Hierarchy
Ext.BaseExt.data.JsonPFiles
This class is used to create JSONP requests. JSONP is a mechanism that allows for making\nrequests for data cross domain. More information is available here.
\nSpecifies the GET parameter that will be sent to the server containing the function name to be executed when\nthe request completes. Defaults to callback. Thus, a common request will be in the form of\nurl?callback=Ext.data.JsonP.callback1
\nDefaults to: "callback"
True to add a unique cache-buster param to requests. Defaults to true.
\nDefaults to: true
Change the parameter which is sent went disabling caching through a cache buster. Defaults to '_dc'.
\nDefaults to: "_dc"
Number of requests done so far.
\nDefaults to: 0
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
\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
\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
\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
\nthis
\nLoads the script for the given request by appending it to the HEAD element. This is\nits own method so that users can override it (as well as createScript).
\nThe request object.
\nMakes a JSONP request.
\nAn object which may contain the following properties. Note that options will\ntake priority over any defaults that are specified in the class.
\n\nrequest An object containing the request details.
\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
