javascript problem: undefined variable

Shad · 06-27-2005, 11:05 AM

hey guys,

ive recently been playing around with javascript, and have had no problems, until now. it is quite a wierd problem. for example, when i define a variable:

Code:

var quoteuser_24=new Array()
quoteuser_24[0]='[something]example .......[/something]'

this would have no problem, however if i do this:

Code:

var quoteuser_24=new Array()
quoteuser_24[0]='[example]&lt;?
?&gt;
[/quote]'

this would have the error "undefined". im thinking it is the linebreak in the variable. Is there any solution to this so that i may use linebreaks in variables? My objective as you may have noticed is to insert the variable into a value onClick.

Help apreciated!

It is the newline that you are doing that is causing the problem. Why do you need a newline anyway? You can re-write the code like this:

Code:

quoteuser_24[0]='[example]&lt;?\n?&gt;\n[/quote]'

the "\n" will give you a new line in the string.

right, i wasn't sure that when inserting text into a value, \n would insert as a new line.

thanks

but theres the problem that i am getting the variable from MySQL in PHP.
and when there are line breaks in the database, how would you convert them into "\n"
i tried using $subject = str_replace("\n","<br>",$subject); however, the linebreaks still apear on the variable. not really sure what to do.

oh. i sorted the problem out, silly mistake =\

thanks for the help!
