//多个输入框问题
$("input,textarea").on("blur",function(){setTimeout(function(){window.scrollTo(0,0);},100)
}).on('focus',function(){var clientHeight = document.documentElement.clientHeight || document.body.clientHeight;var offsetTop = $(this).offset().top - (clientHeight / 4);setTimeout(function(){window.scrollTo(0,offsetTop);},100)
})
