of course easy for you, just one line of code.

//build-in rule is't like the "required", it can't be translate such as required(...)
//you can see config.js to get details
SMValidator.setLang({number: 'please entry numbers', email: 'please entry a corrected email'});
                

numbers:

email :

your boss praise you for your job, but the new demand is here.
he want a validation with async, server end to tell you pass or fail.
do you want to give your boss a stick? but it's you job, come on baby~~

<input type="text" name="test5">
<script>
    new SMValidator('form', {
        fields: {
            test5: {
                required: true,
                async: 'please wait for validation...'
            }
        }
    });
    //"forceFlag" force result, 1-pass 2-fail
    //"asyncMessage" the message of async validation
    //remember "manul" in tutor1? there is SMValidator.validate(), too
    SMValidator.validate('[name="test5"]', {forceFlag: 2, asyncMessage: 'fail validate by server'});
</script>
                

later, your boss submit the form without entry any thing but it's submited successfully.
this bug will be given you to deal with without doubt.

//"submit" can prevent the default submit action.
new SMValidator('form', {
    submit: function(valid, form) {
        if(valid) form.submit();
    }
});
                

get here, may be you thought it's the end of your boss's demand. don't guess the thought of your boss forever. please see tutor4
