Question

我试图将文本存储在变量var sendSpecialChat = hi; document.writeIn(sendSpecialChat.toUpperCase()); document.getElementById('print').innerHTML = "sendSpecialChat";大写中，但我无法找出它无法正常工作的原因。这实际上并不是我想要做的，但我简化了代码：

＆＃13;

<p id="print"></p>

＆＃13;

{{1}}

＆＃13;

虽然它不起作用。我的代码出了什么问题？

Answer 1

var sendSpecialChat = "hi"; document.getElementById('print').innerHTML = sendSpecialChat.toUpperCase();将为您提供字符串的大写版本。你的代码有一些问题，你需要在字符串周围使用引号（＆＃34;），而不是在变量名称周围。

＆＃13;

<p id="print"></p>

＆＃13;

'use strict';

/**
* Module dependencies
*/
var coursesPolicy = require('../policies/courses.server.policy'),
courses = require('../controllers/courses.server.controller');
var passport = require('passport');

 var isAuthenticated = function(req, res, next) {
 // if user is authenticated in the session, call the next() to call the next request handler
 // Passport adds this method to request object. A middleware is allowed to add properties to
 // request and response objects
 if (req.isAuthenticated())
     return next();
 // if the user is not authenticated then redirect the user to the login page
 res.redirect('/');
};

module.exports = function (app) {
// Courses collection routes
app.route('/api/courses').all(coursesPolicy.isAllowed)
.get(courses.list)
.post(courses.create);

// Single course routes
app.route('/api/courses/:courseId', isAuthenticated).all(coursesPolicy.isAllowed)
.get(courses.read)
.put(courses.update)
.delete(courses.delete);

// Finish by binding the course middleware
app.param('courseId', courses.courseByID);
};
