alternative to blink() method

I am in a need of having a blinking function in my application. Basically, I am creating a calculator and I need something like "|" to blink after the user inputs each numbers from the button. For firefox and opera, something like:

var str = "Hello world!";
document.write(str.blink());

This is exactly what I want. My problem is they don't work in Chrome, IE or safari. Is there any easy substitution for this or I have to create blinking functionality myself if I want my application to run on cross-browsers?

Try this-:SOLUTION NO 1

You can create your own custom blink function.This can also be done by creating css class and adding them to our element.

function blink()
    {
        setInterval(function () {
            document.getElementById("blink").style.webkitTransitionDuration = "0.7s";
            document.getElementById("blink").style.opacity = 0;
            setTimeout(function () {
                document.getElementById("blink").style.webkitTransitionDuration = "0.7s";
                document.getElementById("blink").style.opacity = 1;
            }, 700);
        },1400);

    }

OR

try this-->SOLUTION NO.2

JAVASCRIPT

function blink()
        {       
document.getElementById('blink').className = "animated blink_css";
        }

In css

.animated {
    -webkit-animation-fill-mode:both;
    -moz-animation-fill-mode:both;
    -ms-animation-fill-mode:both;
    -o-animation-fill-mode:both;
    animation-fill-mode:both;
    -webkit-animation-duration:1s;
    -moz-animation-duration:1s;
    -ms-animation-duration:1s;
    -o-animation-duration:1s;
    animation-duration:1s;
}

  @keyframes 'blink' {
   0% { background: rgba(255,0,0,0.5); }
   50% { background: rgba(255,0,0,0); }
   100% { background: rgba(255,0,0,0.5); 
}
//try moz for mozilla,o for opera and webkit for safari and chrome 
    .blink_css {
        -webkit-animation-name: blink;
        -moz-animation-name: blink;
        -o-animation-name: blink;
        animation-name: blink;
    }

Both of them will work.Tested!!!

If you truly want cross-browser compatibility, you should use a library, jQuery for instance.

Here is a nice little script that accomplishes what you want- http://www.silverphp.com/simple-jquery-blink-script-alternative-to-html-blink-tag.html

On the other hand, if you prefer vanilla JS, you may have to implement it yourself. Maybe use setInterval() with a function that makes the element disappear?

you could use just css3 :

@keyframes 'blink' {
   0% { background: rgba(255,0,0,0.5); }
   50% { background: rgba(255,0,0,0); }
   100% { background: rgba(255,0,0,0.5); }
}
