To pass this element to JavaScript onclick function and add a class to that clicked element, we can set the onclick attribute to a function that’s called with this.

For instance, we write

<div class="row" style="padding-left: 21px"> <ul class="nav nav-tabs" style="padding-left: 40px"> <li class="active filter"> <a href="#month" onclick="onClick(this)">This Month</a> </li> <li class="filter"><a href="#year" onclick="onClick(this)">Year</a></li> <li class="filter"> <a href="#last60" onclick="onClick(this)">60 Days</a> </li> <li class="filter"> <a href="#last90" onclick="onClick(this)">90 Days</a> </li> </ul> </div>

to set the onclick attribute to the a elements to call onClick with this.

Then we define the onClick function by writing

function onClick(element) { element.removeClass("active"); element.addClass("active"); }
