export default {
data () {
return {
value : null
}
},
methods: {
onCreate: function (event) {
var numericObj=document.getElementById("numeric").ej2_instances[0];
// prevents nullable value during initialization
if (numericObj.value==null) {

}
}
onBlur: function(args) {
if(args.value == null) {
numeric.value = 0;
}
