Solidity payable 方法表现

 

 

 1 pragma solidity ^0.4.4;
 2 
 3 contract Person {
 4 
 5     string public  name;
 6     uint age;
 7     uint private weight;
 8     string internal birthday;
 9     
10     function Person() {
11         name = "";
12         age = 0;
13         weight = 0;
14         birthday = "0000-00-00";
15     }
16  
17     function f0()  payable public returns(uint){
18         return address(this).balance; // 只要一调用f0,balance就改了，不需要等f0执行结束
19     }
20     
21     function f1() public returns(uint) {
22         return address(this).balance; // 调用完f0,再调f1查询合约账户余额，与f0查到的相同
23     }
