无法在更改其值时提交隐藏的输入

Question

我对这个问题也有同样的问题

但我找不到答案！

我在复习这个，但它对我不起作用！

请帮忙我的代码：

$(document).ready(function() {
$('#create_lop_monhoc_modal').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget)
var tenmh = button.data('tenmh')
var mamh = button.data('mamh')
var modal = $(this)
modal.find('#input_tenmh').val(tenmh).trigger("change")
modal.find('#tenmh').text(tenmh).trigger("change")
modal.find('#input_mamh').val(mamh).trigger("change")
})
});

<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js"></script>
<div class="modal fade " id="create_lop_monhoc_modal">
<div class="modal-dialog modal-dialog-centered">
<div class="modal-content">
<form action="/monhoc" method="POST">
<input type="hidden" value="" id="input_mamh" name="mamh" />
<input type="hidden" value="" id="input_tenmh" name="tenmh" />
<div class="modal-body">
<h4 id="mamh"></h4>
<div>
<div class="modal-footer">
<button type="submit" class="btn btn-success">Crate</button>
</div>
</div>
</div>
</form>
</div>
</div>
</div>
<button type="button" data-toggle="modal" data-target="#create_lop_monhoc_modal" data-tenmh="tenmh" data-mamh="mamh">                   
Open Modal
</button>

您需要学习put value或get data属性的javascript。试试这些

$(document).ready(function() {
$('#create_lop_monhoc_modal').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget);
var tenmh = button.attr('data-tenmh');
var mamh = button.attr('data-mamh');
var modal = $(this);
modal.find('#input_tenmh').val('tenmh').trigger("change")
modal.find('#tenmh').text('tenmh').trigger("change")
modal.find('#input_mamh').val('mamh').trigger("change")
})
});

<div class="modal-content">

<div class="modal-body">
<h4 id="mamh"></h4>

<div class="modal-footer">

<button type="button" data-toggle="modal" data-target="#create_lop_monhoc_modal" data-tenmh="tenmh" data-mamh="mamh">
