将管道设置为Select2的定界符 [英] Set pipe as the delimiter for Select2

问题描述

我有一个多选下拉菜单，我想将管道(|)设置为定界符.

I have one multiple select dropdown, and I want to set pipe (|) as the delimiter.

例如，当用户选择多个选项(例如Option1，Option2和Option3)时，则应分开(定界)如下所示的值:

For example, when a user selects multiple options (like Option1, Option2 and Option3) then it should separate (delimit) the values like this:

Option1 | Option2 | Option3

Option1|Option2|Option3

下面是我的代码:

$("#granttype").select2({ allowClear: true, tags: true, tokenSeparators: ['|'] });

我是在$document.ready()函数中编写的.

推荐答案

如果您的问题仍未解决，这就是答案！在旧版本的select2上，您必须使用'separator'而不是'tokenSeparators，像这样.

incase your problem is not resolved yet, here is the answer! On older versions of select2 you got to use 'separator' instead of 'tokenSeparators, like this.

jQuery('selector').select2({
                            separator: ";",
                            allowClear:true,
                            ...
                            ...
                               });

尽管不确定您是否可以选择select2的版本，但最好还是保留两个选项，就像这样.

Although as a fall back if you're not sure about the version of select2, the preferred way is to keep both the options, like this.

jQuery('selector').select2({
                            tokenSeparators: [';'],
                            separator: ";",
                            allowClear:true,
                            ...
                            ...
                               });
