Fast, simple string-based micro-templating engine similar to ERB or Underscore templates.
compiletext
[options]
Compiles a template string into a JavaScript function. Pass a data object to the function to render the template using the given data and get back a rendered string.
Within a template, use <%= ... %> to output the value of an expression (where
... is the JavaScript expression or data variable to evaluate). The output
will be HTML-escaped by default. To output a raw value without escaping, use
<%== ... %>, but be careful not to do this with untrusted user input.
To execute arbitrary JavaScript code within the template without rendering its
output, use <% ... %>, where ... is the code to be executed. This allows the
use of if/else blocks, loops, function calls, etc., although it's recommended
that you avoid embedding anything beyond basic flow control logic in your
templates.
Properties of the data object passed to a template function are made available
on a data variable within the scope of the template. So, if you pass in
the object {message: 'hello!'}, you can print the value of the message
property using <%= data.message %>.
Compiled template function. Execute this function and pass in a data object to render the template with the given data.
YUI().use('template-micro', function (Y) {
var template = '<ul class="<%= data.classNames.list %>">' +
'<% Y.Array.each(data.items, function (item) { %>' +
'<li><%= item %></li>' +
'<% }); %>' +
'</ul>';
// Compile the template into a function.
var compiled = Y.Template.Micro.compile(template);
// Render the template to HTML, passing in the data to use.
var html = compiled({
classNames: {list: 'demo'},
items : ['one', 'two', 'three', 'four']
});
});precompiletext
[options]
Precompiles the given template text into a string of JavaScript source code that can be evaluated later in another context (or on another machine) to render the template.
A common use case is to precompile templates at build time or on the server, then evaluate the code on the client to render a template. The client only needs to revive and render the template, avoiding the work of the compilation step.
Source code for the precompiled template.
rendertext
data
[options]
Compiles and renders the given template text in a single step.
This can be useful for single-use templates, but if you plan to render the same
template multiple times, it's much better to use compile() to compile it once,
then simply call the compiled function multiple times to avoid recompiling.
Rendered result.
reviveprecompiled
Revives a precompiled template function into a normal compiled template function
that can be called to render the template. The precompiled function must already
have been evaluated to a function -- you can't pass raw JavaScript code to
revive().
precompiled
Function
Precompiled template function.
Revived template function, ready to be rendered.
optionsDefault options for Y.Template.Micro.
[code]
RegExp
optional
Regex that matches code blocks like
<% ... %>.
[escapedOutput]
RegExp
optional
Regex that matches escaped output
tags like <%= ... %>.
[rawOutput]
RegExp
optional
Regex that matches raw output tags like
<%== ... %>.
[stringEscape]
RegExp
optional
Regex that matches characters that need to be escaped inside single-quoted JavaScript string literals.
[stringReplace]
Object
optional
Hash that maps characters matched by
stringEscape to the strings they should be replaced with. If you add
a character to the stringEscape regex, you need to add it here too or
it will be replaced with an empty string.
