sectionRenderer

typedef

Renders a section. These functions are usually provided as .fn and .inverse on a stache helper's options.

`function(context, helpers)`

Parameters

context {*|can-view-scope}:
Specifies the data the section is rendered with. If a can-view-scope is provided, that scope is used to render the section. If anything else is provided, it is used to create a new scope object with the current scope as it's parent. If nothing is provided, the current scope is used to render the section.
helpers {*|Options}:
Specifies the helpers the section is rendered with. If a Options is provided, that scope is used to render the section. If anything else is provided, it is used to create a new scope object with the current helper scope as it's parent. If nothing is provided, the current helper scope is used to render the section.

Returns

{documentFragment|String}:

Returns the rendered result of the helper. If the section is within a tag, like:

<h1 {{#helper}}class='power'{{/helper}}>

a String is returned.

If the section is outside a tag like:

<div> {{#helper}}<h2>Tasks</h2>{{/helper}} </div>

a documentFragment is returned.

Use

Renderer functions are provided to stache helpers on the options argument and are used to render the content between sections. The context and helpers option let you control the data and helpers used to render the section.

The following example adds {first: "Justin"} to the lookup data. Notice how the section has access to first and last.

stache.registerHelper("myhelper", function(options){
  var section = options.fn({first: "Justin"});
  return $("<h1>").append( section );
})

var template = stache(
  "{{#helper}}{{first}} {{last}}{{/helper}}");
  
template({last: "Meyer"}) //-> <h1>Justin Meyer</h1>

If no context is provided, the current context is passed. Notice how the section has access to last:

stache.registerHelper("myhelper", function(options){
  
   var section = options.fn();
   return $("<h1>").append( section );
  
});

var template = stache(
  "{{#helper}}{{first}} {{last}}{{/helper}}");
  
template({last: "Meyer"}) //-> <h1> Meyer</h1>

If a can-view-scope is provided, it is used to render the section. Notice how last is not available in the section:

stache.registerHelper("myhelper", function(options){
  
  var section = options.fn( new Scope( {first: "Justin"}) );
  return $("<h1>").append( section );
  
});

var template = stache(
  "{{#helper}}{{first}} {{last}}{{/helper}}");
  
template({last: "Meyer"}) //-> <h1>Justin </h1>
