arcgis api for javascript从地图如何读取要素
arcgis api for javascript如何读取要素，通过ajax请求得到的。
比如：
https://gis118.arcgisonline.cn/arcgis/sharing/rest/content/items/f08f5c59cd89420abf7e585eaa260ddd/data
可以得到FeatureLayer要素服务，这里只需要配置好f08f5c59cd89420abf7e585eaa260ddd，即itemid，就可以得到operationalLayers，得到的是一个数组，然后根据类型匹配。
{"operationalLayers":[{"id":"15d1ac59ea4-layer-0","opacity":1,"title":"Aggregation of bigDataFileShares xin3 csv by hexagon bins - Aggregation of bigDataFileShares xin3 csv by hexagon bins","url":"https://gis118.arcgisonline.cn/arcgis/rest/services/Hosted/Aggregation_of_bigDataFileShares_xin3_csv_by_hexagon_bins/FeatureServer/0","visibility":true,"layerType":"ArcGISFeatureLayer","itemId":"62be1d8c97c4461383ea4ec738e96c5c","popupInfo":{"fieldInfos":[{"fieldName":"COUNT","label":"COUNT","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"COUNT_MmeUeS1apId","label":"COUNT_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SUM_MmeUeS1apId","label":"SUM_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MIN_MmeUeS1apId","label":"MIN_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MAX_MmeUeS1apId","label":"MAX_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MEAN_MmeUeS1apId","label":"MEAN_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"RANGE_MmeUeS1apId","label":"RANGE_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SD_MmeUeS1apId","label":"SD_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"VAR_MmeUeS1apId","label":"VAR_MmeUeS1apId","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"COUNT_Lat","label":"COUNT_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SUM_Lat","label":"SUM_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MIN_Lat","label":"MIN_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MAX_Lat","label":"MAX_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MEAN_Lat","label":"MEAN_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"RANGE_Lat","label":"RANGE_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SD_Lat","label":"SD_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"VAR_Lat","label":"VAR_Lat","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"COUNT_Lon","label":"COUNT_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SUM_Lon","label":"SUM_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MIN_Lon","label":"MIN_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MAX_Lon","label":"MAX_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"MEAN_Lon","label":"MEAN_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"RANGE_Lon","label":"RANGE_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"SD_Lon","label":"SD_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"VAR_Lon","label":"VAR_Lon","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"COUNT_Time","label":"COUNT_Time","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"ANY_Time","label":"ANY_Time","visible":true},{"fieldName":"COUNT_UUID","label":"COUNT_UUID","visible":true,"format":{"digitSeparator":true,"places":2}},{"fieldName":"ANY_UUID","label":"ANY_UUID","visible":true},{"fieldName":"globalid","label":"globalid","visible":true},{"fieldName":"OBJECTID","label":"OBJECTID","visible":true,"format":{"digitSeparator":true,"places":2}}],"showAttachments":false,"title":"Aggregation of bigDataFileShares xin3 csv by hexagon bins -

核心代码：
var itemURL = portalitem + webscene + "/data";esriRequest(itemURL, {responseType: "json"
}).then(function (response) {// The requested data
var Layers = response.data.operationalLayers;//this.config.operationalLayers = response.data.operationalLayers;
_self._getLayersData(Layers);});
},
