Template7 使用


In the downloaded/installed package we need JavaScript files (.js) from the dist/ folder.

And include required script in our HTML page:

<html>
    <head>
        ...
        <script src="path/to/template7.min.js"></script>
    </head>
    <body>
        ...
    </body>
</html>

Templates

Template7 templates looks like Handlebars templates, it is like regular HTML but with embedded handlebars expressions:

<div class="list-block">
  <ul>
    {{#each items}}
    <li class="item-content">
      <div class="item-inner">
        <div class="item-title">{{title}}</div>
      </div>
    </li>
    {{/each}}
  </ul>
</div>

Expressions syntax

Template7 support expressions with the following syntax:

Variables:

  • {{title}} - plain variable. Outputs "title" variable in current context

  • {{../title}} - plain variable. Outputs "title" variable in parent context

  • {{../../title}} - plain variable. Outputs "title" variable in parent context of parent context

  • {{this}} - plain variable. Outputs variable equals to current context

  • {{person.name}} - plain variable. Outputs variable equals to "name" property of "person" variable in current context

  • {{../person.name}} - plain variable. The same but for parent context

  • {{@index}} - access to additional data variable. Such data variables could be used in helpers

Block expressions

  • {{#each}} - begin of block expression

  • {{else}} - begin of block inverse expression (where supported)

  • {{/each}} - end of block expression

  • {{#each reverse="true"}} - begin of block expression with passed reverse:true hash arguments

Helpers

Helpers could be plain expressions and block expressions:

  • {{join myArray delimiter=", "}} - execute "join" helper and pass there "myArray" variable of current context and delimiter:', ' hash argument

Compilation and Rendering

Template7 is a globally available Window function.

First of all we need to deliver string template. For example, we can store in script tag:

<script id="template" type="text/template7">
    <p>Hello, my name is {{firstName}} {{lastName}}</p>
</script>

Now we need to compile it in JavaScript. Template7 will convert our template string to plain JavaScript function:

var template = $$('#template').html();
 
// compile it with Template7
var compiledTemplate = Template7.compile(template);
 
// Now we may render our compiled template by passing required context
var context = {
    firstName: 'John',
    lastName: 'Doe'
};
var html = compiledTemplate(context);

Now, html variable will contain:

<p>Hello, my name is John Doe</p>
