JQuery fading special effect

I want to make the black text of the error message “glow” with a red outline, which disappears after a second, but if updated, returns to “full glow” and starts to disappear again, even if it was not in the first place, completely disappeared. Is there a pretty simple jQuery / CSS way to do this? I think that the two methods of simultaneous attenuation will compete with each other, be asynchronous and all, and I don’t quite know how to generate a luminous effect, or even if it is possible using the standard style.

You do not need to use any external plugins, you can only do this with jQuery 1.8 and css3 , but it is not easy. You need to combine the css3 property text-shadowwithanimate()

UPDATE: Bugs fixed.

The blue effect of jsFiddle works here.

JQuery

var red = $(".red");
red.click(function() {
   if ( !$(this).is(':animated') )

    //you just adjust here
    red.glowEffect(0,40,500);
    //which is:
    //red.glowEffect( start value , destination value , duration );
});

$.fn.glowEffect = function(start, end, duration) {
    var $this = this;
    return this.css("a", start).animate({
        a: end
    }, {
        duration: duration,
        step: function(now) {
            $this.css("text-shadow","0px 0px "+now+"px #c61a1a");
        }
    });
};​

CSS

.red { text-shadow: 0px 0px 0px #c61a1a; }

Note. No need to define provider prefixes such as -webkit- -ms- -moz- -o-jQuery 1.8 fixes this automatically.

How to combine jQuery animation with css3 properties without using css transitions?

A pure CSS3 solution stolen shamelessly from here :

a.glow, a.glow:hover, a.glow:focus {  
    text-decoration: none;  
    color: #aaf;  
    text-shadow: none;  
    -webkit-transition: 500ms linear 0s;  
    -moz-transition: 500ms linear 0s;  
    -o-transition: 500ms linear 0s;  
    transition: 500ms linear 0s;  
    outline: 0 none;  
} 
a.glow:hover, a.glow:focus  {  
    color: #fff;  
    text-shadow: -1px 1px 8px #ffc, 1px -1px 8px #fff;  
}

barlasapaydin, :

$.fn.glowEffect = function(start, end, duration, callback) {
    // Fetch last animation position
    if (this.data("last-glow")) 
        start = this.data("last-glow");

    return this.animate({
        'placeholder': end // This can be anything, it just a placeholder to allow the animation to run
    }, {
        duration:duration,
        step: function(now, fx) {
            // Calculate current position
            now = parseInt(start + (end - start)*(fx.pos));
            // Set current animation position
            $(fx.elem).css("text-shadow","0px 0px "+now+"px #c61a1a")
                // Save position (if animation is interrupted)
                .data("last-glow", now);
        },
        complete:callback
    });
};

$(".red").click(function() {
    $(this)
        .stop()
        .glowEffect(0,50,1000, // Fade in
                    function() 
                    { 
                        $(this).glowEffect(50,0,1000);  // Fade out
                    });
});

text-shadow CSS3 $( ". textid" ). stop(). addClass ( "glow", 1000); .

JQuery, - :

JQuery fades with loop and delay

You can then use CSS3 to add a glow to the text (or shadow), but note that this is not supported in some browsers.
