定时器

这里提供一个表单提交的定时器，表单提交后30s内不能再次提交

提交按钮提供属性data-isSubmit

if($(".btn-pay-confirm").attr("data-isSubmit")=="true"){
　　return false;
}

var code_t;
{//按钮锁定
    var time=30;
      $(e.target).css("background","#ccc").text("订单提交中("+time+"s)").attr("data-isSubmit","true");
       code_t = setInterval(function () {
           time--;
           $(e.target).text("订单提交中("+time+"s)");
           if (time < 1) {
               clearInterval(code_t);
               $(e.target).css("background","#00b38f").text("确认付款").attr("data-isSubmit","false");
           }
       }, 1000);
}
