Minimum characters allowed, textfield.

[vvvverT]

Good afternoon users, how can I be limiting the minimum characters allowed in a textfield? The action is executed from a button, however, I like to put a minimum of four characters to be able to button selection.

Can anybody help me? I am grateful in advance for attention!

The following hides the button until there are 4 or more characters in the textfield...  you can change it to use the mouseEnabled property instead of the visible property if you don't want to hide the button.

btn.visible = false;

tf_1.text = "";

tf_1.addEventListener(Event.CHANGE, checkText);

function checkText(evt:Event){

     if(tf_1.text.length > 3){

         btn.visible = true;

     } else {

         btn.visible = false;

     }

}

else if(tf_1.text.length > 3) {
  trace("Fill out the field");
}

Hello Ned, this part of the code I'm saying.

I would like to add this condition, perhaps with a return not to advance to the following conditions. Thus, if the user types something with less than 3 characters will not advance.

However, when I try for a return always the error by adding a "return 1;" the end condition.

Would you help me?

Your explanation is not clear to me, nor is the code you show.  If the text length is > 3 then you should not be telling someone to fiull out the field... they have done that.

Showing just a portion of the code does not explain what you have tried.  Please show all of the code that is giving you a problem.  The code that I showed works when I have a textfield and a button.

calcular.addEventListener(MouseEvent.CLICK, resolver);
var num:Number;
function resolver(Event:MouseEvent): void {
  num = 0;
  num = Number(tf_1.text);
  if(num % 400 == 0 || num % 4 == 0 && num % 100 != 0) {
  trace("Yes!");
  gotoAndStop(44);
  }
  else {
  trace("No!");
  gotoAndStop(45);
  }
}

This is the elaborate code, however, like to add a condition that if the user to enter a minimum number of four characters, the operation is not performed, giving a return not to proceed further.

Would you help me?

calcular.addEventListener(MouseEvent.CLICK, resolver); 

var num:Number; 

function resolver(event:MouseEvent): void { 

   if(tf_1.text.length > 4){

       num = Number(tf_1.text); 

       if(num % 400 == 0 || num % 4 == 0 && num % 100 != 0) { 

           trace("Yes!"); 

           gotoAndStop(44); 

       } else { 

           trace("No!"); 

           gotoAndStop(45); 

       }

   } else {

        // do whatever you mean by "giving a return"

   }

}
