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

Text Blinking start and stop on button click -

<input type="button" id="btnclick" value="click" />
var intervalA;
        var intervalB;

        $(document).ready(function () {

            $('#btnclick').click(function () {
                blinkFont();

                setTimeout(function () {
                    clearInterval(intervalA);
                    clearInterval(intervalB);
                }, 5000);
            });
        });

        function blinkFont() {
            document.getElementById("blink").style.color = "red"
            document.getElementById("blink").style.background = "black"
            intervalA = setTimeout("blinkFont()", 500);
        }

        function setblinkFont() {
            document.getElementById("blink").style.color = "black"
            document.getElementById("blink").style.background = "red"
            intervalB = setTimeout("blinkFont()", 500);
        }

    </script>

    <div id="blink" class="live-chat">
        <span>This is blinking text and background</span>
    </div>

If you'd rather not use jQuery, this can be achieved with CSS3

@-webkit-keyframes blink {  
  from { opacity: 1.0; }
  to { opacity: 0.0; }
}

blink {
  -webkit-animation-name: blink;  
  -webkit-animation-iteration-count: infinite;  
  -webkit-animation-timing-function: cubic-bezier(1.0,0,0,1.0);
  -webkit-animation-duration: 1s; 
}

Seems to work in Chrome, though I thought I heard a slight sobbing noise.

Combine the codes above, I think this is a good solution.

function blink(selector){
    $(selector).animate({opacity:0}, 50, "linear", function(){
        $(this).delay(800);
        $(this).animate({opacity:1}, 50, function(){
        blink(this);
        });
        $(this).delay(800);
    });
}

At least it works on my web. http://140.138.168.123/2y78%202782

You can also try these:

<div>some <span class="blink">text</span> are <span class="blink">blinking</span></div>
<button onclick="startBlink()">blink</button>
<button onclick="stopBlink()">no blink</button>

<script>
  function startBlink(){
    window.blinker = setInterval(function(){
        if(window.blink){
           $('.blink').css('color','blue');
           window.blink=false;
         }
        else{
            $('.blink').css('color','white');
            window.blink = true;
        }
    },500);
  }

  function stopBlink(){
    if(window.blinker) clearInterval(window.blinker);
  } 
</script>

I like alex's answer, so this is a bit of an extension of that without an interval (since you would need to clear that interval eventually and know when you want a button to stop blinking. This is a solution where you pass in the jquery element, the ms you want for the blinking offset and the number of times you want the element to blink:

function blink ($element, ms, times) {
    for (var i = 0; i < times; i++) {
        window.setTimeout(function () {
            if ($element.is(':visible')) {
                $element.hide();
            } else {
                $element.show();
            }
        }, ms * (times + 1));
    }
}
