(migrating thread from the Tapestry users list)
Thanks Andreas!
That helped a lot -- needed to make sure implementing those functions
was going to get me further.
I added the following implementations of buildEventProperties,
buildTargetProperties, and buildNodeProperties inside tapestry.event = {
... }
/**
* Function: buildEventProperties
*
* Takes an incoming browser generated event (like key/mouse events) and
* creates a js object holding the basic values of the event in
order for
* it to be submitted to the server.
*
* Parameters:
*
* event - The javascript event method is based on, if it isn't a valid
* browser event it will be ignored.
* props - The existing property object to set the values on, if it
doesn't
* exist one will be created.
* args - The arguments from an method-call interception
* Returns:
*
* The desired event properties bound to an object. Ie
obj.target,obj.charCode, etc..
*/
buildEventProperties:function(event, props, args){
if (!props) props={};
var isEvent = (typeof event != "undefined")
&& (event)
&& (typeof Event != "undefined") && (event.eventPhase);
if (isEvent) {
if(event["type"]) props.beventtype=event.type;
if(event["keys"]) props.beventkeys=event.keys;
if(event["charCode"]) props.beventcharCode=event.charCode;
if(event["pageX"]) props.beventpageX=event.pageX;
if(event["pageY"]) props.beventpageY=event.pageY;
if(event["layerX"]) props.beventlayerX=event.layerX;
if(event["layerY"]) props.beventlayerY=event.layerY;
if (event["target"]) this.buildTargetProperties(props,
event.target);
}
props.methodArguments = dojo.toJson( args );
return props;
},
/**
* Function: buildTargetProperties
*
* Generic function to build a properties object populated with
* relevent target data.
*
* Parameters:
*
* props - The object that event properties are being set on to
return to
* the server.
* target - The javscript Event.target object that the original
event was targeted for.
*
* Returns:
* The original props object passed in, populated with any data found.
*/
buildTargetProperties:function(props, target){
if(!target) { return; }
var isNode = target.nodeType && target.cloneNode;
if (isNode) {
return this.buildNodeProperties(props, target);
} else {
dojo.raise("buildTargetProperties() Unknown target type:" +
target);
}
},
/**
* Function: buildNodeProperties
*
* Builds needed target node properties, like the node's id.
*
* Parameters:
* props - The object that event properties are being set on to
return to
* the server.
* node - The dom node specified as the Event.target in a
javascript event.
*/
buildNodeProperties:function(props, node) {
if (node.getAttribute("id")) {
props["beventtarget.id"]=node.getAttribute("id");
}
},
I just copied over the implementations from Tap 4.1.5's core.js, and:
1. replaced dojo.event.browser.isEvent(event) with an inline
implementation
2. replaced dojo.dom.isNode(target) with an inline implementation
3. changed dojo.json.serialize( args ) to dojo.toJson ( args )
This got my simple test case going of an in-page button
triggering-via-AJAX an @EventListener in the backing page.
Thanks!
