Question

What are some ways to create a flashing effect for text in HTML and JavaScript?

Although flashing text is typically prohibited in many places, my client has requested it for a project. I need to create one line of text that flashes using HTML and JavaScript. The text should appear and disappear within seconds, repeating this cycle.

I am aware that the CSS property text-decoration:blink can achieve this effect, but unfortunately it only works in FireFox and Opera. I require the flashing text to be visible on all browsers including Firefox, Chrome, Safari, and IE. Despite my efforts, I have not been able to find a Javascript code that accomplishes this task.

If anyone knows how to make this work across all browsers, please share a working version of the code to flash the text properly.

Answer №1

var blink_delay = 1000; // every 1000 == 1 second, can be adjusted
var t = setInterval(function () {
    var element = document.getElementById('myBlinkingDiv');
    element.style.visibility = (element.style.visibility == 'hidden' ? '' : 'hidden');
}, blink_delay);

<div id="myBlinkingDiv">Hello World, the blinking effect is here!</div>

This code feels wrong.

If you want to achieve a blinking effect, you can use the following approach:

<div id="BlinkingText">Blink</div>

Here's the script that will make the text blink:

$(document).ready(function() {
    var element = document.getElementById('BlinkingText');
    setInterval(function() {
        element.style.display = (element.style.display == 'none' ? '' : 'none');
    }, 1000);

});

You can view a working example here: http://jsfiddle.net/7XRcJ/

If you prefer not to use jQuery, you can try this alternative method:

window.addEventListener("load", function() {
    var element = document.getElementById('BlinkingText');
    setInterval(function() {
        element.style.display = (element.style.display == 'none' ? '' : 'none');
    }, 1000);

}, false);

It's worth noting that different browsers may require different approaches for event handling, so using a cross-browser library is recommended for better compatibility.

An additional option is to use the onload event in the body tag. Here's a complete example tested in Firefox and IE7:

function blink() {
   var element = document.getElementById('BlinkingText');
   setInterval(function() {
      element.style.display = (element.style.display == 'none' ? '' : 'none');
   }, 1000);
}

<html>
<body onload="blink();">

<div id="BlinkingText">Blink</div>

</body>
</html>

To achieve a blinking effect using jQuery, you can utilize the following code snippet:

<div id="msg"> <strong>This will blink</strong> </div>

<script type="text/javascript" />
    function blink(selector){
        $(selector).fadeOut('slow', function(){
            $(this).fadeIn('slow', function(){
                blink(this);
            });
        });
    }
    $(function() {
        blink('#msg');
    });
</script>

Take a look at this specific code snippet.

function makeItGlow() {
  var glows = document.getElementsByClassName("glow");
  for(var i = 0, l = glows.length; i < l; i++){
    var glow = glows[i];
    var visibilityState = glow.style.visibility;
    glow.style.visibility = visibilityState == 'visible' ? 'hidden' : 'visible';
   }
 }

setInterval(makeItGlow, 500 /* interval for glowing in milliseconds */);

This method will cause all elements with the class name of glow to visibly change.

When faced with the need to accomplish this task, one option is to utilize the blink plugin designed for jQuery

$(document).ready(function() {
        $('.blink').blink(); // default is 500ms blink interval.
        //$('.blink').blink({delay:100}); // causes a 100ms blink interval.
});

If you want to add some flashiness to your website, you can use jQuery to make text blink. All you have to do is wrap the text you want to blink in a <blink> tag and include the following JavaScript code. You can adjust the duration if the blinking effect is too fast.

<script type="text/javascript">
  setInterval(function(){
      $('blink').each(function(){
        $(this).css('visibility' , $(this).css('visibility') === 'hidden' ? '' : 'hidden')
      });
    }, 250);
</script>
<blink>Your blinking text goes here</blink>

Here is an example of how you could implement a blinking effect:

<html>
<head>
    <style>
        #blink{
            color:black;opacity:1;font-size:3EM;
        }
    </style>
</head>
<body>
    <div id="blink">
        Hello
    </div>
    <script>
        var ops,blink=document.getElementById('blink');
        ops=1
        setInterval(function (){
            ops = (ops < 1) ? 1:0;
            blink.style.opacity=ops;
        },500);
    </script>
</body>

This code will make the text inside the div element with id "blink" blink on and off every 500 milliseconds.

Answer №10

CSS:

.hidden { visibility: hidden; }

JS:

setInterval(blinkFunc, 200)

blinkFunc = function () {
  var selector = '#some-selector';

  jQuery(selector + ':visible').addClass('hidden');
  jQuery(selector + ':not(:visible)').removeClass('hidden');
}

It is advisable to consider changing the color instead of using visibility due to potential browser compatibility issues with Webkit.
