How to stop an anchor from redirecting using JQuery

Question

How can I stop an anchor tag redirecting to another page if the user is not logged in? I have a function to check if the user is logged in or not. I want to do it with JQuery or JavaScript. Here is what I have tried so far but with no results:

<a href="www.somewhere.com" id="yes">Read More</a>

<script type="text/javascript">
    $(document).ready(function(){
        $('a').click(function(){
            var id = $(this).attr('id');
            if(id == 'yes'){
                //i want to prevent
            }else{
                //redirect
            }
        });
    });
</script>

Answer 1

Please use http://api.jquery.com/event.preventDefault/

demo http://jsfiddle.net/aRBY4/6/

e.preventDefault() 

quote

If this method is called, the default action of the event will not be triggered.

Also if I may suggest read this: .prop() vs .attr()

Hope this helps,

sample code

  $('a').click(function(event){
    event.preventDefault();
    //do whatever
  });

In your case please try this

$(document).ready(function() {
    $('a').click(function(event) {
        var id = $(this).attr('id');
        if (id == 'yes') {
            event.preventDefault();
            //i want to prevent
        } else {
            //redirect
        }
    });
});​

Change your click event handler to this

$('a').click(function(e){
    var id = $(this).attr('id');
    if (id == 'yes')
    {
        e.preventDefault();
        e.stopPropagation();
    }
    else
    {
        //redirect
    }
});

try this one

    $("a").on("click",function(e){
         e.preventDefault();
         alert("Clicked");

     });

happy Coding;

Use event.preventDefault(). It is used to prevent the default action of the event.

<script type="text/javascript">
$(document).ready(function(){
      $('a').click(function(){
          var id = $(this).attr('id');
         if(id == 'yes'){
             event.preventDefault() 
         }else{
            //redirect
         }
     });
});
</script>
