Express+jade: local variable not available in view

阅读更多关于 Express+jade: local variable not available in view

问题 I ran into a very basic problem but I can't seem to find the answer to it. I am working with node.js , express and I am just trying to pass a local variable into the view like this: app.get('/', function(req, res){ res.render("index", {locals: { title: "Blog", } }); }); My index view is equally simple: h1= title But for some reason, I keep getting this error as if the local variable is never passed: 500 ReferenceError: /home/spartan/Node_Projects/test/views/index.jade:1 > 1| h1= title 2|

How to generate a pure JavaScript file with Jade

阅读更多关于 How to generate a pure JavaScript file with Jade

I know that Jade is for producing HTML instead of JavaScript, but for a project I'm working, it would be great, and a huge time saver, if I could do this without adding a pipe in every line: | (function(){ | //Some JavaScript Code | var foo="#{bar}"; | console.log("This a JavaScript file generated with Jade"); | })() The idea is to use the output of this template as the source of a regular JavaScript include like this: <script type="application/javascript" src="foo.generated.js"></script> So doing something like this: script(type="application/javascript"). (function(){ //Some JavaScript Code

问题 I am very new to Node and still in the beginning stages of understanding its use and power. I apologize if this question comes across as very simple or naive - I did due research before asking. In my express js application, I sent a GET request to a remote API and properly received the appropriate JSON data in return. I then passed it to my views (Jade) and currently have the ability the print the JSON in string form. That all works properly. The JSON data I have is a group of people/members

Using javascript code in Jade views - if(variable) shows undefined instead of passing

阅读更多关于 Using javascript code in Jade views - if(variable) shows undefined instead of passing

So this is a recurring issue I have and haven't found another example on SO so here goes: When rendering Jade templates I get 'variableName' undefined even when using -if(variableName) in the template. Example (I'm using this as a partial for 'info' flash messages): -if(info) - if(info.length){ ul -info.forEach(function(info){ li= info -}) -} This returns 'info' is not defined instead of not rendering anything when there isn't a flash/info message. Does anyone know what I'm doing wrong? I'm aware of the typeof(variable) != 'undefined option as mentioned. If I wanted to do something like -if

I've been creating an app with Passport, Express 4 and Jade. I would like to show the user a navbar that changes when they log in.

I get the user like this: router.get("/profile",

Expanding an object to set attributes in Jade

阅读更多关于 Expanding an object to set attributes in Jade

I would like to be able to pass in an object with key/value pairs that represent attributes for an element. Is this possible with Jade? Any solution that allows me to pass an attributes collection into my template would be sufficient, but the ability to mix explicitly declared attributes with attributes extracted from an object (as below) would be ideal. The following syntax does not work, it is just an example of what I'd like to do. For example, if I passed this: { name:'username', value:'bob', attributes: { maxlength: 16 } } To this template: input(name=name, value=value, attributes) The
