Input text/dynamic text

[newbie50]

Hello,

I'm new to Actionscript 3.

I'm trying to get a user to enter his own numbers into an input text field.

And when he hits a button, it does a calculation ie. user input number x 5.

And that result shows up in a dynamic text field.

Is there a way to read a text input, do calculation and then take the result and turn it again into another string for the dynamic field?

Thanks.

Hi,

What you need is type-casting ( i.e. data type conversion)
Suppose you hv input textbox called 't'.

You can then do the following :
Number n = Number(t.text);
// process n
another_text.text = n + "";

This is AS2 code. Think you can able to convert in AS3.


var txtWidth = 100;
var txtHeight = 20;
var xPos = (Stage.width/2)-(txtWidth/2);
var yPos = 25;
var txt = this.createTextField("userTxt", this.getNextHighestDepth(), xPos, yPos, txtWidth, txtHeight);
txt.border = true;
txt.type = "input";
txt.restrict = "0-9";
var resultTxt = this.createTextField("result", this.getNextHighestDepth(), xPos, 0, txtWidth, txtHeight);
resultTxt.autoSize="Center";

var someListener:Object = new Object();
someListener.onSetFocus = function() {
if (userTxt.text == "Enter ID") {
userTxt.text = "";
}
};

Selection.addListener(someListener);

txt.onChanged = function() {
var maxLen = 5;
if (userTxt.text.length>maxLen) {
userTxt.text = userTxt.text.substr(0, maxLen);
}
};

//--------------------------------------------------//

var clip = this.createEmptyMovieClip("btn", this.getNextHighestDepth());
clip.beginFill(0x999999,100);
clip.moveTo(0,0);
clip.lineTo(100,0);
clip.lineTo(100,20);
clip.lineTo(0,20);
clip.lineTo(0,0);
clip.endFill();
clip._x = 50;
clip._y = 50;
clip.onRelease = function() {
clip._focusrect = false;
Selection.setFocus(clip);
if (userTxt.text != "") {
resultTxt.text=(userTxt.text*5);
} else {
userTxt.text = "Enter ID";
}
};

Hello,

Thanks for the replies but not quite sure I understand.

Here's what I have so far.

inputBox.restrict="0-9\\.\\";
stage.focus = inputBox;

some_btn.addEventListener(MouseEvent.CLICK, userInput);
function userInput(evt:MouseEvent):void {
dynamicBox.text = (Number(inputBox * 2)).toString();

}

[marlopax]

inputBox.restrict="0-9\\.\\";
stage.focus = inputBox;
some_btn.buttonMode=true;
some_btn.addEventListener(MouseEvent.CLICK, userInput);
function userInput(evt:MouseEvent):void {
dynamicBox.text = (Number(inputBox.text)*2).toString();
}

This will do the same as I post the previous code in AS2.
If you just paste the code in an empty AS2 fla and test, you must understand what it is.

Thanks marlopax. It's just that I'm using Actionscript 3 and not 2. And I've been told the two are completely different.

Hello,

I've got the following to work without any error messages. Do you see any coding that should be cleaned up or done in a better way?
Thanks for the help.


inputBox.restrict="0-9\\.\\";
inputBox.text = "0.00";
stage.focus = inputBox;
outputBox.text = "0.00";

one_btn.addEventListener(MouseEvent.CLICK, userOne);
function userOne(evt:MouseEvent):void {
outputBox.text = (Number(inputBox.text) * 2 * 3).toString();
}

two_btn.addEventListener(MouseEvent.CLICK, userTwo);
function userTwo(evt:MouseEvent):void {
outputBox.text = (Number(inputBox.text) * 2 * 4).toString();
}
