Is there a way I can quickly remove a bloodshot?

Can anyone suggest a way to remove extra whitespaces from a string that exists in a Flash variable?

  • Can anyone suggest a way to remove extra whitespaces from a string that exists in a Flash variable? [more inside] I'm messing around with a Flash animation that started out as a http://www.jamesburnsdesign.com/tests/gibberish.html%20 It generates a nonsensical phrase from sentence fragments, but the result may have multiple whitespaces in it, and I need to remove them (unlike the JavaScript version, which automatically discards multiple whitespaces...). I think maybe the condenseWhite method may do this, but I can't figure out a simple way to implement it. Has anyone done this before?

  • Answer:

    This will do it for ya: String.split(" ").join(""); Replacing String with whatever your variable is called.

Won't String.split(" ").join(""); remove ALL spaces from a string? If you just want multiple spaces converted to single spaces try this: s = "       This is a test     of the program.    "; // String.prototype.removeExtraSpaces = function() { tmp = this; while (tmp.indexOf("    ") != -1) { found = tmp.indexOf("    "); tmp = tmp.substr(0, found)+tmp.substr(found+1); } // deal with a possible stray at the start of the string if (tmp.substr(0, 1) == " ") { tmp = tmp.substr(1); } // deal with a possible stray at the end of the string if (tmp.substr(tmp.length-1, tmp.length) == " ") { tmp = tmp.substr(0, tmp.length-1); } return tmp; }; trace("["+s.removeExtraSpaces()+"]");

// only tested as javascript - don't have flash on this machine - methods exist in both while (aString.indexOf("  ") != -1) {     var anArray = aString.split("  ")     aString = anArray.join(" ") }

move (replaces(" ",sTmpString," ")) to sTmpString oh... Wait... You said Flash, not the http://www.visualdataflex.com/, that I've managed to destroy my C.V. with.

Thanks, all. This seems to work with my variable called "outPut"(adapted from TimeFactor's version): function fixIt(){ anArray =outPut.split(" "); return(anArray.join(" ")); } (this is previewing OK, I may need to fix after actually posting...)

TimeFactor: Your method works great, unless there is space at the beginning of the string.

gwint

jpburns: If you know you'll never have more than two spaces in a row your version is preferable. Otherwise, you'll need the while loop. gwint: yup. or at the end.

TimeFactor

Yep... but for some reason the "while" method made Flash Player beachball, and then inform me that something in my code was taking a lot of time... ... since I'm making the pieces that get connected together, it's pretty easy to be assured that I won't have more than two spaces together. Thanks, again. It really helps to see an example like that.

I've never used it, but http://www.jurjans.lv/flash/RegExp.html wrote a reg exp. class for flash. It might be worth looking into.
