AngularJs验证重复密码的方法(两种)

密码

重复密码

两次密码不一致

/*JS*/
app.controller("main",function($scope){
$scope.submit=function(ngFormController){
return ngFormController.$invalid; /*valid的取反*/
};
});

/*指令创建*/
app.directive('equals',function(){
return{
require:'ngModel',
link:function(scope,elm,attrs,ngModelCtrl){
function validateEqual(myValue){
var valid = (myValue === scope.$eval(attrs.equals));
ngModelCtrl.$setValidity('equal',valid);
return valid &＃63; myValue : undefined;
}
ngModelCtrl.$parsers.push(validateEqual);
ngModelCtrl.$formatters.push(validateEqual);
scope.$watch(attrs.equals,function(){
ngModelCtrl.$setViewValue(ngModelCtrl.$viewValue);
})
}
}
});
