Question

Cautionary alert while displaying a data binding from a controller in AngularJS

Adding a numerical value to the controller:

this.myValue = Number(elem.toFixed(2));

Then placing it inside an input form:

    <input class="my-input"
           type="number"
           value={{$ctrl.myValue}}
        ...
   >

Although the value is correct and displayed as expected on the screen, there's a warning message in the console:

The specified value "{{$ctrl.myValue}}" is not a valid number. The value must match to the following regular expression: -?(\d+|\d+.\d+|.\d+)([eE][-+]?\d+)?

Any suggestions on how to remove this warning?

<input type="text" ng-model="myValue" >

Afterward, you can easily access it within the controller using $scope.myValue.

In accordance with the recommendation of Elena Kuznetsova, changing the variable value to an ng-model and replacing curly brackets with quotes will result in the warning message disappearing.


    <input class="custom-input"
           type="text"
           ng-model="$ctrl.customValue"
