How do I onBlur prompt the user to enter a ZERO as character one, if one is
not already entered. At the same time, I would like to ensure at least 5t
characters have been entered. This validation should also only trigger if
anything is entered. Basically, if the user chooses to enter nothing then
the check should not be carried out and the user should be able to continue.
So in pseudo style:
If user data IS ENTERED AND DOES NOT contain a ZERO as first character, or
is LESS THAN 5 characters long, prompt for re-entry.
Thanks guys, been trying various things and got close, but have hit a brick
wall.
This ALMOST works:
function checkField()
{if (document.form1.Bsk01.value.length<9) {alert("Please enter a valid code.
The first character should be a zero.")}else if
(/^0.*$/.test(document.form1.Bsk01.value)){return;}else{al ert("Please enter
a valid code. The first character should be a zero.")}}
I'm not a JS expert, but is there any way to detect if there is a certain character at the ending of a sentence in a text input field?
for example, when a user puts "Hello, my name is Gary" into a certain text input with a specific ID and using the JS OnChange event, the script will add a period ( . ) if it is not detected.
or, when a period is detected at the end of the sentence ("Hello, my name is Gary."), it won't do anything.
I got this idea from reading the W3 School onchange doc, but I'm not sure if it's possible.
I 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 have an input type=text with value={date}. User scrolls his mouse wheel on it. I need to see what is character number in the text field (in Firefox it's evt.rangeOffset). How to get that in Chrome?

I have a web form with several fields. If I copy & paste from a RTF document into a field, the javascript validation and field length are bypassed and cause the form to fail.
Just wondering if anyone knew how to make it so that if someone types an apostrophe in a form's textbox, a popup box appears. The popup box would preferably appear the second that the apostrophe is entered int he form box and then once the popup box is closed, the apostrophe is deleted.
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 think this will help people a lot, cuz i couldn't find any simple answer by googling 3 hours...i need a very very simple jquery form field reset.here is the picture what i need:
HTML Code: <script type='text/javascript' src='http://code.jquery.com/jquery-1.6.4.min.js'></script> <script>
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:
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?

In my application (yes I know that it's asp) I need to automatically replace a character if it is found in the textbox Is there a way to do this. this is how it renders on the page
The following form validation script works, currently if one of the five fields are completed, a message appears the remaining field(s) must be completed etc. Although the information the user has inputted in the first field is cleared. How can this information be available, if there is one problem in the form it doesn't make sense that the user must re-input all the information again. I look forward to hearing your response,
my javascript code is only validating one field at a time (as in it validates on field then submits the form, instead of going through the entire thing and then returning it as true and submitting it...) I'm not sure what to do to be honest, I've looked up google to no real avail.. my variables are declared in a seperate file to the actual even handlers and I have heaps of comments through out it, so please don't judge lol i'm still learning Quote:
//Event Registrations (Variable Declarations) found in validation_chkr.js //Validate Entire Form using validate_join() function validate_join()
Is there a way I can calculate a field in a form based on another field in the same form. When clicking submit, both values should be posted to the next page. I want to be able to type in a value in one field, and automatically in a second field the value*1,36 should appear.
I have a site for property bookings with 2 calendars to enter start and end date. The calendar im using doesnt have any obvious facility to copy yhe date to 2 fields so each one has to be done, months in advance this can be a real pain.
Does anyone have any ideas how i can take the data inserted into one field and copy it to the second?
I've have a function to take the value entered in a form text box, add 50 to it and put the result in another text box.
When I enter 650.5 I get 700.5 exactly how I'd expect. But when I enter -650.5 instead of getting -600.5 I get -650.050 as though it is failing to parse the float due to it being negative. My understanding of parseFloat was that it recognises negative numbers. Is there a nice simple way to get this to work?
I need to pass user input from a form to one database field. I'm relatively new to JS but the idea I had was to have several form elements and use JS to collect the users input and send all the values through a hidden element. What's happening is the variable names are being sent rather than the values. The code below is only passing to the next page. Limitations: I am editing an intranet site built by a 3rd party so a lot of the files we've been given are encrypted. I cannot change the method to post.
I work for a very large company that has zero communications between IT and the employees...so there is very little possibility of having any code changed.I need to use a web based system that submits orders for my department. The problem is i must order by "task number". I could have 20-30 task numbers so to complete the order I need to go to my company's page and fill out 15 form fields and submit for each task code. It is a terrible pain. 14 of the 15 fields are the same for each order... only the task code changes.
I've set up a mock registration form page so I can learn a bit about javascript's form validation. (newbie) I want to try to attempt to style the border of a form field green when the user enters the correct info into the form text field and red on all other fields if the user doesnt enter any info into them. When i test it, enter the right info into the username field, leave the others blank, and hit the submit button it styles the username field green ok but it doesnt make the next fields (password and so on) red. just for testing purposes I've put return false on everything so it displays a message when everythings ok.[code]
Am creating a framed chat application and when the user types a message in the form field and clicks the submit button, the message gets sent to the display frame, but the message stays in the form field. How can i get the form to submit the message AND reset the form field to blank too?
I'm trying to do some javascript form validation and I've discovered a rather difficult situation to handle with IE.
Let's say there's a form with three input fields named "name", "method", or "length". Whenever my javascript tries to access the form's name or length, and the form happens to have input fields named "name" and "length", I'm actually accessing the input fields and there seems to be no way to access those properties of the form.
I have an easy workaround for form.length, so there's no need to give me a workaround for that one, but there's a bigger issue with fields like name, method, action, etc.
For example, using document.forms[0].name to get the name of the form seems to map to document.forms[0].elements["name"] istead of the actual name of the form. Is there a work around for this? I am writing some generic form validation code, and I can't expect the person implementing my form validation code to avoid using "name" and "length" as names for their form fields.
