How to customize a map tool so as to be able to add a shapefile then create an object and zoom to it?

 

We tried to customize a map tool so as to be able to add a shapefile then create an object and zoom to it to use this tool in the cityworks map and zoom to it, but seems that we missing something, I highly appreciate if someone can have a look on this:

define(["dojo/dom", "dojo/json", "dojo/on", "dojo/parser", "dojo/sniff", "dojo/_base/array", "esri/Color", "dojo/domReady!", "esri/config", "esri/InfoTemplate",
       "esri/request", "esri/geometry/scaleUtils", "esri/layers/FeatureLayer", "esri/renderers/SimpleRenderer", "esri/symbols/PictureMarkerSymbol", "esri/symbols/SimpleFillSymbol", "esri/symbols/SimpleLineSymbol"    
      ],
        function (
        esriConfig, InfoTemplate, Map, request, scaleUtils, FeatureLayer,
        SimpleRenderer, PictureMarkerSymbol, SimpleFillSymbol, SimpleLineSymbol,
        dom, JSON, on, parser, sniff, arrayUtils, Color, lang
      ) {

          parser.parse();

          var portalUrl = "https://www.arcgis.com";

          esriConfig.defaults.io.proxyUrl = "/proxy/";

          on(dom.byId("uploadForm"), "change", function (event) {
            var fileName = event.target.value.toLowerCase();

            if (sniff("ie")) { //filename is full path in IE so extract the file name
              var arr = fileName.split("\\");
              fileName = arr[arr.length - 1];
            }
            if (fileName.indexOf(".zip") !== -1) {//is file a zip - if not notify user
              generateFeatureCollection(fileName);
            }
            else {
              dom.byId('upload-status').innerHTML = '<p style="color:red">Add shapefile as .zip file</p>';
            }

            switch (layer.geometryType) {
              case 'esriGeometryPoint':

        this.show = function() {

                initialized = true;

                displayPanel = proxy.layout.createTrailingPanel(uiConfig);
                selectChild();
            } else {
                //The UI is already created so just show it
                selectChild();
            }
        };
        
	});
 

It should be written the same way as shown in the attached file (the attached file is how to add xy to cityworks map, and it works perfectly)

Highly appreciate your effort.

Thank you in advance

Thank you Egge for your reply, yes I used the code here, but I want to edit it to match the one attached in order to work with our Cityworks map, Do you have any idea what is the best practice to do this? I tried to edit it but ends with an error, and unfortunately I do not have enough experince in javascript.

Thank you in advance

Hi Majdoleen Awadallah,

Yeah, the idea would be to start with a working example of the new functionality you want to add to an existing application. That example is provided by Esri.

Now the next step is to integrate this functionality in your existing cityworks application. And this requires - apart from a lot of trial and error - at least some experience with JavaScript and the ArcGIS API for JavaScript 3.x.

You indicate you are missing 'something'. But what exactly ae you missing? Did you already manage to create the dialog to select and add the shapefile? Does the shapefile appear in the wrong location? What error messages do you get?

This would really require someone to go and sit down to accomplish this.

Did you contact Cityworks? Are they able to help?

BR,

Thank you Egge for your advice, I am not sure if the dialog that select and add the shapefile is working fine, when I tried to add the js tool thats written above, the toolbar is stopped working, may you please have a look on the above js code? or may you please advice me how to check my code if it is written correctly? software? tool?...
