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。
