微信小程序 定时器setInterval、setTimeout，简单易用

      setTimeout(function() {
         console.log('doSomething')
      }, 2000);

clearTimeout(timeoutID)

data: {
     color: "#ff6f10", //按钮颜色
     disabled: false, //是否可以点击
     getCode: "获取验证码", //显示文字
},

<button size="mini" type="default"  plain="true" class='form-code-btn' 
bindtap='sendCode' style='color:{{color}}; border-color: {{color}};background-color:#FFF;' 
disabled="{{disabled}}">{{getCode}}</button>

sendCode: function(e) {
     var that = this;
     var times = 0
     var i = setInterval(function() {
          times++
          if (times >= 60) {
               that.setData({
                    color: "#ff6f10",
                    disabled: false,
                    getCode: "获取验证码",
               })
               clearInterval(i)
          } else {
               that.setData({
                    getCode: "重新获取" + times + "s",
                    color: "#999",
                    disabled: true
               })
          }
     }, 1000)
}
