如何在模态弹出窗口中的文本区域中获取值? 以及如何在我的输入字段中显示值?

Question

>我有一个文本字段，如果我单击文本字段，则会出现一个模式弹出窗口，其中包含一个文本字段"在此处输入"。现在，如果在那里输入一些文本并单击 "确定"，文本应显示在第一个文本输入字段中。

我试过了，但它不起作用。这是我失败的小提琴..

在这里摆弄

<!-- 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>

Answer 1

你可以用Javascript做到这一点。向按钮和文本区域添加id。然后在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>
