Question

我有一个用于创建新产品的模态（Bootstrap）。当我单击“关闭”按钮（创建新产品）时，旧数据仍然无法从模态中清除。

我的代码：

<div class="modal fade" id="product" role="dialog" aria-hidden="true" data-target="#myModal"   data-backdrop="static"  data-keyboard="false" >
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal">&times;</button>
                <h4 class="modal-title">Create new product</h4>
            </div>
            <div class="modal-body">
                <form role="form" action="{{ route('admin.product.addProduct')}}" method="post" id="frmProduct">
                    {{ csrf_field() }}
                    <input type="hidden" name="_token" value="{{ csrf_token() }}">
                    <div class="row">
                        <div class="col-md-6">
                            <div class="form-group">
                                <label for="">Product Name</label>
                                <input type="text" class="form-control" id="" name="product_name">
                            </div>

                                <label for="">Product Type</label>
                                <input type="text" class="form-control" id="" name="product_type_id">

                            <div class="form-group">

关闭模态时如何清除数据？

Answer 1

您可以通过向关闭按钮添加ID来为关闭按钮添加事件监听器，例如id=close-btn：

document.getElementById("close-btn").addEventListener("click", function(){ 
   document.getElementById("frmProduct").reset();
});

Answer 2

您可以使用hidden.bs.modal事件：

当模态完成对用户的隐藏时将触发此事件（将等待CSS转换完成）。

摘录：

$('#product').on('hidden.bs.modal', function(e) {
    $(this).find('form').trigger('reset');
})
