JQuery :: Skip Validation For Fields With Empty Class
Oct 21, 2010
I am using the validate plugin with the defaultvalue plugin (empty fields given a default value and class of empty), and would like to use it together with the validator plugin. Is there a way to mark required fields with only the default value (and class empty) as invalid on submit?
E.g.: First_name field is required by validate, has a default value of "Enter your first name" and class of "empty" - how can I get the validator to mark this as invalid?
I've an input field in the form which is displayed based on the user selection. Initially it is set to 'display:none' and I do have a validation rule for that field.
How do I skip validation on this hidden input field and only validate when its displayed on the page.
I want to validate my forms when clicking only on submit button. Here is my code.
[Code]...
The problem is it fires the validation to every button in the form. how can I do the validation only for the submit button and skip the validation to other button clicks?
In 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");
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 am using jquery autocomplete to retrieve values from database I need to implement empty item validation the point is that if there is no value in database user can insert it with bottom which appears somewhere in form. I try to usesearch: function () but can't figure out how to catch item length.
Code: ,search: function(event, ui) { //Your ajax parameters... //success: function(data) { //No idea what format your data is in... // if(data['status'] == false) { //there is no result //if ( ui.item == '') //{ //alert(ui.item.value); //} if (ui.length < 2) { // handle no data case specially alert('test no date'); }
I want to prevent submitting a form if any of the field is empty. also if possible I would like to validate some basic things. All I want to use JQuery: How do I do that? I have no way and google points me to plugins. The things I want to do are lightweight and I don't need plugin Here is my form:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title>Login in Site</title> <link rel="stylesheet" type="text/css" href="/loginsys/site.css" /> [Code]...
First post here - I am trying to hide options in a form select field if they are empty. The code below works...but even I know it must be a horrid way of doing it! Anyone care to tidy it up for me? I would learn much from the experience,
I have a contact info form with about 16 fields. I need to hide a subset of fields for address when the end user either (1) tabs out of the subset group, (2) clicks anywhere outside the subset field group.
I do not want to hide the fields when the end-user is tabbing within the subset of address fields, yet the focusout handler is triggered when it shouldn't be.
I am building a registration page . If the user completes all the required field i load the info into the database but if there are missing fields I combined some javascript into php to display next to the empty field a note that it should be filled. This is my code...
I am trying to check and see if three fields are empty and if they are then to alert the user saying to fill in one of the three fields. I tried this:
if (StreetNumber.value.length == 0) { if (StreetName.value.length == 0) { if (City.value.length == 0) { alert("Please enter a street number, street name, or city.");
I am trying to test a form whether the fields are empty or not. If so, displays warning, doesn't proceed. Here is my javascript , and the forms.
/* Validate Forms */ function validate(){ var notify = document.getElementById('notification1'); if ( null == document.getElementById('usrname').value ||
[Code]....
The problem is it works only for the passwd, but not for the usrname, meaning when the username is empty it shows the message as i wanted but right after showing the notification, it is going to the action page. Since it is returning false, it is not supposed to proceed. For passwd, it is fine, it shows the warning and stops without proceeding action.jsp.
There are two input fields in a form, but only one of them is required, they are not required at the same time. Either A or B is required. ( A is required OR B is required). In other words, a user can input data to field A, or he can input data to filed B, but he can not input data to Both A and B at the same time. How to implement this constraint in Jquery form validation?
I'm using a web form with php. I want, that when user clicks submit button and it will be an error (some fields will be empty) then I want it to show a little popup window... A simple javascript popup window generator don't fits me, because I have a php function:
Code: <?php if( !$isHideForm ): global $sErr ; if( $sErr ) print "<br><a name='error'></a><center><font class='form_error' > $sErr</font></center><br> HERE SHOULD BE MY AUTO POPUP WINDOW"; $starColor = $sErr ? "#ff0000" : "#000000"; $style=" class='form_text' "; ?>
I am building some JS and would like to share my limitation. This is the code: Code JavaScript: <script language = "Javascript"> function onComposeSubmit() { var formDOMObj = document.Login; var TrocaImagem if (formDOMObj.email.value == "" || formDOMObj.anexo.value == "" ) alert("<%response.write Idioma.Item(Session("Idioma")&"_10")%>") TrocaImagem= "1" else TrocaImagem="0" return true; return false; // change button if TrocaImage="1" document.getElementById("submitButtonDiv").style.display = "none"; if (navigator.appName == "Microsoft Internet Explorer") { document.getElementById("progressBar").innerHTML = ""; document.getElementById("progressBar").style.display = "block"; document.getElementById("progressBar").innerHTML = "<img src='img/progressbar.gif' alt='Progress Bar'>"; } else { document.getElementById("progressBar").style.display = "block"; } else } </script>
Things I am trying to Do: - Check if email field isn't empty and check if the anexo field isn't empty. Actually I would like to have it separeted but I dunno how to do this. - If email and anexo isn't empty run the change button part of the code, witch will change the submit button for a progressbar.gif image. Actually this part of the code works great but without the field validation above.
I have a CMS website that has a pop up upload panel that you use to upload a file into the website. It has a location field which you press browse to locate a file on your computer and then the field will be filled with the pathway to that file and it has an upload button.You locate the first file, press upload, and then the upload panel closes. You then try to upload following files, when the upload panel opens, it has the pathway of the old uploaded file in the location field. This can become very annoying having to manually delete it each time.What I would like to do is whenever the upload panel is opened, that the field will be empty.
I have this form that validates a few textboxes & a dropdownlist. And when it is not filled in, the border of the textboxes and dropdownlist would turn red, followed by an alert message notifying which field have not been filled in.Else, the border will revert back to black, and the form will be submitted successfully. Right now, I would like to prevent the user from entering blanks (like entering a space to cheat the system). How should I tweak the codes to make it work?
<script language = "Javascript"> function echeck(str) { var at="@" var dot="." var lat=str.indexOf(at) var lstr=str.length var ldot=str.indexOf(dot) if (str.indexOf(at)==-1){ alert("Invalid Email") return false } ..... The form submits even if no input is provided. The database get updated with blank values.
I would like to passwith the help of javascript empty non-mandatory fields to my perl script (and replace them with a custom value). The form mailer script only passes the mandatory fields. When non mandatory fields are filled , these are added to the list of passed field values, otherwise the list includes only the mandatory ones. I'd like to pass all values even the empty ones so that the person receiving the submitted data via email can easily export them to a database via a macro written by somebody else. Another requirement from client: The predefined values must not show up in the form fields when loading the page with the form.
How can I check for empty values as well as for tabs or blank spaces and replace each of these fields with a value = "not available"? I tried to do solve this for empty fields (no tabs, no blank spaces) but my solution does not work properly. It requires me to click the submit button 3 times before the form is submitted (because with every click the "not available" value is added in each empty field.
I am using a script that tabs to the next field on Enter, but it doesn't have logic to deal with hidden fields and instead stalls with "Error: Can't move focus to the control because it is invisible, not enabled, or of a type that does not accept the focus."
How would one implement a simple checking mechanism to skip focus on hidden fields and the like?
I need a JS validation code for validating numbers such that,Empty space and characters(including + and -) shouldn't be allowed,there should be only one decimal point,spaces and characters between numbers also shouldn't be permitted.
I got help with creating a method (to have only increments of 10 as valid values for certain fields in the form).
jQuery.validator.addMethod("roundnumber", function(value, element, params) { return (value % 10) == 0; }, "Your order of vaccine must be in increments of 10");
I've also found info on how to add rules to a class (there are multiple fields and name generated dynamically so I have to use class).
So I've added both these lines to additional-methods.js, but it does not validate it on submit. I do have php back-end logic that sets values to the nearest round number but I do want Js navigation before submission.
