How to hide error message in vue js after validation is true?

Actually my problem I am checking when a particular value is valid through v-on:input. If, the value is invalid I get the response as "invalid data" and i display the same. But, when the value becomes valid, the "invalid data" is not hiding. How to I able to do so.

My code is

methods:
checkLimit: function ()
var vm = this;
data = ;
if (this.no != '') data['no'] = this.no;
$.ajax(
url: "doc/checkNumber",
method: "POST",
data: data,
dataType: "JSON",
success: function (e)
if (e.status == true)

else
console.log(e.msg);
vm.error = e.msg;


,
);
,



So if status is false, I am showing as <input type="text" class="form-control" v-model="orno" required="" v-on:input="checkLimit" maxlength="3"><p>error</p>. But when Status is true the error message is still present. How can I update based on the change?

<input type="text" class="form-control" v-model="orno" required="" v-on:input="checkLimit" maxlength="3"><p>error</p>

You should set the error to '' when the e.status is true. Like this

error

''

e.status

success: function (e)
if (e.status == true)
vm.error = '';
else
console.log(e.msg);
vm.error = e.msg;

,


Simple: in checkLimit do vm.error=null on success. Then in the template do <p v-if="error">error</p>.

checkLimit

vm.error=null

<p v-if="error">error</p>

Since in vue all data is reactive p will disappear when error is falsy.
