Thread: How Do You Search An Array?

  1. #1

    Post

    I want to have a button that when clicked will search an array for a word that has been inputted to a text box by the user. Sort of like a spell checker.

    I have tried searching this site (tutorials and forums) and have had no luck.

    Someone suggested using a text file instead of an array but I have no idea on how to search a text file either.

    I'm not new to Flash and I know the basics of Actionscript but I'm finding it very difficult to figure out how to do this and would appreciate some help on the matter.

    Thanks.

    If your array is called textArray, you can use the following. The variable 'myWord' is set to the string you are looking for:


    Code:
    for (j=0, j<=textArray.length, j++){
      if (textArray[j] == myWord){
        someFunction();
        break;
      }
    }
    hope this helps you

    Hi,

    if your text box is called text, try
    Code:
    if(text.indexOf('word') >= 0)
    {	// word appears in text
    }
    if you have an array of words to look for,
    Code:
    wordlist = ['love', 'letter', 'virus']
    
    for(i = 0 ; i < wordlist.length ; i++)
    	if(text.indexOf(wordlist[i]) >= 0)
    	{	// ok, found one
    	}
    Dont expect flsh to be very efficient on that, so checking a long text may get you "running slow" alerts

    Thank you, it works great.

    I'm glad I don't have that to bother about now.

    The array is going to be quite big so that could pose a bit of a problem.

    I'll see how it goes.

    Thanks again.

    Hi,

    if both the array and the text get big, you should do a few words at a time in a frame loop - or if the words to check are fixed, you could use to a completely different approach where not a list of words is loaded into flash, but rather a table created from the list of words by a separate program

    concept of frame loop
    1st frame in loop:
    ctr = 0;
    end = wordlist.length;
    2nd frame
    Code:
    for( ; ; )
    {	if(text.indexOf(wordlist[ctr]) >= 0)
    		// found one
    	if(++ctr == end)
    	{	nextFrame();
    		break;
    	}
    	else if((ctr % 20) == 0)
    	{	prevFrame();
    		break;
    	}
    }

    I might try it with seven arrays.

    The game I'm making only allows you to make a words of 3 - 9 letters so I was going to make an array for each word length.

    Hopefully that should make it less resource hogging.
