Text blinking jQuery

Question

What is an easy way to make text blinking in jQuery and a way to stop it? Must work for IE, FF and Chrome. Thanks

Answer 1

I feel the following is of greater clarity and customization than other answers.

    var element_to_blink=$('#id_of_element_to_blink');
    var min_opacity=0.2;
    var max_opacity=1.0;
    var blink_duration=2000;
    var blink_quantity=10;
    var current_blink_number=0;

    while(current_blink_number<blink_quantity){
        element_to_blink.animate({opacity:min_opacity},(blink_duration/2),"linear");
        element_to_blink.animate({opacity:max_opacity},(blink_duration/2),"linear");
        current_blink_number+=1;
        }

Answer 2

This is what ended up working best for me. I used jQuery fadeTo because this is on WordPress, which already links jQuery in. Otherwise, I probably would have opted for something with pure JavaScript before adding another http request for a plugin.

$(document).ready(function() {
    // One "blink" takes 1.5s
    setInterval(function(){
        // Immediately fade to opacity: 0 in 0ms
        $(".cursor").fadeTo( 0, 0);
        // Wait .75sec then fade to opacity: 1 in 0ms
        setTimeout(function(){
            $(".cursor").fadeTo( 0, 1);
        }, 750);
    }, 1500);
});

Answer 3

Try using this blink plugin

For Example

$('.blink').blink(); // default is 500ms blink interval.
//$('.blink').blink(100); // causes a 100ms blink interval.

It is also a very simple plugin, and you could probably extend it to stop the animation and start it on demand.

Answer 4

Seeing the number of views on this question, and the lack of answers that cover both blinking and stopping it, here goes: try jQuery.blinker out (demo).

HTML:

<p>Hello there!</p>

JavaScript:

var p = $("p");

p.blinker();

p.bind({
    // pause blinking on mouseenter
    mouseenter: function(){
        $(this).data("blinker").pause();
    },
    // resume blinking on mouseleave
    mouseleave: function(){
        $(this).data("blinker").blinkagain();
    }
});

Answer 5

here's blinking with animation:

$(".blink").animate({opacity:0},200,"linear",function(){
  $(this).animate({opacity:1},200);
});

just give a blink class whatever u want to blink:

<div class="someclass blink">some text</div>

features:

• doesn't need any plugins (but JQuery itself)
• does the thing

Here you can find a jQuery blink plugin with its quick demo.

Basic blinking (unlimited blinking, blink period ~1 sec):

$('selector').blink();

On a more advanced usage, you can override any of the settings:

$('selector').blink({
    maxBlinks: 60, 
    blinkPeriod: 1000,   // in milliseconds
    onBlink: function(){}, 
    onMaxBlinks: function(){}
});

There you can specify the max number of blinks as well as have access to a couple of callbacks: onBlink and onMaxBlinks that are pretty self explanatory.

Works in IE 7 & 8, Chrome, Firefox, Safari and probably in IE 6 and Opera (although haven't tested on them).

(In full disclosure: I'm am the creator of this previous one. We had the legitimate need to use it at work [I know we all like to say this :-)] for an alarm within a system and I thought of sharing only for use on a legitimate need ;-)).
