disable enter

[Guest]

Hi i have a text area, which i need to stop users from using the enter key

ie

inside the text area the user can only use the spacebar and can NOT use the enter key to space out words

how can this be done?

why do you want to prevent the use of Return/Enter key in your textarea?
if it has to do with formatting of user's input for stroing/isplay, then
there are other things you should be doing instead of disabling keys...
otherwise, google for "javascript disable enter key" - you will have to
write a js function to treat Enter/Return as a space inside your textarea

ok the text area is a text area for sms text, if a user presses enter, the sms message gets cut off where the enter has been clicked.

ie if a user types

hello paul (enter)
what wrong

only the hello paul goes through

so i need to stop the user from using the enter key inside the text box

i see..
well, you can use Replace() function on the user's input string to
replace all Chr(10) and Chr(13) with " " (space) before sending the
sms... or use a regex:

#REReplace(form.textareaname, "(Chr(13)|Chr(10))", " ", "ALL")#

ok thanks

what is Chr(10) and Chr(13) ?

does that = enter?

if so how can i do the replace and then cfset a session.message

[Newsgroup_User]

they are equivalents of CR and LF (carriage return and line feed)
characters - which is what pressing Return key inserts into the textarea
(depending on the operating system, either one of them or both)

Ok so if i use
#REReplace(form.textareaname, "(Chr(13)|Chr(10))", " ", "ALL")#

how do i set the new version without returns as a session

[Newsgroup_User]

if i understand you correctly:

you have a form where a user can type some text to send as sms;
lat's say that textarea in the form is named "smstext";
in the form's action page (in the code that processes form submission)
you will <cfset texttosend = REReplace(form.smstext,
"(Chr(13)|Chr(10))", " ", "ALL")>
so now the sms text without line feeds or carriage returns is stored in
the "texttosend" variable.

if you need to store that in the session scope, just do <cfset
session.texttosend = REReplace(form.smstext, "(Chr(13)|Chr(10))", " ",
"ALL")> instead.

you can use whatever valid variable name you want instead of "texttosend".
don't forget to use your actual textarea's name instead of "smstext".

sorry, my fault. here's correct code:
<cfset texttosend = REReplace(form.message, "(#Chr(13)#|#Chr(10)#)", "
", "ALL")>

... i forgot the pound signes around Chr(xx)...
