JS中Date与String的相互转换

1- Date -> String

new Date().toLocaleDateString();  ==> 2017/4/15

2- Date -> "2017-04-15"

                varyear =new Date().getFullYear();//获取完整的年份(4位,1970-????)

               var month = new Date().getMonth() + 1;//获取当前月份(0-11,0代表1月)

               var day = new Date().getDate();//获取当前日(1-31)

               if (month < 10) {

                    month ="0" + month;

                }

               if (day < 10) {

                    day ="0" + day;

                }

var dateString = year +"-" + month + "-" + day;

==> 2017-04-15

3- JsonDate -> Date

    var date =  newDate(parseInt(jsonDate.replace("/Date(","").replace(")/",""), 10));
