[SOLVED] Help with slug function

[scarhand]

The regex does not seem to be working here.

 

function trim(str, chars) 
{
return ltrim(rtrim(str, chars), chars);
}

function ltrim(str, chars) 
{
chars = chars || "\\s";
return str.replace(new RegExp("^[" + chars + "]+", "g"), "");
}

function rtrim(str, chars) 
{
chars = chars || "\\s";
return str.replace(new RegExp("[" + chars + "]+$", "g"), "");
}

function putslug(str)
{
str = str.toLowerCase();
str = trim(str);
str = str.replace(/[^a-z0-9-]/, '-');
str = str.replace(/-+/, '-');
str = trim(str, '-');

document.getElementById('slug').value = str;
}

Problem at line 22 character 31: Unescaped '-'.

So I escaped the two "-"'s in the regex:

 

str = str.replace(/[^a-z0-9\-]/, '-');
str = str.replace(/\-+/, '-');

 

and its still not working properly. Did I do this correctly? You'll have to forgive me, I am so used to PHP that javascript seems fairly unfamiliar.
