将onClick事件触发到特定的div

Question

I have two cards and I am firing an onClick() event to create a dimmer on top of the card image if a user clicks on Like button (heart icon). I am trying to create the dimmer on the card image in which user clicked the heart icon.

I tried placing a condition :

if (e.target !== this)
    return;

But it did not work. In real webpage, I will have a long list of cards with no identifier where I can specify the image to be dimmed. Is it possible in this scenario?

JSFiddle

Answer 1

Updated fiddle .

You should use the current clicked jQuery object $(this) instead to target the related .imglove in the same .card :

$(this).closest('.card').find('.imglove').dimmer('show');

NOTE : The .closest('.card') is used to get the related card with clicked icon loveit .

Hope this helps.

 $(function() { $(document).on('click', '.loveit', function(e) { e.preventDefault(); $(this).closest('.card').find('.imglove').dimmer('show'); }); });

So you're trying to limit your interaction to the currently selected image? Also, rather than reference a fiddle, post your working (or non-working) code here. Easier all around.

 jQuery(document).ready(function($) { $(document).on('click', '.loveit', function(e) { e.preventDefault(); $(this).parents(".card").find('.imglove') .dimmer('show'); }); });

Target it parent with class card then find class imglove and add dimmer to it

 jQuery(document).ready(function($) {
   $(document).on('click', '.loveit', function(e) {
     $(this).parents('.card').find('.imglove').dimmer('show');
    });
 });
