JavaScript中“过于”犀利地for/in循环使用示例

复制代码 代码如下:

for (String str : list) {
System.out.println(str);//其中str直接就是集合中的元素
}

复制代码 代码如下:

var car
var garage= new Array()
garage[0] = "宝马"
garage[1] = "奔驰"
garage[2] = "宾利"
for (car in garage)
{
document.write(garage[car] + " ")
}
//输出结果： 宝马 奔驰 宾利

复制代码 代码如下:

var car
var garage= new Array()
garage[0] = "宝马"
garage[1] = "奔驰"
garage[2] = "宾利"
garage.locked = true
garage.clean = function(){
alert("清洁")
}
for (car in garage)
{
document.write(garage[car] + " ")
}
//输出结果：宝马 奔驰 宾利 true function (){ alert("清洁") }

复制代码 代码如下:

var car
var garage= new Array()
garage[0] = "宝马"
garage[1] = "奔驰"
garage[2] = "宾利"
garage.locked = true
garage.clean = function(){
alert("清洁")
}
for (car = 0;car < garage.length;car++)
{
document.write(garage[car] + " ")
}
//输出结果：宝马 奔驰 宾利
