Learn backbone.js tutorial from scratch for beginners(Part 13) Model Validation in backbone.js

1. validate(),
2. isValid(),
3. validationError


validate()
In model it provides rules to validate model.

isValid()
It checks that model has passed its all rules or not.

validationError
if isValid() returns false, means model contains errors, so to see those errors we use validationError.

Have a look the complete code,
[script]
initialize:function(){
},
validate:function(attribute){
return "Age should not be negative";
}

return "Name is needed";
}
}
});

var mymodel = new MyModel({
name:"Sanjay Kumar",
team:"Profotech Solutions",
age:10
});

model: mymodel,
initialize:function(){
},
render:function(){

}else{
}

}
});

var myViewObj = new MyView();

[/script]
