Parse URL Parameters in Tax Parcel Viewer

RyanKammerer1 — Mon, 23 Jun 2014 23:29:43 GMT

I've configured the Tax Parcel Viewer (10.2) for our City's needs, and now I would like to be able to parse the URL parameter of an attribute when selected. In other words, when a parcel is selected, I would like the parcel ID to be parsed as a parameter in the URL. Similar to this html5 sample viewer: https://developers.arcgis.com/javascript/jssamples/exp_history.html.

The problem is that I can't figure out how the incorporate this feature into the tax parcel viewer application. I believe it needs to be in the locator.js file, and could be accomplished with-

"if (selection.length > 0) {
              var getParcel = selection[0].attributes["APN"];
              //Refresh the URL with the currently selected parcel
              if (typeof history.pushState !== "undefined") {
                window.history.pushState(null, null, "?getParcel=" + selection[0].attributes.APN);
              }
            }"

-but I have had any luck getting this to work. I'm wondering if anyone has attempted the same and maybe had success.

Any help would be much appreciated!

Thank you

Check out this example: http://jsbin.com/hobomode/2

I just added your JavaScript to the selectParcel() function in the ESRI sample:

function selectParcel(parcelid) {
 if (parcelid) {
  var query = new Query();
  query.where = "PARCELID = '" + parcelid + "'";
  var deferred = parcels.selectFeatures(query, FeatureLayer.SELECTION_NEW, function (selection) {
   var center = graphicsUtils.graphicsExtent(selection).getCenter();

   // add parcel to browser history
   var apn = selection[0].attributes.APN;
   if ((typeof history.pushState !== "undefined") && (apn)) {
    window.history.pushState(null, null, "?getParcel=" + apn);
   }

   var extHandler = map.on("extent-change", function () {
    extHandler.remove();
    //zoom to the center then display the popup 
    map.infoWindow.setFeatures(selection);
    map.infoWindow.show(center);
   });
   map.centerAt(center);
  });
 }
}

Hi Owen,

Thanks for your response, I appreciate the help, but I think the example you gave is from the html5 esri example. I'm trying to take the functionality of that sample and incorporate into the JSAPI Tax Parcel Viewer. (http://tryitlive.arcgis.com/TaxParcelViewer/)

I'm hoping someone out there has had better luck with this than I'm having.

Thanks

Ryan

Yeah! I figured it out. In case anyone else is interested, it's actually very, very simple.

First, in the default.htm file, you need to reference the ArcGIS JavaScript 3.9 API using:

<link rel="stylesheet" href="http://js.arcgis.com/3.9/js/esri/css/esri.css">

Then, in the locator.js file, at the function to populate parcel information (about line 606), add this to selectedParcel

selectedParcel = feature.attributes[parcelAttributeID];
//Refresh the URL with the currently selected parcel
              if (typeof history.pushState !== "undefined") {
                window.history.pushState(null, null, "?getParcel=" + selectedParcel);
              }

after that, if everything else is configured, your selected parcel ID should show up as a parameter to the URL.

Wow, it's always much simpler than I think.

Hope this saves someone some time!
