DREAMWEAVER API REFERENCE

Document

Last updated 8/27/2013

Arguments

offsetBegin, offsetEnd

• These arguments are the opening and closing points, respectively, for the new selection, which is expressed as

character offsets into the document’s source code. If the two numbers are the same, the new selection is an insertion

point. If the new selection is not a valid HTML selection, it is expanded to include the characters in the first valid

HTML selection. For example, if offsetBegin and offsetEnd define the range

SRC="myImage.gif" within <IMG

SRC="myImage.gif">, the selection expands to include the entire IMG tag.

Returns

Nothing.

dreamweaver.nodeExists()

Available

Dreamweaver 3.

Description

Determines whether the reference to the specified node is still good. Often when writing extensions, you reference a

node and then perform an operation that deletes it (such as setting the

innerHTML or outerHTML properties of its

parent). This function lets you confirm that the node hasn’t been deleted before you attempt to reference any of its

properties or methods. The referenced node does not need to be in the current document.

Arguments

node

• The node argument is the node that you want to check.

Returns

A Boolean value: true if the node exists; false otherwise.

Example

The following example gets the current node, locates a table within it, and later calls dw.nodeExists() to see if the

original node still exists:

1 2 ... 294 295 296 297 298 299 300 301 302 303 304 ... 532 533
