Textarea line capture

Copy linkTweet thisAlerts:
Mar 22.2010

Let me start by saying that I am very new to javascript and programming in general so please be a specfic as you can with your answers. What I am trying to do is use javascript to grab each line (word wrapped at 95 characters) in a textarea and place it into an array so that I can pass the variables to the page that follows the form submission without splitting any words in half. So I guess this means breaking down the textarea into textarea1, textarea2, textarea3, etc. Is this even possible? Any help is greatly appreciated.

<textarea name="textarea" cols="95" rows="10"></textarea>

@mrhooMar 22.2010 — If you want to ignore all newlines and tabs and just break on spaces,

build the array by finding the last space in each 95 character chunk.



[CODE]function wordwrap(s, L){
// trim leading and trailing spaces and convert
// all whitespace sequences to single spaces:
s= s.replace(/(^s*|s*$)/g,'').replace(/s+/g,' ');
var a= [], ax;
while(s.length> L){
ax= s.substring(0, L).lastIndexOf(' ');
if(ax== -1) ax= L;
a[a.length]= s.substring(0, ax);
s= s.substring(ax);
}
if(s.length) a[a.length]= s;
return a;
}[/CODE]
//test

var s= document.getElementsByName('textarea')[0].value || '';

[B]alert(wordwrap(s,95).join('n'));[/B]

Success!
