JavaScript to cut a long string between words

Hi all,

I'm trying to figure out how to write a JavaScript function that will trim some text to a specific length, but not in the middle of a word - it could only trim on whitespace. So, if I called it like trimText(strTheText, 500), then it wouldn't necessarily trim at 500 - it might trim at 497 if there is a word between 498 and 506. We can assume that it always trims smaller than the given length. Even if there is a space at 501, which is closer to 500, it should still trim back at 493 or whatever.

This is what I started with, when I found it trimming in the middle of a word:

function trimText(strTheText, intSize) {
if(strTheText.length <= intSize) {
return strTheText;
}
else {
return strTheText.substr(0,500) + '...';
}
}

Anyone have any ideas on this? Code would be best ... thanks!

Wow, 1 line!!

Shame I get an error.

TypeError: str.slice is not a function

Well, I ran through it, and using it the long way (without everything on 1 line) works.

Here's my final:

$("#myDiv .stuff").each(function(){
var theString = String($(this).text());
theString = theString.slice(0, 75);
theString = theString.substr(0, theString.lastIndexOf(" "));
$(this).text(theString + " ...");
});

Thanks!!
