日期三联控件

运用Seajs模块写的一个三联日期选择控件，可以通过配置显示页面元素信息

define(function (require, exports, module) {
    'use strict';

    var $ = require('zepto');
    require('./dateSelect.css');

    var config = {
        "dateSelect":".dateSelect",
        "year_box": 'J_select_year',      // 年对象
        "month_box": 'J_select_month',     // 月对象
        "day_box": 'J_select_day',       // 日对象
        "hiddenName":"hiddenName",//隐藏的日期传值
        "birthday":0,            //日期默认值
        "year": 0,              // 年
        "month": 0,              // 月
        "day": 0,              // 日
        "min_year": 0,              // 最小年份
        "max_year": 0,              // 最大年份
        "onChange": null            // 日期改变时执行
    };
    
    var DateSelect = function () {
        var self = this;
        self.config = config;    
    }

　　调用方法

define(function (require, exports, module) {
    'use strict';
    var $ = require('zepto');
    var DateSel=require('./DateSelectMobile');
    var dateSel=new DateSel();

    var birthday = "";
    var d = new Date(birthday);
    var year = d.getFullYear() || 0;
    var month = d.getMonth() + 1 || 1;
    var day = d.getDate() || 1;

    if(birthday=="")
    {
        birthday=year+"-"+month+"-"+day;
        $("#birthday").val(year+"-"+month+"-"+day);
    }

    dateSel.init({
        "dateSelect":".dateSelect1",
        "year_box": 'J_year',      // 年对象
        "month_box": 'J_month',     // 月对象
        "day_box": 'J_day',       // 日对象
        "hiddenName":"birthday",
        "birthday": birthday,
        "year": year,           // 年
        "month": month,          // 月
        "day": day,            // 日
        "min_year": 1970,           // 最小年份
        "max_year": new Date().getFullYear()// 最大年份
    });

    dateSel.start();
});
