QueryTask On Style event listener

GordonBooth — Tue, 01 Oct 2013 17:16:53 GMT

I would like to update the following code to On Style event listener:

 dojo.connect(queryTask, "onComplete", function (fset) {

From what I've read it might be something like this:

queryTask.on("complete", function (fset) {
or
queryTask.on("execute-complete", function (fset) {

They don't work. I was able to get the buffer complete working:

gsvc.on("buffer-complete", function (result) {

Thanks for your help.

I've seen people use the following:

var qt = new QueryTask(url);
var query = new Query();
query.where = "1=1";
query.returnGeometry = false;
query.outFields = outFieldsArr;
qt.execute(query, function (results) {
 console.log("results:", results);
 //do something else
});

Although this isn't using the on event specifically, it may help.

Thanks for the reply however, I would like to update the existing code to On Style event listener. Anybody?

var qt = new QueryTask(url);
var query = new Query();
query.where = "1=1";
query.returnGeometry = false;
query.outFields = outFieldsArr;
qt.execute(query, function (results) {
 console.log("results:", results);
 //do something else
});

on(qt, "complete", function(results){
 console.log('test');
});

The above worked for me.

If your app is failing silently and events aren't being triggered, use a try/catch block to identify at what point your code fails.
