$(function () { var box = [];});function obj1() { var obj = Object(); obj.a = "a1"; obj.b = "b1"; obj.c = 10; alert(obj.a + "|" + obj.b + "|" + obj.c);}function obj2() { var obj = { a: 'a1', b: 'b1', c: 10 } alert(obj.a + "|" + obj.b + "|" + obj.c);}function array1() { var box = []; box[0] = "a1"; box[1] = "b1"; box.push("c1"); alert(box);}function array2() { var box = []; box[0] = "a1"; box[1] = "b1"; box.push("c1"); alert(box.join("")); alert(box.join("!"));}function array3() { var box = ["a", "a1", "a2", "a3"]; box[0] = "a1"; box[1] = "b1"; box.push("c1"); alert(box); box.pop(); alert(box); box.shift(); alert(box); box.unshift("a0"); alert(box);}function array4() { var box = ["a", "a1", "a2", "a3", "a4", "a5"]; alert(box+"所有数"); alert(box.slice(1) + "取从1后面的数"); alert(box.slice(2, 4) + "取从2到4的数,不包括4"); alert(box.splice(1, 3) + "取从1开始3个数");}
