Hi folks this one is proving to be a stumper for me. I have a single text area where people can enter text.

I want to output the textarea as a unordered bullet list with a new bullet point created every time the user hits the enter key in the text area.

so if they typed

product one [enter]
Product two [enter]
product three [enter]

there would be a list with there points.

Not quite sure how to do this. I tried some code using the paragraph formate function but could not get it to work.

Any help would be greatly appreciated

Hi jimmy I tried your code and it does not seem to work

here is my code did I make a mistake?

form page

<html>
<body>

<form name="form1" method="post" action="formAction.cfm">
  <textarea name="textarea" cols="25" rows="5"></textarea>
  <br>
  <input type="submit" name="Submit" value="Submit">
</form>


</body>
</html>

action page

<html>
<body>

<ul>
 
<cfoutput>
#ReReplaceNoCase("#form.textArea#","#chr(10)##chr(13)#","<li>","ALL")#
</cfoutput>
 
 
</ul>


</body>
</html>

Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

Hi jimmy it's getting closer

the only problem is there is no bullet point in frount of the first entry and there is also an extra bullet point at the end.

I am fairly new to CF I tried this but it threw a big fat error

#ReReplaceNoCase("<li>","#form.textArea#","#chr(13)#","ALL","</li>")#

Thought it might help to put the <li> tag first and add an end </li> tag

Thanks

actually what is happening is that this code converts all <enter>'s to <li>'s . so wherever u put a <enter>, it is converted to <li> . that is what ur question was.right?

Ya I guess it works if i manualy ad the first <li> tag before the code like this

<li>#ReReplaceNoCase("#form.textArea#","#chr(13)#","<li>","ALL")#

is it ok to not include a </li> closing tag after a list item. I see it doesn't throw an error in explorer but I wounder about other browsers?
