vue 倒计时60s 案例判断与验证码判断

		 getCode(formData){
            if (!this.timer) {
                this.count = TIME_COUNT;
                this.show = false;
                this.timer = setInterval(() => {
                  if (this.count > 0 && this.count <= TIME_COUNT) {
                    this.count--;
                  } else {
                    this.show = true;
                    clearInterval(this.timer);
                    this.timer = null;
                  }
                }, 1000)
              }
        } 

//逻辑判断

    const TIME_COUNT = 60;

                code:"",
                show: true,
                count: '',
                timer: null,

			<button @click="getCode(formData)" class="getCode" :disabled="!show" :class="{count:!show}" >
		         <span v-show="show">获取验证码</span>
		         <span v-show="!show" >{{count}} s</span>
		     </button>
