Question

How to pass the control from InDesign to Bridge? (JS)

My purpose is to execute InDesign script and pass the control to Bridge and execute it´s script and then get the control back to InDesign. The #target "bridge" directive is not enough. I am looking similar to "tell application "xxx" " in AS where you can easily jump between applications.

When I am running the following lines I am getting error as I think I am still talking to InDesign instead of Bridge. The error is pointing to line after the #target "bridge" directive.

My InDesign CS2 script "ExecuteBridge.jsx" contains just following line:

app.doScript( File("Macintosh HD:ChangeColorOfLabel.jsx"))

and the file "ChangeColorOfLabel.jsx" contains the following (this works well if driven in ExtendScript editor, but gives error when saved as file to be executed):
#target "bridge"
var sels = app.document.selections;
for (var i = 0; i < sels.length; i++)
{
var thumb = sels;
var md = thumb.metadata
md.namespace = "http://ns.adobe.com/xap/1.0/";
md.Label = "Green";
}

I would be very pleased if someone could give a small sample how to pass control from one application to another using JS.

regards

I found myself a good example for my question from the Bridge scripting reference!

Here it is also for other scripters:

var targetApp = BridgeTalk.getSpecifier( "bridge", "1");
if( targetApp ) {
// construct and send message
}
var bt = new BridgeTalk; // create a new BridgeTalk message object
bt.target = "bridge"; // send this message to the Bridge application
// the script to evaluate is contained in a string in the "body" property
bt.body = "app.browseTo(Folder('Macintosh HD:Images:')); app.document.target.children.length;"
bt.onResult = function(returnBtObj)
{ processResult(returnBtObj.body); }
bt.send();

-------

It works well.

Hi,

You could use a BridgeTalk message to pass a script from InDesign to Bridge. Something like:

var myScript = "var sels = app.document.selections;";
myScript += "for (var i = 0; i < sels.length; i++) { ";
myScript += "var thumb = sels;";
myScript += "var md = thumb.metadata;";
myScript += "md.namespace = 'http://ns.adobe.com/xap/1.0/';"
myScript += "md.Label = 'Green';}";

var bt = new BridgeTalk();
bt.target = "bridge";

bt.body = myScript;

bt.send();

Hope it helps,
