Hello
I am very new to javascript coding, I had a third party group build a webmap for us. We are in testing phase now and I am trying to learn basics. My layer data is stored in ArcGIS Online as feature service layers and we are using web token to connect to the data map and layers. I was wanting to set up labels for each feature and where to add the code in.
Here is a sample of the connected in the code
{
type: 'feature',
url: 'https:// /FeatureServer/1?token=' + tokenNumber,
title: 'Parcels',
options: {
id: 'Parcels',
opacity: 1.0,
visible: true,
outFields: ['*'],
mode: 1
},
editorLayerInfos: {
disableGeometryUpdate: false
},
legendLayerInfos: {
exclude: false,
layerInfo: {
title: 'Parcels'
}
},
layerControlLayerInfos: {
layerGroup: 'Parcels'
}
},
Any good references would help. Thank you
Here is the sample code for Labels:
https://developers.arcgis.com/javascript/latest/sample-code/labels-basic/index.html
Here are details step provided on the link:
>>To add labels to the layer, first we create a LabelClass and assign values for various properties, such as color and font.
const labelClass = { // autocasts as new LabelClass() symbol: { type: "text", // autocasts as new TextSymbol() color: "green", haloColor: "black", font: { // autocast as new Font() family: "playfair-display", size: 12, weight: "bold" } }, labelPlacement: "above-center", labelExpressionInfo: { expression: "$feature.MARKER_ACTIVITY" } });
>> This sample loads a PortalItem from ArcGIS Online, then adds the label class to the labelingInfo
property, and applies a renderer.
map.layers = [ new FeatureLayer({ portalItem: { // autocasts as new PortalItem id: "6012738cd1c74582a5f98ea30ae9876f" }, labelingInfo: [ labelClass ] }) ];
