JQuery :: Validate Optional Fields Only When Data Is Entered?
Oct 13, 2010
I'm using jQuery validation on a form and I can't get it to only validate optional fields if the user enters something (should recognize the difference between this and the default value of the field, for text input fields). I know this is built in (I think) but I must be doing something wrong.
For example, phone number is optional but I want it to validate if the user enters something. Code for the phone in the JS file is:
When I just put "phone" as the class it validates the field even if it is not edited by the user at all. For the required fields I put "required" as the class to validate them but I just read in another post that this is not necessary with the plugin...? I guess I am not sure whether the field should be define as optional by a class or in the JS file, and if it's the latter, how to do that.
When typing data into the autocomplete-field the list of matches is updated at every key pressed.Is it possible in any way to check and correct the data before doing the match. Or could you alter the way the match is done.The perfect example is when you have lots of users entering decimal values into a filed. Some people uses comma and some decimal-point. So you would like to permit both "2.23" and 2,23" to be matched against 2.23 in the list.[code]
im loading data via json dynamical from the server. Now i try to optimate the speed of my application and so i want to disable the validate of the fields during the data loading from the server.Is there a simple solution to this? like validate = false
I'm trying to make sure that when a user enters information into my textbox, that when the textbox loses focus then it checks to make sure that they entered numbers and not text or other characters. Numbers only....Any suggestions?
I 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 website where people can create posts similar to FB(I hate that example but it's widely known) -- how do I strip HTML tagging out of the post before I put it in my db? (I'm using AJAX atm).The obvious crossed my mind with replacing "<" and/or ">" but I want those chars to be available when posting -- is there a way to do this or a way to print the data to my page as text even if it has those tags?
How can I validate a collection of fields, instead of validating the whole form? I'm using asp.net which uses one form element, which I even don't use. I have a tab panel with on each tab a couple of fields. I only want to validate the fields on a tab.
I have an ASP page that displays, along with other data, a list of items that refer to a specific element in a database. Instead of adding an Add button, I would like to display a text box below the last item in the list to have the user input any new data. Once they enter the data and hit Enter, the data they enter should then be added to the list and another text box added beneath this item (just as forms and tables in Access do). However, I'm not sure how to implement this functionality.
I am using jquery.validate.js. I am having 2 input fields. The condition is the second input value should not be less than first input value. The second condition is the first input value should not be greater than 2nd value. I tried with different options but it didnt work. Is there any jquery function for this validation? Or pl
I'm validating a form using jQuery validation. or that I only add an specific class to the fields ("required","email",etc..). Ex: <input id="form_linom" class="required" type="text" value="" name="form_linom" size="50"> Since is a big and dynamic form (selections in some fields hide or show other fields) I have problems when submitting the form since validator doesn't permit send the data to the server because is validating also the hidden fields. The way I add the class to each field is making an array in PHP of all the required fields and then if the field is in that array the class is added. The only other thing that I put was this in the header:
I posted code in [URL].. look that the email field is hidden but prevent the form to be sent. I need a general rule that collect all the required fields that are hidden, not only the e-mail field as in the example (In my real form I have 54 fields).
I am trying to use jquery: validation plugin by Jörn Zaefferer. Which works really well I have to say. The one limitation I am trying to work around is how I can run validation for required fields before I submit a form. At the moment I have to submit the form before I see the error messages for required fields I would like to see them prior as the user tabs through the form.
Trying to use the [URL] I would like to beable to ignore default values, but am sort of stuck. I already looked through all 42 results after searching for how to validate while ignoring default value. I have tried:
im using Jquery.validate, and I have a particular issue, jquery plugin is validating fields which didn't have rules. this is my code. Im attaching my code.Display name, First and Last name works fine. The wrong behavior is when I change DDL values and Do click elsewhere in the page, the minlenght validation activates for the dropdown lists.
I am using jquery validation plugin successfully to validate certain fields against my server. The thing is sometimes user types too fast, and the validation plugin sends the word if not equal to the previously sent word. This causes some problems with my mod-evasive that I run in apache. Is there anyway to slow down these requests, or say post to server each 300ms. The jquery UI autosuggest has this feature, where you can set a delay time.
My CMS generates forms in a specific way, and I need to change the way validated fields are selected. I'm using the validation plugin: It identifies form fields that have the "required" class. My CMS generates required elements like this:
<div class="required"><input /></div>
I was hoping this can be easily changed in the plugin syntax, but I can't find any reference to such a change (to select the required fields using this selector: ".required input"[where input is any form element])
I have a simplified version below of a multipart form. There are two steps and two tabs. I want the user to enter their username and email address and click 'Next' which will validate to make sure those fields are filled in, then activate and advance to tab #2 (Step #2) of the form, where they enter their credit card information.
I am having difficulty because username, email and credit card are all in the same form and I need to only validate certain fields on each step of the form. I was thinking I could make a function when the 'Next' button was hit that would validate the first two fields?
Here is what I have so far. I have a 'Next' button which activates and advances the tab to Step #2, but I need to work some form of validation into it before it advances. At the bottom of the page I have a 'Submit' button which is just so you can see that the validation is working if the form is submitted. I just want the 'Next' button to activate a function to only validate the fields on Step #1 (username/email).
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 a newby who has manage to get up and running rather quickly and with ease using the documentation. My form validates as expected but it shows the default error messages and highlights the invalid fields. How can I suppress the error messages?
