Form Validation Field Values Not Saved If One Field Is Not Completed/invalid?
Feb 3, 2009
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,
I have 2 fields in a form, field1 is type hidden while field2 is type text.Both will have numbers in them. I need to compare these 2 in my form validation and having issues getting it to work right. If I do something similar to the following:if ((passForm.field1.value) < (passForm.field2.value) ) {alert.....It runs, but is running the validation, but is reading the values as text and literally left to right.
so for example If field1 = 12 and field2=3 it does not run the alert (wrong) If field1 = 12 and field2=100 it runs the alert (wrong)
I've been building up my validation using the jquery validation plugin but I can't work out how to get a failed validation to default the focus to the first invalid input rather than to the last selected input. If there is no input field selected, when I submit then a failed validation will focus the cursor on the first field but if the cursor was left in a field and submitted then the focus stays there (if it's invalid) rather than jump to the first invalid input. From what I've read and seen, this is the expected behaviour but not what I want. Is there a way I can get the first invalid field and set the focus to that?
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.
i am creating a simple form validation script where i will ask for the username, password and email of a user. when an error is created, a text will be displayed beside the textbox. but i want to know how i can add colors to the textbox if there is an error.
I'm a little curious with regards to alerting a user to invalid data in a form field through inline alerts, rather than alert boxes and without a page load.In otherwords, if someone types in invalid data into a form field, before they hit the submit button, I'd like to use javascript the insert some red text on the side saying "this is invalid".I'm concerned that people with visual disabilities wont notice it due to their screen readers.I.e. if the screen doesn't re-load, will the screen read read the nexly inserted text or will it not do anything until a new page loads?
I need to validate two forms containing multiple input fields but want just one error message if any of the fields are left blank, the page is required to submit the users details (registration form). Also if any of these fields are left blank i don't want to be able to go to the next page on clicking the submit button
Form validationhaving had a number of responses to my initial request for a template for a simple client-side JavaScript form with basic field validation it seems that this simple request is far from simple.so, collating all of the not-so-simple comments that I have had heres a revised request
Is there anywhere that I can find a template JS script that will provide me with a form that has the most basic of fields on it first name, surname, telephone.e-mail etc that comes with field validation? The users will predominantly have hotmail, yahoo etc e-mail addresses Not all of them will have IE web browsers Not all of them will have Outlook Express as their mail client
The form fields MUST BE VALIDATED ON THE CLIENT-SIDE as there is no server-sideaccess and the site that the form is then be posted to will only accept validated field data. Or would it be simpler for someone to provide me with plans for a engine that would provide light-speed.?
I have some problems with validating form in javascript.
I have a following HTML code:
What I want in validation is to check all the field in form (check for required fields etc). I want to show user error message in div tag with id='poruka'.
Part of code of function ValidirajFormu:
So, validation works OK, but message is not written in div tag. Only if all fields are correct, form is submited, but there are no error message.
My HTML with Javascript I had a problem with the form submittion.. where the javascript working fine for validation after completing validation my form submit is not processing to action specified in the form tag.
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]
Ajax and jQuery is something I'm new to, but PHP, Javascript, and MySQL I'm pretty well seasoned with.For starters, I want to create a simple form where there are these fields:Name (text field)E-mail (text feld)Zip Code (text field)Cell Phone Number (text field)Phone Carrier (dropdown menu)Thing is, I want to check the database to see if an e-mail address has already been entered. I'd like for that to happen after they enter the email address and tab or click out of the e-mail text field. For instance, after they enter an e-mail address and tab to the Zip Code field, the script queries the database to see if that e-mail exists already. If it does, it notifies the user and greys out the submit button. If not, they're allowed to finish filling the form out and submit. It'll be a huge time saver if this Ajax script is in place.
I have an order form where a customer can select a number of artwork prints supplied by different artists and suppliers. The name, price, postage amount and other details for each of the prints are held in a table in a MySQL database. As postage amount may vary between prints and suppliers of the prints we must have the customer select postage per print - not the amount just yes or no. The customer may select as many of these prints as he desires - printa, printb, printc, printd etc. through to printz. Many of the prints are provided by separate individual suppliers and must therefore have postage paid for each ordered print and this is automatically added by the order form. However some prints are provided by the same supplier and only one postage fee needs to be chosen (yes or no), so these are not automatically added and the customer must choose to pay postage on only one of the prints (not all 3 if he orders 3 of them).
So for postage purposes I have a postage code on the table in the MySQL database. For example printa, printb and printc are all supplied by the same supplier so each have a linked postage code of A. Similarly others may also be linked using different postage codes e.g. printx and printy may have a postage code of B. So whenever a customer chooses a print that does not have a linked postage code then the postage fee is automatically selected for him and charged to the total. However where prints are linked to the same postage code we must allow the costomer to select postage (yes or no), but we must force him to select yes or no for at least one of the linked prints.
So to do this I need a javascript validation alert to force the customer to choose yes for postage for at least one of the prints, not necessarily all of them, where they have a linked postage code. To do that I can add the the postage linked code as an array for each print selected to a form hidden field so that my javascript can use the field as follows: <input type="hidden" name="postagearray[]" value="<? echo $postagecode; ?>">
Not exactly sure this is the right forum to post this but just to give it a shot.I am relatively new to programmming...I am currently working on a web appliation using MySQL DB and use PHP/SQL.I have a web form i have created. What i want to achieve is that when a user fills in one of the fields...a text field, i want 8 other fields to be AUTO filled with different values related to the one the user filled in
want to swap the contents of two textarea fields in my form when a hyperlink is clicked.i have the hyperlink and layout donw just want to know how i access and set the form fields to their new values,
I'm trying to implement a validation in my form, but that should not be bound to an specific field. in fact, I have three input type=text, and I need at least one of them to be filled (like a conditional 'required').
I have a scenario where I have the following jquery Code: $("#frompdc<?php echo $JavaCnt;?>").change(function(){ var id = $('#id<?php echo $JavaCnt;?>').attr('value'); var frompdc = $('#frompdc<?php echo $JavaCnt;?>').attr('value'); var topdc = $('#topdc<?php echo $JavaCnt;?>').attr('value'); $.ajax({ type: "POST", url: "AJ_Update.php", data: "firm=y&id="+ id + "&frompdc=" + frompdc&topdc=" + topdc });
And some php to insert this data Code: mysql_query("UPDATE TBLTRANSFERS SET FROMPDC = ".$_POST['frompdc'].", MOD_TS = '". $timenow ."' WHERE ID = ".$_POST['id']);
I'm trying to throw some validation in here which I can do in php (a language that I'm much more proficient in) but can't figure out how to get the two together. I want to be able to do a select against another table I have for both the frompdc and the topdc. Code: $tofpdcresult = mysql_query("SELECT * FROM tbltransferspdcexclusions where FROMPDC = '".$frompdc."' AND TOPDC = '".$topdc."'"); $tofpdcnum_rows = mysql_num_rows($tofpdcresult); And if it exists I want to give a popup message to the user as well as blank out the field.
I'm struggling with two things: How do I get ajax to run two queries and return the results to a popup window? How do I blank out the field in the form?
I need to get the invalid fields to change back to blue when they're validated upon submit or even clicking out of the field.I'm not good in writing javascript yet so please include all of the javascript and html with the edits highlighted in the code:
The page: http://shoppingcartcash.com The js: http://shoppingcartcash.com/form.js
I have written a form in HTML which contains username,lastname,email,password and submit.I have written a javascript to validate this form [validate(username,lastname,,password)].On submit this javascript function will be called and hence form get validated. I am passing all the arguements(username,lastname,email and password) to the javascript function..Is it possible to make me a code such that it should call an individual function for each field in the form.for ex:if i have not entered username, last name in the form and attempt to submit, only username arguement should be passed to the function as it comes first in the form.In other sense i want to validate individual text field validation of my form.
I'm only validating one (Consent) radio button with this code but I need to validate multiple different questions/buttons.
<script> function getRBtnName(GrpName) { var sel = document.getElementsByName(GrpName); var fnd = -1; var str = ''; for (var i=0; i<sel.length; i++) { if (sel[i].checked == true) { str = sel[i].value; fnd = i; } } return fnd; }
function checkForm() { var chosen = getRBtnName('Consent'); if (chosen < 0) { alert( "Please choose one answer when you are asked to select a number." ); return false; } else { return true; } }
</script> <form action="congratulations_aff.php" method="post" name="congratulations_aff" onSubmit="return checkForm()"> <table border="0" cellspacing="1" cellpadding="0"> <tr> <td colspan="3">I consent to providing my electronic signature.</p></td> </tr> <tr> <td colspan="3" valign="top"> <input type="radio" name="Consent" value="Y" /> Yes <input type="radio" name="Consent" value="N" /> No
<table border="0" cellspacing="1" cellpadding="0"> <tr> <td>I consent to electronic receipt of my information reporting documentation.</td> </tr> <tr> <td valign="top"> <input type="radio" name="Consent1099YesNo" value="Y" /> Yes <input type="radio" name="Consent1099YesNo" value="N" /> No</td> </tr> <tr> <td valign="top">
For tax purposes are you a U.S. citizen, U.S. resident, U.S. partnership, or U.S. corporation? <input type="radio" name="USPersonYesNo" value="Y" /> Yes <input type="radio" name="USPersonYesNo" value="N" /> No </tr> </table> <input type="submit" value="submit" value="Submit" /> </form>
I have managed to create a very basic form validation script that I can retrospectively add into current forms with the least effort.
As far as the validation goes I am sure that the script is not pretty, but it does work. However, I have failed to manage to get it to return the focus to the first field that errors.
My abortive attempts are not included in the attached script because I have tried and failed with many different attempts that I have confused myself. I would appreciate any advice that could point me in the right direction to place the focus in the first error field found. Code:
Can anyone tell me how i can change which attribute on my form field triggers the validation?currently it appears the be the name attribute. So in my Rails app using Rails helpers, it sets the name to somthing like formname['fieldname'] and the whole name.in my script if i do something like [codde]it causes the script to break.
