Is the jquery javascript file loaded before you call anything with it -> using the selector $? Please check with Chrome or Firefox+firebug if the jquery library is loaded correctly. Maybe the path could be not correct
jquery javascript 文件是否在您调用任何内容之前加载 -> 使用选择器 $？请检查 Chrome 或 Firefox+firebug 是否正确加载了 jquery 库。也许路径可能不正确
After that, try to place your code into:
之后，尝试将您的代码放入：
$(document).ready(function() {
// put all your jQuery goodness in here.
});
This will make sure that '// put all your jQuery goodness in here.' will be executed after jQuery has been loaded.
这将确保“// 将您所有的 jQuery 优点放在此处。” 将在 jQuery 加载后执行。
