1.在对应实体的HomePage新增按钮土地地图，调用landinfomap.JS（上传到系统WEB资源中）
2. New_landdata.JS中关键代码
//取经过筛选之后视图的FETCHXML，并保存在实体new_tempdata中(因XML过长,URL传值受到限制，目前只找到此方法),然后把保存的记录ID传参到LandDataMap.aspx页面(需另外做个批量删除的作业，来删除实体new_tempdata不需要的数据，可在数据管理—>> 批量删除记录里面创建)
function landinfomap(IDArr) {
var fetchxml = IDArr.GetParameter("effectiveFetchXml");
fetchxml = fetchxml.substring(fetchxml.indexOf(">") + 1, fetchxml.length) //去掉XML中的第一句
fetchxml = "<fetch mapping="logical" version="1.0">" + fetchxml;
var tempdata = new Object();
tempdata.new_fetchxml = fetchxml;
var jsontempdata = JSON.stringify(tempdata);
var createtempdata = CreateEntityRecordByISV("new_tempdata", false); //同步
createtempdata.send(jsontempdata);
if (createtempdata.status == 201) {
var newTempdata = JSON.parse(createtempdata.responseText).d;
var value = new Array();
value[0] = new Object();
value[0].id = newTempdata.new_tempdataId;
value[0].typename = "new_tempdata";
}
else {
alert("发生错误: " + JSON.parse(createphonecallReq.responseText).error.message.value);
}
var url = "../../ISV/LandDataMap.aspx?";
var someValue = window.showModalDialog(url + "landid=" + newTempdata.new_tempdataId,
"", "dialogWidth=800px;dialogHeight=600px;status=no;help=no;scrollbars=no");
}
//创建实体信息
function CreateEntityRecordByISV(entityschema, mode) {
if (typeof (mode) == "undefined") {
mode = false;
}
var serverUrl = Xrm.Page.context.getClientUrl();
var ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc" + "/" + entityschema + "Set";
var createEntityReq = new XMLHttpRequest();
createEntityReq.open("POST", ODataPath, mode);
createEntityReq.setRequestHeader("Accept", "application/json");
createEntityReq.setRequestHeader("Content-Type", "application/json; charset=utf-8");
return createEntityReq;
}
3 LandDataMap.JS
接收landinfomap.JS传过来的参数，并通过LandDataInfo.ashx去取数据
//取土地 function GetLandInfo() { //jquery取数据 $.ajax({ type: "post", contentType: "application/json", url: "_common/LandDataInfo.ashx?serverUrl=" + encodeURIComponent(serverUrl) + "&landid=" + encodeURIComponent(landid), data: "", dataType: '', success: function (retstr) { var cname; var cid; var clng; var clat; var makeInfo; var regArr = retstr.split(';'); markerArr = new Array(); map = new BMap.Map("divMap"); map.centerAndZoom(new BMap.Point(regArr[2], regArr[3]), 14); // 初始化地图,设置中心点坐标和地图级别 (经度，纬度) map.addControl(new BMap.NavigationControl()); // 添加平移缩放控件 map.addControl(new BMap.OverviewMapControl()); //添加缩略地图控件 map.enableScrollWheelZoom(); //启用滚轮放大缩小 map.addControl(new BMap.MapTypeControl({ mapTypes: [BMAP_NORMAL_MAP, BMAP_HYBRID_MAP] })); //添加地图类型控件 for (var i = 0; i < regArr.length; i++) { cname = regArr[i]; i++; cid = regArr[i]; i++; clng = regArr[i]; i++; clat = regArr[i]; if (clng != "" && clat != "") { //加载地图标注 makeInfo = new Object(); makeInfo.title = cname; makeInfo.content = cname; makeInfo.lng = clng; makeInfo.lat = clat; makeInfo.isOpen = 0; makeInfo.ID = cid; if (rtype == "C") makeInfo.icon = { DType: "C", w: 60, h: 40, l: 46, t: 21, x: 9, lb: 12 }; markerArr.push(makeInfo); } } map.clearOverlays(); addMarker(); } }); }
4. LandDataInfo.ashx
根据传过来的ID,先从new_tempdate取出保存的XML文件。因我这边需取经纬度，在原视图没有该列，所以我执行取出来的XML拿到GUID，然后重新再取了一次经纬度. CreateXml方法是采用分页 Cookie 对 FetchXML 查询的结果进行分页（因Fetchxml查询不能超过5千条，采用此方法解决）

string serverUrl = DNTRequest.GetQueryString("serverUrl");
string landid = DNTRequest.GetQueryString("landid");
serverUrl = serverUrl + "/XRMServices/2011/Organization.svc";

OrganizationServiceProxy orgSvc = crmOrg.GetOrganization(serverUrl);
string retstr = "";
retstr = GetLandInfo(orgSvc, landid);
retstr = retstr.Replace("{", "");
retstr = retstr.Replace("}", "");
retstr = retstr.Replace("null", "");
context.Response.Write(retstr);
}
