RE: [flexcoders] string trim

[Matt Chotin]

Here's an alternative to Tracy's that I've used:

function trimString(str : String) : String
{
    var startIdx = 0;
    while(str.indexOf(' ',startIdx) == startIdx)
        ++startIdx;
    var endIdx = str.length-1;
    while(str.lastIndexOf(' ',endIdx) == endIdx)
        --endIdx;

    if (endIdx >= startIdx)
    {
        return str.slice(startIdx,endIdx+1);
    }
    else
    {
        return "";
    }
}
