方法一:(setInterval)
$("#getCode").on("click", getCodeClick);
function getCodeClick() {
 $("#getCode").off("click");
 try {
    new common.ajaxRequest({
      url: url+"cmbntUser/getChangePhoneAuthCode?mobilePhone="+ $("#txtMobile").val().trim(),
      type: "POST",
      param: '',
      dataType: "json",
      header: header,
      callBack: function (result) {
        if(result.type =="SUCCESS"){
          var lefttime = 60;
          $("#getCode").attr("disabled", "disabled");
          $("#getCode").html("60秒后重新获取");
          var countDown = setInterval(function () {
            lefttime--;
            $("#getCode").html(lefttime + "秒后重新获取");
             if (0 == lefttime) {
               $("#getCode").html("重新获取");
               $("#getCode").removeAttr("disabled");
               $("#getCode").on("click", getCodeClick);
              clearInterval(countDown);
             }
          }, 1000);
         }else{
           $("#getCode").on("click", getCodeClick);
               }
      }
   });
 }
  catch (ex) {
     $("#ErrMessage").html("发送短信失败,请稍后再试。");
    $("#ErrMessage").attr("class", "tip textred");
  }
  return false;
}

方法二:(setTimeout)

function setTime(time){
    time --;
    $('#msgCodeBtn').attr('disabled',true).html(time+'秒后重新获取');
    var timeT = setTimeout(function(){
        setTime(time)
},
1000); if(time == 0){ $('#msgCodeBtn').removeAttr('disabled').html('重新获取'); clearTimeout(timeT); } } //发送验证码 $('#msgCodeBtn').on('click',function(){ var time = 60; $('#msgCodeBtn').html('60秒后重新获取'); setTime(time); });
