I am trying create interactive shopping cart using jQuery, but splice issue ruined everything, because when I am delete element directly it works perfect to me, but than I am going to dynamically changes it doesn't work deleting random elements in array even after updates indexes.
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<div id="myDIV2"></div>
<div id="myDIV"></div>
<script>
var wishlistArray = ["Item1", "Item2", "Item3", "Item4", "Item5"];
function wishlist_show() {
var wishlistArrayDom = "";
jQuery.each(wishlistArray, function (i, wishlistID) {
wishlistArrayDom += '<div><a href="javascript:;" class="rem-from-wishlist" value="' + i + '">Remove( ' + wishlistID + ' )</a></div>';
});
$('#myDIV').empty();
$('#myDIV').html(wishlistArrayDom);
wishlist_update_rem();
console.log('All: ' + wishlistArray.length);
console.log('Arr: ' + wishlistArray);
}
function wishlist_rem(num) {
console.log('Value: ' + $(this).attr('value'));
console.log('All: ' + wishlistArray.length);
console.log('Arr: ' + wishlistArray);
$(this).parent().slideUp("slow", function () {
console.log(wishlistArray.splice($(this).attr('value'), 1));
wishlist_show();
});
$('#myDIV2').append('<br>Remove ' + wishlistArray[parseInt($(this).attr('value'))] + ' of element' + +$(this).attr('value'));
}
wishlist_show();
function wishlist_update_rem() {
$(".rem-from-wishlist").unbind("click");
$(".rem-from-wishlist").click(wishlist_rem);
}
</script>
Jsfiddle example
UPDATE: Solved by myself, thanks to all, stackoverflow is best.

It's not an issue with splice()
, it's an issue with your scoping of this
.
Change your removal function to this:
function wishlist_rem(num) {
var idx = parseInt($(this).attr('value')));
$(this).parent().slideUp("slow", function () {
wishlistArray.splice(idx, 1));
wishlist_show();
});
$('#myDIV2').append('<br>Remove ' + wishlistArray[parseInt($(this).attr('value'))] + ' of element' + +$(this).attr('value'));
}
