Array 去重
[javascript]
Array.prototype.distinct = function(){
var i = 0;
while( i < this.length ){
var n = this[i];
this.splice(i,1,null);
if(this.indexOf(n) < 0){
this.splice(i,1,n);
i++;
}else{
this.splice(i,1);
}
}
return this;
};
var t= [1,2,3,3,4,3,4,4,5,6];
Array.prototype.distinct= function(){
var self = this;
this.slice().sort().sort(function(a,b){
if(a==b){
var n = self.indexOf(a)&& self.splice( n ,1);
}
})
return this;
}
Array.prototype.distinct= function() {
var temp = {},n=[];
for(var i=0,len=this.length;i < len; i++) {

temp[this[i]] = 1;
n.push(this[i])
