使用angular写了一个三级联动的生日插件

王者荣耀深似海啊，感觉自己的博客都要长满野草了，最近菁英汇的1.0.2版本已经开发完了，就等着联调，冒烟测试了。写了一个生日联动插件具体的效果是这样的

 

 

具体的数据

我取得数据是今年的数据，如果是想要做三级联动的日期插件，改一下时间就好了

var app=angular.module("dataPicker",[])

 

    app.factory('dataPicker', ['$http', '$q', function ($http, $q) {
        return {
            query: function () {
                var lengthYear=100;
                var dataPicker={
                    month:[],
                    year:[],
                    day:[]
                };
                var data = new Date();
                var nowyear = data.getFullYear();
                for(var i=nowyear,j=0; i>nowyear-lengthYear;i--,j++){
                    dataPicker.year[j]=i;
                }
                for(var i=0;i<=11;i++){
                    if(i<9){
                        dataPicker.month[i]='0'+(i+1);
                    }else{
                        dataPicker.month[i]=String(i+1);
                    }
                }
                return dataPicker;
            }
        }
    }])

 

directive插件的主要内容

app.directive('selectDatepicker', function ($http,dataPicker) {
        return {
            restrict: 'EAMC',
            replace: false,
            scope: {
                birthday: '=birthday'
            },
            transclude: true,
