Uncaught SyntaxError：使用jquery时无效或意外的令牌

Question

我不知道我在最后一行做错了什么

<script>
       $(document).ready(function() { 
            var currentHeight = 1;
            currentHeight = $('.footer').outerHeight();
            console.log(currentHeight);
            var newPadbod = parseInt(currentHeight)+"px";
            console.log(newPadbod);
            $("body").css("padding-bottom" , newPadbod);
       });
</script>
