- * @class Ext.XTemplate
- * @extends Ext.Template
- * <p>A template class that supports advanced functionality like autofilling arrays, conditional processing with
- * basic comparison operators, sub-templates, basic math function support, special built-in template variables,
- * inline code execution and more. XTemplate also provides the templating mechanism built into {@link Ext.DataView}.</p>
- * <p>XTemplate supports many special tags and built-in operators that aren't defined as part of the API, but are
- * supported in the templates that can be created. The following examples demonstrate all of the supported features.
- * This is the data object used for reference in each code example:</p>
- * <pre><code>
-var data = {
- name: 'Jack Slocum',
- title: 'Lead Developer',
- company: 'Ext JS, LLC',
- email: 'jack@extjs.com',
- address: '4 Red Bulls Drive',
- city: 'Cleveland',
- state: 'Ohio',
- zip: '44102',
- drinks: ['Red Bull', 'Coffee', 'Water'],
- kids: [{
- name: 'Sara Grace',
- age:3
- },{
- name: 'Zachary',
- age:2
- },{
- name: 'John James',
- age:0
- }]
-};
- * </code></pre>
- * <p><b>Auto filling of arrays</b><br/>The <tt>tpl</tt> tag and the <tt>for</tt> operator are used
- * to process the provided data object. If <tt>for="."</tt> is specified, the data object provided
- * is examined. If the variable in <tt>for</tt> is an array, it will auto-fill, repeating the template
- * block inside the <tt>tpl</tt> tag for each item in the array:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Kids: ',
- '<tpl for=".">',
- '<p>{name}</p>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
- * </code></pre>
- * <p><b>Scope switching</b><br/>The <tt>for</tt> property can be leveraged to access specified members
- * of the provided data object to populate the template:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Title: {title}</p>',
- '<p>Company: {company}</p>',
- '<p>Kids: ',
- '<tpl <b>for="kids"</b>>', // interrogate the kids property within the data
- '<p>{name}</p>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data);
- * </code></pre>
- * <p><b>Access to parent object from within sub-template scope</b><br/>When processing a sub-template, for example while
- * looping through a child array, you can access the parent object's members via the <tt>parent</tt> object:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Kids: ',
- '<tpl for="kids">',
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded
- '<p>{name}</p>',
- '<p>Dad: {parent.name}</p>',
- '</tpl>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data);
-</code></pre>
- * <p><b>Array item index and basic math support</b> <br/>While processing an array, the special variable <tt>{#}</tt>
- * will provide the current array index + 1 (starts at 1, not 0). Templates also support the basic math operators
- * + - * and / that can be applied directly on numeric data values:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Kids: ',
- '<tpl for="kids">',
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded
- '<p>{#}: {name}</p>', // <-- Auto-number each item
- '<p>In 5 Years: {age+5}</p>', // <-- Basic math
- '<p>Dad: {parent.name}</p>',
- '</tpl>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data);
-</code></pre>
- * <p><b>Auto-rendering of flat arrays</b> <br/>Flat arrays that contain values (and not objects) can be auto-rendered
- * using the special <tt>{.}</tt> variable inside a loop. This variable will represent the value of
- * the array at the current index:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>{name}\'s favorite beverages:</p>',
- '<tpl for="drinks">',
- '<div> - {.}</div>',
- '</tpl>'
-);
-tpl.overwrite(panel.body, data);
-</code></pre>
- * <p><b>Basic conditional logic</b> <br/>Using the <tt>tpl</tt> tag and the <tt>if</tt>
- * operator you can provide conditional checks for deciding whether or not to render specific parts of the template.
- * Note that there is no <tt>else</tt> operator — if needed, you should use two opposite <tt>if</tt> statements.
- * Properly-encoded attributes are required as seen in the following example:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Kids: ',
- '<tpl for="kids">',
- '<tpl if="age &gt; 1">', // <-- Note that the > is encoded
- '<p>{name}</p>',
- '</tpl>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data);
-</code></pre>
- * <p><b>Ability to execute arbitrary inline code</b> <br/>In an XTemplate, anything between {[ ... ]} is considered
- * code to be executed in the scope of the template. There are some special variables available in that code:
- * <ul>
- * <li><b><tt>values</tt></b>: The values in the current scope. If you are using scope changing sub-templates, you
- * can change what <tt>values</tt> is.</li>
- * <li><b><tt>parent</tt></b>: The scope (values) of the ancestor template.</li>
- * <li><b><tt>xindex</tt></b>: If you are in a looping template, the index of the loop you are in (1-based).</li>
- * <li><b><tt>xcount</tt></b>: If you are in a looping template, the total length of the array you are looping.</li>
- * <li><b><tt>fm</tt></b>: An alias for <tt>Ext.util.Format</tt>.</li>
- * </ul>
- * This example demonstrates basic row striping using an inline code block and the <tt>xindex</tt> variable:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Company: {[values.company.toUpperCase() + ", " + values.title]}</p>',
- '<p>Kids: ',
- '<tpl for="kids">',
- '<div class="{[xindex % 2 === 0 ? "even" : "odd"]}">',
- '{name}',
- '</div>',
- '</tpl></p>'
-);
-tpl.overwrite(panel.body, data);
-</code></pre>
- * <p><b>Template member functions</b> <br/>One or more member functions can be defined directly on the config
- * object passed into the XTemplate constructor for more complex processing:</p>
- * <pre><code>
-var tpl = new Ext.XTemplate(
- '<p>Name: {name}</p>',
- '<p>Kids: ',
- '<tpl for="kids">',
- '<tpl if="this.isGirl(name)">',
- '<p>Girl: {name} - {age}</p>',
- '</tpl>',
- '<tpl if="this.isGirl(name) == false">',
- '<p>Boy: {name} - {age}</p>',
- '</tpl>',
- '<tpl if="this.isBaby(age)">',
- '<p>{name} is a baby!</p>',
- '</tpl>',
- '</tpl></p>', {
- isGirl: function(name){
- return name == 'Sara Grace';
- },
- isBaby: function(age){
- return age < 1;
- }
-});
-tpl.overwrite(panel.body, data);
-</code></pre>
- * @constructor
- * @param {String/Array/Object} parts The HTML fragment or an array of fragments to join(""), or multiple arguments
- * to join("") that can also include a config object
