RegExp Question

[Don L-2]

I'm trying to break a large chunk of text, so, a user can click on MORE to to read the rest of it.
Using  the following technique has some success, however, it does not seem to be good enough.

-- cut off point, 500 characters
<cfset brkR = MID(myTxt,500,5)>
<cfset brk = Find(" ", brkR)>

<cfoutput>
#Left(myTxt,500+brk)#
then, upon clicking the MORE link, it display the rest as follows:
-- the main body of the txt
#Mid(myTxt,501+brk,Len(myTxt))#

</cfoutput>

Attempt to use
<cfset brk = REFind("[\s]", brkR)>
does not help or I didn't do it right.

It sort of works, but an issue is, it now shows &, nbsp; etc. special characters in the "breaking" area.  Question, what is a better way to do this?  If we stick with this method, how to use RegExp to remove the special characters in the output.

Thanks.

There are a number of UDFs on cflib that will handle this...

http://cflib.org/udf/FullLeft

... and probably a few others.  Browse the string library at

Great.  Thanks Charlie.  One thing, I don't get it about RegExp in this case per the second link, why two brackets as [[:space:]] instead of one as [:space:] ?

It's the posix expression [:space:] inside of a character class (surrounded
by square brackets)

so... [[:space:]]

I have done this before. The old way is to refresh the page. The new way is to toggle the rest of the content into view using Javascript.

Include JQuery

<div id="snip">
#left(var,500)#
</div>
<div id="btnA" onclick="$('#moreDiv').slideDown();$("#snip").hide()$(this).hide();$('#btnB').show()">MORE</div>
<div style="display:none" id="moreDiv">
#var#
</div>
<div style="display:none"  id="btnB" onclick="$('#moreDiv').show();$("#snip").show();$('#btnA').show();$(this).hide()">LESS</div>

Untested. You can put it into a function and pass in your div parameters, etc. Faster than reloading the page.

I'm having issues with Firefox filling in my UserID and Password fields on a
log-in form (present on every page). I want the fields be clear empty, so
the question is:

        How do I override Firefox and clear the form fields?

Here's what I've tried so far:

        1. Changed field names (no effect).
        2. CFINPUT Value="", no effect. CFINPUT Value=" " works, but in the
password field it show the space.
        3. Added a clear_form JS function and OnLoad of the page I clear the
fields. That works OnLoad, but if you hit the
                back button in the browser the OnLoad script does not run
and the fields are filled in again..

Any ideas?

Thanks,
Robert

Couple of options you can try:

1) add autocomplete="off" to the input
2) on page load do a document.forms['formname'].reset()
3) generate a UUID and append it to the field name (pass as a hidden input
to retrieve values on the action page).  this should ensure unique form
field names which should prevent auto-population.

I guess you then use one of the techniques mentioned elsewhere.... but
why do you, as the programmer, get to override my, as the user, preferences.

If I tell my Firefox to remember a password, I suspect I will be peeved
by a site that prevents me from using my desired feature.

But your millage may vary.

One reason could be Corporate policy.

I know one company for sure that will not be named that has a policy
that states that user id and password fields will be blank.

Even though they lock down the browser not to auto populate, some people
could still get past it.  Then for some reason, the powers that be
always go for the programmers.

Just one possibility.

It's a security issue. The users of site a very wealthy (and not necessarily
tech savvy) home-owners, generally with several homes. When they log-in to
this site they get access to the security systems in their home(s). They can
turn alarms on and off, unlock gates and door, turn lights on and off, heat
up their pool and sauna, etc.

Does that make sense?

And I presumed that this, or something very similar, was the driving
force behind the original question.  And, unfortunately, the main
problem with your scenario is the powers that be going for the
programmers - who only have an illusion of control, rather then the
employees who are breaking the policy.

Fine, just realize that it is only an *illusion* of security.  
/Anything/ you do on the server can be overridden by the client.  And
the sort of users who you really want to protect from, are the sort of
users who are going to know how to circumvent anything you can send form
the server.

I've always had an idea of randomizing a form element's name and passing
that random name to the following page to force the browser to not
autocomplete the information (it can't pre-populate if it's never seen the
form name before).

I've never actually worked out how to do this mainly because I've never had
to but I don't think it's very hard. Perhaps randomize the username field
and then have a hidden field named "username" and have the value as the
"real" username element's random name so you have access to it.

Just an idea.

Also, javascript can probably clear the fields if you just want them to be
blank, of course javascript can be turned off, but it's an alternative. Not
sure if you mean the form is autocompleting or just pre-populating.
