Confusing If Statement
I'm trying to create an if statement that will limit the amount of characters that are displayed from the document.write command. This is what i'm trying to get to happen. I need it so that if the text is over 500 characters long, the last 14 characters will be replaced with "...(hyperlink)"

Code:
max_length = 500;
extra_text = "...(hyperlink)";
function trunc_text(str) {
if( str.length > max_length) {
str = str.substring(0, (max_length - extra_text.length)) + extra_text;
}
return str;
}
document.write(trunc_text("here are some words"));
