thinkphp中解决首次打开网页时验证码碎图和验证码不正确问题

js代码段:

<script type="text/javascript">
    $(document).ready(function(){
        $(".verifyImg").attr("src",'__CONTROLLER__/verify?'+Math.random()); //初次打开页面刷新验证码
        $(".verifyCode").click(function(){
            $(".verifyImg").attr("src",'__CONTROLLER__/verify?'+Math.random());
        });    
    });
</script>

 

html代码段:

<div class="verify">验证码&nbsp;&nbsp;&nbsp;<input type="text" name="verify" class="verifyCode" value=""/>
　　<img class="verifyImg" src="__CONTROLLER__/verify" onclick="this.src=this.src+'?'+Math.random();" />
</div>
