  • javascript中怎样将字符串“04/06/2011”的日期加1天,返回成字符串“04/06/2011”格式的字符串

    Date.prototype.pattern=function(fmt) {          //日期格式化函数
        var o = {       
        "M+" : this.getMonth()+1, //月份       
        "d+" : this.getDate(), //日       
        "h+" : this.getHours() == 0 ? 12 : this.getHours(), //小时       
        "H+" : this.getHours(), //小时       
        "m+" : this.getMinutes(), //分       
        "s+" : this.getSeconds(), //秒       
        "q+" : Math.floor((this.getMonth()+3)/3), //季度       
        "S" : this.getMilliseconds() //毫秒       
        };       
        var week = {       
        "0" : "\u65e5",       
        "1" : "\u4e00",       
        "2" : "\u4e8c",       
        "3" : "\u4e09",       
        "4" : "\u56db",       
        "5" : "\u4e94",       
        "6" : "\u516d"      
        };       
        if(/(y+)/.test(fmt)){       
            fmt=fmt.replace(RegExp.$1, (this.getFullYear()+"").substr(4 - RegExp.$1.length));       
        }       
        if(/(E+)/.test(fmt)){       
            fmt=fmt.replace(RegExp.$1, ((RegExp.$1.length>1) ? (RegExp.$1.length>2 ? "\u661f\u671f" : "\u5468") : "")+week[this.getDay()+""]);       
        }       
        for(var k in o){       
            if(new RegExp("("+ k +")").test(fmt)){       
                fmt = fmt.replace(RegExp.$1, (RegExp.$1.length==1) ? (o[k]) : (("00"+ o[k]).substr((""+ o[k]).length)));       
            }       
        }       
        return fmt;       

     
     
    var myDate=new Date("04/06/2011")
    myDate.setDate(myDate.getDate()+1)
    alert(myDate.pattern('MM/dd/yyyy'));
