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!
[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 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)

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.
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">
How do I ensure a number has no more than 4 digits and 2 decimal places (adds .0 or .00 as necessary) onblur using reg expressions?
View 8 Replies View RelatedI wrote a short javascript code to try to solve a math puzzle. It involves iterating 50,000 times through a for loop. Nested in each of those iterations is another for loop with 50,000 iterations of its own. I think that's 2.5 billion altogether. Each times it compares two numbers that are being incremented.
I'm doing this in JS because I can't any of the Java I learned a few years ago...
I tested the code with much smaller numbers and it worked. With the big numbers my browsers are not responding, not surprisingly (I'm using the latest firefox on the latest mac os).
Will the code finish running tonight? Next week? In 10 years?
Have a dynamic table in JS that adds rows. Want a max of 8 rows. How can that be done?

I have a form with checkboxes. I have the results being stored as an array, that gets sent to a mysql database.
how can i limit the number of checkboxes selected? I am looking for a max of 15 selections.
i've been able to set the max when the checkboxes are not stored as an array, but for simplicity storing as an array is the way i need to go.
There will be a number of list boxes and other controls, with pop-up windows
to edit certain properties. It's the kind of thing I would normally have
done in VB but I want it to be browser-based. I've only used javascript for
trivial things before so this would be my first serious javascript
development. I would like it to run on all reasonably recent browsers.
The form starts with all the initial values being received from the server
(presumably just by pre-initialised data structures). The user tinkers with
it and when he is happy he presses 'submit' and the whole lot is submitted
to the server (presumably as a form post). This would be a few kb of data,
possibly 100 individual values but obviously in various data structures. I
guess there would be a few hundred lines of javascript code to manipulate
it.
My question is, is there likely to be a problem with manipulating and
sending this amount of data in Javascript. Sorry if this is a dumb question,
but like I said, I only used javascript for tiny programs before, so I'm a
bit unsure about its capabilities.
How would I add an if statement to limit the number input by the user to less than 20?
View 4 Replies View RelatedI have a function below where every time a question is submitted, it will add a new row in the table with a textbox which allows numbers entry only. My question is that I don't know how to code these features in this function:
I want the text box to be between 0 and 100, so if text box contains a number which is above 100, it will automatically change the number to the maximum number which is 100.
Does any one know how to code this in my function below in javascript:

I'd like to limit the number of selections a user can make in a
multiple select listbox. I have a note on the interface to say that
only x no. of items should be selected and I check the number server
side but I'd like to implement some javascript to do the same on the
client side. Ideally I'd like the javascript to work in IE5+ and
Netscape6+.
is it possible to limit the number of displayed items in a dropdown list? for example list of countries will display only 5 and people scroll down to see the rest of the list?

ah, i've just looked into the operators in more details and -= is just for numbers... so this won't work. i presume this is going to be the wrong method then.
what i can use to countdown the number of chars that a user enters in a text box?
Take a look at this page:-
[URL]
If you look at the textboxes towards to bottom of the page, you will see the limit of chars i allocate for e.g. (300)
Now how can i get this value to countdown when the user enters words?
Is it possible to use javascript to select everything in a textbox between two characters?
Example
;abc;def;ghi;
When the user clicks anywhere between abc then abc is highlighted.
I want to count the characters in a string. The problem here is, the 'return key' i.e if 'enter key' should be counted as 2 instead as 1 character.
I tried few logics but none of them worked out. I tried with php ajax too. It worked fine in firefox but not in IE.
Here is the logic i used. When onkeyup call the js function.. which calls the php page by passing the string as encodeURIComponent(str).
Now, I took the string in php and counted the in the string and added the no of occurrence of to the string length.
My concern is, IE is returning 3 for return key instead of 2.
i am trying to check a character with another character which are in the same text box.when we are entering date,date in the first text box and month in another text box and year in another text box.now i want when i am trying to enter '0'in the character position when there is '0' at first character position it must raise an alert box as well as when i am trying to enter a digit greater than '1' at 2nd character position it must raise an alert box when there is '3' in the first character position.

How can i display this value within a textbox?

View 6 Replies View RelatedWhat I'm looking to do with the following form is when a user inputs a certain length width and depth the output will be set to a certain number of characters. Basically looking to add a zero before an input of a number lower than 10 in two fields (product_number & product_id)
For example if a user inputs:
The output I would like to have would be:
Right now the output looks like this:
The reason for this is so when I sort my products in my shop they will go in the correct numerical order as well as making everything easier to maintain. I only need it to be 2 digits before the decimal point because the max number input will never be over 99...
Here is the code:

how can i disable special characters in a textbox/textarea?
View 10 Replies View RelatedI 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.
[Code]...
I am trying to figure out how to submit a form via javascript, when a user enters in 9 characters into a text field. Can't seem to find out how to do this...
View 5 Replies View RelatedI 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;
