1.禁用之前的时间

<el-date-picker:picker-options="disableBeforePicker"disableBeforePicker: {disabledDate(time) {return time.getTime() < Date.now() - 8.64e7;},
},

2.选择开始时间之后，结束时间为开始时间之后的120分钟，他们的格式是yyyy-MM-dd HH:mm:ss

dataChange(value){if(value&&!this.endTime){const startDate = new Date(this.startTime.replace(/-/g, '/'));startDate.setMinutes(startDate.getMinutes() + 120);const year = startDate.getFullYear();const month = String(startDate.getMonth() + 1).padStart(2, '0');const day = String(startDate.getDate()).padStart(2, '0');const hours = String(startDate.getHours()).padStart(2, '0');const minutes = String(startDate.getMinutes()).padStart(2, '0');const seconds = String(startDate.getSeconds()).padStart(2, '0');this.endTime = `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;}
},

3.比较大小，获取当前时间

time(value, time) {const valueDate = new Date(value); // 将 value 转换为 Date 对象const timeDate = new Date(time); // 将 time 转换为 Date 对象return valueDate > timeDate; // 比较时间戳
},
isDate(value, time) {const valueDate = new Date(value); // 将 value 转换为 Date 对象const timeDate = new Date(time); // 将 time 转换为 Date 对象return valueDate >= timeDate; // 比较时间戳
},
getCurrentTime() {const now = new Date();const year = now.getFullYear();const month = String(now.getMonth() + 1).padStart(2, '0'); // 月份从 0 开始，需要 +1const day = String(now.getDate()).padStart(2, '0');const hours = String(now.getHours()).padStart(2, '0');const minutes = String(now.getMinutes()).padStart(2, '0');const seconds = String(now.getSeconds()).padStart(2, '0');return `${year}-${month}-${day} ${hours}:${minutes}:${seconds}`;
},
