EJS templates embed JavaScript code inside <% ... %> tags, much like
ERB. This library is a port of
Underscore.js's
_.template
function to
Ruby.
Pass an EJS template to EJS.compile to generate a JavaScript
function:
EJS.compile("Hello <%= name %>")
# => "function(obj){...}"
Using the default syntax <%= content %>, content is escaped, à la Rails 3. For unescaped content, use the unescaped syntax <%: content %>.
EJS.compile("Hello <%: name %>")
# => "function(obj){...}"
About the js escape function :
By default, js is escaped using a function injected in each template. To avoid that, save some kb and be more DRY, you can specify your own escape function :
# Example : to use underscore.js escape function, put this in an initializer file (ex. config/initializers/ejs.rb)
EJS.escape_function_name = '_.escape'
Invoke the function in a JavaScript environment to produce a string value. You can pass an optional object specifying local variables for template evaluation.
If you have the ExecJS
library and a suitable JavaScript runtime installed, you can pass a
template and an optional hash of local variables to EJS.evaluate:
EJS.evaluate("Hello <%= name %>", :name => "world")
# => "Hello world"
