im通过web api调用中的一些嵌套json进行循环，并将数据绑定到表。foreach在第一个循环后失败。
这是来自web api调用的json
[{"$id":"1","JobID":1,"JobsListID":1,"BookingID":2,"TimeAllowed":20,"TimeTaken":22,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-04T09:00:00","Difficulty":1,"CompleteDate":"2014-11-04T09:22:00","booking":null,"jobs_mechanics":[],"jobslist":{"$id":"2","JobsListID":1,"JobCategoryID":1,"Description":"Change Tyres ","Name":"Tyres","jobs":[{"$ref":"1"},{"$id":"3","JobID":4,"JobsListID":1,"BookingID":2,"TimeAllowed":18,"TimeTaken":22,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-06T10:30:00","Difficulty":5,"CompleteDate":"2014-11-06T10:52:00","booking":null,"jobs_mechanics":[],"jobslist":{"$ref":"2"},"timessheets":[]}],"jobscategory":null,"model_jobslist":[]},"timessheets":[]},{"$ref":"3"},{"$id":"4","JobID":9,"JobsListID":2,"BookingID":2,"TimeAllowed":null,"TimeTaken":null,"Comments":null,"Status":"new","Notes":null,"TimeStarted":null,"Difficulty":5,"CompleteDate":null,"booking":null,"jobs_mechanics":[],"jobslist":{"$id":"5","JobsListID":2,"JobCategoryID":2,"Description":"Fix or Replace Radiator","Name":"Fix Radiator","jobs":[{"$ref":"4"}],"jobscategory":null,"model_jobslist":[]},"timessheets":[]},{"$id":"6","JobID":2,"JobsListID":3,"BookingID":2,"TimeAllowed":30,"TimeTaken":27,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-05T15:00:00","Difficulty":1,"CompleteDate":"2014-11-05T15:27:00","booking":null,"jobs_mechanics":[],"jobslist":{"$id":"7","JobsListID":3,"JobCategoryID":3,"Description":"Replace Door","Name":"Door","jobs":[{"$ref":"6"},{"$id":"8","JobID":3,"JobsListID":3,"BookingID":2,"TimeAllowed":40,"TimeTaken":40,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-05T14:05:00","Difficulty":3,"CompleteDate":"2014-11-05T14:45:00","booking":null,"jobs_mechanics":[],"jobslist":{"$ref":"7"},"timessheets":[]},{"$id":"9","JobID":7,"JobsListID":3,"BookingID":2,"TimeAllowed":null,"TimeTaken":null,"Comments":"Some comments","Status":"new","Notes":null,"TimeStarted":null,"Difficulty":2,"CompleteDate":null,"booking":null,"jobs_mechanics":[],"jobslist":{"$ref":"7"},"timessheets":[]}],"jobscategory":null,"model_jobslist":[]},"timessheets":[]},{"$ref":"8"},{"$ref":"9"},{"$id":"10","JobID":5,"JobsListID":4,"BookingID":2,"TimeAllowed":70,"TimeTaken":68,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-06T10:30:00","Difficulty":2,"CompleteDate":"2014-11-07T12:23:00","booking":null,"jobs_mechanics":[],"jobslist":{"$id":"11","JobsListID":4,"JobCategoryID":4,"Description":"Weld and patch old exhaust","Name":"Weld Exhaust","jobs":[{"$ref":"10"}],"jobscategory":null,"model_jobslist":[]},"timessheets":[]},{"$id":"12","JobID":6,"JobsListID":5,"BookingID":2,"TimeAllowed":50,"TimeTaken":50,"Comments":"Some comments","Status":"complete","Notes":null,"TimeStarted":"2014-11-08T15:40:00","Difficulty":3,"CompleteDate":"2014-11-08T16:30:00","booking":null,"jobs_mechanics":[],"jobslist":{"$id":"13","JobsListID":5,"JobCategoryID":5,"Description":"Replace current brakes pads","Name":"New Brake Pads","jobs":[{"$ref":"12"},{"$id":"14","JobID":8,"JobsListID":5,"BookingID":2,"TimeAllowed":null,"TimeTaken":null,"Comments":"Some comments","Status":"new","Notes":null,"TimeStarted":null,"Difficulty":1,"CompleteDate":null,"booking":null,"jobs_mechanics":[],"jobslist":{"$ref":"13"},"timessheets":[]},{"$id":"15","JobID":10,"JobsListID":5,"BookingID":2,"TimeAllowed":50,"TimeTaken":48,"Comments":null,"Status":"complete","Notes":null,"TimeStarted":"2014-11-08T09:30:00","Difficulty":4,"CompleteDate":"2014-11-08T10:18:00","booking":null,"jobs_mechanics":[],"jobslist":{"$ref":"13"},"timessheets":[]}],"jobscategory":null,"model_jobslist":[]},"timessheets":[]},{"$ref":"14"},{"$ref":"15"}]
这是输出
作业ID作业列表ID1 1
<table>
<thead>
<tr>
<th>Job ID</th>
<th>JobList ID</th>
</tr>
</thead>
<tbody data-bind="foreach: Jobs">
<tr>
<td data-bind="text: JobID"></td>
<td data-bind="text: jobslist.JobsListID"></td>
</tr>
</tbody>
它适用于第一个作业并绑定数据，然后停止？？？
我在调试器中得到这个消息消息：JobID没有定义
脚本代码
var ViewModel = function () {
var self = this;
self.Jobs = ko.observableArray();
self.search = ko.observableArray();
self.GJobs = function (search) {
GetJobs(self.search);
}
self.GetMenu = function (JobID) {
GetMenu(JobID);
}
function GetJobs(search) {
$.ajax({
type: "GET",
url: 'api/mechanicphone',
data: { reg: search },
dataType: 'json',
contentType: 'application/json',
success: function (data) {
self.Jobs(data);
},
error: function (data) {
$('#MechMobile').html('<h3>Error in retrieval</h3>');
}
});
}
只需从web api调用中查看您的JSON，您就有一个问题——在第二个作业的位置，您有以下JSON：
{
"$ref":"3"
}
尝试使用此JSON:

我无法用您提供的代码复制您的问题。你能提供一个例子吗？
您是如何将JSON与viewModel进行映射的？看看映射插件如果你试图将json添加到一个可观察的数组中，唯一的绑定将是添加/删除作业表单KO对象属性Jobs，这就是你想要的吗？
