本文實例講述了JavaScript去除數組裡重復值的方法。分享給大家供大家參考。具體如下：

var unique = function(origArr) {
  var newArr = [],
    origLen = origArr.length,
    found,
    x, y;
  for ( x = 0; x < origLen; x++ ) {
    found = undefined;
    for ( y = 0; y < newArr.length; y++ ) {
      if ( origArr[x] === newArr[y] ) {
       found = true;
       break;
      }
    }
    if ( !found) newArr.push( origArr[x] );
  }
  return newArr;
}
var myarray = ['jeffrey', 'allie', 'patty', 'damon', 'zach', 'jeffrey', 'allie', 'patty', 'damon', 'zach', 'joe'];
myarray = unique(myarray);
alert(myarray.join(', '));

希望本文所述對大家的javascript程序設計有所幫助。
