Ok, I am (still) trying to validate this form's username and make sure it contains no spaces and no special characters. I've been trying forever now... Can you point me in the right direction or get me out of this hole please? Code:
View 2 RepliesI want to remove special characters in form fields. It should be automatic. I have a name filed where user entering text and i not want special characters, it should remove automatic.
something like this i need,
onkeyup="javascript:this.value=this.value.replace(/[^0-9]/g, '');"
here, all non-digits get removed automatic.
JavaScript solution for show text statistic like this online-utility.org/text/analyzer.jsp

I need to validate the form, I am getting started by validating a simple username field. I have written the code but it does not seem to work for me.
Code:

<html><head>
<meta name="generator" content="HTML Tidy, see [URL]">

return true;

I 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*$/;
!Uidalph.test(document.form.userUid.value)) {
buildErrMsg( "Username","Invalid characters")
i m using the following validation code to validate email id
if (!/^w+([.-]?w+)*@w+([.-]?w+)*(.w{2,4})+$/.test(document.getElementById("customer_name").value))
{
msg=msg+"Must Enter a valid Login-id/Email
";
document.getElementById("customer_name").focus();
}
now i need that if the email id contains white blank space in front of email id or end of email id then this validation should pass otherwise not.
at present if there is blank space in front and end of email id then the validation doesnt passes and gives alert.
what should i add in it to validate it or how can it automatically remove white spaces before validating.
I have a javascript function which checks if the user has enteed certain text into an input or if they have entered any text at all before the submit button which submits the text is able to be activated. How can I enhance this so that if the user no text at all and only enters several spaces this will also not be allowed and will return false?

I have a Javascript which is to count the number of characters entered into a Textarea box and to prevent any more characters from being added after a certain number has been reached. Here is the code:

I have to validate this stupid form as well as check to see if there is cookies and add them if they haven't. I know most of you probably are pros at this! So I am requesting some assistance. Please see the code attached, let me know what to do. As well I can't get something that will work with my radio buttons to validate as well as cookies. Code:
View 1 Replies View RelatedIn another thread I found that a good way to show and hide parts of a form based on previous entries would be as follows:
function showhidefield (method) {
var hideablearea = document.getElementById("hideablearea");
var hideablearea2 = document.getElementById("hideablearea2");
var hideablearea3 = document.getElementById("hideablearea3");
switch (method) {
case "1":
hideablearea.style.display = 'block';
hideablearea2.style.display = 'none';
hideablearea3.style.display = 'none';
break;
case "2":
hideablearea.style.display = "none";
hideablearea2.style.display = "block";
hideablearea3.style.display = "block";
break;
case "3":
hideablearea.style.display = "block";
hideablearea2.style.display = "block";
hideablearea3.style.display = "block";
break;
default:
hideablearea.style.display = "none";
hideablearea2.style.display = "none";
hideablearea3.style.display = "none";
}}
I know how to use javascript to validate that the forms are infact filled but how do I make it so that it doesn't scan the hidden forms. The only way I could think of would be a huge bunch of if statements. Is there any other way to do this?
I have a database that shows about 5 to 10 recorrds on a page that contain forms for the user to fill out. The number of rows is unknown and depends on the user query.On the page there can be 2 or 10 records displayed ..each containing a form that needs to be validated.How can i use that. The IDs of the elements would have to be generated dynamicly i suppose. Anyone of you got an idea how to do that ?

I am looking for a way to validate all forms throughout a website
through one validation script.
How do I determine the form's name (or id) value to implement
conditional validation?
i.e. if (form1) { validate like this }; if (form2) { validate like
this };
I'm currently working on a website called 'eXtreme Gaming' I've almost completed it, apart from two things.
- Adding two values on my checkout page for the Grandtotal (I've tried everything, but I'm too much of a noob and have probably missed something small).
- Validation of forms (I don't know where to start here, I've looked on w3schools for tuts etc but I'm having difficulty incorporating it on my site)
I have a php page with java script embed in it, i have 3 forms in a single page ... namely form1, form2, form3 . form 1 and form2 have a text box , these text boxes get input from users. Now my task is to get the value of these 2 tex boxes in form3 when the user click the submit button, so that i pass the values in those text boxes to next page for calculation.
I tried the following code in form3 but it result in vain :
Filename: summary.htm
Supporting files: back.jpg, edge.jpg, links.jpg, logo.jpg, summary.css

Code:
<title>Conference Summary Page</title>
<link href="summary.css" rel="stylesheet" type="text/css" />
<script type="text/javascript">
var searchString = location.search.slice(1);
var formString = searchString.replace(/+/g, " ");
var dataString = unescape(formString);
data = dataString.split(/[&=]/g);

I'm brand new to jQuery, and I am really interested in learning about it because of the potential it offers to enhance my webpages. To give you some background, I am self-taught in PHP and MySQL...not on a master's level, but I have designed and built database-driven sites with success and am confident that I can learn jQuery if only I could get pointed in the right direction. I have perused tutorials, links, forums and recently bought the jQuery Cookbook (I needed SOMETHING to go on and it was one of the few jQuery books at the local bookstore that felt as though it would be of help). My problem is, I am finding gaps in information that, to me, are critical to learning. I am looking for a nut-and-bolt approach, 'Do this, then do that' not the typical generalizations I keep encountering.
All I want to do to start with is to remotely validate a two-item form, you guessed it, username and email, against the contents of my database (the info for the validation plugins is just as vague and general). That's it. But the tutorials and examples are vague to me, and in one instance, a link was posted offering to display the server-side validation code used and the link was dead. I can't be the only person here who is stonewalled by these thoughtful, yet overly-general tutorials and books. if any of you have suggestions where I can find a concise, true step-by-step tutorial or book, I would love to know. Right now, it's just one frustrating day of research after another.
I have built out a fairly rhobust app using jquery and jquery-ui all was going well until we started to bring different screens together inside a tabbed interface. Seems that now when we execute our validation code on one form its checking the fields of all other forms on the page.All of my forms do have unique ID's and all elements within all forms have unique ID's.My understanding of using this.find inside of the submit event was that it should only find the forms elements am I wrong? Method that performs the actual validation:
function validateForm(event){
var allOk = true;
$(this).find("*[validation]").each(function(){[code]....
JQuery newbie question re using validation plugin with Django newform.I have a simple email feedback contact django form that I wanted toenhance with some JQuery validation. I created a standalone (NonDjango) version of the form and it works correctly.However when I create a Django version of the form the validationrules seems to be ignored and the form is always posted - I wouldexpect the form to fail, and never post. One difference (not sure ifit's siignificant) is that the Django forms are created from classes/templates and render as tables. However the exact same HTML code worksfor the basic form.I'm now thinking that there must be something different re how thesubmit is being processed for the Django form - but I'm stumped.
View 4 Replies View RelatedI've used the excellent validate plugin (http://bassistance.de/jquery-plugins/jquery-plugin-validation/) to add JS validation to forms. I'm aware there's a built-in setting to validate an email address. However, I'd like to validate a list of email addresses, and I don't think the plugin contains a built-in solution. What's the best way to implement this?
View 1 Replies View RelatedI know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client.For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead.
What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once?Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it.I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying.
I want to make few forms but 1 submit button. I want to do 1 page , 5 forms , 1 submit button so when i click on the submit button it will send the 5 forms as 1 form.
View 2 Replies View Relatedhow to add forms in javascript, but it's limited to text input forms.
<script type="text/javascript"><!--
function updatesum() {
document.form.sum.value = (document.form.sum1.value -0) + (document.form.sum2.value -0);
}
//--></script>
Where the inputs sum1 and sum2 are text fields you put whatever numbers you want in. That works fine. Great. Now what I'm having trouble with is modifying the code so that it will add one form with an input number with a form that spits out a randomly generated number.
<input type="button" value="D20" onclick="this.form.display.value = Math.round (20 * Math.random())" class="buttonHi" /> <input name="display" type="text" size="6" value="" />
This is what I'm using for my random number generator. So basically I want to be able to put, say, 5, into the input text field above this. And then click on the d20 button to get a random number, say, 15, and then have the first code add the inputted 5 with the randomly generated 15.
What I'd to know is how to refer to characters from different charsets like Herbrew or Japanese characters simultaneously, as well as English and all others within the same script block.
E.g,
[code]
if ( xx[K]=="C" ) { N = 1;}
if ( xx[K]=="荐" ) { N = 2;}
[code]
note that I'm using notepad which would never accept the Chinese character shown and that code only represents my intention. I'd gladly use a html value like .
