Trigger click not woking in safari

this is my jquery script

<script type="text/javascript">
var spConfig = new Product.Config(<?php echo $this->getJsonConfig() ?>);
        jQuery("#amconf-images-150").css("display","");
        function select_dd_watts(div_id)
        {
            var volage_btn = div_id;       
            div_id = div_id.split("-");
            var attr_id = div_id[1];
             jQuery(".watts-text").css("color","#fff");
             jQuery(".watt-class").css("color","#fff");
             jQuery(".watts-div").css("background","#000");
             jQuery("#"+volage_btn).css("background","#602021");
            jQuery("#amconf-image-"+attr_id).trigger("click");
        }
 </script>
       
This is my code of phtml file of magento

<div class="watts-div" onclick="select_dd_watts(this.id)" id="watt-<?php echo $labels['id'];?>"><span class="watts-text"><?php echo $labels['label'];?></span><span class="watt-class">WATT</span></div>
