JQuery adding a class

Question

I want add a class when a <li> element clicked. but it didn't work. Here's JQuery snippet

$(".mama").click(function(){        
    var arr = ["cat","dog", "mice", "bird"];
    alink =  $(this).text();        

    $.each(arr, function(index, value) {
        if(alink == value){
            $(this).addClass('hi'); 
        }
    }); 
});

And HTML

<ul id="animal">
    <li class="mama"><a href="#">cat</a></li>
    <li class="mama"><a href="#">dog</a></li>
    <li class="mama"><a href="#">Mice</a></li>
</ul>

i also have tried to do it by .map but nothing happen. please give solution and some explain. Thanks

Answer 1

This should work:

$(".mama").click(function(){   
    var $this = $(this);     
    var arr = ["cat","dog", "mice", "bird"];
    alink =  $(this).text();        

    $.each(arr, function(index, value) {
        if(alink == value){
            $this.addClass('hi'); 
        }
    }); 
});

because this inside the each is not the DOM element <li>.

Answer 2

You probably just need to do this:

http://jsfiddle.net/reugB/1/

$('.mama').on('click', function(evt) {
    evt.preventDefault();
    $(this).addClass('hi');
});

Answer 3

Use this to refer to current element which was clicked.

$(".mama").click(function (e) {
    e.preventDefault();
    $(this).addClass('hi');
});

Answer 4

If you mean add the class hi to the clicked li, just do like below:

$(".mama").click(function(e){
    e.preventDefault();
    $(".mama").removeClass('hi');
    $(this).addClass('hi')        
});

Answer 5

 .hi { background-color: #f00 !important;}


 $('.mama').on('click', function(evt) {
evt.preventDefault();
$(this).addClass('hi');

});

Answer 6

$(".mama").click(function(e){    
e.preventDefault();    
    var arr = ["cat","dog", "mice", "bird"];
    var alink =  $(this).find("a").text();        

    $.each(arr, function(index, value) {
        if(alink == value){
            $(this).addClass('hi'); 
        }
    }); 
});
