A simple data source example 387

var params = extPart.findInString("MyDatasource_DataRef",

expression);

if (params)

{

retArray[0] = params.sourceName;

retArray[1] = params.bindingName;

}

return retArray;

}

function deleteDynamicSource(sourceName, bindingName)

{

var siteURL = dw.getSiteRoot();

if (siteURL.length)

{

//For localized object name

if (sourceName != "MyDatasource")

{

sourceName = "MyDatasource";

}

dwscripts.deleteListValueFromNote(siteURL, sourceName, bindingName);

}

Save this file MyDatasource.js in the Configuration/DataSources/ColdFusion.

Creating the supporting command files for user input

The addDynamicSource() function contains the command

dw.popupCommand("MyDatasrouce_Variable"), which opens a dialog box for the user to

enter a specific variable name. However, you still need to create the dialog box for

MyDatasource Variable.

To provide a dialog box for the user, you must create a new set of command files: a command

definition file in HTML and a command implementation file in JavaScript (for more

information about command files, see “How commands work” on page 167).

The command definition file tells Dreamweaver the location of the supporting

implementation JavaScript files as well as the form for the dialog box that the user sees. The

supporting JavaScript file determines the buttons for the dialog box and how to assign the

user input from the dialog box.
