你可以为minimumResultsForSearch选项设置无穷大或-1

解决方案1

裁判:https://select2.org/searching # limiting-display-of-the-search-box-to-large-result-sets

$('select').select2({
    minimumResultsForSearch: -1
});

解决方案2

裁判:https://select2.org/searching # hiding-the-search-box

$('select').select2({
   minimumResultsForSearch: Infinity
});

//readonly on all select2 input
$(".select2-search input").prop("readonly", true);

版本4.0.3

尽量不要将用户界面需求与JavaScript代码混合在一起。

你可以在标记中用属性隐藏搜索框:

data-minimum-results-for-search = "无限"

标记

<select class="select2" data-minimum-results-for-search="Infinity"></select>

例子

$(document).ready(function() { $(".select2").select2(); }); <link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet" /> <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.min.js"></script> <label>without search box</label> <select class="select2" data-width="100%" data-minimum-results-for-search="Infinity"> <option>one</option> <option>two</option> </select> <label>with search box</label> <select class="select2" data-width="100%"> <option>one</option> <option>two</option> </select>

为了防止有人无意中发现这一点，现在在构造函数中有一个hideSearch选项，它似乎更接近问题所寻找的东西。

回声Select2::小部件(['名字' = >“状态”,“hideSearch”= > true,“数据”= >[1 = >“活跃”,2 = > '活动']]);

在他们的示例页面上:https://select2.org/searching#hiding-the-search-box

$(".js-example-basic-hide-search").select2({
  minimumResultsForSearch: Infinity
});

你可以试试这个

$('#select_id').select2({ minimumResultsForSearch: -1 });

它关闭搜索结果框，然后设置控件不可见
