Represents an HTML fragment template. Templates may be precompiled for greater performance.
\n\nAn instance of this class may be created by passing to the constructor either a single argument, or multiple\narguments:
\n\nThe single argument may be either a String or an Array:
\n\nString:
\n\nvar t = new Ext.Template(\"<div>Hello {0}.</div>\");\nt.append('some-element', ['foo']);\n
Array:
\n\nAn Array will be combined with join('')
.
var t = new Ext.Template([\n '<div name=\"{id}\">',\n '<span class=\"{cls}\">{name:trim} {value:ellipsis(10)}</span>',\n '</div>',\n]);\nt.compile();\nt.append('some-element', {id: 'myid', cls: 'myclass', name: 'foo', value: 'bar'});\n
Multiple arguments will be combined with join('')
.
var t = new Ext.Template(\n '<div name=\"{id}\">',\n '<span class=\"{cls}\">{name} {value}</span>',\n '</div>',\n // a configuration object:\n {\n compiled: true, // compile immediately\n }\n);\n
\n\ndisableFormats
reduces apply
time when no formatting is required.True to immediately compile the template. Defaults to false.
\ntrue
in this class to identify an object as an instantiated Template, or subclass thereof.
Defaults to: true
Get the reference to the current class from which this object was instantiated. Unlike statics,\nthis.self
is scope-dependent and it's meant to be used for dynamic inheritance. See statics\nfor a detailed comparison
Ext.define('My.Cat', {\n statics: {\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n alert(this.self.speciesName); // dependent on 'this'\n },\n\n clone: function() {\n return new this.self();\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat'\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\n
\nApplies the supplied values
to the template and appends the new node(s) to the specified el
.
For example usage see Ext.Template class docs.
\nThe context element
\nThe template values. See applyTemplate for details.
\ntrue to return an Ext.Element.
\nThe new node or Element
\nReturns an HTML fragment of this template with the specified values applied.
\nThe template values. Can be an array if your params are numeric:
\n\n\n\n\nvar tpl = new Ext.Template('Name: {0}, Age: {1}');\ntpl.apply(['John', 25]);\n
\n\n\n\n\nor an object:
\n\n\n\n\nvar tpl = new Ext.Template('Name: {name}, Age: {age}');\ntpl.apply({name: 'John', age: 25});\n
\n\nThe HTML fragment
\n\nAlias for apply.
\n\nReturns an HTML fragment of this template with the specified values applied.
\nThe template values. Can be an array if your params are numeric:
\n\n\n\n\nvar tpl = new Ext.Template('Name: {0}, Age: {1}');\ntpl.apply(['John', 25]);\n
\n\n\n\n\nor an object:
\n\n\n\n\nvar tpl = new Ext.Template('Name: {name}, Age: {age}');\ntpl.apply({name: 'John', age: 25});\n
\n\nThe HTML fragment
\n\nCall the original method that was previously overridden with override
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callOverridden();\n\n alert(\"Meeeeoooowwww\");\n }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n // alerts \"I'm a cat!\"\n // alerts \"Meeeeoooowwww\"\n
\n This method has been deprecated
\nas of 4.1. Use callParent instead.
\n\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callOverridden(arguments)
Returns the result of calling the overridden method
\nCall the \"parent\" method of the current method. That is the method previously\noverridden by derivation or by an override (see Ext.define).
\n\n Ext.define('My.Base', {\n constructor: function (x) {\n this.x = x;\n },\n\n statics: {\n method: function (x) {\n return x;\n }\n }\n });\n\n Ext.define('My.Derived', {\n extend: 'My.Base',\n\n constructor: function () {\n this.callParent([21]);\n }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x); // alerts 21\n
\n\nThis can be used with an override as follows:
\n\n Ext.define('My.DerivedOverride', {\n override: 'My.Derived',\n\n constructor: function (x) {\n this.callParent([x*2]); // calls original My.Derived constructor\n }\n });\n\n var obj = new My.Derived();\n\n alert(obj.x); // now alerts 42\n
\n\nThis also works with static methods.
\n\n Ext.define('My.Derived2', {\n extend: 'My.Base',\n\n statics: {\n method: function (x) {\n return this.callParent([x*2]); // calls My.Base.method\n }\n }\n });\n\n alert(My.Base.method(10); // alerts 10\n alert(My.Derived2.method(10); // alerts 20\n
\n\nLastly, it also works with overridden static methods.
\n\n Ext.define('My.Derived2Override', {\n override: 'My.Derived2',\n\n statics: {\n method: function (x) {\n return this.callParent([x*2]); // calls My.Derived2.method\n }\n }\n });\n\n alert(My.Derived2.method(10); // now alerts 40\n
\n\nTo override a method and replace it and also call the superclass method, use\ncallSuper. This is often done to patch a method to fix a bug.
\nThe arguments, either an array or the arguments
object\nfrom the current method, for example: this.callParent(arguments)
Returns the result of calling the parent method
\nThis method is used by an override to call the superclass method but bypass any\noverridden method. This is often done to \"patch\" a method that contains a bug\nbut for whatever reason cannot be fixed directly.
\n\nConsider:
\n\n Ext.define('Ext.some.Class', {\n method: function () {\n console.log('Good');\n }\n });\n\n Ext.define('Ext.some.DerivedClass', {\n method: function () {\n console.log('Bad');\n\n // ... logic but with a bug ...\n\n this.callParent();\n }\n });\n
\n\nTo patch the bug in DerivedClass.method
, the typical solution is to create an\noverride:
Ext.define('App.paches.DerivedClass', {\n override: 'Ext.some.DerivedClass',\n\n method: function () {\n console.log('Fixed');\n\n // ... logic but with bug fixed ...\n\n this.callSuper();\n }\n });\n
\n\nThe patch method cannot use callParent
to call the superclass method
since\nthat would call the overridden method containing the bug. In other words, the\nabove patch would only produce \"Fixed\" then \"Good\" in the console log, whereas,\nusing callParent
would produce \"Fixed\" then \"Bad\" then \"Good\".
The arguments, either an array or the arguments
object\nfrom the current method, for example: this.callSuper(arguments)
Returns the result of calling the superclass method
\nCompiles the template into an internal function, eliminating the RegEx overhead.
\nthis
\nInitialize configuration for this class. a typical example:
\n\nExt.define('My.awesome.Class', {\n // The default config\n config: {\n name: 'Awesome',\n isAwesome: true\n },\n\n constructor: function(config) {\n this.initConfig(config);\n }\n});\n\nvar awesome = new My.awesome.Class({\n name: 'Super Awesome'\n});\n\nalert(awesome.getName()); // 'Super Awesome'\n

\nThe new node or Element
\nGet the reference to the class from which this object was instantiated. Note that unlike self,\nthis.statics()
is scope-independent and it always returns the class from which it was called, regardless of what\nthis
points to during run-time
Ext.define('My.Cat', {\n statics: {\n totalCreated: 0,\n speciesName: 'Cat' // My.Cat.speciesName = 'Cat'\n },\n\n constructor: function() {\n var statics = this.statics();\n\n alert(statics.speciesName); // always equals to 'Cat' no matter what 'this' refers to\n // equivalent to: My.Cat.speciesName\n\n alert(this.self.speciesName); // dependent on 'this'\n\n statics.totalCreated++;\n },\n\n clone: function() {\n var cloned = new this.self; // dependent on 'this'\n\n cloned.groupName = this.statics().speciesName; // equivalent to: My.Cat.speciesName\n\n return cloned;\n }\n});\n\n\nExt.define('My.SnowLeopard', {\n extend: 'My.Cat',\n\n statics: {\n speciesName: 'Snow Leopard' // My.SnowLeopard.speciesName = 'Snow Leopard'\n },\n\n constructor: function() {\n this.callParent();\n }\n});\n\nvar cat = new My.Cat(); // alerts 'Cat', then alerts 'Cat'\n\nvar snowLeopard = new My.SnowLeopard(); // alerts 'Cat', then alerts 'Snow Leopard'\n\nvar clone = snowLeopard.clone();\nalert(Ext.getClassName(clone)); // alerts 'My.SnowLeopard'\nalert(clone.groupName); // alerts 'Cat'\n\nalert(My.Cat.totalCreated); // alerts 3\n
\nAdd methods / properties to the prototype of this class.
\n\nExt.define('My.awesome.Cat', {\n constructor: function() {\n ...\n }\n});\n\n My.awesome.Cat.addMembers({\n meow: function() {\n alert('Meowww...');\n }\n });\n\n var kitty = new My.awesome.Cat;\n kitty.meow();\n
\nAdd / override static properties of this class.
\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.addStatics({\n someProperty: 'someValue', // My.cool.Class.someProperty = 'someValue'\n method1: function() { ... }, // My.cool.Class.method1 = function() { ... };\n method2: function() { ... } // My.cool.Class.method2 = function() { ... };\n});\n
\nthis
\nBorrow another class' members to the prototype of this class.
\n\nExt.define('Bank', {\n money: '$$$',\n printMoney: function() {\n alert('$$$$$$$');\n }\n});\n\nExt.define('Thief', {\n ...\n});\n\nThief.borrow(Bank, ['money', 'printMoney']);\n\nvar steve = new Thief();\n\nalert(steve.money); // alerts '$$$'\nsteve.printMoney(); // alerts '$$$$$$$'\n
\nThe class to borrow members from
\nThe names of the members to borrow
\nthis
\nCreate a new instance of this Class.
\n\nExt.define('My.cool.Class', {\n ...\n});\n\nMy.cool.Class.create({\n someConfig: true\n});\n
\n\nAll parameters are passed to the constructor of the class.
\nthe created instance.
\nCreate aliases for existing prototype methods. Example:
\n\nExt.define('My.cool.Class', {\n method1: function() { ... },\n method2: function() { ... }\n});\n\nvar test = new My.cool.Class();\n\nMy.cool.Class.createAlias({\n method3: 'method1',\n method4: 'method2'\n});\n\ntest.method3(); // test.method1()\n\nMy.cool.Class.createAlias('method5', 'method3');\n\ntest.method5(); // test.method3() -> test.method1()\n
\nThe new method name, or an object to set multiple aliases. See\nflexSetter
\nThe original method name
\nCreates a template from the passed element's value (display:none textarea, preferred) or innerHTML.
\nThe created template
\nGet the current class' name in string format.
\n\nExt.define('My.cool.Class', {\n constructor: function() {\n alert(this.self.getName()); // alerts 'My.cool.Class'\n }\n});\n\nMy.cool.Class.getName(); // 'My.cool.Class'\n
\nclassName
\nAdds members to class.
\nThis method has been deprecated since 4.1
\nUse addMembers instead.
\n\nOverride members of this class. Overridden methods can be invoked via\ncallParent.
\n\nExt.define('My.Cat', {\n constructor: function() {\n alert(\"I'm a cat!\");\n }\n});\n\nMy.Cat.override({\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callParent(arguments);\n\n alert(\"Meeeeoooowwww\");\n }\n});\n\nvar kitty = new My.Cat(); // alerts \"I'm going to be a cat!\"\n // alerts \"I'm a cat!\"\n // alerts \"Meeeeoooowwww\"\n
\n\nAs of 4.1, direct use of this method is deprecated. Use Ext.define\ninstead:
\n\nExt.define('My.CatOverride', {\n override: 'My.Cat',\n constructor: function() {\n alert(\"I'm going to be a cat!\");\n\n this.callParent(arguments);\n\n alert(\"Meeeeoooowwww\");\n }\n});\n
\n\nThe above accomplishes the same result but can be managed by the Ext.Loader\nwhich can properly order the override and its target class and the build process\ncan determine whether the override is needed based on the required state of the\ntarget class (My.Cat).
\nThis method has been deprecated since 4.1.0
\nUse Ext.define instead
\n\nThe properties to add to this class. This should be\nspecified as an object literal containing one or more properties.
