javaScript

var function method(a,b){
return a+b;
}

var p=method(1,2){
alert p;
}
var e =encodeuri("发给"}
document.write(e);
var a =decodeuri(e);
document.write(a);
var i =parseint("1234")
var i=parseint("a1234") NAN
NAN和所有都false，包括NAN
typeof(NAN)=null;
if(NAN)来判断
}

javaScript中的BOM：
location

window.location.href="http://www.baidu.com";
var ele1=window.document.getElementById("div");
document.getElementByTargeName()
document.getElementByClassName()
ele1.innerHtml="修改内容"

jquery

<input type="button" value="发送异步请求" onclick="fun()">
function.fun(){
$.ajax{
url:"ajaxServlet",
method:"post",
data:{"username":"luffy","sex":"fale"}
success:function(data){
alert(data);
}
})
}

Person p=new Person("zhangsan",12);
ObjectMapper obm=new ObjectMapper();
String s=obm.writeValueAsString(p);

String s="{\"name\":\"zhangsan\",\"age\":23);
ObjectMapper obm=new ObjectMapper();
Person p=obm.readValue(s,Person.class);
system.out.println(p);
