Question

我有这个检查交易实体，"cse_vendor_name"（供应商主实体）和"cse_expense_tracker"上会有一个查找字段，所以每次我都会select一个cse_vendor_name 它将自动填充 cse_expense_tracker 的字段。我已经尝试过这个工作代码，但它没有，

function makeRequest(method, url) {
return new Promise(function (resolve, reject) {
    var xhr = new XMLHttpRequest();
    xhr.open(method, url);
    xhr.setRequestHeader("OData-MaxVersion", "4.0");
    xhr.setRequestHeader("OData-Version", "4.0");
    xhr.setRequestHeader("Accept", "application/json");
    xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    xhr.onload = function () {
        if (this.status >= 200 && this.status < 300) {

            resolve(xhr.response);
        } else {
            reject({
                status: this.status,
                statusText: xhr.statusText
            });
        }
    };
    xhr.onerror = function () {
        reject({
            status: this.status,
            statusText: xhr.statusText
        });
    };
    xhr.send();
});}

function setParentAccountbasedonPrimaryContact() {
var lookup1 = Xrm.Page.getAttribute("cse_vendor_name").getValue()[0].id;
var clientUrl = Xrm.Page.context.getClientUrl();
var query = clientUrl + "/api/data/v8.0/cse_vendormaster(" + lookup1.slice(1, -1) + ")?$select=_cse_expense_category_value";
makeRequest('GET', query)
.then(function (res) {
   var res2 = JSON.parse(res);
   var guid = res2._cse_expense_category_value;
   var query2 = clientUrl + "/api/data/v8.0/cse_checkingaccounttransaction(" + guid + ")?$select=cse_vendor_name";
   makeRequest('GET', query2)
 .then(function (response) {
   var res3 = JSON.parse(response);
   var value = new Array();
   value[0] = new Object();
   value[0].id = guid;
   value[0].name = res3.name;
   value[0].entityType = "cse_checkingaccounttransaction";
   Xrm.Page.getAttribute("cse_expense_category").setValue(value);


})
   .catch(function (err) {
       console.error('there was an error!', err.statusText);
   });


  })


  .catch(function (err) {
   console.error(' there was an error!', err.statusText);


  });
}

所以这就是每当我 select 编辑查找字段时填写查找字段的答案。这个解决方案的唯一问题是，该领域有一个问题说 "LookUp control error:cannot add item of typename= to the lookup control" 所以当我点击保存时。它将再次查找 select 数据。

function makeRequest(method, url) {
return new Promise(function (resolve, reject) {
    var xhr = new XMLHttpRequest();
    xhr.open(method, url);
    xhr.setRequestHeader("OData-MaxVersion", "4.0");
    xhr.setRequestHeader("OData-Version", "4.0");
    xhr.setRequestHeader("Accept", "application/json");
    xhr.setRequestHeader("Content-Type", "application/json; charset=utf-8");
    xhr.onload = function () {
        if (this.status >= 200 && this.status < 300) {

            resolve(xhr.response);
        } else {
            reject({
                status: this.status,
                statusText: xhr.statusText
            });
        }
    };
    xhr.onerror = function () {
        reject({
            status: this.status,
            statusText: xhr.statusText
        });
    };
    xhr.send();
});
}
function setExpenseCategorybasedonVendor() {
var lookup1 = Xrm.Page.getAttribute("cse_vendor_name").getValue()[0].id;
var clientUrl = Xrm.Page.context.getClientUrl();
var query = clientUrl + "/api/data/v8.0/cse_vendormasters(" + lookup1.slice(1, -1) + ")?$select=_cse_expense_category_value";
makeRequest('GET', query)
.then(function (res) {
var res2 = JSON.parse(res);
var guid = res2._cse_expense_category_value;
var query2 = clientUrl + "/api/data/v8.0/cse_expensemasters(" + guid + ")?$select=cse_name";
makeRequest('GET', query2)
.then(function (response) {
var res3 = JSON.parse(response);
var value = new Array();
value[0] = new Object();
value[0].id = guid;
value[0].name = res3.cse_name;
value[0].entityType = "cse_expensemasters"; 
Xrm.Page.getAttribute("cse_expense_category").setValue(value);
})
.catch(function (err) {
console.error('there was an error!', err.statusText);
});
})
.catch(function (err) {
console.error(' there was an error!', err.statusText);
});
}
