本文实例讲述了JavaScript去除数组里重复值的方法。分享给大家供大家参考。具体如下：

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(', '));

希望本文所述对大家的javascript程序设计有所帮助。
