Buffer, select and export

[laceysanders]

I'm trying to create a buffer at the users input measurement select polys in the buffer and export to a csv. Is there a possible way to do this in one tool? Also, is there a way to get a URL in a field to be a hyperlink in the popup?

Thanks so much,
Lacey

I think you can do this pretty easily if I understand you correctly. I've done something similar in one of my apps by building an esri/InfoTemplate in my viewer.js (config file) and passing that as an attribute of my layer's options param.

First, include the dependency in your viewer config:

define([
    'esri/units',
    'esri/geometry/Extent',
    'esri/config',
    'esri/tasks/GeometryService',
    'esri/layers/ImageParameters',
        'esri/InfoTemplate'
], function (units, Extent, esriConfig, GeometryService, ImageParameters, InfoTemplate) {
...
}

Then build the info template. I do this just below where the imageParameters are set up:

var myInfoTemplate = new InfoTemplate();
    myInfoTemplate.setTitle( 'Info Template With Link' );
    myInfoTemplate.setContent( '<a href="{my_field_with_link}" target="_blank">Open in new window</a>' );

Then assign the info template to your layer. Here's an example for a feature layer:

operationalLayers: [{
            type: 'feature',
            url: 'http://services1.arcgis.com/g2TonOxuRkIqSOFx/arcgis/rest/services/MeetUpHomeTowns/FeatureServer/0',
            title: 'STLJS Meetup Home Towns',
            options: {
                id: 'meetupHometowns',
                opacity: 1.0,
                visible: true,
                outFields: ['*'],
                mode: 0,
                infoTemplate: myInfoTemplate
            },
            editorLayerInfos: {
                disableGeometryUpdate: false
            }
        },

...

If you are using a dynamic layer, you will need to pass as an object with the layer id as the property name

{
            type: 'dynamic',
            url:  'http://sampleserver6.arcgisonline.com/arcgis/rest/services/DamageAssessment/MapServer',
            title: 'Damage Assessment',
            slider: true,
            noLegend: false,
            collapsed: false,
            options: {
                id: 'DamageAssessment',
                opacity: 1.0,
                visible: true,
                                // '1' is the id of the layer in my service I want the info template on.
                imageParameters: { 1: imageParameters }
            },
            layerControlLayerInfos: {
                swipe: true
            }
        }

Hope this helps.

Regarding the hyperlink, issue #212 has a few additional examples on how to create the hyperlink in the infoWindow.

Regarding your first question about buffer/export, there isn't a process for that in version 1.3.0. There is a set of widgets to support this workflow coming soon.

Thank you both for your responses. I will be using those as guides for the URL in the infoWindow. It's exciting to hear that a buffer, select and export tool is in the making, in the meantime is there a way to add only a buffer to app? Thanks again, Lacey
