Validate Individual Text Field Validation On Form?
Jan 14, 2011
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 trying to figure out how to integrate jQuery Validation plugin with the qTip plugin [0] to show custom error message displays. I've had partial success with the following code:
At this point, that successfully displays the validation failure message in a qTip tooltip when it occurs, but there are two problems with it:
1) The error tooltip toggles between visible and invisible onmouseover and onmouseout. I'm sure this isn't really an issue with the Validation plugin, but rather something I need to figure out with the tooltip plugin. But, my bigger problem is...
2) Even when the invalid condition is fixed (valid data is later entered into the field), the error tooltip remains attached to the field that was previously invalid, even after the field is valid, and continues to toggle between visible and invisible onmouseover and onmouseout. I'm fairly certain that this is because I've not yet destroyed the tooltip object, but, I can't seem to figure out a way to intercept the "valid" or "success" event with a reference to the element so that I *can* destroy the attached tooltip object.any experience with combining qTip with Validation, or, if I'm missing something in the docs (I've not been able to find anything like this yet) about how to handle/override event handlers for individual form element invalidation/success. I *did* try attaching a function to the "success" attribute of the validate function, but that seems to only give me a reference to the success label, and not the element that its attached to.
I have a form (form1) to register with the fields: user, email, password being validated normally.
Have a second form (Form2) to the user update the data registered in form1, and the fields user, email, password is already populated with data from the database, the email field I use the remote validation, and as the field already has been completed and read always says that this email already exists, how do I create a rule or method so that when the field is already filled it not do so validating and validate if it is filled with a new email. Email2 have a hidden field in order to do a test type.
I have a form set up and I need to set the validation so if one option is selected from a picklist, they need to complete a text field as well.
This is the code i'm using:
Code:
Reason is a picklist, I want it to show the alert when option 1 from the picklist is selected and no text is in the Row_Number field.
If any of the other options are selected, I want to make sure the Row_Number field is blank.
As I said, I'm sure this is a very simple thing, but I been working on it for ages, and cannot get it to work, I get the alert every time the Row_Number field is blank.
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'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 form on my website and I want to validate the phone field. I found a good script to do it but I need to combine the script with the other validation that I have on my formadd this phone validation script into the other validations that I have so that it is just one javascript?Here is the phone validation script:

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
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've many dynamic form on my current project. One if them have a two radio button, acting a little bit like tabs. If you select the first radio, the end of the form change to display the "branche #1", and if you select the second radio button, the end of the form change to display the "branche #2".
Let recap with dummy code:
And now I will have to make 3 validations:
1) The first one for the common field.
2) The second one, if buyer is selected.
3) The third one, if seller is selected.
So the code should look like:
But is seem that only my common fields get validated. How should I handle that situation ?
I am trying to make form in dreamweaver with several text boxes. If the person doesn't fill out one or more of the boxes, I want an error message to come up which lists which boxes weren't filled out. If they ARE filled correctly, I want the page to redirect to a thanks page.This isn't online, and I'm new to coding. But its going ok, I just can't get the form to validate AND redirect if return true (or something???). I don't know how to do that. I've tried googling it, searching youtube tutes, and reading a few javascript books, but no joy.[code]
Using jQuery Validate to do it's job of validating a form. Problem is I need to get at least one phone number recorded in the form - either a Telephone or Mobile (Cell).Is there any inbuilt way of setting up the rules to do this?I have seen the Milk demo for the validate plugin where there's something similar, but the 'name' attribute is the same, something that's not going to be the same for two different text inputs.
I have a text field where a user can enter either a(n):American zip code (example: "02475")Canadian zip code (example: "A3F 4G6")A "city/state abbreviation" combination (example: "Toronto, ON", or "Las Vegas, NV")For the most part, users don't have much of a problem with the first two criteria, but some people have some trouble with the third, either by entering simply a state ("NB", or "Texas"), a city, or spelling out the state name "Chicago, Illinois". I need to put together some validation that makes sure that:
If the entered text is not an american or canadian zip code (IOW, if the entered text contains no numbers at all - in that case, move on to the next validation check)Check to see if the third to last character is non alphanumeric (if they entered the city/state combination correctly, there would be some sort of non-alphanumeric separator between the city and state abbreviation)if the entered text doesn't fit the criteria, return the error.
function hasNumbers(string) { var regex = /d/g; return regex.test(string); }
I hope this is the right place for my question. I have a working form and all iss great using this jQuery Form Validation PlugIn from brassistance. Now I got in trouble by having a Form which will get extended by user inputs. To explan in detail: I have a Form with static fields and so on. But then if the User selects in the form the amount of Persons, I append Name and Surename Text Fileds to the static form and give the form fileds dynamically generated names. now have the problem to validate the dynamically generated text fields in that form!
I'm trying to set up a form that has a text field that is required to be blank - I'm dealing with form spam, and the bots are stuffing every text field with random crap. So, I have a text box that is required to be blank. But I can't get jquery.validate to understand both required and blank.the text input is has a name and id of live_check.I have added this method:
$.validator.addMethod("equalToParam", function(value, element, param) {return value == param;});
I have a JS which validates the correct format for postcodes (or zip) on an html form - works fine.But what I want to do is to use a JS to see if a website visitor is eligible for a particular service on their postcode / zip - ie the first general part on the code. For example if they type L15****, or L16**** or L18 (where the asterisk could be anything) it pops up the alert box with a message saying "Yes eligible" but any other code returns "No sorry not eligible" - eg L19**** it returns nope.I've tried hacking the code that validates to format and can manage it for just the first character - ie the L but I'm totally lost after that. I don't know if hacking the below will work.
I wonder if anyone can assist me here. I am trying to find the best way to validate a field against another field. In this case I need to make sure when the user enters the date of birth that the date is not prior to another date in the database (admission date). I would like to do the validation on submit before the other data from the field is submitted to the database.
I have seen a lot of forms validation that can compare the inputted value to a range of values, but I need to say "is the birth date prior to the admission date? If NO then give a message to the user to recheck the date". Sounds easy, but I haven't found a clean way to do it.
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]
