The following Javascript will return an error message if the user did not enter any value into the zip code field. The form will submit even if user entered only 1 character. Does anyone know how to change this to at least minimum 5 characters must be entered into the field?

I use the following to verify that a user has entered a number between 0 and 99 in a form:
It seems to work fine in all browser / machine combos except Firefox on a Mac, when entering 0 returns false (I don't know if entering other numbers also returns false.)
I am using this code to validate a form to check that only numbers have been entered but when I enter alphabets the javascript raises an error but still submits the form.
<script type='text/javascript'>
function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}}
</script>
<form>
Numbers Only: <input type='text' id='numbers' action= "desktop.html"/>
<input type='button'
onclick="isNumeric(document.getElementById('numbers'), 'Numbers Only Please')"
value='Check Field' />
</form>
I have this form validation code
function check_email(mailstring)
{
valid = "1234567890qwertyuiop[]asdfghjklzxcvbnm.@-_QWERTYUIOPASDFGHJKLZXCVBNM";
for(i=0; i < mailstring.length ;i++)
[Code]....
at the moment its checks that someting has been enetered in all these fields,
what would be the best way to check that the email or phone nummber had been entered?? will not send if nothing enetered, but will send if one or both have been enetered?
I have a HTML form which takes some values including a password field. I have a JS function to check and alert when a user enters some particular special characters(this is bcoz only these characters are not allowed in the back end of the html form, all the other special characters are allowed). following is the code for it.
function checklen()
{
var iChars = "`<>";
for (var i = 0; i < document.ipform.password.value.length; i++) {
[Code]...
now i want a feature which does'nt allow the user to enter an uppercase letter or a special character(only these are allowed~@#$%^&*()-_+|) as the the first character of the password field. Since i am newbie to JS, It would be a great help if some one can help me to sort out this..
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
View 6 Replies View RelatedI have a text area in one of my forms that I want to control the character size of. In short, I want to keep the text area to 10,000 characters.
What I Have Found: I have found a number of scripts that will control the character length of the text area, while you are typing.
The Problem: If you cut and paste a document that contains 15,000 characters into the text area that is limited to 10,000 characters, it will still take all of the information (i.e. the 15,000 characters), as opposed to limiting/cutting it off.
Does anyone know of a script that will control the overall character length whether it be inserted via key stroke or is copy and pasted into the text area? Or possibly point me in the right direction?
I using the jquery_validate.js script to validate my registration page. Does a great job, but I need to increase the length of password characters from 6 to 8, with at least one number. This is the message a user gets:
HTML Code: Please enter at least 6 characters. I'm quite new to jQuery and I looked at the jQuery validation page and couldn't figure out how to change the parameters. It's suppose to be easy to modified by I'm at a loss as to how to change the rule from 6 to 8 and include a number.
I am working on a Phone Number Form. The link of script: [url]
Questions:
(1)I wanted to know if code this script so that instead of the phone number appearing as: (123)456-7890
So that it appears as: (123) 456-7890 with a blank space after the ")"
(2)If that's simple, is there a way to error-check it so that only numbers can be entered into the phone number input field?
I am constructing an HTML questionnaire and one of the questions
requires people to rate some choices from 1 to 5, where 1 is their
favourite and 5 is their least favourite:
Car
Bus
Taxi cab
Train
Airplane
Each choice has an INPUT TYPE=TEXT tag to contain the response. I
also have a function that is called ONCHANGE in order to check that a
number is entered between 1 and 5:
function CheckNos(obj) {
if(obj.value.match(/[^d]/) || obj.value<1 || obj.value>5)
{alert("Please enter a number between 1 and 5");obj.value="";return
false}
}
This works fine, but ideally I would like a function that could check
ONCHANGE that someone has not filled in the same number twice, for
example answered "1" for all of them. They are only allowed to use
each rating number once, so rating their choice 1 to 5.
Can anyone suggest a short function that could accomplish this easily?
Could I use some kind of array with 5 elements and allocate a flag
value once that number had been chosen, then check that the value had
been set?
I'm trying to create a button that when pressed will remove the last character entered in a text field called "cell" using jQuery. Here is what I have:
Code:
$("#backspace").click(function() {
$("#cell").value($("#cell").substring(0, $("#cell").length() - 1);
});
It doesn't work Can someone shed some light on what I'm doing wrong.
Heres my javascript code that will verify email from email input field and check if the checkbox (I agree condition) was checked:
[Code]....
However, this will work fine when calling with a link "javascript:validate('inputForm');" but if I try to prevent users by submitting form with pressing enter I put it in form onSubmit parameter: <form .. onSubmit="javascript:validate('inputForm');"> which will check the forms and submit data (do return) no matter if it matched or no.
So the following code hides/shows fields in a form when radio buttons are clicked, the problem is on the same form I have a checkbox and when said check box is selected the showing and hiding of the fields doesn't work.
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">[code]...........
The function below results in this error and I'm not sure how to correct it? The initial value of the field is 0.00, but it doesn't look like it's relevant... That is, even when the value isn't 0, it still results in this error.
if($("input[name='b2h']")) {
$("input[name='b1']").bind("keyup", b2);
b2();
[code]....
I was just wondering how I could do this...
I currently have this
<span id="span_1">Title</span>
What I want to know is if the span is something like 240px in width how can I make it so if the text inside the span tag is to long and puts the text onto a second line how can i make a cut off point in the text to stop the text moving to a new line and adding '...' if the text is to long??

View 6 Replies View RelatedI am re-developing my website and want to use some Ajax/jQuery in it (so I am learning as I go) and I am not sure if this is possible so that is my first question:I have a registration form and I would like to know if after the person registering has completed their first and surname and the 2 sections of their postcode if I can use jQuery to run a PHP script to see if they are already registered before waiting for the form to be submitted and running a script then.I am thinking onkeyup (or similar) after the last field is completed but I don't know how that would work needing to also use 3 other field values.If this is possible, can anyone give me any ideas of examples that do this or how I can go about passing all the variables and running the scripts at the correct time.

I have a form that works out some basic math questions e.g. area etc. I run a function when a form field is updated to do the calculations, however I'd like to run a different calculation depending on which form element was updated. Is there a way to say something like:

work out this calculation
}
if(area2 was updated) {
work out this calculation
}
and so on?
