bootstrap 多选搜索栏中的默认值选择未显示

Question

这个问题已经问过了，但没有解决我的问题

我想在我的项目中使用 Bootstrap Multiselect。

当我在 bootstrap 多选搜索栏中使用默认值选择时未显示

If am not using $('#example-getting-started').multiselect('select', ['1', '3'],{....}); in drop-down search bar not showing.

If am using $('#example-getting-started').multiselect({....}); in drop-down search bar showing.

我想显示带有默认值选择的搜索栏。

$(document).ready(function() {
    $('#example-getting-started').multiselect('select', ['1', '3'],{
      includeSelectAllOption: false,
      enableFiltering: true,
      includeFilterClearBtn: true,
      enableCaseInsensitiveFiltering : true
    });
  });

<select id="example-getting-started" multiple="multiple">
   <option value="1">Sunday</option>
    <option value="2">Monday</option>

Answer 1

问题是因为您为库使用的构造函数语法不正确；您不能同时初始化库和设置所选选项。

documentation 建议您应该在您的对象上初始化插件，然后在单独的调用中设置选定的选项 - 请参阅前面 link 中的 select 方法。

使用此方法表示搜索框显示正确：

$(document).ready(function() {
  let $select = $('#example-getting-started').multiselect({
    includeSelectAllOption: false,
    enableFiltering: true,
    includeFilterClearBtn: true,
    enableCaseInsensitiveFiltering: true
  });

  $select.multiselect('select', ['1', '3']);
});
