Using var.replace("foo") when no break spaces are present.

Copy linkTweet thisAlerts:
Apr 28.2010

I may have the solution but advice still needed.

I have grabbed all the links in an array and tried bubble sorting them alphabetically. The first two things I noticed was the “n” which I can eliminate but I use Firebug as my debugger and it reports whitespace as whitespace. I do use a lot of   ‘s in the HTML so it may be these that cause the results to show “undefined”. I tried removing “undefined” and got a null instead. I tried removing the null and got undefined.

As I am looking at the “.text” property and Firebug probably shows   as whitespace , maybe I should look for   and possibly use “.innerHTML” instead. All I need is to remove leading, trailing & multiple spaces.

What do the experts think? I am going home to try, but this is at the end of a very long road.

TIA

@KorApr 28.2010 — You may try Regular Expression to match and/or replace spaces:

@MrRedauthorApr 28.2010 — Sorry - I show have said I use RegExp's eg:
<i>
</i>fred.replace(/n/g,/ /)
//and then
fred.replace(/ /,/ /)
//as many times as is necessary.

what I may try before migrating to innerHTML is

fred.replace(/&amp;nbsp;/,/ /)

or same for the innerHTML instead.

I did (stupidly) try to remove "" & "n" as it was literally as displayed before the penny dropped.

@KorApr 28.2010 — The single space RegExp meta character is [b]s[/b]. [b]n[/b] has no special meaning.

@MrRedauthorApr 29.2010 — After trying all manner of things I found IE & FF can cope with

.charCodeAt(forloopnum) and re-constructing the variable from before and after the offending character - 160 for &nbsp; ( can't use bracket here in the presence of colons!!!) :eek:

Trying to do this with character 13 made it all fall apart - it is the delimiter in arrays!!! but that was solved anyway with

.replace(/n/,/ /)

I did not have much joy with s or w.

Thanks for the advice.

Success!
