JavaScript - object

面向对象

var people = new Object();people.name = "DONE";people.age = "24";people.getAge = function(){alert(this.age);｝var people = [];people.name = "DONE";people.age = "24";people.getAge = function(){alert(this.age);｝people.getAge();

firefox中调试js

var a = "ABCD";console.log(a.toLowerCase());

取文件后缀名（lastIndexOf and substring function)

getExtension=function(str)｛var n = str.lastIndexOf(".");var b=str.length;var res = str.substring(n, b);return res;}console.log(getExtension("name.nampn"))；

冒泡排序

  toSort=function(arr){  for (var i=0; i<arr.length;i++){  for(var j=0;j<i;j++){  if (arr[j]>arr[i]){    var t=arr[i];        arr[i]=arr[j];        arr[j]=t;              }    }  }  return arr;};var arr=[3,6,9,4];console.log(toSort(arr));
