JQuery :: Word Wrap A Textarea At X Number Of Characters?

Jul 14, 2010

I am currently seeking help on how to best approach finding a solution to this. Essentially I have a textarea which a user is supposed to be typing a text based email message(no HTML) The textarea has a column width of 80 However there is a recommended width of 53 characters per line. Obviously the user can just keep on typing away past the 53 character recommended width if they want, but I want to add either a form button or a link with an onClick thatanalyzes the contents of the textarea. It should insert a hard return when it reaches 53 characters, but if the 53rd character is in the middle of a word it should count back to the previous space and do the line wrap there.

Can anyone point me in the right direction? I assumed there has to a solution using jQuery, but I am at a loss. I did come across some javascript which works, but it doesn't take into account the fact that the 53rd character maybe in the middle of a word.

Wrap Lines After X Number Of Characters In A Textarea But NOT In The Middle Of A Word

Jul 14, 2010

I have a textarea with a specific width. I have wrap="off" set because I don't want to force my users to wrap if they don't want to. The reason for this is because this textarea is where the user is typing an email message. However I have a background image set on the textarea with a verticle line going down the textarea which indicates to the user the "Recommend Width"What I want to do is provide them with a link to click on which says something like "Wrap Lines" and when they click on it, the text within the textarea would wrap to the "Recommended Width" line in the background image. The maximum length of a line should be 53 characters when they click on "Wrap Lines" link.So I did some searching around and the code I came up with is:

function showLines(max, text) {
text = "" + text;
var temp = "";
var chcount = 0;

Document.write Output Won't Stay Inside Div / Get Values To Word-wrap When They Get To End Of Container?

Jun 21, 2010

I want to use document.write to output the values of an array. If the array is too long, it totally ignores the width of the container div. How do I get the values to word-wrap when they get to the end of the container?

I've searched on this forum, and also googled for the answer but can't find a solution. I'm still fairly new to Javascript.

Wrap Attribute Of The <textarea> Element

Apr 7, 2011

I just have a question regarding the wrap attribute of the <textarea> element. I am using Programmer's Notepad. I am doing an example using the split() method in JavaScript. On the <textarea> element, it has specified that I use the 'wrap' attribute, yet when I enter this code, my attribute highlights red (which usually means that you have made a spelling mistake with the element/attribute). Now, obviously I know I haven't spelt wrap wrong and it certainly tells me in this book that you can use this attribute, so is this attribute deprecated?

I searched about this problem over Internet and found the same result many times, I found this example on stackoverflow [URL] but this example didn't work in my project; I am making a toolbar with buttons that insert HTML tags around the selected text in a <textarea>, this exemple didn't work because when the user click on a button the selected text won't be selected anymore because <textarea> loses focus and selected text will be unselected, I am targeting Firefox and compatible browsers so you don't need to give me the IE code; jQuery codes are accepted;

Switch Textarea Wrap Realtime

Oct 24, 2005

I am trying to write a script that changes a textarea wrap realtime, basically like you can switch to and from "wordwrap" in Microsofts Notepad. Because of a bug (https://bugzilla.mozilla.org/show_bug.cgi?id=302710), FireFox does not listen to the textarea.wrap = 'soft' command. Because I want the script to be cross-browser compatible, someone suggested to remove and immediately add a node to the DOM, so I now have: Code:

Number To Word Translator

Aug 22, 2002

Don't know if there is one of these online, so I made me own. Simple function that outputs a number as words. First argument is the number, second argument is flag (default = false) that controls whether output is cardinal or ordinal - as in "one" or "first".

Goodness knows if I have the grammer correct, especially when the numbers get big. Enjoy!


1) Doesn't work with WebTV or below NS 4. Changing the large literal array into a common array should fix that, but I didn't bother.

2) Converts number into an integer before wording number. So, no "one point forty-five" stuff. This function is a good start for anyone who wants to do that though.

3) Always returns, "zero" for 0. Couldn't find cardinal equivalent to "zero"... zeroeth?

Num2Word, ouputs written number in human language format
Nbr: num, the number to be worded. This number is converted into an integer.
Crd: bol, flags whether output is cardinal or ordinal number. Cardinal is used when describing the order of items, like "first" or "second" place.
function Num2Word(num,fmt) {
//_ arguments
num = Math.round(num).toString(); // round value
if (num == 0) return 'zero' // if number given is 0, return and exit
//_ locals
// word numbers
var wnums = [['hundred','thousand','million','billion','trillion','zillion'],['one','first','ten','','th'],['two','second','twen',0,0],['three','third','thir',0,0],['four','fourth',0,0,0],['five','fifth','fif',0,0],['six','sixth',0,0,0],['seven','seventh',0,0,0],['eight','eighth','eigh',0,0],['nine','ninth',0,0,0],['ten',],['eleven',],['twelve','twelfth'],['thirteen',],['fourteen',],['fifteen',],['sixteen',],['seventeen',],['eighteen',],['nineteen',]];
// digits outside triplets
var dot = (num.length % 3) ? num.length % 3 : 3;
// number of triplets in number
var sets = Math.ceil(num.length/3);
// result string, word as number
var rslt = ''
//_ convert every three digits
for (var i = 0; i < sets; i++) { // for each set of triplets
// capture set of numbers up to three digits
var subt = num.substring((!i) ? 0 : dot + (i - 1) * 3,(!i) ? dot : dot + i * 3);
if (subt != 0) { // if value of set is not 0...
var hdec = (subt.length > 2) ? subt.charAt(0) : 0; // get hundreds digit
var ddec = subt.substring(Math.max(subt.length - 2,0),subt.length); // get double digits
var odec = subt.charAt(subt.length - 1); // get one's digit
// hundreds digit
if (hdec != 0) rslt += ' ' + wnums[hdec][0] + '-hundred ' + ((fmt && ddec == 0) ? 'th' : '');
// add double digit
if (ddec < 20 && 9 < ddec) { // if less than 20...
// add double digit word
rslt += ' ' + ((fmt) ? ((wnums[ddec][1]) ? wnums[ddec][1] : wnums[ddec][0] + 'th') : wnums[ddec][0]);
} else { // otherwise, add words for each digit...
// add "and" for last set without a tens digits
if ((0 < hdec || 1 < sets) && i + 1 == sets && 0 < ddec && ddec < 10) rslt += 'and '
// tens digit
if (19 < ddec) rslt += wnums[ddec.charAt(0)][(wnums[ddec.charAt(0)][2]) ? 2 : 0] + ((i + 1 == sets && odec == 0 && fmt) ? 'tieth' : 'ty') + ((0 < odec) ? '-' : ' ');
// one's digit
if (0 < odec) rslt += wnums[odec][(i + 1 == sets && fmt) ? 1 : 0];
// add place for set
if (i + 1 < sets) rslt += ' ' + wnums[0][sets - i - 1] + ' ' // if not last set, add place
} else if (i + 1 == sets && fmt) { // otherwise, if this set is zero, is the last set of the loop, and the format (fmt) is cardinal
rslt += 'th' // add cardinal "th"
//_ return result
return rslt

Test the result of various valies like so

for (var i = 0; i < 50; i++) {
var x = Math.round(Math.random() * 5000000);
document.write(x,' -> ' + Num2Word(x).bold(),'<BR>');

Use this function towards whatever means you deem necessary. Pease credit me, Bemi Faison, if you use this script.

My plan is to find the index of the cursor position on the textarea. then go left and right from that index. Stop on getting space on both side. Find both the indexes and select that range. But I am not able to do it. I am stuck in the first step.

Get The Last Two Characters Typed Into A Textarea?

Oct 17, 2010

I am writing an HTML builder. On thing that I think would be helpful is if the user types in


A javascript adds another " for the user, but puts the cursor inbetween the two "'s. In other words, the javascript should assist users in writing HTML/Javascript codes. This may also be applied to < & >.

I have found this script that can get your position in a textarea. I also thought this might be of help:

var textarea = document.getElementById('code');
var tmp = textarea.value;
textarea.value = textarea.value.substring(0, textarea.selectionStart) + '"' + tmp + textarea.value.substring(textarea.selectionEnd);

Although I have tried, I have not been able to piece the scripts together.
