ElemenUI时间日期组件

单个输入框的

<el-date-picker
   v-model="value1"
   type="date"
   placeholder="选择日期"
   :picker-options="pickerOptions0">
</el-date-picker>

情景1: 设置选择今天以及今天之后的日期

data (){
   return {
       pickerOptions0: {
          disabledDate(time) {
            return time.getTime() < Date.now() - 8.64e7;
          }
        },  
   }     
}

情景2: 设置选择今天以及今天以前的日期

data (){
   return {
       pickerOptions0: {
          disabledDate(time) {
            return time.getTime() > Date.now() - 8.64e6
          }
        },  
   }     
}

情景3: 设置选择今天之后的日期（不能选择当天时间）

data (){
   return {
       pickerOptions0: {
          disabledDate(time) {
            return time.getTime() < Date.now();
          }
        },  
   }     
}

情景4: 设置选择今天之前的日期（不能选择当天）

data (){
   return {
       pickerOptions0: {
          disabledDate(time) {
            return time.getTime() > Date.now();
          }
        },  
   }     
}

情景5: 设置选择三个月之前到今天的日期

data (){
   return {
       pickerOptions0: {
          disabledDate(time) {
            let curDate = (new Date()).getTime();
            let three = 90 * 24 * 3600 * 1000;
            let threeMonths = curDate - three;
            return time.getTime() > Date.now() || time.getTime() < threeMonths;;
          }
        },  
   }     
}

两个输入框

<el-date-picker
       v-model="value1"
       type="date"
       placeholder="开始日期"
       :picker-options="pickerOptions0">
</el-date-picker>
<el-date-picker
       v-model="value2"
       type="date"
       placeholder="结束日期"
       :picker-options="pickerOptions1">
</el-date-picker>

情景1: 限制结束日期不能小于开始日期（限制到期日期不能小于生产日期）

data(){
    return {
         pickerOptions0: {
                disabledDate: (time) => {
                    if (this.value2 != "") {
                        return time.getTime() < Date.now() || time.getTime() > this.value2;
                    } else {
                        return time.getTime() < Date.now();
                    }

                }
            },
            pickerOptions1: {
                disabledDate: (time) => {
                    return time.getTime() < this.value1 || time.getTime() > Date.now();
                }
            },
    }      
}

情景2: 限制结束日期不能大于开始日期（在许多博客上都看到了这个思路，个人觉得逻辑有点问题，结束日期应该大于开始日期，而不应该时不大于。）

data(){
        return {
             pickerOptions0: {
                    disabledDate: (time) => {
                        if (this.value2 != "") {
                            return time.getTime() > Date.now() || time.getTime() > this.value2;
                        } else {
                            return time.getTime() > Date.now();
                        }

                    }
                },
                pickerOptions1: {
                    disabledDate: (time) => {
                        return time.getTime() < this.value1 || time.getTime() > Date.now();
                    }
                },
        }      
    }
