回复讨论(解决方案)

你这写法本来就不对。js里面按照你写的意思,是给btn绑定一个click事件。页面上,你是直接调用check()方法。
要么你把页面上调用check去掉,然后绑定
$(function(){
$("#btn").bind('click',function(){
//do somethings
});
});
要不然就是调用check,写一个check方法
function check(){
//do somethings
}

click (   是个中文括号来的。

     这个好多余

验证是否为空或者内容不符,jquery有鼠标离开事件,还有就是$(document).ready(function(){})哪去了
