提问by John Thomas
Is there any way I can remove an item from Selectize?
有什么办法可以从 Selectize 中删除项目？
Here is my a sample list:
这是我的示例列表：
- AMNT
- QTY
- NA
- 阿姆特
- 数量
- 不适用
When I pass NAit should remove particular item:
当我通过时，NA它应该删除特定项目：
$.fn.removeSelectorValue = function (value) {
var selectize = this[0].selectize;
selectize.removeItem(value);
return this;
};
This is not working. Can anyone help me with this?

removeItemremoves selecteditem identified by given value. To remove option from the list you should use removeOption
removeItem删除由给定值标识的选定项目。要从列表中删除选项，您应该使用removeOption
Example - open http://brianreavis.github.io/selectize.js/, open console and enter:
示例 - 打开http://brianreavis.github.io/selectize.js/，打开控制台并输入：
$('#select-beast')[0].selectize.removeOption(1)
to remove Chuck Tesla from available options
从可用选项中删除 Chuck Tesla

I'm late to the party but the other methods didn't work for me, I don't know if its because I was pulling in a list from a remote source?
我参加聚会迟到了，但其他方法对我不起作用，我不知道是不是因为我从远程来源获取列表？
In short there are 2 steps:
简而言之，有2个步骤：
- Get the value of the selected item
- Remove that item
- 获取选中项的值
- 删除该项目
You can obviously make this code smaller but i've left it verbose for readability
您显然可以使此代码更小，但为了便于阅读，我将其保留得很详细
var $select = $('#users').selectize();
var selectSizeControl = $select[0].selectize;
// 1. Get the value
var selectedValue = selectSizeControl.getValue()
// 2. Remove the option
selectSizeControl.removeOption( selectedValue )

$(document).on('click', 'div.selectize-input div.item', function(e) {
var select = $('#services').selectize();
var selectSizeControl = select[0].selectize;
// 1. Get the value
var selectedValue = $(this).attr("data-value");
// 2. Remove the option
select[0].selectize.removeItem(selectedValue);
select[0].selectize.refreshItems();
select[0].selectize.refreshOptions();
});
This code do not remove the item from the select, just remove it from the selected options.
此代码不会从选择中删除项目，只是从所选选项中删除它。

Was recently implementing this, and if you remove the last item, the input looks buggy (as mentioned above). A workaround (kind of hackish) is in the onItemRemovefunction, find the length of saved items, and if length == 0, use jQuery to fix the input - $('.selectize-input').css({'height':'35px'});
最近正在实现这个，如果你删除最后一个项目，输入看起来有问题（如上所述）。一个解决方法（有点hackish）在onItemRemove函数中，找到保存项目的长度，如果length == 0，使用jQuery来修复输入 -$('.selectize-input').css({'height':'35px'});
