element-ui 通过按钮式触发日期选择器
作者：做一个有用的阿吉
ElementUI是Vue.js的一套组件库,其日期时间选择器默认是通过点击输入框来触发,本文介绍了如何自定义触发日期选择器,同时隐藏输入框,通过编写一个自定义组件CustomDatePicker.vue,可以实现点击按钮来触发日期选择器
element-ui 通过按钮式触发日期选择器
写在前面
需求：elementui中日期时间选择器，目前只能通过点击input输入框触发日期选择器，我希望能通过其他方式触发日期选择器同时把input输入框去掉，如点击按钮
1. 自定义的日期时间组件CustomDatePicker.vue
<template>
<div class="date-input">
<el-input
v-model="startDateStr"
:placeholder="$t('task.taskStartTime')"
type="text"
clearable
class="date-input-field"
@input="validateDate"
/>
<span class="line"></span>
<el-input
v-model="endDateStr"
:placeholder="$t('task.taskFinishTime')"
type="text"
clearable
class="date-input-field"
@blur="validateDate"
/>
<div class="icon-container" @click="toggleDatePicker">
<i class="el-icon-date" style="font-size: 24px;"></i>
</div>
<el-date-picker
style="
position: absolute;
z-index: -100;
top: 15px;
left: -178px;
transform: scale(0.1);
"
size="mini"
v-model="selectedDateRange"
:editable="false"
type="datetimerange"
@change="onDateChange"
ref="timePick"
value-format="yyyy-MM-dd HH:mm:ss"
/>
</div>
</template>
<script>
export default {

element UI时间组件两种使用方式
加油，新时代打工！
组件官网：https://element.eleme.cn/
先上效果图，如下：
第一种实现方式
<div class="app-container">
<el-form
ref="submitForm"
:model="submitForm"
class="form-item table"
label-width="80px"
label-position="left"
:inline="true"
>
<el-form-item label="开始日期" prop="startDate">
<el-date-picker
v-model="submitForm.startDate"
type="date"
placeholder="请输入开始日期"
value-format="yyyy-MM-dd"
:picker-options="pickerOptionsStart"
></el-date-picker>
</el-form-item>
<el-form-item label="结束日期" prop="endDate">
<el-date-picker
v-model="submitForm.endDate"
type="date"
placeholder="请输入开始日期"
value-format="yyyy-MM-dd"
:picker-options="pickerOptionsEnd"
></el-date-picker>
</el-form-item>
<el-form-item>
<el-button type="primary" icon="el-icon-search" size="mini" @click="handleQuery">搜索</el-button>
<el-button icon="el-icon-refresh" size="mini" @click="resetQuery">重置</el-button>
</el-form-item>
</el-form>
</div>
<script>
export default {
name: 'statisticsCountyCrops',
data() {
return {
loading: true,
// 开始结束日期限制
pickerOptionsStart: {
disabledDate: time => {
if (this.submitForm.endDate) {
return (
time.getTime() >= new Date(this.submitForm.endDate).getTime()
);
}
}
},
// 结束日期限制
pickerOptionsEnd: {
disabledDate: time => {
if (this.submitForm.startDate) {
return (
time.getTime() <= new Date(this.submitForm.startDate).getTime()
);
}
}
},
submitForm: {
startDate: '',
endtDate: ''
},
};
},
methods: {
/* get请求 对象参数*/
getList(){
statisticsCountyCrops(this.submitForm).then(res =>{
this.dataList = res.data;
this.loading = false;
}).catch(err =>{
console.error(err)
this.loading = false;
})
},
/** 搜索按钮操作 */
handleQuery() {
this.getList();
},
/** 重置按钮操作 */
resetQuery() {
this.daterangeCreateTime = [];
this.resetForm("submitForm");
},
},
};
</scrpit>第二种实现方式
<el-form-item label="查询范围">
<el-date-picker
v-model="daterangeCreateTime"
style="width: 240px"
value-format="yyyy-MM-dd"
type="daterange"
range-separator="-"
start-placeholder="开始日期"
end-placeholder="结束日期"
></el-date-picker>
</el-form-item>
<script>
export default {
data() {
return {
daterangeCreateTime: [],
queryParams:{},
}
},
this.queryParams = {};
if (null != this.daterangeCreateTime && '' != this.daterangeCreateTime) {
this.queryParams["startDate"] = this.daterangeCreateTime[0];
this.queryParams["endDate"] = this.daterangeCreateTime[1];
}
}
