jQuery.Model.static.attributes  attribute     

Attributes contains a list of properties and their types for this model. You can use this in conjunction with jQuery.Model.convert to provide automatic type conversion.

The following converts dueDates to JavaScript dates:

$.Model("Contact",{
  attributes : { 
    birthday : 'date'
  },
  convert : {
    date : function(raw){
      if(typeof raw == 'string'){
        var matches = raw.match(/(\d+)-(\d+)-(\d+)/)
        return new Date( matches[1], 
                 (+matches[2])-1, 
                matches[3] )
      }else if(raw instanceof Date){
          return raw;
      }
    }
  }
},{})
