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
        },
        {
            "weekIndex":1,
            "courseInfo":"11教232食品安全学",
            "periodTimesIndex":4
        },
        {
            "weekIndex":2,
            "courseInfo":"11教232乳制品工艺学",
            "periodTimesIndex":1
        },
        {
            "weekIndex":2,
            "courseInfo":"11教232大学英语(二)",
            "periodTimesIndex":2
        },
        {
            "weekIndex":2,
            "courseInfo":"11教232计算机基础(一)",
            "periodTimesIndex":4
        },
        {
            "weekIndex":3,
            "courseInfo":"11教234人体解剖学",
            "periodTimesIndex":2
        },
        {
            "weekIndex":3,
            "courseInfo":"11教234植物资源学",
            "periodTimesIndex":3
        },
        {
            "weekIndex":3,
            "courseInfo":"11教234花卉栽培技术",
            "periodTimesIndex":4
        },
        {
            "weekIndex":4,
            "courseInfo":"11教234植物衰老生物学",
            "periodTimesIndex":2
        },
        {
            "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>
