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。
