Question

Displaying Arrays in text boxes - URGENT!!

Hello i am wanting to display the full content of an array in a text field. However this displays a comma between each array value which i dont not want.

How do i get rid of this?

The follow is the code i am using:

for (i=0; i<gNumOfQuestions; i++) {
if (gCorrectAnswers == gUserAnswers) {
gScore += 1;
userResult = (i+1)+" ("+gUserAnswers +") "+"= right\n";
textOutput.push(userResult);
if (i>1) {
userResult;
}
} else {
userResult = (i+1)+" ("+gUserAnswers+") "+"= wrong\n";
textOutput.push(userResult);
}
}
results_mc.results_txt.text = textOutput.join();

please note that my text box is held within a movie clip and the "i" has 1 added to it to giv the correct question number because of the way arrays are indexed from 0 upwards.

The following is the output i get:

1 (d) = wrong
,2 (d) = right
,3 (d) = right
,4 (d) = wrong
,5 (d) = wrong
,6 (d) = wrong
,7 (d) = wrong
,8 (d) = wrong
,9 (d) = wrong
,10 (d) = wrong
,11 (d) = wrong
,12 (d) = wrong
,13 (d) = right
,14 (d) = right
,15 (d) = right
,16 (d) = right
,17 (d) = wrong
,18 (d) = wrong
,19 (d) = wrong
,20 (d) = wrong
,21 (d) = wrong
,22 (d) = wrong
,23 (d) = wrong
,24 (d) = wrong
,25 (d) = wrong
,26 (b) = wrong
,27(d) = wrong
,28(b) = wrong

it is the commas at the start of each line i want to lose.

i was thinkin about using the substr function but not sure how i could use this as i dont know how to use it to delete the first char from a line.

any help would be greatly appreciated.

thanks

lee

The default delimiter for the join() method is the comma ",". To use a different one just specify it in the method call.

The change to the following line should give you what you need:

results_mc.results_txt.text = textOutput.join();

change it to:

results_mc.results_txt.text = textOutput.join(" ");

This will use a space " " as the demliniter instead of the comma. If you don't even want the space then use an empty string, like this:

results_mc.results_txt.text = textOutput.join("");

... i also ran into this problem and ended up creating a new var and appended the new array value to the end of it. I did this right after I added the new value to the end of my array. Not very cool, but it worked. And when I added the value to my var, I added "+" "" (2 spaces to the end of the last value) and my formatting was more controlled. Would love to find a better way to do this....

var myReturningString:String = new String("");// Creates an empty string
for (i = 0; i < gNumOfQuestions; i++) {
if (gCorrectAnswers == gUserAnswers) {
gScore += 1;
userResult = (i + 1) + " (" + gUserAnswers + ") " + "= right\n";
textOutput.push (userResult);
if (i > 1) {
userResult;
}
} else {
userResult = (i + 1) + " (" + gUserAnswers + ") " + "= wrong\n";
textOutput.push (userResult);
}
myReturningString += textOutput ;// on each time around will add the contents of the "i" array onto the end of the string
}
results_mc.results_txt.text = myReturningString;

Quick fix not tested it but should work.
