在加载页面时不要显示js内容

Question

我遇到了以下问题：我有一个简单的javascript - section，（.custom-social-proof）具有不同的内容加载和旋转。除了片刻之外，一切都很好 - 通常，在页面完全加载之前，我会看到所有元素。我究竟做错了什么？我对javascript很新，所以我非常感谢能找到一些帮助。

(function(jQuery){
    jQuery.fn.extend({ 
        rotaterator: function(options) {
 
            var defaults = {
                fadeSpeed: 900,
                pauseSpeed: 9000,
				        child:null
            };
             
            var options = jQuery.extend(defaults, options);
         
            return this.each(function() {
                  var o =options;
                  var obj = jQuery(this);                
                  var items = jQuery(obj.children(), obj);
				  items.each(function() {jQuery(this).hide();})
				  if(!o.child){var next = jQuery(obj).children(':first');
				  }else{var next = o.child;
				  }
				  jQuery(next).slideToggle(o.fadeSpeed, function() {
						jQuery(next).delay(o.pauseSpeed).slideToggle(o.fadeSpeed, function() {
              
							var next = jQuery(this).next();
							if (next.length == 0){
									next = jQuery(obj).children(':first');
							}
              
              setTimeout(function() {
							jQuery(obj).rotaterator({child : next, fadeSpeed : o.fadeSpeed, pauseSpeed : o.pauseSpeed});
              }, 9000); // pause between slides
						})
					});
            });
        }
    });
})(jQuery);

 });

Answer 1

您可以默认隐藏父类，然后在隐藏子项后显示它。

<div id="all-social-proofs" style="display:none"> 
  ...

和

 jQuery(document).ready(function() {
        jQuery('#all-social-proofs').rotaterator();
        jQuery('#all-social-proofs').show();
 });
