Deleting Features using a delete button for multiple feature layers

IanPeebles — Tue, 01 Oct 2013 19:49:31 GMT

I have a simple application set up where the user must use a button to activate delete features. If the button is checked, the user can left click on the feature and delete. If the button is unchecked, the user cannot delete features using the left mouse click. The problem is, that I have multiple feature layers within the application and I want to be able to delete features from each feature layer. Currently, I can only delete from one feature layer.

How can I delete features from each feature layer using the same button?

Here is my current application code:

Try to change:

// DELETE TOOL
function EditingDeleteFeature(results) {
 var deleteFeatureslLayer = results[0].layer;
 var layers = dojo.map(results, function (result) {
  return result.layer;
 });

 // Ctrl+click to delete features and add this delete operation to undomanager
 dojo.connect(deleteFeatureslLayer, "onClick", function (evt) {
  dojo.stopEvent(evt);

  // DELETE FEATURE IS DELETE BUTTON IS CHECKED (ACTIVE)
  if (dijit.byId("tool_delete").checked) {
   deleteFeatureslLayer.applyEdits(null, null, [evt.graphic], function () {
       operation = new esri.dijit.editing.Delete({
                            featureLayer: deleteFeatureslLayer,
                            deletedGraphics: [evt.graphic]
     });
   });
  }
 });
}

To:

// DELETE TOOL
function EditingDeleteFeature(results) {
    var layers = dojo.map(results, function (result) {
        return result.layer;
    });

    // Ctrl+click to delete features and add this delete operation to undomanager
    dojo.forEach(layers, function (deleteFeatureslLayer) {
 dojo.connect(deleteFeatureslLayer, "onClick", function (evt) {
        dojo.stopEvent(evt);

        // DELETE FEATURE IS DELETE BUTTON IS CHECKED (ACTIVE)
        if (dijit.byId("tool_delete").checked) {
            deleteFeatureslLayer.applyEdits(null, null, [evt.graphic], function () {
              operation = new esri.dijit.editing.Delete({
                    featureLayer: deleteFeatureslLayer,
                    deletedGraphics: [evt.graphic]
  });
            });
 }
    });
};

}

  });
            });
 }
    });
};

}

Tried to incorporate your code changes, but I found that the following lines break the application (see bold code):

// DELETE TOOL
function EditingDeleteFeature(results) {
    var layers = dojo.map(results, function (result) {
        return result.layer;
    });

    // Ctrl+click to delete features and add this delete operation to undomanager
    dojo.forEach(layers, function (deleteFeatureslLayer) {
 dojo.connect(deleteFeatureslLayer, "onClick", function (evt) {
        dojo.stopEvent(evt);

        // DELETE FEATURE IS DELETE BUTTON IS CHECKED (ACTIVE)
        if (dijit.byId("tool_delete").checked) {
            deleteFeatureslLayer.applyEdits(null, null, [evt.graphic], function () {
              operation = new esri.dijit.editing.Delete({
                    featureLayer: deleteFeatureslLayer,
                    deletedGraphics: [evt.graphic]
  });
            });
 }
    });
};

Here is an updated code block. I have commented out the dojo.forEach line. and the replaced the }; with a regular }. The functionality is still broken. Here is the code I am working with:

I think I figured out the problem. As it turns out, I had a ) missing in the code block. I can now delete from two feature layers. Here is the updated code block:

// DELETE TOOL function EditingDeleteFeature(results) {     var layers = dojo.map(results, function (result) {         return result.layer;     });      // Ctrl+click to delete features and add this delete operation to undomanager     dojo.forEach(layers, function (deleteFeatureslLayer) {   dojo.connect(deleteFeatureslLayer, "onClick", function (evt) {         dojo.stopEvent(evt);          // DELETE FEATURE IS DELETE BUTTON IS CHECKED (ACTIVE)         if (dijit.byId("tool_delete").checked) {             deleteFeatureslLayer.applyEdits(null, null, [evt.graphic], function () {               operation = new esri.dijit.editing.Delete({                     featureLayer: deleteFeatureslLayer,                     deletedGraphics: [evt.graphic]      });     });    }   });  }); }

zj_zou, Thanks for your assistance.
