jqueryCountdownShort message

This article will focus on the following functions:

1. When you click the button, you can count down and customize the countdown. 2. When receiving the text message fails, the countdown stops and you can click to resend the text message. .3. The clicked element supports general tags and input tags. Although it seems very complicated, the implementation code is actually very simple. Let me share the implementation code with you. Friends who need it can refer to it.

The main functions implemented are as follows:

1. When you click the button, you can count down and customize the countdown.

2. When receiving the text message fails, the countdown stops and you can click to resend the text message.

3. The clicked element supports general tags and input tags.

html code:


<input type="button" class="sameBtn btnCur" value="发送验证码"/>
<p class="sameBtn btnCur2">发送验证码</p>

css code:


body{padding:100px;text-align: center;}
.sameBtn{display: inline-block;font-size:12px;cursor:pointer;width:76px;height:25px;line-height: 25px;text-align: center;border:0;background: #3186df;color:#fff;}
.sameBtn.current{background: #b1b1b1;}

js code:


//短信倒计时功能
/**使用方式如下:
 * $(".btnCur").CountDownF({
 *    time:120,
 *     resetWords:&#39;重新发送&#39;, //文字定义 
 *    cnSeconds:&#39;s&#39;,//倒计时中显示中文的秒,还是s
 *    clickClass:&#39;current&#39;, //点击后添加的class类
 *    countState:true,
 *    callback:function(){
 *      setTimeout(function(){
 *       //当发送失败后,可以立即清除倒计时与其状态
 *        $(".btnCur").CountDownF(&#39;clearState&#39;);
 *      },3000);
 *    }
 *  });
 * 
 * */
