Thinkphp 边学边用-验证码无意间犯的错

1 $(".verify_img").click(function(){
2         var timenow = new Date().getTime();
3         var url ="{:U(‘index/loginverify‘)}&t="+timenow;
4         alert(url);
5         $(this).attr("src",url)
6     });

 $(".reloadverify").click(function(){
     var timenow = new Date().getTime();
        var url ="{:U(‘index/loginVerify‘)}?t="+timenow;
       $("#image_d").attr("src",url) 
    });
