1.选择月份范围

代码如下：

   <el-date-picker v-model="value" type="monthrange" align="right" unlink-panels range-separator="至"
            start-placeholder="开始月份" end-placeholder="结束月份" :picker-options="pickerOptions">
          </el-date-picker>

 pickerOptions: {
        shortcuts: [{
          text: '本月',
          onClick(picker) {
            picker.$emit('pick', [new Date(), new Date()]);
          }
        }, {
          text: '上个月',
          onClick(picker) {
            const end = new Date();
            const start = new Date();
            start.setMonth(start.getMonth() - 1);
            picker.$emit('pick', [start, end]);
          }
        }, {
          text: '上季度',
          onClick(picker) {
            const end = new Date();
            const month = end.getMonth();
            let start = new Date();

            // 计算上一个季度的开始和结束日期
            if (month >= 0 && month <= 2) {  // 第一季度
              start.setFullYear(end.getFullYear() - 1, 9, 1);
              end.setFullYear(end.getFullYear() - 1, 11, 31);
            } else if (month >= 3 && month <= 5) {
              start.setFullYear(end.getFullYear(), 0, 1);
              end.setFullYear(end.getFullYear(), 2, 31);
            } else if (month >= 6 && month <= 8) {
              start.setFullYear(end.getFullYear(), 3, 1);
              end.setFullYear(end.getFullYear(), 5, 30);
            } else {  // 第四季度
              start.setFullYear(end.getFullYear(), 6, 1);
              end.setFullYear(end.getFullYear(), 8, 30);
            }

            picker.$emit('pick', [start, end]);
          }
        }]
      },
      value: ''

2.选择日期范围

代码如下：

        <el-date-picker v-model="value" type="daterange" align="right" unlink-panels range-separator="至"
          start-placeholder="开始日期" end-placeholder="结束日期" :picker-options="pickerOptions">
        </el-date-picker>

      pickerOptions: {
        shortcuts: [{
          text: '本月',
          onClick(picker) {
            picker.$emit('pick', [new Date(), new Date()]);
          }
        }, {
          text: '上个月',
          onClick(picker) {
            const end = new Date();
            const start = new Date();
            start.setMonth(start.getMonth() - 1);
            start.setDate(1); 
            end.setMonth(end.getMonth() - 1);
            end.setMonth(end.getMonth() + 1, 0);
            picker.$emit('pick', [start, end]);
          }
        }, {
          text: '上季度',
          onClick(picker) {
            const end = new Date();
            const month = end.getMonth();
            let start = new Date();

            if (month >= 0 && month <= 2) {
              start.setFullYear(end.getFullYear() - 1, 9, 1);
              end.setFullYear(end.getFullYear() - 1, 11, 31);
            } else if (month >= 3 && month <= 5) {
              start.setFullYear(end.getFullYear(), 0, 1);
              end.setFullYear(end.getFullYear(), 2, 31);
            } else if (month >= 6 && month <= 8) {
              start.setFullYear(end.getFullYear(), 3, 1);
              end.setFullYear(end.getFullYear(), 5, 30);
            } else {
              start.setFullYear(end.getFullYear(), 6, 1);
              end.setFullYear(end.getFullYear(), 8, 30);
            }

            picker.$emit('pick', [start, end]);
          }
        }]
      },
      value: '',
