如果背景圖片等於特定圖片，如何向div添加類

Question

我正在嘗試將一個類添加到div（vc_gitem-animated-block），如果背景是特定的圖像。 基本上，如果我的div背景有特定的圖像（vc_gitem_image.png），我想隱藏父div。

例如，如果其他div具有不同的背景（blog-fpo.png），則我需要父div不添加類，並且不要隱藏它的父。

我的頁面中有以下代碼：

<style>
    .hide{
        display:none;
    }
    .show{
        display:block;
    }
</style>

<div class="vc_gitem-animated-block">
<div class="vc_gitem-zone vc_gitem-zone-a vc_gitem-is-link" style="background-image: url('http://savagebrands17.wpengine.com/wp-content/uploads/2016/12/blog-fpo.jpg') !important;">

    <img src="https://savagebrands17.wpengine.com/wp-content/uploads/2016/12/blog-fpo.jpg" class="vc_gitem-zone-img" alt="">
<div class="vc_gitem-zone-mini">
</div>
</div>
</div>

<p>&nbsp;</p>


<div class="vc_gitem-animated-block">
<div class="vc_gitem-zone vc_gitem-zone-a vc_gitem-is-link" style="background-image: url('https://savagebrands17.wpengine.com/wp-content/plugins/js_composer/assets/vc/vc_gitem_image.png') !important;">
    <a href="http://savagebrands17.wpengine.com/celebrating-client-work-savage-brands-honored-with-iabc-bronze-quill-awards-2/" title="Celebrating Client Work! Savage Brands Honored with IABC Bronze Quill Awards" class="vc_gitem-link vc-zone-link"></a>
    <img src="https://savagebrands17.wpengine.com/wp-content/plugins/js_composer/assets/vc/vc_gitem_image.png" class="vc_gitem-zone-img" alt="">
    <div class="vc_gitem-zone-mini">
    </div>
  </div>
 </div>

這是我的腳本：

<script>
 jQuery(function(){ /* to make sure the script runs after page load */

 if (jQuery('.vc_gitem-zone.vc_gitem-zone-a.vc_gitem-is-link').css('background-image') === 'url(https://savagebrands17.wpengine.com/wp-content/plugins/js_composer/assets/vc/vc_gitem_image.png) !important;') {

 jQuery(this).find('.vc_gitem-animated-block').addClass('hide');

 }

 });//END $function

以下代碼應在隱藏父div的同時將類添加到div（vc_gitem-animated-block）。

$(function() {
  var list = $('.vc_gitem-animated-block > div');
  $(list).each( function () {
    var bg = $(this).css('background-image');
    var ck ='url("https://savagebrands17.wpengine.com/wp-content/plugins/js_composer/assets/vc/vc_gitem_image.png")';
    if(bg === ck) {
      $(this).parent().closest('div').addClass('hide');
    } else {    
      $(this).parent().closest('div').addClass('show');
    }
  });
});
