Bootstrap-select on click get clicked value

Question

我正在使用jQuery插件:bootstrap-select.js我的HTML是select(multiple) - >选项.当用户选择或取消选择该选项时,我想获取当前单击的选项值.

示例:用户选择项目4 = console.log项目4.然后用户还选择项目2 = console.log项目2.目前我得到项目4,项目2 ...他们总是在一个数组而不是个人.

我的最终目标是根据用户选择的内容显示和隐藏页面上的div.将有多个选择选项字段.

HTML代码:

<fieldset class="dreamT">
   <select name="team" id="team" multiple class="dropdown selectpicker show-menu-arrow show-tick form-control" title="Pelaajat" data-width="100%" data-size="auto" multiple data-selected-text-format="count > 2">
    <optgroup>
        <option value="item 1">Item 1</option>
        <option value="item 2">Item 2</option>
        <option value="item 3">Item 3</option>
        <option value="item 4">Item 4</option>
        <option value="item 5">Item 5</option>
        <option disabled value="item 6">Item 6</option>
    </optgroup>
   </select>
</fieldset>

JS代码:

$("select#team").on("change", function(value){
   var This      = $(this);
   var selectedD = $(this).val();
   console.log(selectedD);
});

当前输出: ["item 1", "item 3", "item 4", "item 5"]

如bootstrap-select事件中所述,您可以使用changed.bs.select事件.

更改选择的值后将触发此事件.它通过以下4个参数:

• 事件
• clickedIndex
• NEWVALUE
• 属性oldValue

$(function () {
  $("#team").on("changed.bs.select", function(e, clickedIndex, newValue, oldValue) {
    var selectedD = $(this).find('option').eq(clickedIndex).text();
    console.log('selectedD: ' + selectedD + '  newValue: ' + newValue + ' oldValue: ' + oldValue);
  });
});
