JQuery :: Transforming Change Function To Validator AddMethod Rule
Jul 12, 2010
I wrote this function to be a change event applied to a checkbox. Now it is apparent I need to use it as a custom validator method, so it runs when you hit "Next" to step through the form. I have all that working, I just can't get the syntax of the rule right.
Here it is as a change event:
$(
'#MKDPT'
).change(
function(){
if(
$(
'#MKDPT'
).is(
':checked'
)){
var
checked
=
false
; .....
And my attempt at a custom validation rule:
$
.
validator
.
addMethod (
"MKDPTOnly" ,
function (
value .....
I have tried several versions, but none is letting the form go to the next step (return true) if the conditions are met.
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
How to use the IF ELSE condition inside the RUle function in Jquery Validation. I am using one form for some fields are require for option 1 and some fields are require for option 2. Example for the below code I need name and address for option one and name and url for option 2. How to use the IF/Else condition for this.
I'm quite new to Jquery, so I need some sort of advice. I'm working on a webbased application with a webservice. First it was a simple html site, but later I started using Jquery. Data is inserted in some forms, this I can easily validate through the validator. Now after all the data is ok, it's send to the webservice through the C#-code. Some calculations are being made with the data and a dataset is returned. Now some errors can occur while doing the calculations. I can't get some manual error in the errorbox of the validator. Is it possible to let the validator run some c#-function so I can see if the data is correct? Or can I set a unvisible checkbox to true/false through the c#-code so the validator check this box? A problem with both is, that the validator runs when I click on the "Next"-button. After the validaton, the function starts, so if I set the checkbox to false, the validator won't even notice. Anyone knows a handy approach for this?
My workplace has a lot of people doing manual entry. I'm looking to provide some friendly automatic formatting of data as they type it. I have working code (thus far) but I want to ensure I'm doing things in a sane way (there's a surprising amount you can do insanely that still works Here's a function below that transforms a phone number - the worker enters the digits(only), the field reflects (and could also accept) the fully formatted version (e.g. (123) 456-7890 ). I'm building this towards a plugin model (ala masked input with happy
Do any of you know if you can convert a JSON object into a Jquery object ? The reason i wish to do that is to be able to use the jquery selector to filter my Json data. (for example filter them based on their properties)
I've written my own custom validation method using addMethod which works great. But what I'd like to do is change the error message depending on which part of the validation it fails on.
I've tried defining & using a var for the message but the message never changes, a very simple cut-down example:
var customError = ""; $.validator.addMethod("myvalidator", function(value, element) {
I have created a php filter for a form that returns an error message if someone uses profanity in the comments field and makes them redo that field before inserting into a database. Here is the code I use for that (I have omitted the lengthy list of profanity..):
Code: if (isset($_POST['comments'])){ $comments = $_POST['comments']; $filter=array("badword1", "badword2"); for ($i = 0; $i < count($filter); $i++) { ..... if (preg_match("/".$filter[$i]."/i", $comments)) { $profanity_msg="Profanity is not allowed"; }}} //Then this before the form if(isset($profanity_msg)){ echo $profanity_msg; }
However, the rest of my form is validated through JQuery Validator and I would like to make a rule that would do the filtering instead of relying on the php. Here is a sketch of what I think I will need to do to build the custom rule, but I am not sure how to write the equivalent function to my php code above.
Code: $(document).ready(function(){ //custom validation rule - profanity $.validator.addMethod("profanity", "Equivalent of my php function goes here..." ); //validation implementation will go here. $("#TestForm").validate({ rules: { comments: { required: true, profanity: true }}, messages: { comments: { required: "* Required", profanity: "* No Profanity Allowed" }}}); })
If I have some XHTML that I want to transform into something else through JS (say I have a list of links to images and I want to transform it into a fancy JS-based slide-show), and I do this by calling some JS code in window.onload (in an external .js file).
The page starts loading, then the list is displayed, then once the whole page has been loaded the JS is processed, and the list is then turned into the fancy JS slide-show. The problem is, it's not very nice to *first* see the list, and then see it disappear and be substituted by something else by the JS. What would be the best way to hide the list?
I don't want to hide it with CSS because it should be visible for non JS but CSS capable agents. I came up with:
I have a text input, "Pets" and a checkbox "noPetsHS"."Pets" is required except when "noPetsHS" is checked. My validation rule currently is - and does not work? Pets:{required: "#noPetsHS:checked=false", min:1}"Pets" is usually required, very few select the checkbox, but I don't want "Pets" required if they do.I can find no reference to Rules and testing for absence of check and then requiring the text input.
I have a simple jquery selector: $('[id^=total_item]') I would like to add a rule so that the upper code would match all elements that don't have 'locked' class (so that it wouldnt match those with class='locked'). How should I add this rule to the selector?
I suppose than my css file has different rules for the same element depending of the media @media print #image { clip: rect(auto, 700px, 1200px, auto);} @media screen #image {clip: rect(auto, 1024px, 700px, auto);} Can I dynamically change the css data "clip" only for the @print media ?
I'm using the jquery validate plugin. And i'm trying to add a new validation rule.
My input field has a complex name eg. name="expiry[year]". So i am selecting the field as outlined in the documentation here:[URL].. The problem, no JS errors & no validation. If i change my input name to name="expiry" it will work, but in this particular scenario this is not an option. Can anyone advise a possible solution to this issue?
I have a form and trying to validate all fields with jquery validation plugin.Every thing is fine except the checkboxes which i create dynamically.[code] how i make a rule which check that if no check box is checked then show error message like above input fileds do
I have a case where I want to create a validator that makes use ofalready defined rules.Is it possible to somehow call <pseudocode>$.validator.rules.ruleA('value',element,null)</pseudocode>?
I have added a rule to my form but I can't understand why it does not work! [URL]. This is an example page: the rules is that the check box must be checked and there must be a valid date. From firefox console I can see it returns true or false as I need but the validation does not get triggered. Why is that?
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'm trying to create a new validation rule to check if a button has a class. I try to explain the scenario. I have a button that makes an ajax call to check the availability of a product. When the app loads the button as class "to_check", when the button is clicked an ajax call is fired, a server script return the availability of the product and basing on this answer I change the class of the button from "to_check" to "ok" or "ko". Now I want to validate the button to se if the availability is being checked and is ok, then I wrote this:
Now I want to add this rule to the button with the metadata plugin inside the class name with this syntax: <pre id="line175"><span id="__firefox-tidy-id" style="background-color: rgb(221, 221, 255);"><<span class="start-tag">input</span><span class="attribute-name"> type</span>=<span class="attribute-value">"button" </span><span class="attribute-name">name</span>=<span class="attribute-value">"verifica_disponibilita" </span><span class="attribute-name"> .....
So I created a custom rule following numerous examples out on the web for a dynamic text input, but for some reason it seems to be letting spaces through even though my regexp tests out ok to not match when the value is any combination of spaces...
$.validator.addMethod("noSpace", function(value, element){ return this.optional(element) || /^[a-z0-9][a-z0-9_ ]{0,70}$/i.test(value); }, "Please enter a name starting with either a letter or a digit."); $('#form').validate({ rules: { [Code]...
The odd thing is, it will work if you type in a space followed by a character, but if you type in one space, or one space followed by x number of spaces, it just lets it through like it's valid. But yet when I look at the demos and examples that I pulled this from, they never let those scenarios go through.
I've seen tons of things for fixing it with IE6 but some of my users are getting this with IE8.I don't see too many answers to problems with this plugin is it not being supported anymore?I also see that the version on the jQuery site is 1.5.5 and the version on the author's site is 1.8.1; does this mean that the author isn't keeping things here updated and thus isn't supporting the product via these channels like he says on his site?
My client is using the following script to validate a form : -

I want to be able to validate a Postcode by matching a regular expression (using this script). There is no default option with this jQuery script to do so. My question is can I add such a custom regex to this script?
I have only ever written validation in "normal" JS before. Also I would like the JS regex to match the existing one serverside (PHP):
