jQuery .unique()的使用

var yearArray = new Array(2009, 2009, 2010, 2010, 2009, 2010);
// still sort the array
yearArray.sort();
//$.unique(yearArray);
yearArray = uniqueArray(yearArray);

function uniqueArray(a){
temp = new Array();
for(var i = 0; i < a.length; i ++){
if(!contains(temp, a[i])){
temp.length+=1;
temp[temp.length-1] = a[i];
}
}
return temp;
}
function contains(a, e){
for(j=0;j<a.length;j++)if(a[j]==e)return true;
return false;
}
