[英]Remove one item from selected elements in select2
I have a multiselect with many options. 我有很多选择的多重选择。 When 'everybody' is selected it removes other selected, if other are selected and the 'everybody' is selected it should remove it.
当选择“所有人”时,它将删除其他选中的对象;如果选择了其他人,并且选择了“所有人”,则应删除它。
To remove the other and keep the item 'everybody' it's ok. 删除另一个并保留“所有人”项目就可以了。 But I have problem to keep other and only remove everybody.
但是我有问题要保留其他人,而只能将所有人撤离。
For the moment I have something like : 目前,我有这样的事情:
resetGroupSelectionWhenEverybody: function() {
$(".group_ids").on("select2:select", function (e){
if (e.params.data.text === 'everybody') {
$('#scheduled_publication_groups_ids').select2({width: '50%'}).val(group_everybody_id).trigger("change");
} else {
if ($('[title="everybody"]').length > 0) {
var idToRemove = 0;
groupIdsData = $('#scheduled_publication_groups_ids').select2('data');
groupIdsData.forEach(function(e, i) {
if (e.text === 'everybody') {
idToRemove = i;
}
});
groupIdsData.splice(idToRemove, 1);
$('#scheduled_publication_groups_ids').select2({'data': groupIdsData}).trigger("change");
}
}
});
},
With this code groupIdsData
is tonly the selected elements I want (all expect everybody
's group). 有了这个代码
groupIdsData
是通联我想选择的元素(所有期待everybody
的小组)。 But after I'm stuck to change the view. 但是在我坚持要改变观点之后。
select2({'data': groupIdsData})
doesn't seems to be the right choice. select2({'data': groupIdsData})
似乎不是正确的选择。
Few things : 一些事情 :
idToRemove
properly idToRemove
The answer is to use select2('val')
to get a array of ids, and then work with this. 答案是使用
select2('val')
获取ID数组,然后使用它。 Code is better using .val()
not full select2 objects. 使用
.val()
而不是完全select2对象的代码更好。
resetGroupSelectionWhenEverybody: function() {
$(".group_ids").on("select2:select", function (e){
if (e.params.data.text === 'everybody') {
$('#scheduled_publication_groups_ids').select2({width: '50%'}).val(group_everybody_id).trigger("change");
} else {
if ($('[title="everybody"]').length > 0) {
groupIds = $('#scheduled_publication_groups_ids').select2('val');
groupToKeep = groupIds.splice( $.inArray(group_everybody_id, groupIds), 1);
$('#scheduled_publication_groups_ids').select2({width: '50%'}).val(groupToKeep).trigger("change");
}
}
});
},
