- * @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

+</span> * A template class that supports advanced functionality like:
+ *
+ * - Autofilling arrays using templates and sub-templates
+ * - Conditional processing with basic comparison operators
+ * - Basic math function support
+ * - Execute arbitrary inline code with special built-in template variables
+ * - Custom member functions
+ * - 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
+ *
+ * XTemplate provides the templating mechanism built into:
+ *
+ * - {@link Ext.view.View}
+ *
+ * The {@link Ext.Template} describes the acceptable parameters to pass to the constructor. The following examples
+ * demonstrate all of the supported features.
+ *
+ * # Sample Data
+ *
+ * This is the data object used for reference in each code example:
+ *
+ * var data = {
+ * name: 'Tommy Maintz',
+ * title: 'Lead Developer',
+ * company: 'Sencha Inc.',
+ * email: 'tommy@sencha.com',
+ * address: '5 Cups Drive',
+ * city: 'Palo Alto',
+ * state: 'CA',
+ * zip: '44102',
+ * drinks: ['Coffee', 'Soda', 'Water'],
+ * kids: [
+ * {
+ * name: 'Joshua',
+ * age:3
+ * },
+ * {
+ * name: 'Matthew',
+ * age:2
+ * },
+ * {
+ * name: 'Solomon',
+ * age:0
+ * }
+ * ]
+ * };
+ *
+ * # Auto filling of arrays
+ *
+ * The **tpl** tag and the **for** operator are used to process the provided data object:
+ *
+ * - If the value specified in for is an array, it will auto-fill, repeating the template block inside the tpl
+ * tag for each item in the array.
+ * - If for="." is specified, the data object provided is examined.
+ * - While processing an array, the special variable {#} will provide the current array index + 1 (starts at 1, not 0).
+ *
+ * Examples:
+ *
+ * <tpl for=".">...</tpl> // loop through array at root node
+ * <tpl for="foo">...</tpl> // loop through array at foo node
+ * <tpl for="foo.bar">...</tpl> // loop through array at foo.bar node
+ *
+ * Using the sample data above:
+ *
+ * var tpl = new Ext.XTemplate(
+ * '<p>Kids: ',
+ * '<tpl for=".">', // process the data.kids node
+ * '<p>{#}. {name}</p>', // use current array index to autonumber
+ * '</tpl></p>'
+ * );
+ * tpl.overwrite(panel.body, data.kids); // pass the kids property of the data object
+ *
+ * An example illustrating how the **for** property can be leveraged to access specified members of the provided data
+ * object to populate the template:
+ *
+ * var tpl = new Ext.XTemplate(
+ * '<p>Name: {name}</p>',
+ * '<p>Title: {title}</p>',
+ * '<p>Company: {company}</p>',
+ * '<p>Kids: ',
+ * '<tpl for="kids">', // interrogate the kids property within the data
+ * '<p>{name}</p>',
+ * '</tpl></p>'
+ * );
+ * tpl.overwrite(panel.body, data); // pass the root node of the data object
+ *
+ * Flat arrays that contain values (and not objects) can be auto-rendered using the special **`{.}`** variable inside a
+ * loop. This variable will represent the value of the array at the current index:
+ *
+ * var tpl = new Ext.XTemplate(
+ * '<p>{name}\'s favorite beverages:</p>',
+ * '<tpl for="drinks">',
+ * '<div> - {.}</div>',
+ * '</tpl>'
+ * );
+ * tpl.overwrite(panel.body, data);
+ *
+ * When processing a sub-template, for example while looping through a child array, you can access the parent object's
+ * members via the **parent** object:
+ *
+ * var tpl = new Ext.XTemplate(
+ * '<p>Name: {name}</p>',
+ * '<p>Kids: ',
+ * '<tpl for="kids">',
+ * '<tpl if="age &gt; 1">',
+ * '<p>{name}</p>',
+ * '<p>Dad: {parent.name}</p>',
+ * '</tpl>',
+ * '</tpl></p>'
+ * );
+ * tpl.overwrite(panel.body, data);
+ *
+ * # Conditional processing with basic comparison operators
+ *
+ * The **tpl** tag and the **if** operator are used to provide conditional checks for deciding whether or not to render
+ * specific parts of the template. Notes:
+ *
+ * - Double quotes must be encoded if used within the conditional
+ * - There is no else operator -- if needed, two opposite if statements should be used.
+ *
+ * Examples:
+ *
+ * <tpl if="age > 1 && age < 10">Child</tpl>
+ * <tpl if="age >= 10 && age < 18">Teenager</tpl>
+ * <tpl if="this.isGirl(name)">...</tpl>
+ * <tpl if="id==\'download\'">...</tpl>
+ * <tpl if="needsIcon"><img src="{icon}" class="{iconCls}"/></tpl>
+ * // no good:
+ * <tpl if="name == "Tommy"">Hello</tpl>
+ * // encode " if it is part of the condition, e.g.
+ * <tpl if="name == &quot;Tommy&quot;">Hello</tpl>
+ *
+ * Using the sample data above:
+ *
+ * var tpl = new Ext.XTemplate(
+ * '<p>Name: {name}</p>',
+ * '<p>Kids: ',
+ * '<tpl for="kids">',
+ * '<tpl if="age &gt; 1">',
+ * '<p>{name}</p>',
+ * '</tpl>',
+ * '</tpl></p>'
+ * );
+ * tpl.overwrite(panel.body, data);
+ *
+ * # Basic math support
+ *
+ * The following basic math operators may be applied directly on numeric data values:
+ *
+ * + - * /
+ *
+ * For example:
+ *
+ * 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);
+ *
+ * # Execute arbitrary inline code with special built-in template variables
+ *
+ * Anything between `{[ ... ]}` is considered code to be executed in the scope of the template. There are some special
+ * variables available in that code:
+ *
+ * - **values**: The values in the current scope. If you are using scope changing sub-templates,
+ * you can change what values is.
+ * - **parent**: The scope (values) of the ancestor template.
+ * - **xindex**: If you are in a looping template, the index of the loop you are in (1-based).
+ * - **xcount**: If you are in a looping template, the total length of the array you are looping.
+ *
+ * This example demonstrates basic row striping using an inline code block and the xindex variable:
+ *
+ * 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);
+ *
+ * # Template member functions
+ *
+ * One or more member functions can be specified in a configuration object passed into the XTemplate constructor for
+ * more complex processing:
+ *
+ * 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>',
+ * // use opposite if statement to simulate 'else' processing:
+ * '<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>',
+ * {
+ * // XTemplate configuration:
+ * disableFormats: true,
+ * // member functions:
+ * isGirl: function(name){
+ * return name == 'Sara Grace';
+ * },
+ * isBaby: function(age){
+ * return age < 1;
+ * }
+ * }
+ * );
+ * tpl.overwrite(panel.body, data);
