Knockout.js验证错误计数未设置

Question

I'm using the knockout.js validation plugin and it's working perfectly for a validating a form that I'm using, however, it doesn't appear to be tracking the number of errors. When I submit the form, if it detects any errors it shouldn't submit, but it is submitting.

function EntryViewModel(fullName, addressLine1, addressLine2, city, state, ZIP, email) {

    //viewmodel code here
    //the validation messages are being set on my form so i figure listing all of the rules is not necessary

  self.submitOrder = function(){ 
     alert(EntryViewModel.errors().length); //displays 0
     if (EntryViewModel.errors().length == 0) {
          //submit
     }
     else{
         alert('Please fix errors before submitting');
     }
   }
 }

 EntryViewModel.errors = ko.validation.group(EntryViewModel);  //I also tried putting this in my viewmodel and it didn't do anything

I could be approaching this entirely wrong, I'm just basing it off of this fiddle that is linked from the Github page for the project

Answer 1

have you tried changing submitOrder to reference self instead of the function name

self.submitOrder = function(){ 
    alert(self.errors().length); //displays 0
    if (self.errors().length == 0) {
      //submit
    }
    else{
        alert('Please fix errors before submitting');
    }
}

and inside the function, make the group call

self.errors = ko.validation.group(self);  

assigning to self.errors is actually redundant. the group call will create an errors observable on self
