Get text from input TextFields by instance name

[dalvydasv27776233]

Hey, I have problem.. I know its simply thing, but 2 hours I cant do this:

for (var i = 0; i < REDquestionsLineArray.length; ++i) {

            var REDqText:TextField = new TextField();

            REDqText.name = "REDqestText" + ;

            window.addChild(REDqText);

            REDqText.text = String(REDquestionsLine);

            trace(REDqText.name);

            trace(REDqText.text);

}

var REDquestLine = [];

var saveREDquestionsLine:String

function save_REG_questions(e:MouseEvent):void{

    saveREDquestionsLine = "";

    for (var i = 0; i < REDquestionsLineArray.length; ++i) {

        REDquestLine = HOW TO GET TEXT STRVING FROM THEESE ("REDqestText" + ;)INPUT TEXTFIELDS?

        trace(REDquestLine);

    }

}

assuming that's all on the same timeline (ie, same scope), use

this['REDqestText'+i].text

[dalvydasv27776233]

It works, but Im getting old text. same as i set before.:\

But if I write something new i get old string.

[kglad]

then you're setting i incorrectly, calling that code at the incorrect time or overwriting textfield names.  use the trace function to debug.

[dalvydasv27776233]

Full code:

function show_RED_questions(){

    while (window.numChildren > 0) {

        window.removeChildAt(0);

    }

    trace("window clear");

    stage.addChild(window);

    var position2_y:Number = 44;

    var tarpas:int;

    tarpas = 220 / (REDquestionsLineArray.length-1);

    for (var i = 0; i < REDquestionsLineArray.length; ++i) {

        if(REDquestionsLine==null){

            //nedaryk nieko

        }else{

            trace("----++++++++++-----");

            var REDqText:TextField = new TextField();

            REDqText.name = 'REDqestText' + i;

            window.addChild(REDqText);

            var myFormat2:TextFormat = new TextFormat();

            myFormat2.size = 14;

            REDqText.defaultTextFormat = myFormat2;

            REDqText.height = 20;

            REDqText.type = "input";

            REDqText.border = true;

            REDqText.x = 292;

            REDqText.width = 600;

            REDqText.y = position2_y;

            REDqText.text = String(REDquestionsLine);

            position2_y = position2_y + tarpas;

            if(i == REDquestionsLineArray.length-1){

                window.addChild(save_button);

                save_button.x = 677;

                save_button.y = 344;

                save_button.addEventListener(MouseEvent.CLICK, save_REG_questions);

            }

        }

    }

}

var REDquestLine = [];

var saveREDquestionsLine:String

function save_REG_questions(e:MouseEvent):void{

    saveREDquestionsLine = "";

    for (var i = 0; i < REDquestionsLineArray.length; ++i) {

        REDquestLine = this['REDqestText' + i].text;

        saveREDquestionsLine = saveREDquestionsLine + REDquestLine + "|";

        trace(saveREDquestionsLine);

    }

}

Oh SORRy I dont get nothing just error;

TypeError: Error #1010: A term is undefined and has no properties.

if that else branch is executing, you have a problem in your logic.  you probably want that if-statement in your other function, too.

you can confirm:

click file>publish>tick 'permit debugging'.  retest.

the problematic line of code will be in the error message.  if it's   REDquestLine = this['REDqestText' + i].text; and the i's match in the else-branch with the first error message, you've confirmed it.

[dalvydasv27776233]

First unctions work perfect for me and i get in this case 5 Text fields with instance names REDquestText0 REDquestText1 and etc. With second function I want to get all 5 strings from textfields in one String. But it not works as I want. I can get for examle TextField|TextField|TextField|TextField|TextField| but not the text in theese textfields. It sound simple thing but its so dificult to get. With permit Debugging I get same error and it not works

[kglad]

1. is REDquestLine = this['REDqestText' + i].text; triggering the error?

2. what values of i execute in the if-branch *

3. what's the last value of i traced just before the error? **

*

for (var i = 0; i < REDquestionsLineArray.length; ++i) {

        if(REDquestionsLine==null){

            //nedaryk nieko

trace(i)

        }else{

            trace("----++++++++++-----");

            var REDqText:TextField = new TextField();

            REDqText.name = 'REDqestText' + i;

**

function save_REG_questions(e:MouseEvent):void{

    saveREDquestionsLine = "";

    for (var i = 0; i < REDquestionsLineArray.length; ++i) {

trace(i)

       REDquestLine = this['REDqestText' + i].text;

        saveREDquestionsLine = saveREDquestionsLine + REDquestLine + "|";

        trace(saveREDquestionsLine);

    }

}

But I cant get text from theese text fields

[dalvydasv27776233]

and yes this line trigering the error.:/

[kglad]

your trace results don't make sense if you put those trace statements in the correct locations.

if you want to hire me to fix your problem, let me know.  if you want free via the forums you should follow my suggestions.

[dalvydasv27776233]

Everything makes no sense beouse verything looks ok and should work, why not workng i dont know:(((

I did everythink like you said and i get same error.

All in one frame and why i get this error i dont know,

[kglad · Accepted solution]

use:

function save_REG_questions(e:MouseEvent):void{

    saveREDquestionsLine = "";   

    for (i = 0; i < REDquestionsLineArray.length; ++i) {

        trace(TextField(this.getChildByName("text" + i)).text);

        saveREDquestionsLine = saveREDquestionsLine + REDquestLine + "|";

        trace(saveREDquestionsLine);

    }

}

TypeError: Error #1009: Cannot access a property or method of a null object reference. Its something crazzy ... trace(stage.getChildByName("text" + ).name); im geting : text0 text1 text2 text3 text4 trace(TextField(this.getChildByName("text" + i)).text); im getting error TypeError: Error #1009: Cannot access a property or method of a null object reference so i use STAGE not THIS and it works!
