the backend asked to make the selection of this date range a required entry in the form, but did not find the corresponding check in element-ui. I tried to fill in required and message, in rules, but when I did not select a time, the word "Please choose a time" did not appear on the page. Can anyone help me answer it? thank you
you can customize a test
data(){
var validDate = (rule,value,callback) => {
if(!value[0] || !value[1]){
callback(new Error(""))
}else{
callback()
}
}
return {
rules: {
daterange: [{
validator: validDate,
trigger: 'blur'
}]
}
}
}you can also do more complex verification, such as whether daterange is an array type, and validation of date intervals
http://element-cn.eleme.io/-sharp/.
Form component provides the function of form validation by passing in the agreed validation rules through the rules attribute and setting the prop property of Form-Item to the field name to be verified. Take a closer look at the document
