切換不同的日期選擇器，定位錯誤

日期選擇器定位錯亂，切換其他的日期，如果是使用v-if來就行切換的話，切換的日期選擇器的定位會錯亂，變成left:0;top:0

<el-date-picker v-if="selectData === 'consecData'" type="daterange" class="datePicker" start-placeholder="起始日期"
			 end-placeholder="結束日期" v-model="modeStartDate1" range-separator="至" style="width: 216px; padding-top: 4px" size="mini"
			 value-format="yyyy-MM-dd" @change="dateChangePush"></el-date-picker>
			<el-date-picker v-else-if="selectData === 'consecWeek'" type="daterange" class="datePicker" start-placeholder="起始日期"
			 end-placeholder="結束日期" v-model="modeStartDate2" range-separator="至" style="width: 216px; padding-top: 4px" size="mini"
			 value-format="yyyy-MM-dd" @change="weekChangePush"></el-date-picker>
			 <!-- ="selectData === 'intervalData'" -->
			<el-date-picker v-else :disabled="!selectData" type="dates" v-bind:placeholder="placeholder"
			 v-model="modeStartDate3" style="width: 140px; font-size: 12px" size="mini" value-format="yyyy-MM-dd" @change="handleDateChangePush"></el-date-picker>

實際效果圖：


**解決方法：**不要使用v-if來顯示隱藏，使用v-show來對日期選擇器顯示隱藏

<el-date-picker v-show="selectData === 'consecData'" type="daterange" class="datePicker" start-placeholder="起始日期"
			 end-placeholder="結束日期" v-model="modeStartDate1" range-separator="至" style="width: 216px; padding-top: 4px" size="mini"
			 value-format="yyyy-MM-dd" @change="dateChangePush"></el-date-picker>
			<el-date-picker v-show="selectData === 'consecWeek'" type="daterange" class="datePicker" start-placeholder="起始日期"
			 end-placeholder="結束日期" v-model="modeStartDate2" range-separator="至" style="width: 216px; padding-top: 4px" size="mini"
			 value-format="yyyy-MM-dd" @change="weekChangePush"></el-date-picker>
			<el-date-picker v-show="selectData === 'intervalData'" :disabled="!selectData" type="dates" v-bind:placeholder="placeholder"
			 v-model="modeStartDate3" style="width: 140px; font-size: 12px" size="mini" value-format="yyyy-MM-dd" @change="handleDateChangePush"></el-date-picker>

效果圖：這樣切換的時候定位不會被置為0
