WAB Near Me Widget

Fahad_Dalbouh — Thu, 21 Jul 2016 17:35:13 GMT

Good Afternoon All,

I Have a question about NearMe widge. After, the Near Me Widget reports the list of features within it's buffer distance, I decided to move to another widget, but the buffere and the symbols still floats and I couldn't know how to trurn them off.

Is it possible to control them on the widget configuratio.

Any help is appreciated.

Fathad,

If you are using WAB Developer version than you can add some code to get graphics to hide when the widget is hidden:

onOpen: function () {

if (this._isValidConfig) {

this._onWindowResize();

this._connectMapEventHandler();

}

if(this._highlightGraphicsLayer){

this._highlightGraphicsLayer.show();

}

if(this._bufferGraphicLayer){

this._bufferGraphicLayer.show();

}

onClose: function () {

if (this._isValidConfig) {

this._disconnectMapEventHandler();

}

if(this._highlightGraphicsLayer){

this._highlightGraphicsLayer.hide();

}

if(this._bufferGraphicLayer){

this._bufferGraphicLayer.hide();

}

If you are using the AGOL version then your only option is to click the clear button on the Search dijit inside the NearMe widget UI.

Hello Robert,

Thanks for your early response.I'm actually using the AGOL version. I also didn't find the clear button you mention on the Search dijit inside the NearMe widget.

Does ESRI have plans to update this widget with the code you provide in AGOL version?

Fadhad,

This is the clear button I was talking about.

You should have this in the AGOL Version.

Hello (Robert / Fadhad),

In the AGOL Version - I can clear the results using the X in the search an address or locate on map - however, the X will not clear the graphics/result set on the Map. As a user when I try to work with the original layer (I want to see all available features) I cannot, I can only work with the last results set.

Other than adding the code above to a WAB developer version is the AGOL version going to have a work around soon ??

thank you.

Hello Elisabeth,

You are right, this does not clear the graphics set on the map. I'm not sure if ESRI has planned to update this widget with the code above in AGOL version. I hope they are going to do that soon.

Thank you.

Hi Robert - where are you adding this code? Clearing the search handles the search point graphic visibility but not the buffer. I can't seem it to clear on either a widget panel close or search clear-

Thanks

David

Ah nevermind - found it in the widget.js

Hi Robert et al - fyi in the onClose function I am clearing the bufferGraphicLayer as opposed to hiding:

if(this._bufferGraphicLayer){ //clearthe buffer on widget close
 this._bufferGraphicLayer.clear();
 }‍‍‍

as hiding restors the graphic back in the onOpen bufferGraphicLayer.show method. This way there is nothing to show, which is what I want in my case. It would be nice however if clearing the address search handled clearing the buffer.

David,

so just add that to the _clearResults function then.

Re: WAB Near Me Widget

DavidColey — Fri, 26 Aug 2016 19:05:15 GMT

Oh yes that works, duh. I'm still seeing some funny visibility behavior on result layers if the location result is cleared while the result is selected. If the setting 'Only draw selected layer results' widget option is enabled, and the result is cleared, then only the selected feature from the layer will draw, not all the features.

At this point, users just have to make sure that they do not clear search results with an active selection or they will no longer be able to see the entire layer unless they do a browser refresh. Here you can see I have 2 schools returned

if I clear the result, only the 2 schools will show in any subsequent layer list toggle action unless I redo a search. I guess the widget is not releasing the itemlist?

David,

to fix that you need to add this to the _clearResults function too:

if(this._itemListObject && this._itemListObject._selectedLayer){
  this._itemListObject._resetFilter(this._itemListObject._selectedLayer.layerIndex);
}‍‍‍

junshan_liu-esristaff‌ The Near Me widget seems to have things that are not working properly or just need some more work.

I think the addition of a clear link/button is really needed.

Hi Lindsay,

Could you help have a look?

Re: WAB Near Me Widget

DavidColey — Mon, 29 Aug 2016 13:13:22 GMT

I thought i might be on the right track re itemList, thanks I'll get this tested right away

Re: WAB Near Me Widget

DavidColey — Mon, 29 Aug 2016 15:26:22 GMT

Yes this works as expected, thanks Robert. If I'm following the logic correctly, this reads if the the _itemListObject and the _itemListObject selected layers are not null (not an empty array) then reset the object back to null for every layer at a given index . . .

David,

Ultimately what it does is it removed the layer definition that was applied to the layer when you use the widgets "Only the selected layer in the search results will draw on map"

Re: WAB Near Me Widget

LindsayThomas — Mon, 29 Aug 2016 16:21:52 GMT

Yes, this is an issue in Near Me and we have fixed it. We have added the ability to clear the widget results\graphics in the next release by 1) using the "X" button in the Search dialog and 2) clearning the results\graphics when the widget is closed.

This fix will be available in the Web AppBuilder for ArcGIS in the September 2016 Release and it will be available in the next version of Web AppBuilder (Developer Edition) 2.2 .

Re: WAB Near Me Widget

DavidColey — Mon, 29 Aug 2016 16:22:16 GMT

Ok thanks for that - helps my understanding. I believe I will have to add the snippet the the onClose event for the panel as well in order to handle the interactive cases

Lindsay,

What do you think about adding a simple clear link to the widget that way you can clear the buffer and layers definition query without having to close the widget?
