I have an array and filled its values like that:
$('#list input:checked').each(function() {
deleteRecordIdsStr.push($(this).attr('name'));
});
I use that for my array:
deleteRecordIdsStr = deleteRecordIdsStr.join("-");
So I have an array like that. Let's accept that I pushed 10, 20, 30 to it at first and after that I made join.
How can I iterate over that array and get 10, 20 and 30 again?
var ids = deleteRecordIdsStr.split("-");
split is a String method that creates an array.
and the iteration will be:
for (var i = 0, l = ids.length; i <l; i++){
//something with ids[i]
}
The "standard" method is to use a forloop:
for (var i = 0, len = deleteRecordIdsStr.length; i < len; i++) {
alert(deleteRecordIdsStr[i]);
}
But jQuery also provides an each method for arrays (and array-like objects):
$.each(deleteRecordIdsStr, function(item, index) {
alert(item);
});
You can use the jQuery each function to easy iterate through them.
$.each(deleteRecordIdsStr.split('-'), function() {
// this = 10, 20, 30 etc.
});
for loop on an Array. Admittedly it's a valid style choice. It just feels very unnecessary. Especially when he cares about order, you shouldn't use an orderless each loop.
Whenever you encounter an egregiously sloppy, no-effort-expended post, or an answer that is clearly and perhaps dangerously incorrect, vote it down! You already admitted it is a style issue. Calm down with the down votes.
