How to hide infoWindow while using measure tool?

[AlexGilvarry]

In my Javascript API Web application I'm using the infoWindow to query a parcel layer and display display information in a popup when I click the parcel. I've set this functionality to turn on and off depending on if the parcel is visible, and I control the visibility of my different layers with check boxes in a legend.

Every time the parcel layer is checked on of off it calls the clickConnect function with a value of true or false. Depending on this, click connect will call the executeIdentifyTask function, which query's the parcel layer, when clicked, and displays the info in a popup. This works great unless I try to use the esri.dijit.Measurement tool while the parcel layer is turned on. In which case i still get a pop up every time I click, which gets in the way of me measuring parcels.

Is there a way that I could turn the popup/query functionality off while I'm using the measure tool and the parcel layer is turned on? I'm a bit of a beginner at using javascript/dojo so I'm not sure how to do this.
 
Any help would be greatly appreciated! I hope I was clear in my explanation, if not let me know!

Javascript from my map app relevant to the question:

      var app = {};       app.map = null;         var legendLayers = [];       var clickHandler;        function init() {        //add popup         var popup = new esri.dijit.Popup({           fillSymbol: new esri.symbol.SimpleFillSymbol(esri.symbol.SimpleFillSymbol.STYLE_SOLID, new esri.symbol.SimpleLineSymbol(esri.symbol.SimpleLineSymbol.STYLE_SOLID, new dojo.Color([255,0,0]), 2), new dojo.Color([255,255,0,0.25]))         }, dojo.create("div"));

[JianHuang · Accepted solution]

Try this:

dojo.connect(measurement.area, "onClick", function(){      if (this.checked) {        console.log("I'm checked");        dojo.disconnect(yourClickHandler);      }         });

This is great, thanks! but how would I go about turning the popups back on when I'm finished using that tool? I tried messing with it   for a while to make that work, but I couldn't make anything work. Apparently dojo only registers the "onClick" when you're turning the measurement tool on, not when you click to turn it back off.

[AlexGilvarry]

Thank you! After messing around with this for a little bit everything made sense and I got it working.

Hi There -

Luckily I saw this post because I had the exact same issue... I just wanted to clarify that the "dojo.connect(measurement.area, ..." solution mentioned by Jian above works when placed inside the "dojo.connect(map,....." command.

For example......

dojo.connect(map, "onLoad", function(map){
          var measurement = new esri.dijit.Measurement({map: map}, dojo.byId('measurementDiv'));
          measurement.startup();
          measurement.hideTool("area");

          dojo.connect(measurement.distance, "onClick", function(){
     if (this.checked) {
       console.log("Distance Tool was activated");
              map.graphics.disableMouseEvents();
     }
           });
          dojo.connect(measurement, "onMeasureEnd", function(activeTool,geometry){
                    this.setTool(activeTool, false);
                    setTimeout(function() { measurement.clearResult(); }, 3000);
                    map.graphics.enableMouseEvents();
          });
   });


Thanks.

Thank you both, I see what these do conceptually. Unfortunately I tried both ways, neither work in 3.3.

So, for my site I'd used sample code here to use Identify Task on my layer where it loops through and identifies everything. http://jsfiddle.net/URpaW/ Also I called my measurement object 'measurement' as you all did above.

It pops up always, after clicking measurement tools.

First I tried M. Knapp's method of disabling mouse events. While console messages fired, it didn't work. I checked the API Reference and noticed there isn't even a enableMouseEvents or disableMouseEvents  in map.graphics! Or perhaps it is there but I did not see it. The API page needs a more robust Search.

I then tried Jian's idea -- disabling the handler (doIdentify  for onClick of map  which stores the Identify logic). Also added connect to put it back after Measurement was stopped.

I got a message saying Dojo.js did not support removing the object. Console messages again fired successfully but this did not work either. 😕

Thoughts?

I will continue working on this and update...

[KevinMacLeod1]

I tried both ways and they did not work, but I figured it out with a way similar to  Jian's ...

Note that I had to have measurement be at the bottom of our production code. I've seen this before. Weird errors can happen when the measurement dijit instantatiation code for the measurement object is above code for certain other widgets. Hope this gets fixed eventually as it is a confusing issue as the errors don't really lead you to this conclusion and it is not documented as something that needs to be done in the API.

I'm in the same situation and I want to be able to measure on top of a feature layer. Anyone knows how would you be able to do this on AMD?

 var measurement;

  //set the popup's popupWindow property to false. This prevents the popup from displaying
  map.infoWindow.set("popupWindow", false);

Updated with the code. Im new to javascript and new to code so Im still trying to figure this out. It took me a few weeks to get at this point and the Web app is almost done just need this to figure out. I tried adding another button that would disableMouseEvents but that didnt work out. I also looked at the measure widget options but couldnt figure those out.

Thanks in advance.
