Client side Drop down validation using jQuery.
For the textbox MVC will write JavaScript
for Required, RegularExpression
& StringLength attributes but there is no built-in method to validate a
drop down menu, we need to define our own method.
First we need to define a method to
validate dropdown control and define rules for each dropdown controls.
To display your error message still you
need to defile required attribute on your property and include validation
summery on your page. E.g.
jQuery.validator.addMethod(
"selectNone",
function(value, element) {
if (element.value == "")
{
return false;
}
else return true;
},
"Please select an option."
);
$(document).ready(function() {
$("#form0").validate({
rules: {
"Title.TitleID": {
selectNone: true
},
"SecretQuestion.IntCode":{
selectNone: true
}
}
});
});
