我正在尝试使用 ToastrJS 库显示 toast 消息。消息显示正常。问题是我没有找到传递错误消息的方法。我使用 connect-flash 来发送闪存消息，然后我想将消息传递给烤面包机。
我的EJS代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1">

<script src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/js/toastr.js"></script>
</head>
<body >
<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">Joobber</a>
</div>
<div class="collapse navbar-collapse" id="myNavbar">
<ul class="nav navbar-nav">
<li class=""><a href="#">Home</a></li>
<li><a href="#">Ver todas as vagas</a></li>
<li><a href="#">Vagas por categoria:</a></li>
</ul>
<ul class="nav navbar-nav navbar-right">
<li><a href="#"><span class="glyphicon glyphicon-user"></span> Ainda não está cadastrado?</a></li>
<li><a href="#"><span class="glyphicon glyphicon-log-in"></span> Logar</a></li>
</ul>
</div>
</div>
</nav>
<% if(success.length > 0){ %>
<script>
toastr.success('WANNA USE THE ERROR MESSAGE VARIABLE HERE!!!!')
</script>
<% } %>
<script type="text/javascript" src="js/aos.js">
</script>
<script type="text/javascript">
AOS.init({
offset: 200,
duration: 600,
easing: 'ease-in-sine',
delay: 100,
});
</script>
我还配置了 connect-flash 并使用一些本地变量来设置特定类型的消息
app.use(flash());
var sessionFlash = function(req, res, next) {
res.locals.currentUser = req.user;
res.locals.error = req.flash('error');
res.locals.success = req.flash('success');
next();
}
app.use(sessionFlash)
然后，我的路线：
const express = require('express')
const router = express.Router()
const indexControllers = require('../controllers/indexControllers')
router.get('/', indexControllers.HomePage)
router.get('/signup', indexControllers.Signup)
router.get('/test', (req, res)=>{
req.flash('success', 'user succesfulyl registered')
res.redirect('/')
})
module.exports = router;
如果你想用一句话显示带有错误和消息的toastr，那么使用toastr.info。如果没有，最好将成功消息和错误消息分开以获得更清晰的上下文。并像这样使用它：
<% if(success.length > 0){ %>
<script>
toastr.success(`${success[0]}`)
</script>
<% } %>
<% if(error.length > 0){ %>
<script>
toastr.error(`${error[0]}`)
</script>
<% } %>
我已经尝试过你的方法，但没有按预期工作
<script>
'<% if (adminCountError.length>0) { %>'
toastr.error("<%= adminCountError %>");
'<% } %>'
</script>
这对我有用
