一，ng-repeat/filter/orderby使用

数据结构：

{
    "result":true,"ItemWeekIndex":"第二周","Content":[
        {
            "weekIndex":1,"courseInfo":"11教501高等数学","periodTimesIndex":1
        },{
            "weekIndex":1,"courseInfo":"11教232大学英语(一)","periodTimesIndex":2
        },"courseInfo":"11教232食品安全学","periodTimesIndex":4
        },{
            "weekIndex":2,"courseInfo":"11教232乳制品工艺学","courseInfo":"11教232大学英语(二)","courseInfo":"11教232计算机基础(一)",{
            "weekIndex":3,"courseInfo":"11教234人体解剖学","courseInfo":"11教234植物资源学","periodTimesIndex":3
        },"courseInfo":"11教234花卉栽培技术",{
            "weekIndex":4,"courseInfo":"11教234植物衰老生物学",{
            "weekIndex":5,"courseInfo":"11教234文献检索","periodTimesIndex":3
        }
    ]
}

其中 ，content内放到是本周课表：weekIndex是周几，periodTimesIndex是第几节课，现在筛选本周每天第一节课，并按照顺序weekIndex排列：

<div class="col" ng-repeat="FirstLesson in weekLesson.Content | filter:{periodTimesIndex:1}:false | orderBy:weekIndex">{{FirstLesson.courseInfo}}</div>
