I have an EJS file called 'test.ejs', which contains:
<p>This is a test statement</p>
Then, I have another file called 'index.ejs' which is in the same folder as the other EJS file. Index.ejs contains:
<%- include ("test") %>
<p>Hello world</p>
However, when I load the page, I do not get any output. Instead, the page just loads endlessly.
My routes in Express are being handled properly and my controllers are working too. All this is tested.
Also, can someone refer me to good EJS documentation?
Try this:
<% include ./test %>
<p>Hello world</p>
try: <% include /pathname/test %>
Documentation is sparse but the official one works

how can i dynamically delete widgets from a job(rb) in Dashing?
I am building the dashboard dynamically by sending a data to the erb file:
<div class="gridster">
<ul>
<% settings.servers.each do |data| %>
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
<div data-id="<%=data['webHost']%>" data-title="<%=data['name']%>" data-version="<%=data['Version']%>" >
</li>
<% end %>
</div>
Yes. I wrote a simple example job that can do just that here:
http://www.mapledyne.com/ideas/2015/6/30/delete-a-dashing-dashboard-widget
You basically just want to manipulate the Sinatra::Application.settings.history variable, but the code in that link should get you most of the way to where you want to be.
Or skip the post and go right to the gist file:
https://gist.github.com/mapledyne/6fb671c17c3f865309f3#file-delete-widget-rb
You can also generate parts of the erb dynamically if you don't know the widgets in the first place (more complicated), but it starts with the same - leveraging that same history variable.
As a real beginner in EJS, I have two charts in my html page, so I want to use my partial twice:
<% include partials/spider-chart.ejs %>
But I need to pass some parameters inside the ejs to differentiate between graphs.
What is the best way?
#Naeem Shaikh solution works.
Though include also gives you more intuitive way of including a partial template and also passing context variables to that as found in documention section of ejs.
<ul>
<% users.forEach(function(user){ %>
<%- include('user/show', {user: user}); %>
<% }); %>
</ul>
I think you want to render two different charts using same partial ejs template, just by providing different data(within the main ejs file).
You can just define a variable, which will be assigned to the data, which the first chart will use, than include the chart.ejs file, again change the data, and include the partial ejs file(chart.ejs) again, so now you have two files which can use same variable(data), but can plot different chart based on value assigned to data.
For Example:
<% var data= 'data to be used by first chart(parameter)'; %>
<% include partials/spider-chart.ejs %>
// re-initializing data for second chart
<% data= 'data to be used by second chart(parameter)'; %>
<% include partials/spider-chart.ejs %>
where your spider-chart.ejs file could be something which will use data
spider-chart.ejs
<li>
<%= data %> // just an example
</li>
here, as you use data, the data variable accessed by both charts will be different because you are reassigning values for data before every chart.
You can pass single as well as multiple data here is how to do it
In render funtions
We can pass multiple data as an object like this
app.get("/account", function(req, res) {
res.render("account", {
name: 'Jon Snow',
age: 35
});
});
And then can access the data inside account using ejs simple template tags like this
<h2> hello <%= name %> </h2>
<p> your age is <%= age %> </p>
In Partial views
Pass the data like this
<%- include('partials/logout', {name='triyon'}) %>
And access it like we did above
<h2> logged out <%= name %> </h2>
This is the best workaround by just passing the view file name as a context while rendering the base ejs file.
/base.ejs:
<html>
<%- include(content) %>
</html>
/extra.ejs:
<div> some content which is to be added in base ejs file </div>
/controller.js:
res.render('base', { content: 'extra' })
I'm using EJS as a part of my front-end dev stack.
For example my normal index.ejs looks like that:
<%- include parts/header.ejs %>
<%- include parts/navigation.ejs %>
<!-- HTML content: divs, spans, etc. -->
<%- include parts/footer.ejs %>
What I want is to pass somehow a variable with the include <%- include parts/footer.ejs?variable=value %> and want to read it in the included file, to conditionally show/hide some parts of the content.
I can't find the way to do it. Is it possible with EJS?
Two ways to do this:
Dumb Way
This way is compatible with EJS 1.0, and has the advantage of being compile-time.
Just declare the variables right before includeing.
Example:
included.ejs:
<p><%= variable %></p>
main.ejs:
<% var variable = 'hola' %>
<% include included %>
Smart Way
This method is only available with EJS 2.0 or newer, but might be marginally slower (or a lot slower if caching is not enabled) than the last method:
included.ejs:
<p><%= variable %></p>
main.ejs:
<%- include('included', {variable: 'hola'}) %>
Getting through Michael Hartl's tutorial great; I've encountered a few snags along the way but nonetheless, it's working out better than I expected.
My question, is regarding the partial file. In the tutorial if I have read correctly, chapter 5- it advises to edit the 'application.html.erb' file with...
'<!DOCTYPE html>
<html>
<head>
<title><%= full_title(yield(:title)) %></title>
<%= stylesheet_link_tag "application", media: "all",
"data-turbolinks-track" => true %>
<%= javascript_include_tag "application", "data-turbolinks-track" => true %>
<%= csrf_meta_tags %>
<%= render 'layouts/shim' %>
</head>
<body>
<%= render 'layouts/header' %>
<div class="container">
<%= yield %>
</div>
</body>
</html>'
The tutorial then says if this line worked I should find a file called 'app/views/layouts/_shim.html.erb' and I cannot find it, thus, it was not automatically created, further not allowing me to pull up the referring static page in my browser (which may or may not be related).
Thanks in advance.
Of course, to get the partial to work, we have to fill it with some content; in the case of the shim partial, this is just the three lines of shim code from Listing 5.1; the result appears in Listing 5.10.
So yes. You have to create partial file by yourself and fill it with proper content. In case you code editor doesn't support partial extraction.
For example:
Using rails.vim plugin for VIM there is the possibility to extract selected lines into partial by using Rextract <partial_name> command. Which creates new file, moves selected lines into it and replace selected lines from source file with <%= render :partial => '<partial_name>' %>
I have been pretty much in love with knockout lately, and here is my first copy-and-paste source snip :rolleyes:. Without luck, I fail to make it work on the local host server, although I already set up the knockout.js in the same directory of the file.php. I hope someone could help.
<script type="text/javascript" src="knockout210.js"></script>
<script type="text/javascript">
var ViewModel=function(first, last)
{
this.firstName=ko.observable(first);
this.lastName=ko.observable(last);
this.fullName=ko.computed(function()
{
return this.firstName()+" "+this.lastName();
},this);
}
ko.applyBindings(new ViewModel("Planet","Earth"));
</script>
<p>First Name: <input data-bind="value:firstName"/></p>
<p>Last Name: <input data-bind="value:lastName"/></p>
<h2>Hello, <span data-bind="text:fullName"></span>!</h2>
I've setup your demo on jsfiddle. It runs perfectly fine. If what you posted is the actual HTML on your page I'd suggest that you include the html, head, and body tags and make sure that knockout210.js is actually being referenced correctly. Also, if you are having trouble with php or whatever, just make a plain old HTML file and it should run.
Here is your exact code that works: http://jsfiddle.net/lucuma/wD8jE/
