Binding Element Attributes Edit Page

In addition to normal text, you may also want to have your templates contain HTML elements whose attributes are bound to the controller.

For example, imagine your controller has a property that contains a URL to an image:

1
2
3

<div id="logo">
  <img {{bind-attr src=logoUrl}} alt="Logo">
</div>

This generates the following HTML:

1
2
3

<div id="logo">
  <img src="http://www.example.com/images/logo.png" alt="Logo">
</div>

If you use {{bind-attr}} with a Boolean value, it will add or remove the specified attribute. For example, given this template:

1

<input type="checkbox" {{bind-attr disabled=isAdministrator}}>

If isAdministrator is true, Handlebars will produce the following HTML element:

1

<input type="checkbox" disabled>

If isAdministrator is false, Handlebars will produce the following:

1

<input type="checkbox">
