Thinkphp Learn and Use - Unintentional Mistakes in Verification Code_PHP Tutorial

Thinkphp learning and using at the same time - Verification code unintentional mistakes

Look at the code first:

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 });

Look at the following code again:

$(".reloadverify").click(function(){

var timenow = new Date().getTime();

var url="{:U('index/loginVerify')}?t="+timenow;

$("#image_d").attr("src",url)

});

What is the area of ​​the above code? The difference between &. After comparison, you can see where the problem lies. It is also valid to directly follow a random number after the question mark. var url="{:U('index/loginVerify')}?"+Math.random();

The problem is already very clear when I write this.
