Javascript var 查询返回 [object 对象]

Question

我有一个 JavaScript 文件正在查询 SharePoint 列表。我正在查询两个下拉列表。第一个 - LifeCycleStatus - 返回正常，但优先级下拉返回 screen grab [object OBJECT]。我认为这与 var 查询字符串有关。我已将 'Priority' 列添加到 var 查询中，但它似乎没有任何区别

var query = "http://collaboration- 
   de.vxxx.com/sites/it/SystemInventory/_vti_bin/listdata.svc/Devices?$expand=LifeCycleStatus&Priority&$filter=Id eq " + window.DeviceId + "";

完整 JavaScript 下面：

function getDeviceDetails() {
var txtTitle = "";
var txtOverview = "";
var txtAccessories = "";
var txtDevicetype = "";
var txtTypicalDeviceUsage ="";
var txtKnownSystemIssues ="";
var txtLifeCycles = "";
var txtTrafficlight = "";
    var tempLCS2 = "";

var query = "http://collaboration-dev.xxx/sites/it/SystemInventory/_vti_bin/listdata.svc/Devices?$expand=LifeCycleStatus&Priority&$filter=Id eq " + window.DeviceId + "";
    var call = $.ajax({
        url: query,
        type: "GET",
        dataType: "json",
        headers: {
            Accept: "application/json;odata=verbose"
        }       
    });
call.done(function (data,textStatus, jqXHR){
$.each(data.d.results, function(index, item) {
        var tempID = item.Id;
        var tempTitle = item.Title;




         var LifeCycleStart = item.DeviceAvailableFrom;



        var LifeCycleStatus = item.LifeCycleStatusValue;
        var DeviceOverView = item.Description;
        var AccessDetails = item.Accessories;
        var DeviceKind = item.Devicetype;
        var Usage = item.TypicalUsage;
        var DevicePriority = item.Priority;


        txtTitle = "<p>" + LifeCycleStart + "</p><p>" + LifeCycleStatus + "</p>";
        txtOverview = "<p>" + DeviceOverView + "</p>";
        txtAccessories = "<p>" + AccessDetails + "</p>";  
        txtDevicetype = "<p>" + DeviceKind  + "</p>";
        txtTypicalDeviceUsage = "<p>" + Usage + "</p>";
        txtTrafficlight = "<p>" + DevicePriority + "</p>";
       // txtKnownSystemIssues = "<p>" + KnownSystem + "</p>"
    });
    $('#devicedetails').append($(txtTitle));  
    $('#deviceoverview').append($(txtOverview));
    $('#devicekind').append(txtDevicetype);
    $('#deviceacc').append(txtAccessories);
    $('#deviceuse').append(txtTypicalDeviceUsage);
    $('#devicestatus').append(txtTrafficlight);

});





call.fail(function (jqXHR,textStatus,errorThrown){
    alert("Error retrieving data: " + jqXHR.responseText);
});

}

Answer 1

"Priority" 和 "LifeCycleStatus" 包含一个对象。您可以使用 debugger/console 来查看对象是什么 - 我打赌它包含一个带有值的字符串，以及值的内部 ID，可能还有其他内容。将对象转换为字符串 returns "[object Object]".

"PriorityValue" 和 "LifeCycleStatusValue" 可能是值字符串的简写。

Javascript var 查询返回 [object 对象]
