I have a textarea which is restricted to input only numbers. I want to remove carriage return char after user presses enter key. Here's my code:
// Change tempo
function changeTempo(event:KeyboardEvent):void {
if (event.charCode == 13) {
// Some code here
}
// Remove enter char
removeCarriageReturnsAndNewLines(tempo_txt.text);
}
function removeCarriageReturnsAndNewLines($myString:String):String {
var newString:String;
var findCarriageReturnRegExp:RegExp = new RegExp("\r", "gi");
newString = $myString.replace(findCarriageReturnRegExp, "");
var findNewLineRegExp:RegExp = new RegExp("\n", "gi");
newString = newString.replace(findNewLineRegExp, "");
return newString;
}
I would say the easiest way is to listen to text input, something like this:
var t:TextArea = this.ta; //ta is on the timeline
t.restrict = "0-9"; //restricts the input only to numbers
t.addEventListener(TextEvent.TEXT_INPUT, onTextInput, true); //use capture phase to be able to prevent the default behavior (text input)
function onTextInput(e:TextEvent):void {
if(e.text.indexOf("\n") > -1) {
e.preventDefault(); //prevent the default behavior of the field
}
}
I cannot test this right now but I guess it should work without problems.
My User has the following selection in his Gdoc.
Now from the sidebar he wants to to replace the selection he made on the document. The GAS question is if it is possible to do that at once, something like:
var selection = DocumentApp.getActiveDocument().getSelection()
selection.replace("newtext")
Or do I have to loop through selection.getRangeElements() in order to delete them (or replace them) and than in someway place the new text in that position?
Not, that's not possible (well, if it is, it's not documented).
You have to loop through the selected elements, mainly because the selection may take part of paragraphs, forcing you to manage that. i.e. deleting just the selected part. And for completed selected elements, you can just remove them entirely (like images).
Here's an implementation on how to do this (part of the Kaylan's Translate script modified by me to properly replace images and partially selected paragraphs.
function replaceSelection(newText) {
var selection = DocumentApp.getActiveDocument().getSelection();
if (selection) {
var elements = selection.getRangeElements();
var replace = true;
for (var i = 0; i < elements.length; i++) {
if (elements[i].isPartial()) {
var element = elements[i].getElement().asText();
var startIndex = elements[i].getStartOffset();
var endIndex = elements[i].getEndOffsetInclusive();
var text = element.getText().substring(startIndex, endIndex + 1);
element.deleteText(startIndex, endIndex);
if( replace ) {
element.insertText(startIndex, newText);
replace = false;
}
} else {
var element = elements[i].getElement();
if( replace && element.editAsText ) {
element.clear().asText().setText(newText);
replace = false;
} else {
if( replace && i === elements.length -1 ) {
var parent = element.getParent();
parent[parent.insertText ? 'insertText' : 'insertParagraph'](parent.getChildIndex(element), newText);
replace = false; //not really necessary since it's the last one
}
element.removeFromParent();
}
}
}
} else
throw "Hey, select something so I can replace!";
}
I'm tying to pass the contents of
B1L_bnt.text
to
buddy_txt.text
Can anyone tell me what am doing Wong here?
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = "bobby";
Object(root).gotoAndPlay(15);
}
Try this:
function clickHandler(event:MouseEvent):void
{
/*container_mcM.removeEventListener(MouseEvent.CLICK,clickHandler);*/
var clickedObject:DisplayObject = event.target as DisplayObject;
var bobby = Object(root).littlepicker.B1L_bnt.text;
if (clickedObject.name == 'frd_bnt1')
{
Object(root).BFFwho.buddy_txt.text = bobby;
Object(root).gotoAndPlay(15);
}
The issue was that you were declaring a variable named bobby. When you were trying to set the text of buddy_txtyou were setting it to a literal String 'bobby' instead of the value of the variable.
Greetings,
This is my first post and I hope someone out there can help. I am an educator and I designed a quiz using Actionscript 3 (Adobe Flash) that is to determine all the different ways a family can have three children.
I have two buttons that enter either the letter B (for boy) or G (for girl) into an input text field named text_entry. I then have a submit button named enter_btn that checks to see if the entry into the input text is correct. If the input is correct, the timeline moves to the next problem (frame labeled checkmark); if it is incorrect the timeline moves to the end of the quiz (frame 62).
The following code works well for any particular correct single entry (ie: BGB). I need to write code in which all eight correct variations must be entered, but they can be entered in any order (permutation):
ie:
BBB,BBG,BGB,BGG,GBB,GBG,GGB,GGG; or
BGB,GGG,BBG,BBB,GGB,BGB,GGB,BGG; or
GGB,GGG,BBG,BBB,GGB,BGB,BGB,BGG; etc...
there are over 40,000 ways to enter these eight ways of having three children. Help!
baby_B.addEventListener(MouseEvent.CLICK, letterB);
function letterB(event:MouseEvent)
{
text_entry.appendText("B");
}
baby_G.addEventListener(MouseEvent.CLICK, letterG);
function letterG(event:MouseEvent)
{
text_entry.appendText("G");
}
enter_btn.addEventListener(MouseEvent.CLICK, check);
function check(event:MouseEvent):void {
var solution_S:Array=["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG "];
if(solution_S.indexOf(text_entry.text)>=0)
{
gotoAndStop("checkmark");
}
else
{
gotoAndPlay(62);
}
}
If you know the correct code, please write it out for me. Thanks!
You will just need to keep a little bit of state to know what the user has entered so far. One possible way of doing that is to have a custom object/dictionary that you initialize outside all your functions, so that it is preserved during the transitions between frames/runs of the functions:
var solutionEntered:Object = {"BBB":false, "BBG":false, /*fill in rest */ };
Then in your function check you can perform an additional check, something like:
function check(event:MouseEvent):void {
var solution_S:Array=["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG "];
if(solution_S.indexOf(text_entry.text)>=0) {
// We know the user entered a valid solution, let's check if
// then entered it before
if(solutionEntered[text_entry.text]) {
// yes they entered it before, do whatever you need to do
} else {
// no they haven't entered it, set the status as entered
solutionEntered[text_entry.text] = true;
}
// continue rest of your function
}
// continue the rest of your function
}
Note that this is not necessarily an optimal solution, but it keeps with the code style you already have.
Try this:
import flash.text.TextField;
import flash.events.MouseEvent;
import flash.display.Sprite;
var correctAnswers : Array = [ "BBB", "BBG", "BGB", "GBB", "BGG", "GGB", "GBG", "GGG" ];
var answersSoFar : Array;
var textField : TextField; //on stage
var submitButton : Sprite; //on stage
var correctAnswerCount : int;
//for testing
textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG,GGG";
//textField.text = "BGB,BBB,GGG,BBG,GBB,BGG,GGB,GBG,";
//textField.text = "BBB,BBG, BGB,GBB,BGG, GGB, GBG, GGG";
//textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG";
//textField.text = "BBB,BBG,BGB,GBB,BGG,GGB,GBG,GGG,BBG";
submitButton.addEventListener( MouseEvent.CLICK, onSubmit );
function onSubmit( event : MouseEvent ) : void
{
var answers : Array = getAnswersArray( textField.text );
answersSoFar = [];
correctAnswerCount = 0;
for each ( var answer : String in answers )
if ( answerIsCorrect( answer ) ) correctAnswerCount++;
if ( correctAnswerCount == correctAnswers.length ) trace( "correct" );
else trace( "incorrect" );
}
function getAnswersArray( string : String ) : Array
{
string = removeInvalidCharacters( string );
return string.split( "," );
}
function removeInvalidCharacters( string : String ) : String
{
var result : String = "";
for ( var i : int, len = string.length; i < len; i++ )
if ( string.charAt( i ) == "B" || string.charAt( i ) == "G" || string.charAt( i ) == "," )
result += string.charAt( i );
return result;
}
function answerIsCorrect( answer : String ) : Boolean
{
if ( answerIsADuplicate( answer ) ) return false;
else answersSoFar.push( answer );
if ( answerIsInListOfCorrectAnswers( answer ) ) return true;
return false;
}
function answerIsInListOfCorrectAnswers( answer : String ) : Boolean
{
if ( correctAnswers.indexOf( answer ) == -1 ) return false;
return true;
}
function answerIsADuplicate( answer : String ) : Boolean
{
if ( answersSoFar.indexOf( answer ) == -1 ) return false;
return true;
}
note that in the original code you pasted, you have an extra space in the last element of your correct answer list - "GGG " should be "GGG"
this works
baby_B.addEventListener(MouseEvent.CLICK, letterB);
function letterB(event:MouseEvent) {
text_entry.appendText("B");
}
baby_G.addEventListener(MouseEvent.CLICK, letterG);
function letterG(event:MouseEvent) {
text_entry.appendText("G");
}
var valid:Array = ["BBB","BBG","BGB","BGG","GBB","GBG","GGB","GGG"];
enter_btn.addEventListener(MouseEvent.CLICK, check);
function check(event:MouseEvent):void {
var parts:Array = text_entry.text.split(/,\s*/g); // split the text into component parts
var dup:Array = valid.slice(); // copy the correct list
while(parts.length){ // run through each answer component
var part:String = parts.pop(); // grab the last one
part = part.replace(/(^\s+|\s+$)/g, ''); // strip leading/trailing white space
var pos:int = dup.indexOf(part); // is it in the list of correct answers?
if(pos != -1){ // if it is...
dup.splice(pos, 1); // then remove that answer from the list
}
}
if(dup.length == 0) { // if it's 0, they got all the correct answers
gotoAndStop("checkmark");
} else { // otherwise, they didn't get one or more correct answers
gotoAndPlay(62);
}
}

how to compare..if equal just alert nochange if not alert chaged
If you just want to know if they are different from each other, meaning by length, order or individual items, you can do the following, which first checks to see if the lengths are different, then checks to see if the individual elements are different. This isn't terribly reusable, it's left as an exercise for the reader to split this apart into cleaner chunks :)
public function foo(coll1:ArrayCollection, coll2:ArrayCollection):void {
if (coll1.length == coll2.length) {
for (var i:int = 0; i < coll1.length; i++) {
if (coll1[i].first != coll2[i].first || coll1[i].last != coll2[i].last) {
Alert.show("Different");
return;
}
}
}
Alert.show("Same");
}
/* elements need to implement valueOf
public function valueOf():Object{}
*/
public static function equalsByValueOf(
first:ArrayCollection,
seconde:ArrayCollection):Boolean{
if((first==null) != (seconde==null) ){
return false;
}else if(!first && !seconde){
return false;
}
if(first.length!=seconde.length){
return false;
}
var commonLength:int = first.length;
var dictionary:Dictionary = new Dictionary();
for(var i:int=0;i<commonLength;i++){
var item1:Object = first.getItemAt(i);
var item2:Object = seconde.getItemAt(i);
dictionary[item1.valueOf()]=i;
dictionary[item2.valueOf()]=i;
}
var count:int = 0;
for (var key:Object in dictionary)
{
count++;
}
return count==commonLength;
}
/* valueOf sample
* something like javaObject.hashCode()
* use non changing fields(recommended)
*/
public function valueOf():Object{
return "_"+nonChangeField1+"_"+nonChangeField2+"...";
}
I was going to say this.
if(collectionArray === collectionArray1)
But that wont work (not triple = signs). As === is used to see classes.
I would write a function called check if object exists in array.
Create an array to hold elements that are not found. eg notFound
in Collection1 go through all the element and see if they exist in Collection2, if an element does not exist, add it to the notFound array. Use the function your created in step1
Now check Collection2, if an element is not found add it to the notFound array.
There is no 5.
Dude, use the mx.utils.ObjectUtil... the creators of actionscript have already thought about this.
ObjectUtil.compare(collection1, collection2) == 0;
