424 Server Models

The Server Model API functions

This section describes the functions that configure server models for Dreamweaver.

canRecognizeDocument()

Availability

Dreamweaver MX.

Description

When opening a document (and when more than one server model claims a file extension),

Dreamweaver calls this function for each of the extension-associated server models to see

whether any of the functions can identify whether the document is its file. If more than one

server model claims the file extension, Dreamweaver gives priority to the server model that

returns the highest integer.

Arguments

dom

■ The dom argument is the Macromedia document object, which is returned by the

dreamweaver.getDocumentDOM() function.

Returns

Dreamweaver expects an integer that indicates the priority that you give to the server model

for the file extension. This function should return a value of

-1 if the server model does not

claim the file extension; otherwise, this function should return a value greater than zero.

Example

In the following example, if the user opens a JavaScript document for the current server

model, the sample code returns a value of

2. This value lets the current server model take

precedence over the Dreamweaver default server model.

var retVal = -1;

var langRE = /@\s*language\s*=\s*(\"|\')?javascript(\"|\')?/i;

// Search for the string language="javascript"

var oHTML = dom.documentElement.outerHTML;

if (oHTML.search(langRE) > -1)

retVal = 2;

return retVal;

NOTE

All Dreamweaver-defined server models return a value of 1, so third-party server models

can override the file-extension association.
