[召唤帖]召集JavaScript内置对象扩展原型函数，要求经典、原创、分不是问题。

Array对象的几个原型方法Array.prototype.inArray = function (value) {
  for (var i = 0; i < this.length; i++) {
    if (this[i] === value) {
      return true;
    }
  }
  return false;
};Array.prototype.max = function(){
  for (var i = 1, max = this[0]; i < this.length; i++){
    if (max < this[i]) {
      max = this[i];
    }
    return max;
};Array.prototype.min = function(){
  for (var i = 1, min = this[0]; i < this.length; i++){
    if (min > this[i]) {
      min = this[i];
    }
    return min;
};

Date.prototype.format = function(format) //author: meizz
{
  var o = {
    "M+" : this.getMonth()+1, //month
    "d+" : this.getDate(),    //day
    "h+" : this.getHours(),   //hour
    "m+" : this.getMinutes(), //minute
    "s+" : this.getSeconds(), //second
    "q+" : Math.floor((this.getMonth()+3)/3),  //quarter
    "S" : this.getMilliseconds() //millisecond
  }
  if(/(y+)/.test(format)) format=format.replace(RegExp.$1,
    (this.getFullYear()+"").substr(4 - RegExp.$1.length));
  for(var k in o)if(new RegExp("("+ k +")").test(format))
    format = format.replace(RegExp.$1,
      RegExp.$1.length==1 ? o[k] :
        ("00"+ o[k]).substr((""+ o[k]).length));
  return format;
}
alert(new Date().format("yyyy-MM-dd hh:mm:ss"));

String.prototype.endsWith = function(character){
  return (character == this.charAt(this.length - 1));
};String.prototype.startsWith =  function(character){
  return (character == this.charAt(0);
};

在这儿发现一个比较多的。http://ttyp.cnblogs.com/archive/2004/10/26/56730.htmlhttp://www.cnblogs.com/Files/ttyp/Js-Lib.rar

Function.prototype.bind = function(o){
    var self = this;
    var arg  = Array.prototype.slice.call(arguments,1);
    return function(){
        self.apply(self, arg );
   }
}

i += 1;
}
else{
i += 2;
}
strTmp += ch;
}
return strTmp;
}

楼上，一定通知你。建议几点：
一、方法名最好模拟Java、.NET或VBScript的
　如:
  String.prototype.endsWith = function(){}; //Java和.NET中的String对象的endsWith方法。我建议不用endWith。
　Object.prototype.isNumeric = function(){}; //VBScript中的IsNumeric方法
二、方法命名，因为是方法，所以遵守第一个单词字母小写，第二个大写。
　这个String.prototype.trim = function(){};而不是Trim
      Object.prototype.isNumeric = function() {};而不是IsNumeric三、对已经有的方法，不封装，如
    String对象已经有indexOf方法，就不必封装出一个inStr了。indexOf也很好用啊。

也凑个热闹吧：//排除数组重复项
Array.prototype.Unique = function()
{
  var a = {}; for(var i=0; i<this.length; i++)
  {
    if(typeof a[this[i]] == "undefined")
      a[this[i]] = 1;
  }
  this.length = 0;
  for(var i in a)
    this[this.length] = i;
  return this;
};//apply call
if(typeof(Function.prototype.apply)!="function")
{
  Function.prototype.apply = function(obj, argu)
  {
    var s;
    if(obj)
    {
      obj.constructor.prototype._caller=this;
      s = "obj._caller";
    }
    else s = "this";
    var a=[];
    for(var i=0; i<argu.length; i++)
      a[i] = "argu["+ i +"]";
    return eval(s +"("+ a.join(",") +");");
  };
  Function.prototype.call  = function(obj)
  {
    var a=[];
    for(var i=1; i<arguments.length; i++)
      a[i-1]=arguments[i];
    return this.apply(obj, a);
  };
}if(typeof(Number.prototype.toFixed)!="function")
{
    Number.prototype.toFixed = function(d)
    {
        var s=this+"";if(s.indexOf(".")==-1)s+=".";s+=new Array(d+1).join("0");
        if (new RegExp("^((-|\\+)?\\d+(\\.\\d{0,"+ (d+1) +"})?)\\d*$").test(s))
        {
            s="0"+ RegExp.$1, pm=RegExp.$2, a=RegExp.$3.length, b=true;
            if (a==d+2){a=s.match(/\d/g); if (parseInt(a[a.length-1])>4)
            {
                for(var i=a.length-2; i>=0; i--) {a[i] = parseInt(a[i])+1;
                if(a[i]==10){a[i]=0; b=i!=1;} else break;}
            }
            s=a.join("").replace(new RegExp("(\\d+)(\\d{"+d+"})\\d$"),"$1.$2");
        }if(b)s=s.substr(1); return (pm+s).replace(/\.$/, "");} return this+"";
    };
}String.prototype.sub = function(n)
{
  var r = /[^\x00-\xff]/g;
  if(this.replace(r, "mm").length <= n) return this;
  n = n - 3;
  var m = Math.floor(n/2);
  for(var i=m; i<this.length; i++)
  {
    if(this.substr(0, i).replace(r, "mm").length>=n)
    {
      return this.substr(0, i) +"...";
    }
  }
  return this;
};

来玩
String.prototype.realLength = function()
{
  return this.replace(/[^\x00-\xff]/g,"**").length;
}
判断整型
String.prototype.isInteger = function()
{
    //如果为空，则通过校验
    if(this == "")
        return true;
    if(/^(\-?)(\d+)$/.test(this))
        return true;
    else
        return false;
}
是否为空
String.prototype.isEmpty = function()
{
    if(this.trim() == "")
        return true;
    else
        return false;
}

嘿嘿，大家都来给KimSoft(革命的小酒天天醉) 捧场啊

优化一下代码：
String.prototype.isContainChinese = function()
{
    var pattern = /[\u4E00-\u9FA5]/g;
    if (pattern.test(this))
        return true;
    else
        return false;
}==>String.prototype.isContainChinese = function()
{
    return /[\u4e00-\u9fa5\uf900-\ufa2d]/.test(this);
}其它的类推优化

的确，我的代码多用到变量
就拿这里来讲，这里有两句return true; return false;
我想这里就需要有两个对象来存储，浪费了资源。
而meizz的不管返回true或者false都应该存储在一个对象里。
TO meizz
除了这点之外，写成那种还有其他原因吗？

楼上两位再帮我看看这个帖子http://community.csdn.net/Expert/topic/4609/4609496.xml?temp=.1486322

还有就是不要在正则里动不动就添加 g 模式：
/^([\u4E00-\u9FA5])*$/g //String.prototype.isAllChinese
这句正则里的 g 模式若是配合以 m 模式那还说得过去，你即然没有 m 那何必要添个 g ？
还有你用的是 * 若这一个空字符串你也认为是 isAllChinese ？所以应该用+
/^[\u4e00-\u9fa5\uf900-\ufa2d]+$/var pattern = /[\u4E00-\u9FA5]/g; //String.prototype.isContainChinese
这句正则里加了一个无用的 g ，对系统消耗则相差甚大呀

TO meizz(梅花雪)
灯泡（这个是帖图），以后我写代码要多注意了。

呵呵，被挖走了正则用处可大了，有时候能起到事半功倍的效果，.net里的正则比JS的还复杂
