.substring error: “is not a function”
var currentLocation = document.location, muzLoc = currentLocation.substring(0,45), 这时候如果执行，总是无法输出muzLoc ,因为本来这个语法就出错了，document.location是一个对象，把一个对象当作字符串肯定是出错的 应该先currentLocation.toString()然后再用截取字符串

Objective-C中小怪兽的逻辑
defense; 1.为了小怪兽的移动打基础，必须有个方法能够更新位置，也就是实现如果小怪兽要移动，那么必须有新的坐标产生，这个新的坐标就是小怪兽要移动的位置，移动时把原有的坐标更新成现在小怪兽在的地方，而currentLocation - (void) setCurrentLocation:(Location *)vCurrentLocation 3 { 4 //位置更新 5 originalLocation = currentLocation ; 6 currentLocation = vCurrentLocation; 7 } 2.小怪兽类要想快速的复制更多的小怪兽，必须得有便利初始化方法和便利构造函数，代码如下 1 //便利初始化方法 getLocationX]; 10 int oY = [originalLocation getLocationY]; 11 12 //获取现在的位置 13 int cX = [currentLocation getLocationX]; 14 int cY = [currentLocation getLocationY]; 15 16 //获取现在位置的坐标 17 NSLog
