给数组去除重复值

Array.prototype.distinct = function() {
var arr = this,
result = [],
i,
j,
len = arr.length;
for (i = 0; i < len; i++) {
for (j = i + 1; j < len; j++) {
if (arr[i] === arr[j]) {
j = ++i;
}
}
result.push(arr[i]);
}
return result;
}

2.给json数组对象去除重复值

for (var i = 0; i < customerIds.length; i++) {
for (var j = i + 1; j < customerIds.length;) {
if (customerIds[i].code == customerIds[j].code && customerIds[i].shootOn == customerIds[j].shootOn && customerIds[i].siteId == customerIds[j].siteId && customerIds[i].cardBagPPUrl == customerIds[j].cardBagPPUrl) {
customerIds.splice(j, 1)
} else j++
}
}
