I have a varchar data field called notes that is displayed in javascript like:

 var text = "<div style=\"white-space:nowrap;\"><div align=\"left\" class=\"smalltext\"><strong>"+name +"</strong><BR>"+address +"<br>Phone: "+phone +em +web +"<BR><EM>"+notes +"</EM></div></div>";

Open in new window


How do I alter the +notes + to insert a <BR> after 10 words or if words are not possible, then 25 characters.

Attached code will split it up into 25 character blocks.
<SCRIPT language="JavaScript">

name = 'John Doe';

address = '100 Nowheresville';

phone = '800 555-1212';

em = 'em';

web = 'http://www.fofdsjklfasjflkasjfl.com/';

notes = 'This is a list of information that should be displayed as notes on the screen for the given user';



function split_text(text, char_count)

{

  new_text = '';



  while (text.length > 0)

  {

    if (new_text.length > 0) new_text += '<br>';

    new_text += text.substr(0, char_count);

    text = text.substr(char_count);

  }



  return new_text;

}



notes = split_text(notes, 25);

var text = '<div style="white-space:nowrap;"><div align="left" class="smalltext"><strong>'+ name +'</strong><BR>'+address +'<br>Phone: '+phone +em +web +'<BR><EM>'+notes +'</EM></div></div>';



document.write(text);

</SCRIPT>

You can use chr(13) and chr(10) from your server side script to add <br> .
In coldfusion it is

Text...#chr(13)##chr(10)#... text which actually displays like

Text.....
...text

Just print these two chars wherever you want line breaks

Split by 10 words..
var newnotes = note.split(" ");

var newstr = "";

for (i=0; i<newnotes.length; i++)

{

   if(y%10==0)  

      	newstr = words[i] + "<br>"
