how to pass this element to javascript onclick function and add a class to that clicked element

I had an html navigation code as below

function Data(string) {
  //1. get some data from server according to month year etc.,
  //2. unactive all the remaining li's and make the current clicked element active by adding "active" class to the element
  $('.filter').removeClass('active');
  $(this).addClass('active');
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="row" style="padding-left:21px;">
  <ul class="nav nav-tabs" style="padding-left:40px;">
    <li class="active filter"><a href="#month" onclick="Data('month')">This Month</a></li>
    <li class="filter"><a href="#year" onclick="Data('year')">Year</a></li>
    <li class="filter"><a href="#last60" onclick="Data('last60')">60 Days</a></li>
    <li class="filter"><a href="#last90" onclick="Data('last90')">90 Days</a></li>
  </ul>
</div>

When the user clicks on any of the tabs

• all the remaining tabs should be unactive,
• and the current element/tab should be active,

My code above is not working.

1. How to make the above code work?
2. I only want to use javascript onclick for this. Is there any way that the this(current) object is send when the user clicks on the tab?

Solution 1:

Use this html to get the clicked element:

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

Script:

 function Data(string, el)
 {
     $('.filter').removeClass('active');
     $(el).parent().addClass('active');
 } 

Solution 2:

You can use addEventListener to pass this to a JavaScript function.

HTML

<button id="button">Year</button>

JavaScript

(function () {
    var btn = document.getElementById('button');
    btn.addEventListener('click', function () {
        Date('#year');
    }, false);
})();

 function Data(string)
          {
                $('.filter').removeClass('active');
                $(this).parent().addClass('active') ;
          }
