Syntax and introduction of CSS attribute behavior

In the CSS page layout, we are accustomed to using cookie when refreshing to retain the contents of the form, but it is really troublesome to do so, and behavior in CSS solves this problem for us. Today I will introduce the syntax of the CSS attribute behavior.

The syntax of behavior:

ExampleSourceCode

Behavior:url (url) | url (# objID) | url (# default#behaviorName)

Value:

Url (url): specify the DHTML behavior component (.htc) with an absolute or relative url address

Url (# objID): using binary implementation (as ActiveX? Control). Where # objID is the value of the id attribute of the object object

Url (# default#behaviorName): the default behavior of IE. Specified by the name identification of the behavior (# behaviorName)

Description: sets or retrieves the DHTML behavior of an object. Multiple behaviors are separated by spaces.

When multiple behaviors attached to the same feature conflict, the result depends on the order in which the behavior is applied to the feature. The priority of the latter behavior is higher than that of the previous one. The same rules apply to name conflicts between properties, events, and methods provided by different behaviors.

◆ can use the addBehavior method to dynamically attach behaviors to objects.

This property is read-only to the currentStyle object. It is readable and writable to other objects.

It is important to note that behaviors defined inline using the behavior property of the style sheet (CSS) or attached using the addBehavior method are not automatically detached when objects are removed from the document tree. The behavior defined by the stylesheet rules in the document is automatically separated when the object is removed from the document tree.

The corresponding script feature is behavior.

Example: ExampleSourceCode

P {behavior:url (# default#download);} div {behavior:url (fly.htc) url (shy.htc);} div {behavior:url (# myObject);}

◆ application 1: refresh also retains the text in the input box

ExampleSourceCode

.sHistory {} {behavior:url (# default#savehistory);}

◆ Application 2: call script

ExampleSourceCode

H2 {behavior:url (behave.htc)} put the mouse here div-CSS.net behave.htc functionhig_lite () {element.style.color=255} functionlow_lite () {element.style.color=0}

Note: try to avoid using Behaviors technology when CSS
