Multiple print using Export Web Map Task

RichardMoussopo

I'd like to query some parcels and loop through each one of them to export it out using Print Task. what would be the best approach ? (API 4.6)

I thought I share some code:

//******************************************* */

let view = new MapView({

map: webmap,

container:"mapview"

});

view.then(e=>{

let parcels = e.map.allLayers.find(layer => {return layer.title ==="Parcels"});

const query = new Query();

query.outFields = ["*"];

query.returnGeometry = true;

query.where ="owner='testing'";

parcels.queryFeatures(query).then(res =>{

console.log(res);

var parcelArray = res.features;

parcelArray.forEach(parcel =>{

GetPrintImgUrl(parcel).then(res=>{

// display printed map list here on the page

})

})

})

//Print method that returns the exported map url

var GetPrintImgUrl = function(feature){

let _promise = new Promise((resolve, reject) =>{

view.graphics.removeAll();

var fillSymbol = {

type: "simple-fill",

style: "none",

outline: {

width: 2,

color: [255, 255, 0, 1]

}

};

let _current_parcel = new Graphic(feature.geometry, fillSymbol);

view.graphics.add(_current_parcel);

//[1] zoom to the current parcel extent

view.extent = feature.geometry.extent;

view.zoom = 20;

//[2] export this map

var printTask = new PrintTask({

url: "https://.../ExportWebMap/GPServer/Export%20Web%20Map"

});

var template = new PrintTemplate({

format: "jpg",

exportOptions: {

width:500,

height:600

},

layout: "map-only",

layoutOptions: {

titleText: "Parcel 0025655452"

}

});

var params = new PrintParameters({

view: view,

template: template

});

printTask.execute(params).then(printResult=>{ // This printTask does not work result in Error: ["Error executing tool. Export Web Map Job ID: j40a9373610e84ac59f26ecc1eb1af0fe"]

resolve(printResult);

});

});

return _promise;

};

})
