Issue with draw toolbar activation

[Abdul_AzizMuhammad_Abdul_Majid]

Hi,

I am having issue with the toolbar activation at the line 12 in the below code

toolbar.activate(Draw[tool]);‍‍

I am getting this error when checking the web console:

Uncaught TypeError: toolbar.activate is not a function

After further looking/debugging into the developer tool, it seems that the activateTool() function is calling before the createToolbar().

Below is my code sample

map.on('load', createToolbar);

function createToolbar(themap) {
    toolbar = new Draw(map);
    toolbar.on("draw-end", addToMap);
}‍‍‍‍‍‍
on(dom.byId("point"), "click", activateTool('point'));
on(dom.byId("polyline"), "click", activateTool('polyline'));

function activateTool(toolName) {
    var tool = toolName.toUpperCase().replace(/ /g, "_");
    toolbar.activate(Draw[tool]);
    map.hideZoomSlider();
}

function addToMap(evt) {
    var symbol;
    toolbar.deactivate();
    map.showZoomSlider();
    switch (evt.geometry.type) {
        case "point":
        case "multipoint":
            symbol = new SimpleMarkerSymbol();
            break;
        case "polyline":
            symbol = new SimpleLineSymbol();
            break;
        default:
            symbol = new SimpleFillSymbol();
            break;
    }
    var graphic = new Graphic(evt.geometry, symbol);
    map.graphics.add(graphic);
}‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Thanks to those that can help and thanks to those that helped with the previous question.

Abdul,

  What does your codes require array and vars look like (the beginning of your code)?

Hello Abdul,

As Robert asked, I am also not sure about why you are using a list on line 12 for Draw. However, playing with the sample code from the ArcGIS API for JavaScript Sandbox I was able to get something that I think is what you are looking for. Below is the edited code from the sandbox. It is different from yours in structure but accomplishes the same thing:

map.on("load", createToolbar);

        //---Define your symbols as needed (marker symbol, lineSymbol, fillSymbol)---//

        function createToolbar() {
          toolbar = new Draw(map);
          toolbar.on("draw-end", addGraphic);

          // event delegation so a click handler is not
          // needed for each individual button
          on(dom.byId("buttons"), "click", function(evt) {
            if ( evt.target.id === "buttons" ) {
              return;
            }
            var tool = evt.target.id.toLowerCase();
            map.hideZoomSlider();
            toolbar.activate(tool);
          });
        }

        function addGraphic(evt) {
          //deactivate the toolbar and clear existing graphics 
          toolbar.deactivate(); 
          map.showZoomSlider();

          // figure out which symbol to use
          var symbol;
          if ( evt.geometry.type === "point" || evt.geometry.type === "multipoint") {
            symbol = markerSymbol;
          } else if ( evt.geometry.type === "line" || evt.geometry.type === "polyline") {
            symbol = lineSymbol;
          }
          else {
            symbol = fillSymbol;
          }

          map.graphics.add(new Graphic(evt.geometry, symbol));
        }
      });‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Below is what the HTML might look like:

<div id="buttons">
      <div>Select a shape then draw on map to add graphic</div>
      <button id="Point">Point</button>
      <button id="Polyline">Polyline</button>
 </div>‍‍‍‍‍

I hope it helps!

hi, this is easy, instead of using the default sample given by esri.

on(dom.byId("buttons"), "click", function (evt) {
map.on("click", function (evt) {
console.log(tool);
var pointCordinates = webMercatorUtils.webMercatorToGeographic(evt.mapPoint);
console.log(pointCordinates);
})

I have challenge of saving the coordinates into database, for point I have taken like this.  But how to take the coordinates for polyline.
