The issue arises when using an Angular directive with an input type set as "number"

When the input type is text, the code below works perfectly fine. However, it fails to function when the input type is changed to number.

<div ng-app="myApp" ng-controller="myCtrl as model">
 <input type="text"  ng-model="cero" ng-decimal   >   
</div> 


angular
    .module("myApp",[])
    .controller('myCtrl', function($scope){
        var model=this;
    })
    .directive('ngDecimal', function ($parse) {
        var linkFunction =function(scope, element, attrs){     
            element.bind("keypress", function(event) {
                if(event.which === 13) {    
                    scope.$apply(function(){
                        scope.$eval(attrs.format, {'event': event});
                        if(scope.cero===undefined || scope.cero===''){
                            scope.cero="0.", 
                            event.preventDefault();
                        }else{

                        }
                    });
                }
            });
        };
        return{
            restrict : 'A',
            scope:{
                cero: '=ngModel'
            },
            link: linkFunction
        }
    });

I am seeking assistance in modifying the code to work with an input type of number instead of text. The code can also be found on CodePen.

Answer №1

Check out the updated code on this pen: http://codepen.io/anon/pen/QKOVkP?editors=1011

This solution works for numbers, but there is a constraint where you cannot assign

scope.cero = "0." // This is a string value

If you want to assign a minimum number instead, try replacing it with something like

scope.cero = parseFloat("0.01")  // Using parseFloat("0.") won't work

Answer №2

If the condition is false, then include the following steps:

scope.cero = parseFloat(scope.cero).toFixed(2);

Transform a string into a decimal value.
