我正在将我的代码修改为 Angular 以用于我使用 javascript/jquery 逻辑完成的时间表项目。我正在尝试利用角度函数来使一切顺利进行，但我对如何在 ng-repeat 表上使其工作感到非常困惑。

我拥有的是 2 个单独的数据集，其中我保存了时间表数据（子数据），然后是主数据（父数据）。子数据包含父数据的 ID，我以这种方式链接它们，然后找出将数据合并到适当行的逻辑。

这是使用 javasript/jquery 的工作表： https ://jsfiddle.net/tj6bcjos/11/

<table class="table" id="my_table">
  <thead>
    <tr>
      <td>ID</td>
      <td>Description</td>
      <td>Start</td>      
      <td>End</td>      
      <td>Hours</td>
      <td>Day or Night?</td>      
    </tr>
  </thead>
  <tbody></tbody>
</table>

$.mockjax({
    url: "Ajax/Path1",
    contentType: "application/json;odata=verbose",
    responseText: {
        d: {
            results: [{
                ID: "17",
                description: "Description 1"
            }, {
                ID: "22",
                description: "Description 2"
            }, {
                ID: "34",
                description: "Description 3"
            }, {
                ID: "54",
                description: "Description 4"
            }]
        }
    }
});

  data_array = {};
    data1=null

         if(data1!=null && data2 !=null)
     {
        processData();  
     }

    }//sucess end
  });

  $.ajax({
    url:"Ajax/Path2",           
    dataType: "json",
    cache: false,
    success: function (data) {
            data2 = data;
         if(data1!=null && data2 !=null)
     {
        processData();  
     }

    }
  });
  //can only process if both data1 and 2 are available
  function processData()
  {
      $(data1.d.results).each(function(i,p){ //loop thru parents
            pId = p.ID;
          //bring back the match children
                    children = data2.d.results.filter(function(d){

            return d.ID_of_parent == pId
          })
        s=[]
        e=[]
        h=[] 
        n=[] //start, end  hours...  
       $(children).each(function(i,c)
      {
                    s.push(c.Start);
          e.push(c.End);
          h.push(c.Hours);
          n.push(c.Day_or_night);

      })
         rw = '<tr><td>'+p.ID+'</td><td>'+p.description+'</td><td>'+
          s.join('<br>')+'</td><td>'+e.join('<br>')+'</td><td>'+h.join('<br>')
          +'</td><td>'+n.join('<br>')+'</td></tr>'
      console.log(rw)

        $('#my_table tbody').append(rw);


        })
  }

对于我的一生，我无法弄清楚逻辑应该如何在 ng-repeat 这个复杂的情况下进行。有人知道完成相同任务的简单方法吗？

我已经更新了你的 plunker 以使用 Angular。我希望你会同意这在 Angular 与 jquery/js 中更容易且更具可读性。

https://jsfiddle.net/tj6bcjos/13/

标记：

<table class="table" id="my_table">
  <thead>
    <tr>
      <td>ID</td>
      <td>Description</td>
      <td>Start</td>      
      <td>End</td>      
      <td>Hours</td>
      <td>Day or Night?</td>      
    </tr>
  </thead>
  <tbody>
    <tr ng-repeat="entry in mergedSet">
      <td>{{entry.id}}</td>
      <td>{{entry.description}}</td>
      <td>
        <ul>
          <li ng-repeat="start in entry.start track by $index">{{start}}</li>
        </ul>
      </td>
       <td>
        <ul>
          <li ng-repeat="end in entry.end track by $index">{{end}}</li>
        </ul>
      </td>
      <td>
        <ul>
          <li ng-repeat="hour in entry.hours track by $index">{{hour}}</li>

可以这样写。

首先编写一个模板，ng-repeat在变量 say 上使用和呈现表格timesheet

现在声明timesheet为您的controller. 喜欢$scope.timesheet = []

接下来在processData函数中而不是形成rwand appending，将其推送到临时变量并最终将其分配给$scope.timesheet. 如果 UI 正确绑定到timesheet变量，则数据将自动显示。
