CSS Property behavior Syntax

In the CSS page layout, we encountered the refresh to keep the contents of the form when the habit of using cookies, but that is very cumbersome to do, CSS behavior for us to solve the problem well. Today we will introduce the syntax of CSS property behavior.

Behavior property Syntax:

Examplesourcecode

    1. Behavior:url (URL) |url (#objID) |url (#default #behaviorname)

Value:

URL (URL): Specifies the DHTML behavior component (. htc) with an absolute or relative URL address

URL (#objID): The behavior of using a binary implementation (as a activex® control). The #objid here is the ID property value of the object.

URL (#default #behaviorname): The default behavior of IE. specified by the name Identification (#behaviorName) of the behavior

Description: Sets or retrieves the DHTML behavior of an object. Multiple behaviors are separated by a space.

When multiple behaviors that are 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 the previous behavior. The same rules apply to the name conflicts that occur with properties, events, and methods that are provided by different behaviors.

You can use the Addbehavior method to dynamically attach a behavior to an object.

This property is read-only for Currentstyle objects. Readable and writable for other objects.

It is important to note that using the Behavior property of the style sheet (CSS) inline definition or the behavior attached using the Addbehavior method is not automatically detached when the object is removed from the document tree. The behavior defined by the style sheet rule in the document is automatically detached when the object is removed from the document tree.

The corresponding script attribute is behavior.

Example:

Examplesourcecode

    1. P{behavior:url (#default #download);}
    2. Div{behavior:url (FLY.HTC) URL (shy.htc);}
    3. Div{behavior:url (#myObject);}

App 1: Refresh also preserves text inside the input box

Examplesourcecode

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

App 2: Invoke script

Examplesourcecode

  2. <html>
  4. <head>
  6. <style>
  8. H1{behavior:url (BEHAVE.HTC)}
  10. </style>
  12. </head>
  14. <body>
  16. <H1> put the mouse here 52css.com</H1>
  18. </body>
  20. </html>
  22. Behave.htc
  26. <component>
  28. <attachforattachfor= "element"event= "onmouseover"handler=" hig_lite"/>
  30. <attachforattachfor= "element"event= "onmouseout"handler=" low_lite"/>
  32. <scripttypescripttype="Text/javascript">
  34. Functionhig_lite ()
  36. {
  38. element.style.color=255
  40. }
  42. Functionlow_lite ()
  44. {
  46. element.style.color=0
  48. }
  50. </Script>
  52. </Component>
