Highlight A Specific DIV Depending On URL

I have a list of FAQs on, say, page faq.html like so:

...

...

I now want to pulsate or simply highlight one of th

Solution 1:

If you can ad a fragment to the URL you can use the CSS :target pseudo-class.

HTML:

<a href="#see" id="see">See</a> <a href="#works" id="works">works</a> <a href="#well" id="well">well</a>​

CSS:

a:target{
    transition:background-color 1s ease-in;
    -webkit-transition:background-color 1s ease-in;
    -moz-transition:background-color 1s ease-in;
    background-color: yellow;
}​

Solution 2:

for highlighting it you can do this

var Blinkcnt = 0;
function BlinkDiv(DivId) {
    if (Blinkcnt % 2 == 0) {
        $('#' + DivId).animate({ backgroundColor: "#E1E1E1" }, 500);
        Blinkcnt += 1;
    }
    else {
        $('#' + DivId).animate({ backgroundColor: "#F8F8F8" }, 500);
        Blinkcnt += 1;
    }
    if (Blinkcnt < 10) {
        setTimeout(function () {
            BlinkDiv();
        }, 500);
    }
    else {
        Blinkcnt = 0;
        $('#' + DivId).animate({ backgroundColor: "#F8F8F8" }, 500);
    }
}

Solution 3:

You can use this using the CSS :target selector (so to target faq2 only when the fragment is #faq2, use faq2:target { ... } ).

Also to animate it, look into CSS3 transitions and keyframes.

Solution 4:

$(function() {
    var params = window.location.href.split('?')[1].trim().split('&');
    var location = '';

    for( var i=0; i<params.length; i++ ) {
        var pair = params[i].split('=');
        location = pair[0] ==='highlight' ? pair[1] : '';
    }

    if ( location ) {
        $('#'+location).effect("highlight", {}, 3000);
        // or $('#'+location).effect("pulsate", { times:3 }, 2000);
    }
});
