jQuery没有找到任何元素.alert($("#testbutton").length);每次显示0.
难道我做错了什么？
我的JS/jQuery代码:
(function ($) {
alert($("#testbutton").length);
}) (jQuery);
我的HTML:
<html>
<body>
<div id="header">
<div class="button" id="testbutton">Test</div>
</div>
</body>
</html>
我想使用MEAN.io堆栈.我做了必要的初始化.创建了文件夹,安装了npm,获得了库.
现在在server/config/express.js我有
assetmanager = require('assetmanager'),
和
// Import your asset file
var assets = require('./assets.json');
assetmanager.init({ // this is line 75
js: assets.js,
css: assets.css,
debug: (process.env.NODE_ENV !== 'production'),
webroot: 'public/public'
});
这给了我这个错误:
server/config/express.js:75
assetmanager.init({
^
