javascript - 如何消除以下错误。尝试创建一个函数来在 mscrm 中创建实体的记录

Question

在下面的代码中，我创建了两个函数，其中一个函数我使用 msd-crm 动态 365 api 代码来创建记录，在主函数中我传递参数，但当我使用数组时作为参数，它显示此错误。我能够传递的单一值。

//Generic.js

if (typeof (API) == "undefined")
{ API = {}; }
API.CommonFunctions = {

    CreateRequest: function (entityname, fieldNames, fieldValues, process, MSCRMcallerId, requestType) {
        debugger;
        var entity = {};
        
        
        for (var a = 0; a < fieldNames.length; a++) {

            entity.fieldNames[a] = fieldValues[a];
        }
        
        //entity.lastname = fieldValues;


        var req = new XMLHttpRequest();
        req.open(requestType, Xrm.Page.context.getClientUrl() + "/api/data/v8.2/" + entityname, process);
        req.setRequestHeader("OData-MaxVersion", "4.0");
        req.setRequestHeader("OData-Version", "4.0");
        req.setRequestHeader("Accept", "application/json");
        req.setRequestHeader("Content-Type", "application/json; charset=utf-8");

        req.setRequestHeader("MSCRMCallerID", MSCRMcallerId);
        req.onreadystatechange = function () {
            if (this.readyState === 4) {
                req.onreadystatechange = null;
                if (this.status === 204) {
                    var uri = this.getResponseHeader("OData-EntityId");
                    var regExp = /\(([^)]+)\)/;
                    var matches = regExp.exec(uri);
                    var newEntityId = matches[1];
                } else {
                   Xrm.Utility.alertDialog(this.statusText); //
                }
            }
        };
        req.send(JSON.stringify(entity));
    }
}






//main.js

if (typeof (API) == "undefined")
{ API = {}; }
API.MainFuntions = {

    CreateAccount: function(){

        var fieldNames = ["lastname", "gendercode", "wholenumber"];

        var fieldValues = ["Hello", 1,12];

        API.CommonFunctions.CreateRequest("contacts", fieldNames,fieldValues, "true", "1232", "POST")

    }
}

您的问题在于您的 JavaScript 以及您如何构建对象。首先，我认为您想要做的是:

    for (var a = 0; a < fieldNames.length; a++) {
        entity[fieldNames[a]] = fieldValues[a];
    }

而且，你也让自己陷入困境。为什么不按照正常方式在外部构建对象并将其发送进去，而不是构建这些数组？

要扩展...这样的东西可能会起作用并且看起来更好:

CreateRequest: function (entityname, entity, process, MSCRMcallerId, requestType) {
    debugger;
    // don't need all of this now as your passing in an entity...
    //var entity = {};
    //for (var a = 0; a < fieldNames.length; a++) {
    //    entity.fieldNames[a] = fieldValues[a];
    //}

并这样调用它:

    var contact = {
        lastname:"Hello",
        gendercode:1
      };

    // or even set properties on it like this:
    contact.wholenumber= 12;

   // And just send in the entity
    API.CommonFunctions.CreateRequest("contacts", contact, "true", "1232", "POST")
