CRM中复制记录的方法

function Copy() {

 //step 1 查询当前信息

var new_code = Xrm.Page.getAttribute("new_code").getValue();//促销编号
var new_name = Xrm.Page.getAttribute("new_name").getValue();//促销名称

  var new_ruletypecode = Xrm.Page.getAttribute("new_ruletypecode").getValue();//规则类型    选项集 

//step 2 组合成新的对象

var newRule = new Object();
newRule.new_code = new_code;
newRule.new_name = new_name;
newRule.new_ruletypecode = { Value: new_ruletypecode };  // 选项集 必须使用这种赋值方法，否则就会报错



//step 3 创建新记录
var jsonEntity = window.JSON.stringify(newRule);
var createEntityReq = CreateEntityRecord("new_Entity", false, false);
createEntityReq.send(jsonEntity);
if (createEntityReq.readyState == 4 /* complete */) {
if (createEntityReq.status == 201) {

//做想做的事情

}

}

}

//创建XMLHttpRequest,创建实体信息
function CreateEntityRecord(entityschema, syncmode, isvmode) {
if (typeof (syncmode) == "undefined") {
syncmode = false;
}
if (typeof (isvmode) == "undefined") {
isvmode = false;
}

var orguniquename = "";
if (isvmode) {
orguniquename = GetGlobalContext().getOrgUniqueName(); //GetGlobalContext function exists in ClientGlobalContext.js.aspx
} else {
orguniquename = Xrm.Page.context.getOrgUniqueName();
}

var serverUrl = "";
if (location.href.toLowerCase().indexOf(orguniquename.toLowerCase() + ".") > 0) {
serverUrl = "//" + location.host;
}
else {
serverUrl = "//" + location.host + "/" + orguniquename;
}
serverUrl = document.location.protocol + serverUrl;
var ODataPath = serverUrl + "/XRMServices/2011/OrganizationData.svc" + "/" + entityschema + "Set";

var createEntityReq = new XMLHttpRequest();
createEntityReq.open("POST", ODataPath, syncmode);
createEntityReq.setRequestHeader("Accept", "application/json");
createEntityReq.setRequestHeader("Content-Type", "application/json; charset=utf-8");
return createEntityReq;
}
