[JavaScript知识库]vue时间倒计时（时间自己设定）

直接上代码

<div class="daojishi">
				{{fen}} : {{miao}}
			</div>

dao: null,
fen: "00",
miao: "00",

daojishi() {
				this.fen = "10"
				this.miao = "00"
				clearInterval(this.dao);
				this.dao = setInterval(() => {
					if (this.miao == 0) {
						if (parseInt(this.fen) < 11) {
							this.fen = "0" + (parseInt(this.fen) - 1).toString()
						} else {
							this.fen = parseInt(this.fen) - 1
						}
						this.miao = 60
					}
					if (parseInt(this.miao) < 11) {
						this.miao = "0" + (parseInt(this.miao) - 1).toString()
					} else {
						this.miao = parseInt(this.miao) - 1
					}
					if (this.miao == 0 && this.fen == 0) {
						clearInterval(this.dao);
					}
				}, 1000)
			},

fen 和 miao 参数自己定义多少

结束！
