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:

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

[Code].....

Maximum Limit Of Lines On A Page?

May 9, 2011

I have been using Javascript to write a web application for my company to use as a manufacturing control system. It is all working very well, but I have come across a basic problem that many of you may know the answer to.

I start my web page by referencing jquery and a couple of plugins. Then I add my own Javascript functions. Following that I add all the PHP code and functions, followed by the HTML. The problem I have noticed is that if I add another Java script function, something stops working. take the function out, delete not comment out. and all is well again. After pulling my hair out for a while, I realised that there seems to be a limit to the amount on lines of Javascript I can put into the page. The solution is simple, just gather all my Javascript code and put it in another file with a .js extension and add it as a reference in the top of the file after jquery. I can then add as many line of code as I like without a problem.

how the lines of Javascript are limited?

JQuery :: Validation - Limit Characters To Be Input?

Feb 15, 2011

[URL]

Example for FirstName data input: Characters a-z,A-Z, hyphen, space are permitted. 0-1, !@#$%^&*()- etc are not permitted.

The plugin looks great but I am not able to figure-out how to limit which characters an end-user is allowed to input. Not just which characters are permitted but also which characters are not permitted.

Limit Char Over Two Textarea Boxes?

Sep 8, 2005

I have a form where users can enter text in one or two textareas. If they only enter text in of of the textareas I can limit the max char to 300 using this:

<script type="text/javascript">
var maxL=300;//nr of max permited characters
function limit(obj){
var nr= document.getElementById('nrc')
var v = new String();
s = obj.value.split('');
for(i=0;i<maxL;i++){v += s[i]}
if(s.length>=maxL){
obj.value=v;
nr.firstChild.data = maxL-v.length;
}
else{nr.firstChild.data = maxL-s.length;}
}
onload=function(){
document.getElementById('nrc').firstChild.data=maxL;
}
</script>

Is there a way that I can limit the total char between the two textareas i.e. If a user enters 180 in the first one they can only enter 120 in the second one.

I need to limit the chars typed in a textarea to 160 (size of an SMS ) It works fine - as long as no one is copy-pasting text to it. Then my lil JS fails *boohoo*. So, could anyone help me out? Should I nail this to some other event than OnKeyPress or what?

{
var result = true;
if (fieldObj.value.length > maxChars)
{
result = false;
}

if (window.event)
{
window.event.returnValue = result;
}

return result;
}

Usage:
<textarea name="myTextArea" OnKeyPress="LimitText(this,160)">

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:

Code:
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.

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.

Dynamically Resizing TextArea - Jerky And "bounce" When Adding Or Removing Lines

May 23, 2010

This is a two-fold question:

1. first I have a link for something that works but I want to work better:

[url]

The dynamically resizing textarea boxes are in light orange. They work, but they are rather jerky and you see some "bounce" when adding or removing lines -unlike Face Book which doesn't do this. Can anyone propose a better coding system that is smoother AND less processor intensive?

2. If you really do UNDERSTAND javascript at the programmatic level I'd be interested in having you work regularly for me, but I think I might need to post that in another forum. I'm a PHP programmer, and because I don't understand the JS Kernel and how it thinks, I'm always chasing my tail on it.
