Angularjs 手写日历的实现代码（不用插件）

<div class="plan_content_box" data-ng-init="showTime()">    <div class="field" style="width: 100%;">     <span class="field_label" style="width: 100%;text-align: center;">      <select id="time_year" ng-change="change_year(select_year)" ng-model="select_year" ng-options="x.id as x.value for x in all_year">       <!--<option value="1900">1900</option>-->      </select> 年      <select id="time_month" ng-change="change_month(select_month)" ng-model="select_month" ng-options="x.id as x.value for x in all_month">       </select> 月 {{active_day}} 日     </span>    </div>        <table class="table table-bordered hover_td" style="border: none;">     <tr id="float_td">      <td>星期日</td>      <td>星期一</td>      <td>星期二</td>      <td>星期三</td>      <td>星期四</td>      <td>星期五</td>      <td>星期六</td>      <td ng-repeat="day in days track by $index" ng-click="change_day(day)"        ng-class="{true:'active',false:''}[day==active_day]" ng-model="day">{{day}}</td>     </tr>    </table>   </div>

 //  创建日历    $scope.all_year = [];    $scope.all_month = [];  $scope.showTime = function() {   //在select中填入年份   for(var year = 2016; year < 2050; year++) {    var obj_1 = {'value': year, 'id': year}    $scope.all_year.push(obj_1);   }      //在select中填入月份   for(var month = 1; month < 13; month++) {    var obj_2 = {'value': month, 'id': month}    $scope.all_month.push(obj_2);   }   console.log($scope.all_year)   //初始化显示 当前年和月   $scope.show_now()        }  //当select的选中的option发送变化的触发的事件  $scope.change_year = function(data) {   $scope.showDays(data, $scope.select_month)  }  $scope.change_month = function(data) {   $scope.showDays($scope.select_year, data)     }  //返回指定的月份的天数 月份1-12  $scope.calDays = function (year, month) {   return new Date(year, month, 0).getDate();  }  $scope.days = [];  //展示指定的年和月的所有日期  $scope.showDays = function(year, month) {   $scope.days = [];      //得到表示指定年和月的1日的那个时间对象   var date = new Date(year, month - 1, 1);         //1.先添加响应的空白的li:这个月1号是星期几，就添加几个空白的li   var dayOfWeek = date.getDay(); //得到1日是星期几   for(var i = 0; i < dayOfWeek; i++) {    $scope.days.push("");   }         //计算一个月有多少天   var daysOfMonth = $scope.calDays(year, month);   //2. 从1号开始添加li   for(var i = 1; i <= daysOfMonth; i++) {    $scope.days.push(i)   }  }    $scope.active_day = ''  $scope.select_year = ''  $scope.select_month = ''  //初始化显示 当前年和月  $scope.show_now = function() {   var now = new Date();//   $("#time_year").val(now.getFullYear());//   $("#time_month").val(now.getMonth() + 1);    $scope.active_day = now.getDate();   $scope.select_year = now.getFullYear();   $scope.select_month = now.getMonth() + 1;   $scope.showDays($scope.select_year, $scope.select_month)  }        $scope.change_day = function(day){   $scope.active_day = ""   $scope.active_day = day  }  // 以上是创建日历
