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 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)

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 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">
This is in regards to Jrn Zaefferer's plug in.How do you customize input validation so that I can remove foullanguage?So that first name or last name doesn't have "fck you" or something

View 2 Replies View RelatedI am new to JSP programming and was trying to do some validation on my JSP page as follows:
Special characters : ><&"'()#%;+-
The above mentioned characters needs to be validated at the client side. I am using the expression
var Uidalph = /^w*>*w*$/;
!Uidalph.test(document.form.userUid.value)) {
buildErrMsg( "Username","Invalid characters")
With the code I had to acknowledge nothing had been inserted,(that is, still spaces, it was working. When I added the code to only accept alpha chars etc., I inserted numbers, nothing worked, with no error message. Would you, or can I send the whole code through for the form. I noticed that the form tags had been changed so I altered them as well according to your message.

How I can output the characters as they are inputted into an input box...
View 4 Replies View RelatedI am having trouble with some javascript code that checks the first 2 letters of what the user inputs and whether it equals a certain set of characters. If the user for instance types in 'TT' in an input field, then i want the holding div to disappear, if anything else is typed in then this action wont happen. My code is below:
Code:
<script type="text/javascript">
function checkCode() {
var x=document.forms["myform"]["code"].value.substring(0, 2);
if (x == 'TT')
[Code]...
I believe the problem lies in the javascript line: "if (x == 'TT')", as the rest of the script responds but it just doesnt recognise whether 'x' starts with 'TT'

View 5 Replies View RelatedI have an email which has some values attached to a link in the email that get passed to an online form on a website when clicked. Problem is the value is a price and the string includes a "$" which I need to remove. I've read through many examples and everyone seems to have an opinion (surprise). One suggests something like this: text2.value=text1.value.replace(/$/g,""); While someone else says its better to remove what you don't want. I am also scratching my head over should I place the value into a hidden field, scrub it then copy that into the proper field? and I imagine the best way would be to run it with an "onload" command instead or a event handler like a keystroke since the field is not typed?

How can I do validation on a group of input fields, as long as one of the 3 fields have a value then it's valid,I've managed to group them, but it's showing up with 3 error messages instead of one. How can I get it to display just the one error msg for all 3 input fields?
View 1 Replies View RelatedI am using the jquery plugin and want the validation to upload only extension .doc but it does not validates the HTML5 input file when the name has brackets.[code]
View 1 Replies View RelatedIs the validation plugin able to validate an input only instead of a whole form?I mean, is this lign correct :
$("#InputID").validate(
rules: "required"
);
I have the follow code:
<script type ="text/javascript" >
jQuery(document).ready(function() {
jQuery('#selectone').change(function() {
if(jQuery('#selectone option:selected').text() == 'General'){ jQuery("form[id=search]").attr('action', '/portal/search'); jQuery('form[id=search]').attr('id', 'cse-search-box1'); .....
But, W3C says: Line 150, Column 154: document type does not allow element "input" here
because I am using input inside of <script> and it's wrong.
I'm using jQuery Validation on my form with ajax submit, but for some reason the label error message is replacing my input field completely. I can't figure it out for the life of me... Here's my html/js. I'm using the default validation since i'm using the ajax submit. I've also tried the custom error's with no luck. Both the label.error and input are displayed as blocks.

I have the following html, field xxx requires a number from 0 to 100 when percentage is selected, and 0 to inifinity when dollar is selected.what's the best practice to setup validation for this?the key is to control the maximum value.I have tried depends expression in a max rule, but it doesn't seem that it can satisfy my requirement.
View 1 Replies View RelatedI'm using the jQuery form validation plugin along with the fileinput plugin which hides the initial input area, but uses <divs> and some styling /javascript to show the file input field.The issue I am having, is that the 'this field is required' text that is meant to show on submission, doesn't come up for the file input field, nor some checkboxes that I have in a table. I am guessing that this is because the code is needing the label to be RIGHT next to the element (in this case the file input or the checkbox) in order for the validation message to show..Are there any work arounds that anyone knows of so that I can get the error message to show?Is there a way to show the error message for required fields when they have a div wrapping them or anything wrapping them?
