You can traverse JS Objects like this
你可以像这样遍历 JS 对象
for (var key in friendid) {
var obj = friendid[key];
for (var prop in obj) {
alert(prop + " = " + obj[prop]);
}
}
Hope this helps
希望这可以帮助
alternate
备用
for( var x in friendId )
{
alert(friendId[x]); // this would be your desired value
}

Most probably friendIDis already an array. If you call alertthe array is converted to a string and becomes a comma separated list of values.
很可能friendID已经是一个数组。如果调用alert该数组将转换为字符串并成为逗号分隔的值列表。
Note that converting an array to a string is not the same as calling JSON.stringify(where you get also brackets and double quotes around elements when they're strings)
请注意，将数组转换为字符串与调用不同JSON.stringify（当它们是字符串时，您还会在元素周围获得括号和双引号）

The JavaScript split()function is for the type string ie for eg.
JavaScriptsplit()函数用于字符串类型，即例如。
var friendid='1,34,67';
As VisioN says, when you alert an array you get comma separated values.
正如 VisioN 所说，当你提醒一个数组时，你会得到逗号分隔的值。
