Hi,

I'm trying to execute a geoprocessing service via a link in the popup as shown in this sample ArcGIS API for JavaScript Sandbox. Which file do I need to modify in an app built using WAB developer edition to have an additional link shown up in the popup? And is there a way to make the popup stick after the gp service has been successfully run? In the sample, the result flashes on for a few seconds and then disappears.

Any pointers will be greatly appreciated!

Thank you,

Lesi

Lesi,

   The best place is in the jimu/PopupManager.js file (lines 24 -38):

      _createPopupMenuButton: function(){
        if(this.popupMenuButtonDesktop) {
          html.destroy(this.popupMenuButtonDesktop);
        }
        if(this.popupMenuButtonMobile) {
          html.destroy(this.popupMenuButtonMobile);
        }
        this.popupMenuButtonDesktop = html.create('span', {
          'class': 'popup-menu-button'
        }, query(".actionList", this.popupUnion.bigScreen.domNode)[0]);

        var mobileActionListNode =
          query("div.esriMobileInfoView.esriMobilePopupInfoView .esriMobileInfoViewItem").parent()[0];
        var mobileViewItem = html.create('div', {
            'class': 'esriMobileInfoViewItem'
          }, mobileActionListNode);
        this.popupMenuButtonMobile = html.create('span', {
          'class': 'popup-menu-button'
        }, mobileViewItem);

        on(this.popupMenuButtonMobile, 'click', lang.hitch(this, this._onPopupMenuButtonClick));
        on(this.popupMenuButtonDesktop, 'click', lang.hitch(this, this._onPopupMenuButtonClick));

        var link = html.create("a",{
          "class": "action",
          "id": "statsLink",
          "innerHTML": "Population", //text that appears in the popup for the link
          "href": "javascript: void(0);"
        }, query(".actionList", this.popupUnion.bigScreen.domNode)[0]);


        //when the link is clicked register a function that will run
        on(link, "click", this.calculatePopulation);
      },

      calculatePopulation: function(){

      },

Be advised that you will have to do more coding to handle mobile popups though.

Hi Robert! I'm relatively new to JavaScript and have a follow-up question. The sample code uses window.map.infoWindow.getSelectedFeature() to get a hold on the selected feature. I tried to use window.map.popupUnion.bigScreen.selectedFeature() in the calculatePopulation function but I got an error message saying "Cannot read property 'bigScreen' of undefined". How can I achieve something similar as in the sample code?

Lesi,

  It would be:

this.popupUnion.bigScreen.selectedFeature();

Thank you for the quick reply, Robert!

I pasted your line in and got an error of "Cannot read property 'bigScreen' of undefined at HTMLAnchorElement.calculatePopulation". Any idea? 

Thank you for your help!

Lesi,

   Sounds like your function you are calling is in a different scope then. You need to use lang.hitch.

Hi Robert! Sorry for keep bugging you. I made the changes in popupManager.js and would like to have the new link displayed in your popup panel widget. How should I go about that? 

Thank you!

Lesi,

   That is a completely different route. You should start a new question for that.
