使用element UI的日期选择器时，默认显示当天日期
需求：输入框中要把当天日期显示在输入框中，并且传给后台的日期格式是2019-06-12。（如交易数据）
传给后台的时间格式为'2019-06-12'这样的格式，，这个很好实现，el-date-picker上添加value-format="yyyy-MM-dd"即可；
本来以为element UI中default-value设置之后，可以直接在输入框中显示，测试之后无用。最后通过下面的方法实现效果
<el-form-item label="交易数据">
<el-date-picker
type="date"
placeholder="选择日期"
v-model="searchFormField.date"
style="width: 100%;"
value-format="yyyy-MM-dd"
></el-date-picker>
</el-form-item>
methods: {
getNowTime() {
var now = new Date();
var year = now.getFullYear(); //得到年份
var month = now.getMonth(); //得到月份
var date = now.getDate(); //得到日期
month = month + 1;
month = month.toString().padStart(2, "0");
date = date.toString().padStart(2, "0");
var defaultDate = `${year}-${month}-${date}`;
this.$set(this.searchFormField, "date", defaultDate);
},
}
