Chapter 16: Behaviors Behaviors let users make their HTML pages interactive. They offer web designers an easy way to assign actions to page elements by filling in an HTML form. The term behavior refers to the combination of an event (such as onClick, onLoad, or onSubmit) and an action (such as Check Plugin, Go to URL, Swap Image). The browser determines which HTML elements accept which events. Files that list events that each browser supports are stored in the Configuration/Behaviors/Events folder within the Adobe Dreamweaver CS3 application folder. Actions are the part of a behavior that you can control; when you write a behavior, you're really writing an Action file. Actions are HTML files. The body section of an Action file generally contains an HTML form that accepts parameters for the action (for example, parameters that indicate which absolutely positioned elements to display or hide). The head section of an Action file contains JavaScript functions that process form input from the body content and control the functions, arguments, and event handlers that are inserted into a user's document. You should write behavior actions when you want to share functions with users or when you want to insert the same JavaScript function repeatedly, but change the parameters each time. Note: You cannot use behaviors to insert VBScript functions directly; however, you can add a VBScript function indirectly by editing the Document Object Model (DOM) in the applyBehavior() function. The following table lists the files you use to create behavior actions: Path File Description Configuration/Behaviors/Actions/ behavior action.htm The body of the file contains an HTML form for the action's parameters. The head of the file contains the JavaScript functions. Note: For information about server behaviors that provide web application functionality, see "Server behaviors" on page 243.

Chapter 16: Behaviors
Behaviors let users make their HTML pages interactive. They offer web designers an easy way to
assign actions to page elements by filling in an HTML form.
The term
behavior
refers to the combination of an event (such as
onClick
,
onLoad
, or
onSubmit
) and an action (such as Check Plugin, Go to URL, Swap Image). The browser deter-
mines which HTML elements accept which events. Files that list events that each browser
supports are stored in the Configuration/Behaviors/Events folder within the Adobe
Dreamweaver CS3 application folder.
Actions are the part of a behavior that you can control; when you write a behavior, you’re really
writing an Action file. Actions are HTML files. The body section of an Action file generally
contains an HTML form that accepts parameters for the action (for example, parameters that
indicate which absolutely positioned elements to display or hide). The head section of an Action
file contains JavaScript functions that process form input from the body content and control the
functions, arguments, and event handlers that are inserted into a user’s document.
You should write behavior actions when you want to share functions with users or when you
want to insert the same JavaScript function repeatedly, but change the parameters each time.
Note:
You cannot use behaviors to insert VBScript functions directly; however, you can add a
VBScript function indirectly by editing the Document Object Model (DOM) in the
applyBehavior()
function.
The following table lists the files you use to create behavior actions:

For information about server behaviors that provide web application functionality, see
