angular typescript获取格式化日期及前后范围日期

1：TypeScript 获取时间戳：

Date.parse(new Date().tostring());

2：TypeScript获取格式化日期:

static getNowDate(): string {const date = new Date();let month: string | number = date.getMonth() + 1;let strDate: string | number = date.getDate();if (month <= 9) {month = "0" + month;}if (strDate <= 9) {strDate = "0" + strDate;}return date.getFullYear() + "-" + month + "-" + strDate + " "+ date.getHours() + ":" + date.getMinutes() + ":" + date.getSeconds();
}

3：日期工具类：

dateTime.ts:formatDate(){// 格式化日期，获取今天的日期const Dates = new Date(time);const year: number = Dates.getFullYear();const month: any = (Dates.getMonth() + 1) < 10 ? '0' + (Dates.getMonth() + 1) : (Dates.getMonth() + 1);const day: any = Dates.getDate() < 10 ? '0' + Dates.getDate() : Dates.getDate();const hours = Dates.getHours() < 10 ? '0' + Dates.getHours() : Dates.getHours();const minutes = Dates.getMinutes() < 10 ? '0' + Dates.getMinutes() : Dates.getMinutes();const seconds = Dates.getSeconds() < 10 ? '0' + Dates.getSeconds() : Dates.getSeconds();//返回数据格式return year + '-' + month+ '-' + day + ' ' + hours + ':' + minutes + ':' + seconds;
} 

4.前后范围方法

	/*** @param {number} range* @param {string} [type]* @memberOf VehicleOverviewComponent* @description 获取今天及前后天*/getRangeDate( range: number, type?: string ) {const formatDate = ( time: any ) => {// 格式化日期，获取今天的日期const Dates = new Date( time );const year: number = Dates.getFullYear();const month: any = ( Dates.getMonth() + 1 ) < 10 ? '0' + ( Dates.getMonth() + 1 ) : ( Dates.getMonth() + 1 );const day: any = Dates.getDate() < 10 ? '0' + Dates.getDate() : Dates.getDate();return year + '-' + month + '-' + day;};const now = formatDate( new Date().getTime() ); // 当前时间const resultArr: Array = [];let changeDate: string;if ( range ) {if ( type ) {if ( type === 'one' ) {changeDate = formatDate( new Date().getTime() + ( 1000 * 3600 * 24 * range ) );console.log( changeDate );}if ( type === 'more' ) {if ( range < 0 ) {for ( let i = Math.abs( range ); i >= 0; i-- ) {resultArr.push( formatDate( new Date().getTime() + ( -1000 * 3600 * 24 * i ) ) );console.log( resultArr );}} else {for ( let i = 1; i <= range; i++ ) {resultArr.push( formatDate( new Date().getTime() + ( 1000 * 3600 * 24 * i ) ) );console.log( resultArr );}}}} else {changeDate = formatDate( new Date().getTime() + ( 1000 * 3600 * 24 * range ) );console.log( changeDate );}}}

调用及结果
range参数支持正负数，里面也加了判断;
type【为可选参数】有两种，一个是字符串one，一个是more；前者返回一个指定的日期；后者返回一个排序好的范围getRangeDate( -6 );// 结果：2017-02-09getRangeDate( -6, 'one' );// 结果：2017-02-09getRangeDate( -6, 'more' );// 结果// ["2017-02-09", "2017-02-10", "2017-02-11", "2017-02-12", "2017-02-13", "2017-02-14", "2017-02-15"]
