Ms CRM 中的 Javascript(带有 odata 查询)无法正常工作？

我创建了一个javaScript(顺便说一下我昨天才学的)

此脚本设置为在 Accounts 实体的 OnSave 事件时触发。我使用我在 Internet 上找到的查询生成器工具构建了一个 odata 查询，该工具应该检索所有任务($select=ActivityId,CreatedOn)并且在 2015-01-26T18:30:00.000Z($filter=CreatedOn)之前创建ge datetime'2015-01-26T18:30:00.000Z')

这是来自查询构建器的实际查询:

$.ajax({
    type: "GET",
    contentType: "application/json; charset=utf-8",
    datatype: "json",
    url: Xrm.Page.context.getClientUrl() + "/XRMServices/2011/OrganizationData.svc/TaskSet?$select=ActivityId,CreatedOn&$filter=CreatedOn ge datetime'2015-01-26T18:30:00.000Z'",
    beforeSend: function (XMLHttpRequest) {
        XMLHttpRequest.setRequestHeader("Accept", "application/json");
    },
    async: true,
    success: function (data, textStatus, xhr) {
        var results = data.d.results;
   for (var i = 0; i < results.length; i++) {
        var ActivityId = results[i].ActivityId;
        var CreatedOn = results[i].CreatedOn;
   }
    },
    error: function (xhr, textStatus, errorThrown) {
        alert(textStatus + " " + errorThrown);
    }
});

在查询构建器中它返回结果:

[
    {
        "CreatedOn": "/Date(1422342587000)/",
        "ActivityId": "c23ba479-f3a5-e411-80dc-c4346bada6a4"
    },
    {
        "CreatedOn": "/Date(1422342783000)/",
        "ActivityId": "ba7754ee-f3a5-e411-80dc-c4346bada6a4"
    },
    {
        "CreatedOn": "/Date(1422343425000)/",
        "ActivityId": "12d40a6d-f5a5-e411-80dc-c4346bada6a4"
    }
]

在结果中，我发现创建日期返回值 "CreatedOn": "/Date(1422343425000)/", ..

我想检索在 Accounts 实体中创建新记录之前 7 天创建的所有任务..所以我编写逻辑根据通用值 var current_date = Date().valueOf() 获取当前数据 并以毫秒为单位减去 7 天 (7*24*60*60*1000=604800000)var week_earlier = current_date - 604800000;

在下面的代码中你可以看到我做了什么

function retrive()
{
    //var date =2015-01-26T18:30:00.000Z;
    var current_date = Date().valueOf();
    var week_earlier = current_date - 604800000;



    $.ajax({
        type: "GET",
        contentType: "application/json; charset=utf-8",
        datatype: "json",
        url: Xrm.Page.context.getClientUrl() + "/XRMServices/2011/OrganizationData.svc/TaskSet?$select=ActivityId,CreatedOn&$filter=CreatedOn ge datetime'"+week_earlier+"'",
        beforeSend: function (XMLHttpRequest) {
            XMLHttpRequest.setRequestHeader("Accept", "application/json");
        },
        async: true,
        success: function (data, textStatus, xhr) {
            var results = data.d.results;
            for (var i = 0; i < results.length; i++) {
                var ActivityId = results[i].ActivityId;
                var CreatedOn = results[i].CreatedOn;
            }

            alert("number of records found  :"+results.length);

        },
        error: function (xhr, textStatus, errorThrown) {
            alert(textStatus + " " + errorThrown);
        }
    });

但它不起作用....它显示

"error Bad Request"

我也尝试在浏览器的 url 中查询

https://avikcompany.crm5.dynamics.com/XRMServices/2011/OrganizationData.svc/TaskSet?$select=CreatedOn,ActivityId&$filter=CreatedOn ge datetime'1422342587000'(this '1422342587000' is present in result  of the previously fired query).

但它也抛出了一个错误

任何人都可以告诉我哪里出错了吗？(我假设 crm odata 服务不接受我提到的日期值)或者如何将日期转换为这种格式“yyyy-mm-ddThh:mm:ss.uuuZ”

最佳答案

您可以使用 toISOString() 轻松获取该格式的日期；

http://jsfiddle.net/j5m97nfv/3/ 

var current_date = new Date().valueOf();
var week_earlier = new Date(current_date - 604800000);
var n = week_earlier.toISOString();

您在上面的代码中遇到的一个问题是您没有构造新的 Date 对象。您的 current_date 实际上返回一个日期字符串，该字符串不是以毫秒为单位的日期表示形式。你需要新的日期()；
