我想用jade渲染一個頁面。在我的路線文件我有這樣的:爲什麼我的玉變量未定義?
exports.start = function(req, res){
res.render('start', {
title: 'Special you!',
locals: {
percent: 0
}
});
};
在start.jade文件我想用這樣的百分比變量:
.progress.progress-success
.bar(style='width: #{locals.percent}')
我也包含在本start.jade代碼,調試的目的:
each item in locals
p= item
輸出是這樣的:
[object Object]
Special you!
function locals(obj){ for (var key in obj) locals[key] = obj[key]; return obj; }
false
C:\Users\Alexandru\Documents\GitHub\yolo-adventure\views\start.jade
並且locals.percent的值未定義。
完整start.jade文件是:
extends layout
block custom-style
link(rel='stylesheet', href='/stylesheets/main-style.css')
block content
h1 Start from here
each item in locals
p= item
.progress.progress-success
.bar(style='width: #{locals.percent}')
頁面的源代碼是這樣的:
<!DOCTYPE html>
<html>
<head>
<title>Special you!</title>
<link rel="stylesheet" href="/stylesheets/bootstrap.css">
<link rel="shortcut icon" href="/images/favicon.png">
<link rel="stylesheet" href="/stylesheets/main-style.css">
</head>
<body>
<h1>Start from here</h1>
<p>[object Object]</p>
<p>Special you!</p>
<p>function locals(obj){
for (var key in obj) locals[key] = obj[key];
return obj;
}
</p>
<p>false</p>
<p>C:\Users\Alexandru\Documents\GitHub\yolo-adventure\views\start.jade</p>
<div class="progress progress-success">
<div style="width: undefined" class="bar"></div>
</div>
</body>
</html>
這究竟是爲什麼?
它說「undefined」? '特別你!'從哪裏來? – Amberlamps
哦..我將標題值從Special改爲!到你好,當我創建這篇文章,但在我的代碼是「特別你!」 –
