本的Default.aspx必须是“./ Script / jquery-1.7.2.min.js”

因此，请注意访问项目文件的路径。
