实现的主要功能如下:
1.点击按钮的时候,可以进行倒计时,倒计时自定义。
2.当接收短信失败后,倒计时停止,可点击重新发送短信。

功能
/**使用方式如下:
* $(".btnCur").CountDownF({
* time:120,* resetWords:'重新发送',//文字定义
* cnSeconds:'s',//倒计时中显示中文的秒,还是s
* clickClass:'current',//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('clearState');
* },3000);
* }
* });
