摘要：uniqueID=function(){if(!arguments.callee.id) arguments.callee.id=0;return arguments.callee.id++;}uniqueID();uniqueID();uniqueID();alert(uniqueID.id);uniqueID.id=0;//设置uniqueID属性id为0.alert(uniqueID.id);//0实现一个函数，使用自己的属性来存储雍久值。但在函数外部，可以重设id为0.uniqueID=(function(){var id=0;return function(){return id++ 阅读全文

摘要：//函数add和substract.function add(x,y){return x+y;}function substract(x,y){return x-y}//operate函数调用“operator”参数传入的函数，比如add\abstract。function operate(operator,operatd1,operatd2){return operator(operatd1,operatd2);}operate(add,4,5);//调用add（4,5）函数。9operate(add,operate(add,5,1),operate(substract,4,2));//8/ 阅读全文
