Textarea Control - Limit Characters And Lines Entered By Users?
Oct 27, 2009
I have a script that limit characters and lines entered by users in a textarea.. I want instead of throwing that alert message to jump to the next line and the user can continue writing, here is the script:
<script type="text/javascript">
var alert_title='Input Restriction';
function limitTextarea(el,maxLines,maxChar){
if(!el.x){
el.x=uniqueInt();
el.onblur=function(){clearInterval(window['int'+el.x])}
}window['int'+el.x]=setInterval(function(){
var lines=el.value.replace(/
/g,'').split(' .....
The HTML
<textarea onFocus="limitTextarea(this,5,40)" wrap="soft">
I have the following requirement for a textarea:Limit the number of lines to 8 Limit the number of characters to 20 per line Force a line beak when the user reaches he end of a line but break the line at the start of the last word (not half way through the word).Allow pasting into the field and auto-format the line/character countKeep he cursor where it should be (don't move it to the end of the field after any formatting)
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;
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.
This involves the use of an order form used to process a purchase via Paypal. The items are small rhinestone letters for names and such.
The form is very simple in that the purchaser enters into form field one: the letters they wish to purchase. Form field two (this is where I rely on common sense by the purchaser): enter the number of letters entered in form field one.
Based on the number of letters entered in form field two, my form processes the correct cost for the purchase.
As you have already figured out, I am beginning to see people enter their letter orders w/out entering the number of letters ordered.
All that said: a way to count the letters entered in form field one and auto-populate form field two with that number. Code:
I'm using the following code to display the latest threads from my vBulletin forum in my footer, however I'd like to limit the number of characters that are shown in the Thread title.
Can anyone show me what needs to be changed to say limit it to the first 20 or so characters?code...
I want an option which checks the maximum size of characters entered. Following is an HTMl code with javascript. this Javascript checks whether the field is empty or not. but i need one more option which checks and alerts if the characters entered in the username field r more than 15. As I am not so familiar with the javascript coding,
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.
Awhile back I posted a script that was working fine in IE but not in Firefox. This is again my dillema with another piece of code.It is supposed to limit the number of characters accepted by a textbox.Here's the JS:
<script type="text/javascript"> function textCounter(field,cntfield,maxlimit) { // if too long...trim it!
I'm creating web application in asp.net using vb.net. I have two textboxes txtbox1, txtbox2 respectively. In txtbox1, as and when I entered two characters, the cursor should automatically moved to txtbox2.
Is there any way of counting, on the onkeyup event of a textarea, the number of lines? I tried with a split, but the wrap doesn't seem to insert any char I could split on?
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 have a website with an admin area for my clients. The input text is then inserted in a page on their website - inside a <p> tag. What I'm trying to do is locate a script that would allow them to use such tags as <b>, <i>, <u>, but not others like <p>, <div>, etc. Does someone know of such a script?
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?
[vbs] function LimitText(fieldObj,maxChars) { var result = true; if (fieldObj.value.length > maxChars) { result = false; }
if (window.event) { window.event.returnValue = result; }

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.
