However, you probably want to set onkeyup: false to prevent performing a synchronous callback on every key press. I can test my element for validity before enabling the rest of the form. I've tested this with my own form and it works great. Var message = response || faultMessage(element, "remote") Įrrors = ssage = $.isFunction(message) ? message(value) : message Thus, in this article, we are going to tackle mostly on the usage of Kendo UI jQuery validator. In addition, developers tend to like this subject and most newbies are excited when practicing with this. Valid = response = true || response = "true" Client-side form validation is a must-have skill regardless of years of experience as a developer.

The source code of of the remote function in v1.11.1 starts on line 1112 of : remote: function( value, element, param ) || param You can just copy the source code from the regular remote validation and modify it to handle synchronous ajax calls, and be synchronous by default. I've tried this myself, and it seems to work fine. The solution to making valid() and element() behave synchronously when using a synchronous callback is to add a custom validation method.

The internal remote function always returns "pending" which will cause the valid() function to return true even if the request is already complete and received a false response! It doesn't check the value of the response or show the error until later. So, why does setting async: false not work? If you set async to false, the request will be made synchronously, however, the plugin doesn't handle this correctly. I could just do it by hand instead of using jQuery Validation, but that's a duplication of effort.

Client side form validation also helps in providing better user interactivity with the website, while deep verification or validation of input data is being done at Server-side. checking empty input fields, identifying valid email address, verification of password constraints etc. For instance, the page I am working on needs to check the validity of a field using a remote validator before enabling the rest of the form. This type of form validation is done at browser level, i.e., handling simple constraint validations e.g.

However, there are plenty of reasons why you may need to do that. This issue only arises when you are manually checking valid() or element(). Internally, it will wait for all asynchronous requests to complete before allowing the form to be submitted. Just let the Validate plugin do it for you. In addition, there is no easy answer to this question, and the solution requires adding a custom validation method to jQuery Validation.Īctually, the easy answer may just be: Don't call valid() manually if all you want to do is submit the form. As of jQuery Validate 1.11.1 (and perhaps even older), the accepted answer does not work.
