Element-ui date and time control problem

it is OK to assign an initial value to the control, but there is no way to change the value through the control without reporting an error. It is very strange. I have been working on it for two days.

<el-date-picker
    v-model="dataForm.time = new Date("2018-08-08")"
    type="datetime"
    placeholder="">
</el-date-picker>

date cannot be selected, and the control will not disappear after clicking OK. Under normal circumstances, you should be able to select a date and time, and then click OK and the date and time should appear in the input box

Yes, silly boy.

your v-model binds an expression and executes dataForm.time = new Date ('2018-08-08') every time it is updated.

generally speaking, initial values are assigned directly to data

data(){
    return {
        dataForm:{
            time:new Date(),
        }
    }
}
