使用prototype
[javascript]
var str = [“a”,”b”];Array.prototype.f=function(){}
for(var key in str){
console.log(key + “::” + (str[key] + “”));
}
// 0::a VM349:4
// 1::b VM349:4
// f::function (){}
[/javascript]
遍历数组
[javascript]
for(var key in str){
console.log(key + “::” + (str[key] + “”));
}
for(var key=0;key<str.lengh;key++){
console.log(key + “::” + (str[key] + “”));
}
[/javascript]
