EXTENDING DREAMWEAVER CS4

Server behaviors

• The belowHTML[+weight] value is similar to the aboveHTML value, except that participants are added below the

closing

/HTML tag.

• The beforeSelection value inserts the text before the current selection or insertion point. If there is no selection, it

inserts the text at the end of the

body tag.

• The replaceSelection value replaces the current selection with the text. If there is no selection, it inserts the text at

the end of the

body tag.

• The wrapSelection value balances the current selection, inserts a block tag before the selection, and adds the

appropriate closing tag after the selection.

• The afterSelection value inserts the text after the current selection or insertion point. If there is no selection, it

inserts the text at the end of the

body tag.

• The beforeNode value inserts the text before a node, which is a specific location in the DOM. When a function such

dwscripts.applySB() is called to make the insertion, the node pointer must pass in as a paramObj parameter.

The user-definable name of this parameter must be specified by the

nodeParamName attribute (see

“nodeParamName” on page 268).

In summary, if your location includes the word node, make sure that you declare the nodeParamName tag.

• The replaceNode value replaces a node with the text.

• The afterNode value inserts the text after a node.

• The firstChildOfNode value inserts the text as the first child of a block tag; for example, if you want to insert

something at the beginning of a

FORM tag.

• lastChildOfNode inserts the text as the last child of a block tag; for example, if you want to insert code at the end of

FORM tag, which is useful for adding hidden form fields.

• nodeAttribute[+attribute] sets an attribute of a tag node. If the attribute does not already exist, this value creates it.

For example, use <insert location="nodeAttribute+ACTION" nodeParamName="form"> to set the ACTION

attribute of a form. This variation changes the user’s

FORM tag from <form> to <form action="myText">.

If you do not specify an attribute, the nodeAttribute location causes the text to be added directly to the open tag. For

example, use

insert location="nodeAttribute" to add an optional attribute to a tag. This can be used to

change a user’s

INPUT tag from <input type="checkbox"> to <input type="checkbox"

<%if(foo)Reponse.Write("CHECKED")%>>.

Note: For the location="nodeAttribute" attribute value, the last search pattern determines where the attribute starts

and ends. Make sure that the last pattern finds the entire statement.
