validation

in Using jQuery • 11 years ago

I'm looking for a way to check the form's validation status without triggering errors. I need something that just says "Yeah, this form is completely valid" or "No, it's not. Im using MVC validation with JQuery validator. When a user clicks the submit button, I have a confirmation dialogue, if confirmed, I block the UI (showing a processing message) and submit the form initiating a serverside process. the problem is with clientside validation, if the user confirms submission, but leaves out required data, validation kicks in, but the ui blocker still shows. So I need a way to just check the whole form and if any part fails validation, i dont show the UI block. This code performs a validate and does a check, but the variable isValid is always true, despite validation failing. Can anyone see where im going wrong ?

$(function() {
$("#submitCancel").click(function() {
var res = confirm('Are you sure ?');
if(res==true)
{
$("#form0").validate();
var isValid = $("#form0").valid();
$.blockUI({ message: 'processing, Please wait...', css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
setTimeout($.unblockUI, 70000);
}
return res;
});

The way you have it coded now you never use the isValid variable for anything and you always block the UI. Should you do something like this:

$("#form0").validate();
var isValid = $("#form0").valid();
if (isValid) {
$.blockUI({ message: 'processing, Please wait...', css: {
...
}

yeah I realise that i havent tested the contents of isvalid, that was on purpose, I just wanted to get a value into it and check its contents in firebug. The problem is that its always true, despite several inputs being empty, so it should fail validation.

Im using MVC validation, but im a little confused as to what javascript libarary i should be using. The project Ive inherited has included MicrosoftMvcValidation.js, but I thought i should be using MicrosoftMvcJQueryValidation.js

after swapping over, my clientside validation doesnt work at all !

anyway, it just seems that var isValid = $("#form0").valid(); always return true, no matter what, so i must be doing something wrong here, but i cant figure out what

Ive modified my code slightly but it still wont work, .valid always returns true!, I must be doing something fundamentally wrong here, can anyone help me put? Heres my updated code. What js libraries should i be using with MVC2 ? If I include MicrosoftMvcJQueryValidation.js, clientside validation stops working

$(function() {
$("#submitCancel").click(function() {
var res = confirm('Are you sure ?');
return res;
});
});
$(function () {
$('#form0').submit(function () {
$(this).validate();
if($(this).valid()) {
$.blockUI({ message: 'processing, Please wait...', css: {
border: 'none',
padding: '15px',
backgroundColor: '#000',
'-webkit-border-radius': '10px',
'-moz-border-radius': '10px',
opacity: .5,
color: '#fff'
} });
setTimeout($.unblockUI, 70000);
}
});
});

I'm not familiar with the MS validation but a couple of things to check would be that you have the correct version of it included.
Do you need to assign special classes or IDs to your form elements or the form itself?
Have you been able to step into the valid() function to see what it is doing?

not sure how i would check the version, I inherited this project, the js file itself doesnt actually have a version number in it
