Help needed adding "sub space for underscore or %20" in script

[mana7]

Hello.

I am using a script that I received from someone after I posted a request at this site (thanks!), which finds a specific directory name and displays it on the webpage in a specified table. The script is working well, except for directories with two or more words. If the multiple word directory name is written with an _underscore_ in place of the blank space, then the underscore is displayed in the title. If the directory has a blank space, then the blank space is displayed as "%20" in the title.

For example:

1) A directory named "Blue_Bird" becomes a section title displayed as "Blue_Bird" ... but I would like the script to be told to substitutle a blank space for an underscore, so the title would read: "Blue Bird"

2) A directory named "Red Bird" becomes a section title displayed as "Red%20Bird" ... but I would like the script to be told to display a blank space for a blank space (or for a "%20", if it is picking this up from the code), so the title would read: "Red Bird"

Following is a copy of the existing script:

<script type="text/javascript">
function disp_current_directory(){
var ext='htm';
var dirs=window.location.href.split('/'),
cdir=dirs[dirs.length-2];
document.write('<a href="'+cdir.toLowerCase()+'.'+ext+'">'+cdir.toUpperCase()+'<\/a>');
}
disp_current_directory();
</script>

Thanks in advance for any help!

I believe str.replace should be able to work.

Thanks GM,

I'm a novice.
Would it be possible for you to insert str.replace into the exisiting script and resend?

Thanks!

I'm actually not sure how to use it, since JS isnt' really my area. I'd suggest googling it, or just being patient until someone else can tell you.

http://www.w3schools.com/jsref/jsref_replace.asp <<looks like good info.

So... something like:
mystring.str.replace('_',' ');

<script type="text/javascript">
function disp_current_directory(){
var ext='htm';
var dirs=window.location.href.split('/'),
cdir=dirs[dirs.length-2];
document.write('<a href="'+cdir.toLowerCase()+'.'+ext+'">'+unescape(cdir).toUpperCase().replace(/_/g,' ')+'<\/a>');
}
disp_current_directory();
</script>

You'd need to use the function twice, though, since you want spaces kept as well. (Or, &#37;20.)

Who, me? Which function? The way I wrote the function, it unescapes (which replaces all %## entities with their actual characters) before it replaces underscores with spaces.

One thing that puzzles me though, and I think I wrote the original code that this comes from is why .toLowerCase() for the link's href? I think it should be the verbatim cdir string because, if that contains upper case letters and they are changed to lower case letters, it will become a different and probably invalid href.

Oh, ok. I misread your script. I agree about the lowercase.
