我想知道我想要做的事情是否可行。我正在尝试在我的网站上添加一个使用ArcGIS Javascript API编写的功能表。我已设法从Geoserver链接我的图层并在地图上查看此图但我正努力在我的网站中的表格中显示我的记录。
到目前为止，这是我的代码：
require([
"esri/layers/FeatureLayer",
"esri/dijit/FeatureTable",
"esri/layers/WMSLayer",
"esri/layers/WMSLayerInfo",
"esri/geometry/Extent",
"esri/graphicsUtils",

"esri/symbols/PictureMarkerSymbol",
"esri/map",
"dojo/dom",
"dojo/parser",
"dojo/ready",
"dojo/on",
"dijit/layout/ContentPane",
"dijit/layout/BorderContainer"
], function (
FeatureLayer, FeatureTable, WMSLayer, WMSLayerInfo, Extent, graphicsUtils, Query, PictureMarkerSymbol, Map,
dom, parser, ready, on, ContentPane, BorderContainer
) {
parser.parse();
ready(function(){
var map = new Map("map",{
basemap: "streets",
extent: new Extent({xmax: -1.1487, xmin: 51.065,
ymax: -1.1274, ymin: 51.097,
"spatialReference":{"wkid":27700,"latestWkid":4326}
})
});
//Load a FeatureTable to the application once map loads
map.on("load", loadTable);
function loadTable(){
// editable FeatureLayer
var wmsLayer = new WMSLayer("", {
mode: WMSLayer.MODE_ONDEMAND,
outFields: ["*"],
visible: true,
id: "fLayer2"
});
var wmsLayer = new WMSLayer("http://localhost:8080/geoserver/RSAC/ows?service=wfs&version=1.0.0&request=GetCapabilities", {

});
wmsLayer.on("error", function (response){
console.log("Error: %s", response.error.message);
});
map.addLayer(wmsLayer);
// set a selection symbol for the featurelayer
var selectionSymbol = new PictureMarkerSymbol("https://sampleserver6.arcgisonline.com/arcgis/rest/services/RedlandsEmergencyVehicles/FeatureServer/1/images/3540cfc7a09a7bd66f9b7b2114d24eee", 48 ,48);
wmsLayer.setSelectionSymbol(selectionSymbol);
// listen to featurelayer click event to handle selection
// from layer to the table.
// when user clicks on a feature on the map, the corresponding
// record will be selected in the table.
wmsLayer.on("click", function(evt) {
var idProperty = wmsLayer.id,
feature,
featureId,
query;
if (evt.graphic && evt.graphic.attributes && evt.graphic.attributes[idProperty]) {
feature = evt.graphic,
featureId = feature.attributes[idProperty];
query = new Query();
query.returnGeometry = false;
query.id = [featureId];
query.where = "1=1";
wmsLayer.selectFeatures(query, wmsLayer.SELECTION_NEW);
}
});
// Redlands police vehicle locations layer
// this layer is an editable layer
map.addLayer(wmsLayer);
//create new FeatureTable and set its properties
var wmsLayer = new FeatureTable({
featureLayer : wmsLayer,
map : map,
editable: true,
syncSelection: true,
dateOptions: {
datePattern: 'M/d/y',
timeEnabled: true,

// use fieldInfos object to change field's label (column header),

// you will not be able to edit callnumber field in this example.
fieldInfos: [
{
name: 'id',
alias: 'Polygon Id',
editable: false //disable editing on this field
},
{
name: 'photos',
alias: 'photos',
},
],
// add custom menu functions to the 'Options' drop-down Menu
menuFunctions: [
{
label: "Field_boundary_WGS84",
callback: function(evt){
console.log(" -- evt: ", evt);
// set definition expression on the layer
// show only available emergency vehicles
wmsLayer.setDefinitionExpression("status = 0");
// call FeatureTable.refresh() method to re-fetch features
// from the layer. Table will only show records that meet
// layer's definition expression creteria.
wmsLayer.refresh();
}
},{
label: "Show All Field Boundaries",
callback: function(evt){
console.log(" -- evt: ", evt);
wmsLayer.setDefinitionExpression("1=1");
myFeatureTable.refresh();
}
}]
}, 'myTableNode');
myFeatureTable.startup();
// listen to refresh event
myFeatureTable.on("refresh", function(evt){
console.log("refresh event - ", evt);
});
}
});
});
答案 0 :(得分：0)
FeatureTable类是一个仅使用要素图层的窗口小部件。因此，在将wmslayer对象设置为其要素图层参数的情况下创建其实例是错误的。
如果必须使用featureTable小部件，则可以执行以下操作。
获取ArcGIS shapefile或其他受支持的类型。
使用shapefile通过arcgis服务器发布要素服务，因此您可以拥有要素service.say：https://services.arcgis.com/V6ZHFr6zdgNZuVG0/arcgis/rest/services/california_census_blocks/FeatureServer/0
使用ags api代码为js
以下是一个例子：
