Question

Does anyone know of a way to restrict a user from entering a number over 100 into a textinput field in flex?

i.e. a user can enter any number between and including 0-100 but not 101

Thanks in advance for any advice!

Answer 1

you have to check it manually, if this is your code

<input change='_handleTextChanges(event)' />

and this is the callback

function _handleTextChanges(evt:Event):void{
     var target:TextInput = evt.currentTarget as TextInput;
     if(!target) return;
     if(parseInt(target.text) > 100){
         Alert.show("You can't enter a number grater than 100");
         target.text = "100";
     }
     if(parseInt(target.text) < 0){
         Alert.show("You can't enter a number smaller than 0");
         target.text = "0";
     }
}

I haven’t tried it but it should work
