ie not applying invalid psuedo class on checkValidity or exiting form field

1DMF · Jun 19, 2014

Hi,

I have some css

Code:

:required:valid + span.tickcross::after { content: '\f058'; }
:required:invalid + span.tickcross::after { content: '\f057'; } 
:required:valid + span.tickcross {color:green;}
:required:invalid + span.tickcross {color:red;}

Which is working fine in FF as I fill the form in, I get my green ticks as desired.

As you populate a field, it seems FF re-validates the form and applies the valid pseudo class when you exit the field.. all is good

.

However, in IE if I enter valid input and leave the field the form isn't revalidated and the invalid pseudo class is still showing a red cross.

So I added some on-blur events...

Code:

    // ensure form is revalidated when field is exited
    $('[required]').on('blur',function(){ $('form')[0].checkValidity();});

However, even though this event is firing when I exit the input field, still the incorrect pseudo classes aren't being applied in IE.

If I just click on any blank part of the page, outside of another input field, then the correct pseudo class 'content' shows.

Why can't I get IE to correctly re-apply the pseudo classes and update the screen using .checkValidity() ?

Thanks,

I've given up with the pseudo classes for form validation in IE, they simply don't get applied correctly.

Don't know if it's a browser refresh issue or what, but CSS3 form validation pseudo classes work exactly as desired in FF but IE11 is very flaky.

In the end I went with a JQuery solution with my own classes bolted on to the ':required' pseudo class.

CSS

Code:

/* form validation pseudo classes */
span.tickcross  {
    width:15px;
    height:15px;
    display:inline-block;
    margin-top:5px;
    float:right;
    font-family: 'FontAwesome';   
   }
   
:focus:required:invalid {
    background-color:pink;
    opacity:.6;
    }
    
:invalid, .invalid {
    box-shadow: none !important;  
    -moz-box-shadow: none !important;
    outline:none !important;
}
        
/* form validation awesomeness for pseudo class */
:required + span.tickcross::after { content: '\f071'; }
:required + span.tickcross {color:orange;}

:required.invalid + span.tickcross::after { content: '\f057'; }
:required.invalid + span.tickcross {color:red;} 

:required.valid + span.tickcross::after { content: '\f058'; }
:required.valid + span.tickcross {color:green;}

JQuery / JS

Code:

    // handle required fields as IE pseudo classes don't work properly
    $('[required]').on('blur',function(){ checkValid(this);});
    $('[required]').on('focus',function(){ checkValid(this);});
    $('[required]').on('keyup',function(){ checkValid(this);});
    $('[required]').on('keydown',function(){ checkValid(this);});    
    $('[required]').on('change',function(){ checkValid(this);});    
    $('select').on('click',function(){ checkValid(this);});            
    $('[required]').on('invalid',function(){ $(this).addClass('invalid'); });

    function checkValid(ele)
    {
        if(ele.validity.valid)
        {   
            $(ele).removeClass('invalid'); 
            $(ele).addClass('valid'); 
        }
        else
        { 
            $(ele).removeClass('valid'); 
            $(ele).addClass('invalid');        
        }    
    }

Not ideal but at least IE is correctly applying the right validation classes and toggling my special chars as desired.

Incidentally, I have used empty spans as content in my actual HTML mark-up...

Code:

<label for="url">URL Address</label>
<input placeholder="Please enter full URL of website" type="url" name="URL" id="url" value="<tmpl_var name='URL'>" maxlength="250" />
[b]<span class="tickcross"></span>
[/b]

Is having empty tags as physical content in your mark-up considered good practice?

Should I be dynamically inserting the span's with JS/JQ?

Seeing's as I am using them more for design, and as you can't insert HTML with pseudo elements, what's the best way I should be doing this?

Or are the span's perfectly acceptable?

I'm thinking of adding a 'title' attribute to each span to use for tooltip form fill out guidance, would the spans then be considered content?

You input is appreciated.
