在JavaScript中，常用Array来存储和 *** 作对象:
Array:
新建:var ary = new Array()或 var ary = []
增加:ary.push(value)
删除:delete ary[n]
遍历:for ( var i=0 i <ary.length ++i ) ary[i]
// 合并对象function extend(target, source) {for (var obj in source) {
target[obj] = source[obj]
}return target
}// 测试
var a = {a: 1, b: 2} var b = {a: 2, b: 3, c: 4} var c = extend(a, b) console.log(c)
