Working With Plain Objects (using normal objects)

Currently, only ordinary JavaScript objects wrapped in jQuery are supported: .data (), .prop (), .bind (), .unbind (), .trigger (), and .triggerHandler (). Using .data () (or any method that returns .data ()), a new property named jQuery {randomNumber} (such as jQuery123456789) is generated in a normal object.

/ / define a plain object

Var foo = {foo: "bar", hello: "world"}

/ / Pass it to the jQuery function

Var $foo = $(foo)

/ / test accessing property values

Var test1 = $foo.prop ("foo"); / / bar

/ / test setting property values

$foo.prop ("foo", "foobar")

Var test2 = $foo.prop ("foo"); / / foobar

/ / test using .data () as summarized above

$foo.data ("keyName", "someValue")

Console.log ($foo); / / will now contain a jQuery {randomNumber} property

/ / test binding an event name and triggering

$foo.bind ("eventName", function () {

Console.log ("eventName was called")

})

$foo.trigger ("eventName"); / / logs "eventName was called"

If .trigger ("eventName") is used, it searches for a "eventName" property on the object and tries to execute any processor attached to the jQuery after execution is complete. It does not check whether the property is a function. In order to avoid this situation, .dispaterHandler ("eventName") should be used instead.

$foo.triggerHandler ("eventName"); / / also logs "eventName was called"
