I am looking for some sample code to create a custom pop-up for search results. I have found an old thread to override the default search results pop-up, but I would like it to be dynamically populated based on attributes of a intersected features. I thought I had seen something like this before, but for the life of me cannot find it.

For example, let's say I have a census tracts feature layer with basic demographic information. When I enter an address into the search widget textbox, I would like the pop-up box to show these attributes from the feature layer for the census tract that the entered address intersects.

Added bonus, if the custom text box also has the search string, so, for instance, the searched address or coordinates or whatever. E.G. 100 E. Main St. is in Census Tract XX with a Population of X or whatever.

Thanks in advance.

Maybe this will get you going. (Written for 4.x)

      searchWidget.on('select-result', function(evt){
        let query = sections.createQuery();
        query.geometry = evt.result.feature.geometry;
        query.spatialRelationship = 'within';
        query.outFields = ['*'];
        query.returnGeometry = true;
        query.outSpatialReference = view.spatialReference;
        query.maxAllowableOffset = 0;
        sections.queryFeatures(query).then(function(result){
          view.popup.open({
            features: result.features,
            location: result.features[0].geometry.centroid
          });
        });
      });

Hi @ToddFagin, have you seen this sample?

https://developers.arcgis.com/javascript/latest/sample-code/widgets-search-multiplesource/

This sample uses a LayerSearchSource with the Search widget, and opens the pop-up on the featureLayer based on the features' attributes. It does have the caveat that if you're using a layer as the source, the same layer cannot be added to the map. I'm sure there are clever ways to work around this if necessary (e.g. a duplicate layer).

Thank you. I have, indeed, seen this and it is what I am using to search on multiple data sources.

Here's my quandary. Say someone searches on a census tract layer by some value. This isn't a problem--the maps zooms to that tract and the popup appears. However, let's say someone just enters a street address or a lat,lon. The maps will zoom to that location, but there is a default popup with the entered search (e.g. address or lat, lon). I want the popup to show the census tract information at that location. Of course, the user can get it with an additional click, I just want it to be seamless.

I am not actually using census tract data, that was just my example.  I am actually using PLSS data. So, if someone searches by a PLSS layer, say Section-Township-Range (STR), they will be returned with various attributes in a popup associated with that STR. However, they may not know the STR information, but have coordinates and search by that. If so, I want the popup to show the STR attributes associated with that set of coordinates.

Hopefully, that makes sense.

Many thanks.

As I continued to search for a solution to this issue, I came across an older post and a solution by @RobertScheitlin__GISP that does, more or less, what I want. However, it was written for 3.23. I am trying to get it to week with 4.22, though, because it will be part of a larger project that is otherwise functioning well.

In a nutshell, I would like to use the search widget to perform a search and query a feature layer based on the results of this search. For instance, say I have a PLSS layer and when one enters an address or set of coordinates, the PLSS layer is queried at that search location and the pop-up returns the PLSS attributes associated with that location.

I hope to solve this first, but to add a little more complexity to the issue, I am actually searching multiple sources. Searching by multiple layer sources works great when the appropriate search term is entered (e.g. township, range, and section) information, but I essentially want a reverse geocode type solution in which someone types an address or enters coordinates and the PLSS layer is queried at that location and those results are returned.

At issue (among many other things) is I am not particularly savvy when it comes to JS. I can take others' code and modify it to my needs, but that is the extent of it--so I basically need a lot of handhold.

Below is the code I have working that includes everything except the spatial query. The feature layers I am using in it are just place holders  and are not the ones I will actually be using going forward (so the attributes that pop up are a bit nonsensical at the moment).

Maybe this will get you going. (Written for 4.x)

      searchWidget.on('select-result', function(evt){
        let query = sections.createQuery();
        query.geometry = evt.result.feature.geometry;
        query.spatialRelationship = 'within';
        query.outFields = ['*'];
        query.returnGeometry = true;
        query.outSpatialReference = view.spatialReference;
        query.maxAllowableOffset = 0;
        sections.queryFeatures(query).then(function(result){
          view.popup.open({
            features: result.features,
            location: result.features[0].geometry.centroid
          });
        });
      });
