Hi,

I'm running this function on a string, but sometimes that string doesn't have a " "... how can I test to see if it does or not before running the function.. so I don't get errors...

function trimFat(str)
{
    var temp = new Array();
    temp = str.split(" ");
    return (temp[0]);
}

Use the str.indexOf function, so it would be:

function trimFat(str)
{
    if(str.indexOf(" "))
    {
        var temp = new Array();
        temp = str.split(" ");
        return (temp[0]);
    }
}
