Delete a record from table using ajax in laravel 5

问题:

I want to delete the record using ajax.

view

@foreach( $products as $product )
    <tr>
        <td>{{ $product->code }}</td>
        <td>{{ $product->name }}</td>
        <td>{{ $product->display }}</td>
        <?php $time = date('d M, Y h:i:s A', strtotime($product->created_at)); ?>
        <td>{{ $time }}</td>
        <td>
            <a href="{{ url('/admin/products/' . $product->id . '/edit') }}" class="links-dark edits pull-left">
                <i class="fa fa-edit fa-lg"></i>
            </a>
            <div id="deleteTheProduct">
                {!! Form::open(['method' => 'DELETE', 'id' => 'formDeleteProduct', 'action' => ['AdminProductsController@destroy', $product->id]]) !!}
                    {!! Form::button( '<i class="fa fa-trash fa-lg"></i>', ['type' => 'submit', 'class' => 'delete text-danger deleteProduct','id' => 'btnDeleteProduct', 'data-id' => $product->id ] ) !!}
               {!! Form::close() !!}
           </div>
       </td>
   </tr>
@endforeach

controller

public function destroy( $id, Request $request ) {
    $product = Product::findOrFail( $id );

    if ( $request->ajax() ) {
        $product->delete( $request->all() );

        return response(['msg' => 'Product deleted', 'status' => 'success']);
    }
    return response(['msg' => 'Failed deleting the product', 'status' => 'failed']);
}

ajax delete

$('.deleteProduct').on('click', function(e) {
    var inputData = $('#formDeleteProduct').serialize();

    var dataId = $('#btnDeleteProduct').attr('data-id');

    $.ajax({
        url: '{{ url('/admin/products') }}' + '/' + dataId,
        type: 'POST',
        data: inputData,
        success: function( msg ) {
            if ( msg.status === 'success' ) {
                toastr.success( msg.msg );
                setInterval(function() {
                    window.location.reload();
                }, 5900);
            }
        },
        error: function( data ) {
            if ( data.status === 422 ) {
                toastr.error('Cannot delete the category');
            }
        }
    });

    return false;
});

** Edit 1 **:

Here's what I get if I just return console.log(msg)

Object {
    id: "1",
    code: "PROD-521420",
    name: "Testing the product name",
    category_id: "3",
    short_description: "This is the short description"…
}
category_id: "3"
code: "PROD-521420"
created_at: "2015-06-07 23:00:31"
deleted_at: null
description: "This is the long description"
discount_price: "125.00"
display: "Enabled"
id: "1"
meta_description: "This is the meta description"
meta_keywords: "This is the meta keywords"
meta_title: "This is the meta title"
name: "Testing the product name"
price: "150.00"
short_description: "This is the short description"
updated_at: "2015-06-08 10:04:26"

The thing is that, this deletes the product, but only the first row and not the one that is clicked.

I want to delete the product which is clicked.

Can anyone help ?

Your problem is here:

var dataId = $('#btnDeleteProduct').attr('data-id');

You are only going to get the first one, because you are using a duplicate id on all buttons.. So an id sizzle query will get you the first one.

You will see this if you dd($id) in your delete controller. It's always the id of the first. You can get the data-id attribute by querying relative to event.target.

You will want to use the debugger; statement inside your call back to test this, but the query should be something like:

$(e.target).attr('data-id');

or

$(this).attr('data-id');

The event target should be the button that was clicked, and you set the data-id on that button, so you just need to query it via the event.

We have to send request how laravel sending request for delete data in normal request response way. need to change little html

<button type="button" class="deleteProduct" data-token="{{ csrf_token() }}">Confirm</button>

$('.deleteProduct').on('click', function(e) {
    var inputData = $('#formDeleteProduct').serialize()+"&_method=delete&_token="+$(this).data(token);

    var dataId = $('#btnDeleteProduct').attr('data-id');

    $.ajax({
        url: '{{ url('/admin/products') }}' + '/' + dataId,
        type: 'POST',
        data: inputData,
        success: function( msg ) {
            if ( msg.status === 'success' ) {
                toastr.success( msg.msg );
                setInterval(function() {
                    window.location.reload();
                }, 5900);
            }
        },
        error: function( data ) {
            if ( data.status === 422 ) {
                toastr.error('Cannot delete the category');
            }
        }
    });

    return false;
});

As @Rob_vH mentioned, your problem is with how you're getting the ID in your JavaScript. Try changing this:

var dataId = $('#btnDeleteProduct').attr('data-id');

to this:

var dataId = $(this).attr('data-id');

回答4:

try This,replace your this div,

<div id="deleteTheProduct">
                {!! Form::open(['method' => 'DELETE', 'id' => 'formDeleteProduct', 'action' => ['AdminProductsController@destroy', $product->id]]) !!}
                    {!! Form::button( '<i class="fa fa-trash fa-lg"></i>', ['type' => 'submit', 'class' => 'delete text-danger deleteProduct','id' => 'btnDeleteProduct', 'data-id' => $product->id ] ) !!}
               {!! Form::close() !!}
</div>

with,

<input type='button' Value='Delete' onclick='deleteProduct($(this))' product_id='{!!$product->id!!}'/>

now made javascript function named as,

function deleteProduct(ele){
var product_id = ele.attr('product_id');
//Your Delete Product Ajax Code....
}
