x	Optional		The X (horizontal) coordinate of the upper-left corner of the message box.ColdFusion ignores this attribute if you do not set the y attribute.
y	Optional		The Y (vertical) coordinate of the upper-left corner of the message box.ColdFusion ignores this attribute if you do not set the x attribute.

Usage

The cfmessagebox creates a message box, but does not show it. You show a message box, say named mymessagebox, in JavaScript code as follows:

ColdFusion.MessageBox.show("mymessagebox");

If you specify a callbackhandler, clicking a button in the message box invokes the callbackhandler by passing the button label as a parameter. For prompt boxes, an additional parameter containing the prompt text is also passed.

For alert and confirm boxes:

var function_name = function(button);

For prompt boxes:

var function_name = function(button, promptmessage);

The EventObject parameter is the JavaScript ID (not the name) of the button that was pressed. The textmessage parameter is a string with the contents of the prompt text box.

Example

The following example has three buttons, one to display each type of message box. The message box labels are customized, and the messagebox callback function displays the type of the clicked button.

//The button onClick handler displays the message boxes. 
function showMB(mbox) { 
ColdFusion.MessageBox.show(mbox);
