and you can also provide a method do your component/page java class, say String getPointsJsArray()
and provide it as input-symbol to your script. kiuma On 1/29/07, Matt Brock <[EMAIL PROTECTED]> wrote:

It works much like the FOREACH component. So, for example: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE script PUBLIC "-//Apache Software Foundation//Tapestry Script Specification 3.0//EN" "http://jakarta.apache.org/tapestry/dtd/Script_3_0.dtd";> <script> <input-symbol key="pointsArray" class="java.util.ArrayList" required="yes"/> <body> var Points = { elements: [], pointsObj: function(latitude, longitude) { this.latitude = latitude; this.longitude = longitude; }, add: function(id, latitude, longitude) { Points.elements[id] = new Points.pointsObj(latitude, longitude); }, remove: function(id) { delete Points.elements[id]; } }; </body> <initialization> <foreach expression="pointsArray" key="keyPoint"> Points.add(${keyPoint.id},${keyPoint.latitude},${keyPoint.longitude }); </foreach> </initialization> </script> The body is just creating a simple JavaScript object to hold your points for easy access, plus a couple of convenience methods. The real meat is in the initialization part. -- View this message in context: http://www.nabble.com/Passing-Array-to-JavaScript---tf3122349.html#a8684293 Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
