Question

我有一个这样的清单：

<p>Please select :</p>

<script type="text/javascript"></script>

<select id='pre-selected-options1' multiple='multiple'>
    <option value='elem_1' selected>1</option>
    <option value='elem_2'>2</option>
    <option value='elem_3'>nextoption</option>
    <option value='elem_4' selected>option 1</option>
    <option value='elem_100'>option 2</option>
  </select>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0/jquery.min.js"></script>
 <script src="js/jquery.multi-select.js"></script>
  <script type="text/javascript">
  $('#pre-selected-options1').multiSelect();
  </script>
</div>

我有一个文本框，我需要将文本框值添加到此列表中。暂时我需要它，就像每当页面重新加载时，所有输入都被重置。稍后我将连接到db。

<label>Enter: </label>
<input type="text" name="" class="input-default"><button type="button" class="btn btn-success btn-sm m-b-10 m-l-5">Add</button>

如何在按钮单击时将文本框中输入的值添加到此列表中？

<div>
    <select id="Select1" name="Select1">
        <option>Option1</option>

        <option>Option3</option>

    </select>
    <input id="Text1" type="text" />
    <input id="Button1" type="submit" value="button" />
</div>

js中的

使用jquery：

$(document).ready(function() {
        $("#Button1").click(function() {
            $('#Select1').append($("<option>" + $('#Text1').val() + "</option>"));
            return false;
        });
    });
