Question

我有一个文本字段，如果我单击该文本字段，则会显示一个模式弹出窗口，并带有文本字段“ Enter here”。现在，如果在此处输入一些文本，然后单击 '确定'，该文本应显示在第一个文本输入字段中。

我尝试过，但是没有用。这是我失败的小提琴。.

<!-- Input field -->
<input type="text" id="address" placeholder="Enter here" class="form-control" name="address" data-toggle="modal" data-target="#narratModal" />

<!-- text popup modal -->

<div class="modal fade" id="narratModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close cash-dismiss" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title modal_head" id="myModalLabel">Narration</h4>
      </div>
      <div class="modal-body">
        <label class="modal_note">Note: Only alphabets A-Z a-z number 0-9 and characters % [] () - _ . , are allowed in text</label>
        <textarea class="cash_text">
                                                                Enter Here...
                                                            </textarea>
        <span class="modal_valid">0/200 Characterts entered</span>
      </div>
      <div class="modal-footer narr_footer">
        <button type="button" class="btn btn-primary cashmodal_btn">OK</button>
      </div>
    </div>
  </div>
</div>

您可以使用Javascript执行此操作。将id添加到按钮和文本区域。然后，当单击按钮时，在输入中显示文本区域的值。例如：

document.getElementById('ok_button').addEventListener('click', function () {
document.getElementById('address').value = document.getElementById('cash_text').value
})

<input type="text" id="address" placeholder="Enter here" class="form-control" name="address" data-toggle="modal" data-target="#narratModal" />

<div class="modal fade" id="narratModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
    <div class="modal-content">
        <div class="modal-header">
            <button type="button" class="close cash-dismiss" data-dismiss="modal" aria-label="Close">
                <span aria-hidden="true">&times;</span>
            </button>
            <h4 class="modal-title modal_head" id="myModalLabel">Narration</h4>
        </div>
        <div class="modal-body">
            <label class="modal_note">Note: Only alphabets A-Z a-z number 0-9 and characters % [] () - _ . , are allowed in text</label>
            <textarea id="cash_text" class="cash_text">Enter Here...</textarea>
            <span class="modal_valid">0/200 Characterts entered</span>
        </div>
        <div class="modal-footer narr_footer">
            <button id="ok_button" type="button" class="btn btn-primary cashmodal_btn">OK</button>
        </div>
    </div>
</div>
</div>

如何从模式弹出窗口中的textarea获取值？以及如何在输入字段中显示值？
