Clear data in modal when clicking close in Laravel - php

Question

I have a modal (Bootstrap) for creating a new product. When I click the "close" button, which creates a new product, the old data still does not clear from the modal.
My code:
<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">×</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>
<div class="form-group">
<label for="">Product Type</label>
<input type="text" class="form-control" id="" name="product_type_id">
</div>
<div class="form-group">
<label for="">Price</label>
<input type="text" class="form-control" id="" name="price">
</div>
<div class="form-group">
<label for="">Status</label>
<select class="form-control input-sm m-bot15" id="" name="status">
<option value="0">Inactive</option>
<option value="1">Active</option>
</select>
</div>
<div class="form-group">
<label for="img">Image</label>
<div class="input-group">
<span class="input-group-btn">
<span class="btn btn-default btn-file">
Choose <input type="file" id="imgInp">
</span>
</span>
<input type="text" class="form-control" name="product_image" readonly>
</div>
<img id='img-upload' class="image_responsive" />
</div>
</div>
<div class="col-md-6">
<div class="form-group">
<label for="">Description</label>
<textarea class="form-control" id="" name="description"></textarea>
</div>
<div class="form-group">
<label for="">Note</label>
<textarea class="form-control" id="" name="addition_information"></textarea>
</div>
</div>
</div>
</div>
<div class="modal-footer">
<input type="submit" value="Save" class="btn btn-success">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</form>
</div>
</div>
</div>
How can I clear the data when closing the modal?

Answer 1

You can add event listener to your close button by adding an id to your close button for example id=close-btn:
document.getElementById("close-btn").addEventListener("click", function(){
document.getElementById("frmProduct").reset();
});

Answer 2

You can use hidden.bs.modal event:
This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).
The snippet:
$('#product').on('hidden.bs.modal', function(e) {
$(this).find('form').trigger('reset');
})

<!-- Button trigger modal -->
