Pass Search Parameter in URL

mpboyle

I have downloaded and placed an app built with the web app builder beta 3 on our web server. The app works fine, but I have been asked if it's possible to pass a search parameter in the URL...something like http://gis.linncounty.org.../?gpn=1234567890 ... where the app would zoom to the parcel with an id of 1234567890.

I don't know much of anything about JavaScript so I was wondering if this is possible, and if so, what it would take to implement?

Thanks!

Hi Robert,

I am having an issue where the search url does not immediately zoom to the result(s) like your demo (ArcGIS Web Application). I am using the export url to zoom specifically to a grave site. The url works opening the application and then nothing. It does not display that a site was passed into it, until I click the widget. I have a attached my settings. Did I miss something? Does it not like custom map titles/projections?

Settings for ESearch for URL export

MiriEshel

Hi Robert,

Thank you for your answer but I think I was not understood...

I want to ask about two fields: field1 = 'something' AND field2 = 'something else' (without definition expression) and be able to use it in URL.

I see in the code that it takes only the last value:

for(var s=0; s<content.length; s++){

eVal = content.value.toString();

}

It does not concatenate the conditions, eVal takes only the last one.

As for now, I guess your widget does not support it.

Thanks again,

Miri

Miri,

Sure the URL Search parameters are exactly the same of the old Flex Version. Live sample of this in action can be found here:

Hi Robert,

I looked at your live demo: ArcGIS Web Application. It looks pretty nice ans impressive. I also saw the URL Search capabilty.

I wanted to ask if it can make the URL search on two fields. When I looked at Louisville Zoning layer, I saw there are 2 parameters for the search: Zoning type & Zoning name. I asked for Zoning type = RESIDENTIAL and Zoning name = RES MULTI-FAMILY (see attached file) but when I Exported the Search URL, I saw only reference to Zoning name : http://gis.calhouncounty.org/WAB/V1.1.1/widgets/eSearch/index.html?esearch=RES MULTI-FAMILY&slayer=0&exprnum=0

Is it possible to search by 2 fields in the URL?

Thanks,

Miri

thanks for clarifying.

I realize all this takes time and care. I love what you are doing.

I also am wondering about this:

the default esri query tool retains the different queries. this is nice as I can then do more than one selection and see the results in the attributes lists

it appears that your tool presently clears the previous query when a new one is run.

is there a switch somewhere that can be set to retain the queries until manually cleared?

Glenn,

I don't have any current plans to implement my widget the same way the Query widget handles this. What you can expect is I will be working on getting the same features that my Flex version of the eSearch. So that version gave you the ability to specify symbology for individual search layers and that will be coming for this eSearch.

The definition expression is something I though I had finished. But now looking in the code I forgot to implement it. So it is a coming feature.

Robert,

this is wonderful. thank you again.

I love the unique dropdowns and the predefined dropdowns.

I do have three questions-

in the default esri query when the expression is configured there is a 'results tab' where it is possible to set the symbol specific to that query. are you planning on adding that feature?

and

you have box called 'definition expression'

I am unclear about what this box is for. it doesn't seem to be required.

I am hoping it is something you are working on that will provide a 'definition query' like capacity, but maybe it is just a label of some sort.

All,

My Enhanced Search widget with URL search and MORE is now available (live preview site also available). The widget feature help documentation (just like all the esri widget do). Check it out here: Enhanced Search Widget Beta 3.2

Hi Matthew,

In addition to the widget listed above take a look through the following Javascript sample:

History API to track selected feature | ArcGIS API for JavaScript

This sample touches on the classes in the api that would help support the functionality you are looking for.

One of the main goals is to see how you can utilize the history api, but it runs off of a query string in the url which is what you are looking for.

To provide that functionality the api supports the following class:

https://developers.arcgis.com/javascript/jsapi/esri.urlutils-amd.html

this class supports a url to object function that is used in the sample here:

//extract the parcel id from the url
        function getParcelFromUrl(url) {
          var urlObject = urlUtils.urlToObject(url);
          if (urlObject.query && urlObject.query.parcelid) {
            return urlObject.query.parcelid;
          } else {
            return null;
          }
        }

The orange line I highlighted above is the where the parcel ID is obtained in the application.

Later in the application that obtained ID is used to select the required features:

function selectParcel(parcelid) {
if (parcelid) {
var query = new Query();

when that sample runs you pass in a url to the application with the id of the parcel you want to zoom to:

http://developers.arcgis.com/javascript/samples/exp_history/?parcelid=1920352007

Hope this helps as to the background of that can be obtained and used.

Jeff

Do you add the widget after download or add the widget through the Web AppBuilder developer mode...configure and then download?

RobertScheitlin__GISP

Matt,

Sure find it here Enhanced Search Widget Beta 3
No it is custom code in my widget (to be released soon).

mpboyle

Robert,

A couple questions:

1) Is your Enhanced Search Widget for WAB available for download or implementation into WAB?

2) Is it possible to call an existing widget within the URL, like the Filter/Query widget and pass the search?

RobertScheitlin__GISP

Matthew,

This will be part of the next beta release of my Enhanced Search Widget for WAB. It is possible but quite involved.
