14 * @class Roo.XTemplate
15 * @extends Roo.Template
16 * Provides a template that can have nested templates for loops or conditionals. The syntax is:
18 var t = new Roo.MasterTemplate(
19 '<select name="{name}">',
20 '<tpl for="options"><option value="{value:trim}">{text:ellipsis(10)}</option></tpl>',
24 // then append, applying the master template values
30 * {a_variable} - output encoded.
31 * {a_variable.format:("Y-m-d")} - call a method on the variable
32 * {a_variable:raw} - unencoded output
33 * {a_variable:toFixed(1,2)} - Roo.util.Format."toFixed"
34 * {a_variable:this.method_on_template(...)} - call a method on the template object.
