Javascript 已检查角度引导模式切换是否存在数据

首先，我为一个冗长的问题道歉，因为我不能发布plunker，因为它有从后端带来数据的服务。因此，我发布了尽可能多的数据作为样本

我有一个使用bootstrap的angular js应用程序。我定义了一个模态，其具有下表：

<div class="panel panel-default" style="float:left;width:525px;">
    <div class="panel-body" data-spy="scroll" data-target="#navbar-example" data-offset="0" style="height:200px;overflow:auto;position:relative;">
        <table class="table table-hover checkbox">
            <tr>    
                <th>Course</th> 
                <th>Title</th>      
                <th>Credits</th>  
            </tr>

            <tr ng-repeat="child in requirements">
                {% verbatim %}
                <td class="vcenter">
                <input type="checkbox" ng-checked="" ng-click="toggleCheck(child)" ng-disabled="required == (planned + completed) && (selectedCourses.indexOf(child) == -1)" value=""/>
                                            {{child.course.subject}}-{{child.course.course_no}}
                </td>
                <td class="vcenter">{{child.course.course_name}}</td>
                    {% endverbatim %}
                <td class="vcenter">3</td> 
            </tr>
        </table>
    </div>

我的要求是：

[
    {
        "category": 163, 
        "course": {
            "course_id": 1023,

            "academic_level": "CR", 
            "grade_scheme": "CR", 
            "credit_type": "I",

            "transfer_status": "060"
        }
    }, 
    {
        "category": 163, 
        "course": {
            "course_id": 81, 
            "subject": "ENGL",

            "ceus": "", 
            "transfer_status": "010"
        }
    }
]

下一步是检查表中所有已经参加的课程。这些详细信息将从mpttdetails和planneddetails中检索

那么，我如何在表中打开模式，该表已经检查了mpttdetails和计划细节中存在的课程

---

注：

$scope.requirements.course.{{subject}}-{course\u no}

中的课程需要与

mpttdetails.student\u academic\u credit.course\u name

和

planneddetails.course\u name

进行比较。但我不知道如何做到这一点。请帮忙

你能把这个问题简化成一般性的问题吗？或者至少用硬编码的json制作一个plunkr来模拟服务的响应？@crozzfire:不清楚什么是确定是否应该缓存的标准，以及实现它的问题是什么（例如，为什么你没有一个函数来接收

child.course

，并确定是否应该检查它？）。Hi@j.wittwer..我尝试了一个函数，并在这里更好地构建了这个问题：@ExpertSystem:我用你在这里提到的函数重新定义了这个问题。
