JQuery :: (Validation) Add Validation On A Select Box With Auto-post?
Jul 12, 2009
I have a select box with and onchange event to get the data from serever, <SELECT name="States" id="State" onchange="getData(this.value)" > Now i want to validate that if no value is selected from the above list, then it should not send the ajax request. How can i apply the Jquery validation plugin here?
I have a form with multiple fieldsets which are visible conditionally. There are three submit buttons "Abandon", "Save" and "Save & Continue". Each button should validate specific controls of the form and submit it. I tried setting "onsubmit: false" and checking for "$('#myForm').valid ()" on click of these buttons., but that validates all controls of the form.
I am trying to display validation error messages when form validation fails. Currently it does display the error messages but then disappears straight away. How can I stop the page from refreshing when validation fails? I have return false in my code when validation fails but still having same problem. Currently I have only done the validation for the full name only. The error msg is showed in:
I have a problem where if a form submission (set up to submit via AJAX) fails validation, the next time the form is submitted, it doubles the number of post requests - which is definitely not what I want to happen. I'm using the jQuery ValidationEngine plugin to submit forms and bind validation messages to my fields. This is my code below. I think my problem is that I need to unbind from the validationEngine plugin when the form fails, but I can't figure out how to do this.
I have a formdivided into 2 fieldsets (see the image) : MASTER and DETAIL. When I press Add in the DETAIL fieldset a new item is added to an array where I store temporarly the data entered trough the DETAIL inputs and finally when I press save I send both the MASTER and DETAIL (the temporary array shown in the html table) data to the server. As you may have already noticed, I need to validate both MASTER an DETAIL, but I don't want the Save button to fire the DETAIL validation or the Add link to fire the MASTER validation. I've been googling for a while and though I couldn't find exactly what I've been looking for, I found that it's possible to add/remove a class (e.g, required, number); that gave me some ideas on how to simulate validation groups and here's the code:
<script> $ ( document
Although this code allow me to stop the MASTER validation from firing when I press Add( and DETAIL validation when I click Save), I still can't manage to insert a new DETAIL if only if all of the inputs in the DETAIL fieldset are valid and, what's more I don't want the Add link to cause a form submission.
I am using the jquery validation plugin to validate a form's email address field. The validation works but with the minor exception that when trailing whitespace is entered after the email the validation fails. I'm not sure if this is because of the regexp or a missing trim.
I'm using the Validation plugin for JQuery and was wondering if there was a function to submit the form without causing it to validate the form. I have a table with a list of radio-buttons and above that is a drop down list of states. The drop down list of states is used to filter the table rows and when the selected item changes it posts-back to the server (via $("#frm").submit()). I don't want this to cause any validation to occur. Is there another function I can call besides submit(), or some other method?
I'm using the validation plugin available here and seem to be encountering trouble in IE7. The validation is not occuring and my forms submit. Not what I want.The functions below are working fine in FF3, Opera 9.0, Chrome, & Safari.I'm going to guess this is a result of some misplaced character or ...??? Maybe a second set of eyes will spot the error.
I have a form and trying to validate all fields with jquery validation plugin.Every thing is fine except the checkboxes which i create dynamically.[code]how i make a rule which check that if no check box is checked then show error message like above input fileds do.
I've put together a pretty simple competition script - it's commented out below and you can find the demo at [URL] (you'll find the code at the bottom of the page) I am using a jquery plugin to achieve the validation: [URL] The problem is only in Firefox (3.5.2) - the form submits without any validation at all, and ignores the ajax. IE8 & 7 seem to be fine. I'm not really sure why Firefox is submitting the page with Refresh but IE isn't, I've looked over and over the code and can't find the error. Firebug is only finding errors in the jQuery library itself.
I have four inputs that relate to each other and would like to right a validation that checks each against some business logic and show a single error message if validation fails. Are there any examples of how to do this? or, best practices?
I have 9 select boxes on my page containing lots of subcategories for businesses.I require the user to select an option from only 1 of the 9 selects. To make the user experience better I hide all of the select boxes with CSS and generate a dynamic select box of categories. When a category is selected from the generated dropdown, the subcategories select box which is hidden by CSS is displayed. I am trying to apply a few validation rules to both select boxes and have a few rules I need to follow:
I have the following code that validates a credit card expiration date, from 2 separate select boxes as being valid. changing this to an addMethod for the validation plug in. I have one that works as validating input from a text input, but would like to understand this method when applied to values of select boxes. Code for change function
I have a form that submits a POST request when data is submitted.
A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine.
Here is my index.jps:
Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given.
Am I correct in calling the function onclick?
The validation essentially needs to be so that:
- Student field contains a string
- Score1, Score2, Score3 and Score 4 contain a number between 0 and 100
I have a large form. One part of it is a column with selects. All drop-downs initially set to "No". The only other option is "yes". I need to make sure that at least one select is set to "yes". Any number, even all of them can be changed to "yes", but only one is required. I can easily add a rule that requires all the fields of the certain class to have certain type of value, but can't think of a way in js to only have one required. I can easily count number of "yes" values with PHP and prevent submitting on the back end, but would really like to have jquery do it first.
I have a select list #technology. Due to some back end processing it's default value is "0" (Please Select) I am trying to write a validation rule to make it required. The problem I'm having is that if you hit submit when it shows "Please Select" which has the value="0" then make a different selection it's not removing the error msg. Also if you hit submit multiple times when it is showing Please Select it just keeps adding the error msg
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
Is it possible to check an option/select box to see if it still has data in it? I'd like to be able to stop a user from updating a file IF the field they are copying from still has content in it. I.e.
BOX 1 BOX 2 1 3 4 6 2 5
So the button will display an error message (e.g. you aint sent the entire lot over)
I've tried to attempt it but my mind cannot really handle anything more than (Check kettle for water, IF water equal or less than 1 cup full, then fill kettle with water, If kettle equal to or greater than 3 then STOP).
I have a form and I have gotten all of my error checking to work except for this. I use an <select><option> list for a states dropdown. the 1st option is blank <option></option> I have not been able to successfully check for errors (no option selected) it either always gives and error using if(state==null), or never gives an error state=="" or " " this is the only dropdown on this form so I didnt notice the problem until I had gone through all the more difficult error checking, and somehow I cant get this one seemingly simple thing figured out
I have my website www.gebcn.com. If you view source you will see all that I have done, but more importantly my problem. I have the JS code at the top there and I am unable to W3C validate my HTML because of the JS. I am using XHTML strict and would like to stay using it.
The JS I have at the top is my form validation code. I am able to do any validating that I need with this "snippet" of code, I have shrank it from my library version just to use for this newsletter. Until now W3C validating was not important now for some reason it is and I am faced with this problem.
<problem> I have tried to make this "snippet" of JS code an external file but receive multiple errors with the JS calling for the FORM NAME as it is not on the same page. The form NAME=NEWSLETTER is another problem, as W3C says I am unable to use attribute "NAME" in this location. <problem> I would like to keep the JS close to how it is now as I have a library to use this JS over and over again.
I have a ColdFusion page with a select drop down list. On submit, I'm storing the value in a cfparam and trying to use jQuery to auto select that particular option. Currently I'm using :contains but this is unacceptable because it selects the last item that contains the cfparam.
$("option:contains('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected'); Is there something like this: $("option").equals('<cfoutput>#form.company_type#</cfoutput>')").attr('selected', 'selected');
I willconsider other alternatives to accomplishing my objective.
