Using a standard button to trigger a locator / script

MatthewBaker2

All,

I'm trying to figure out how to use a standard button component to trigger a locator rather than a DOJO component

I was given a hint to try

on(dom.byId("buttonID"), "click", locate);

...but I can't get that to work.

UPDATE: I've attached some code with the suggestion by jskinner-esristaff‌ from comments below - solution is working great. Thank you!!!

Thanks!

Hi Matthew,

Your code is correct, you will just need to reference the "dojo/on" module. Ex:

require([
      "esri/map", "esri/tasks/locator", "esri/graphic",
      "esri/InfoTemplate", "esri/symbols/SimpleMarkerSymbol",
      "esri/symbols/Font", "esri/symbols/TextSymbol",
      "dojo/_base/array", "esri/Color",
      "dojo/number", "dojo/parser", "dojo/dom", "dijit/registry", "dojo/on",

      "dijit/form/Button", "dijit/form/Textarea",
      "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"
    ],
function (
  Map, Locator, Graphic,
  InfoTemplate, SimpleMarkerSymbol,
  Font, TextSymbol,
  arrayUtils, Color,
  number, parser, dom, registry, on)

hey matthew,

please consider marking Jake's reply as the 'answer' to this thread when you have a minute.

Looks like there were a couple of errors.

1. In you 'outFields' parameter, the field needs to have quotes, i.e. "grades"

2. I would recommend using map.centerAndZoom to zoom to the results

One thing I'm not sure is how to call the zoomTo function from the table. You may want to start a new thread for this.

Here is the code I was able to get to work:

I'm sorry, I got my samples mixed up and added that by mistake...

jskinner-esristaff‌ your solution worked great. Thank you!

and thanks timw1984dev‌ for pointing this out!

TimWitt2

Matt,

there is an issue in your locate function. The following error pops-up:

Uncaught ReferenceError: grade is not defined

when I remove your

outfield: [grade]

it seems to work.

MatthewBaker2

Jake Skinner‌, I've added the code I'm working with - also adding what you've suggested, but still no luck.

Hi Matthew,

Your code is correct, you will just need to reference the "dojo/on" module. Ex:

      "dijit/form/Button", "dijit/form/Textarea",
      "dijit/layout/BorderContainer", "dijit/layout/ContentPane", "dojo/domReady!"
    ],
