/**
|
|
* jQuery plugin for micro templates
|
|
*
|
|
* Strings are automatically escaped, but that can be disabled by setting
|
|
* escapeFunction to null.
|
|
*
|
|
* Usage examples:
|
|
*
|
|
* var htmlStr = '<p>Bake, uncovered, until the {greasystuff} is melted and the {pasta} is heated through, about {min} minutes.</p>'
|
|
* $(htmlStr).octemplate({greasystuff: 'cheese', pasta: 'macaroni', min: 10});
|
|
*
|
|
* var htmlStr = '<p>Welcome back {user}</p>';
|
|
* $(htmlStr).octemplate({user: 'John Q. Public'}, {escapeFunction: null});
|
|
*
|
|
* Be aware that the target string must be wrapped in an HTML element for the
|
|
* plugin to work. The following won't work:
|
|
*
|
|
* var textStr = 'Welcome back {user}';
|
|
* $(textStr).octemplate({user: 'John Q. Public'});
|
|
*
|
|
* For anything larger than one-liners, you can use a simple $.get() ajax
|
|
* request to get the template, or you can embed them it the page using the
|
|
* text/template type:
|
|
*
|
|
* <script id="contactListItemTemplate" type="text/template">
|
|
* <tr class="contact" data-id="{id}">
|
|
* <td class="name">
|
|
* <input type="checkbox" name="id" value="{id}" /><span class="nametext">{name}</span>
|
|
* </td>
|
|
* <td class="email">
|
|
* <a href="mailto:{email}">{email}</a>
|
|
* </td>
|
|
* <td class="phone">{phone}</td>
|
|
* </tr>
|
|
* </script>
|
|
*
|
|
* var $tmpl = $('#contactListItemTemplate');
|
|
* var contacts = // fetched in some ajax call
|
|
*
|
|
* $.each(contacts, function(idx, contact) {
|
|
* $contactList.append(
|
|
* $tmpl.octemplate({
|
|
* id: contact.getId(),
|
|
* name: contact.getDisplayName(),
|
|
* email: contact.getPreferredEmail(),
|
|
* phone: contact.getPreferredPhone(),
|
|
* });
|
|
* );
|
|
* });
|
|
