本篇主要讲述的是利用arcgis api实现图层在线编辑功能模块,效果图如下:
实现思路:
1.arcgis server发布的FeatureServer服务提供的图层在线编辑能力:
2.实现的在线编辑(增删改),主要是通过前端ajax请求后台FeatureServer服务来实现的
(1)http://120.199.78.138:6080/arcgis/rest/services/dlsde/FeatureServer/0/updateFeatures
public void ProcessRequest (HttpContext context) {
string featureserverurl = context.Request.Params["featureserverurl"];
string features = context.Request.Params["features"];
string param = "features=" + features + "&f=json";
string url = featureserverurl + "/updateFeatures";
string ret = PostDataToUrl(param, url, "application/x-www-form-urlencoded");
context.Response.Write(ret);
}
(2)http://120.199.78.138:6080/arcgis/rest/services/dlsde/FeatureServer/0/addFeatures
public void ProcessRequest (HttpContext context) {
string featureserverurl = context.Request.Params["featureserverurl"];
string features = context.Request.Params["features"];
string param = "features=" + features + "&f=json";
string url = featureserverurl + "/addFeatures";
string ret = PostDataToUrl(param, url, "application/x-www-form-urlencoded");
context.Response.Write(ret);
}
(3)http://120.199.78.138:6080/arcgis/rest/services/dlsde/FeatureServer/0/deleteFeatures
public void ProcessRequest (HttpContext context) {
string featureserverurl = context.Request.Params["featureserverurl"];
string id = context.Request.Params["OBJECTID"];
string param = "where=OBJECTID=" + id + "&f=json";
string url = featureserverurl + "/deleteFeatures";
string ret = PostDataToUrl(param, url, "application/x-www-form-urlencoded");
context.Response.Write(ret);
context.Response.End();
}
3.前端ajax请求
(1)添加一条记录:
var features = [];
var rec = {};
rec.attributes = {};
rec.geometry = DCI.editLayers.geometry;
rec.attributes["NAME"] = $("#update_name").val();
rec.attributes["KIND"] = $("#update_kind").val();
features.push(rec);
var feats = JSON.stringify(features);
/*[{ "attributes": { "NAME": "112", "KIND": "4080" }, "geometry": { "type": "point", "x": 121.29894825018249, "y": 39.72910692098025, "spatialReference": { "wkid": 4326 } } }]*/
var params = { features: feats, f: "pjson", featureserverurl: MapConfig.sdeURL };
$.ajax({
type: "post",
//dataType: "json",
url: getRootPath() + "handler/AddFeatureHandler.ashx",
data: params,
//async: false,//同步
success: function (response, textStatus) {
var ret = JSON.parse(response);
if (ret.addResults && ret.addResults[0].success) {
promptdialog("提示", "添加成功!");
DCI.editLayers.InitSde("");
DCI.editLayers.map.infoWindow.hide();
} else {
promptdialog("提示", "添加失败!");
}
},
error: function (e) {
var error = e;
promptdialog("提示", "响应超时!");
}
});
(2)修改一条记录:
var features = [];
var rec = {};
rec.attributes = {};
rec.attributes["OBJECTID"] = parseInt(objectid);
rec.attributes["NAME"] = $("#update_name").val();
rec.attributes["KIND"] = $("#update_kind").val();
features.push(rec);
var feats = JSON.stringify(features);
/*[{ "attributes": { "NAME": "112", "KIND": "4080" }, "geometry": { "type": "point", "x": 121.29894825018249, "y": 39.72910692098025, "spatialReference": { "wkid": 4326 } } }]*/
var params = { features: feats, f: "pjson", featureserverurl: MapConfig.sdeURL };
$.ajax({
type: "post",
//dataType: "json",
url: getRootPath() + "handler/UpdateFeatureHandler.ashx",
data: params,
//async: false,//同步
success: function (response, textStatus) {
var ret = JSON.parse(response);
if (ret.updateResults[0].success) {
promptdialog("提示", "更新成功!");
DCI.editLayers.InitSde("");
DCI.editLayers.map.infoWindow.hide();
} else {
promptdialog("提示", "更新失败!");
}
},
error: function (e) {
var error = e;
promptdialog("提示", "响应超时!");
}
});
(3)删除一条记录:
var objectid = parseInt(id);
var params = { OBJECTID: objectid, featureserverurl: MapConfig.sdeURL };
$.ajax({
type: "post",
//dataType: "json",
url: getRootPath() + "handler/DeleteFeatureHandler.ashx",
data: params,
//async: false,//同步
success: function (response, textStatus) {
var ret = JSON.parse(response);
if (ret.success) {
promptdialog("提示", "删除成功!");
DCI.editLayers.InitSde("");
DCI.editLayers.map.infoWindow.hide();
} else {
promptdialog("提示", "删除失败!");
}
},
error: function (e) {
var error = e;
promptdialog("提示", "响应超时!");
}
});
