基础的暂且不提。这个干啥的大家应该都知道。

1.自定义快捷选中日期：

data -- return中配置

pickerDates: {
    shortcuts: [
        {
            text: '今日',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        },
        {
            text: '近三日',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                start.setTime(start.getTime() - 3600 * 1000 * 24 * 2);
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        },
        {
            text: '近一周',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                start.setTime(start.getTime() - 3600 * 1000 * 24 * 6);
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        },
        {
            text: '近一个月',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                start.setTime(start.getTime() - 3600 * 1000 * 24 * 29);
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        },
        {
            text: '近三个月',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                start.setTime(start.getTime() - 3600 * 1000 * 24 * 89);
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        },
        {
            text: '近半年',
            onClick(picker) {
                const end = new Date();
                const start = new Date();
                start.setTime(start.getTime() - 3600 * 1000 * 24 * 182);
                picker.$emit('pick', [start.setHours(0, 0, 0, 0), end]);
            }
        }
    ]
}

2.如果只是要求不能选中今日之后的日期的话

pickerDates: {  //日期禁止选择今天之后的
    disabledDate(time) {
        return time.getTime() > Date.now() - 8.64e7;
    },
},
