Question

我通过jquery在表中添加了新行，然后select2不起作用

// Javascript

$("#add").click(function () {

    $("#mytable").each(function () {

        var tds = '<tr>';

        jQuery.each($('tr:last td', this), function () {

            tds += '<td>' + $(this).html() +'</td>';

        });
        tds += '</tr>';

        if ($('tbody', this).length > 0) {

            $('tbody', this).append(tds);
        } else {

            $(this).append(tds);
        }

    });
});

// HTML

<form method="POST" action="/store">

        {{ csrf_field() }}

        <h2>Invoice</h2>

        <div>

            <!-- Customer job-->

            <div class="form-group job">

            Customer job:
            <select class="customer_job" name="customer_job">

                @if(count($customers)>1)

                    @foreach($customers as $customer)

                        <option>{{$customer ->job}}</option>  

                    @endforeach


                @else 
                    <p>No posts found</p>

                @endif

            </select>

            </div>

            <!--Date-->

            <div class="form-group date">

            Date:
            <input type="date" name="date">   

            </div>

        </div>

        <br><br>
        <table id="mytable">

                <tr>
                  <th>ITEM</th>
                  <th>DESCRIPTION</th>
                  <th>QUANTITY</th>
                  <th>RATE</th>
                  <th>AMOUNT</th>
                </tr>

                <tr>
                  <td>
                        <select class="item" name="item">

                                @if(count($items)>1)
                                @foreach($items as $item)
                                    <option>{{$item ->item_name}}</option>  
                                @endforeach
                            @endif
                        </select>
                  </td>
                  <td>
                      <input type="text" name="description">
                  </td>
                  <td>
                      <input type="number" name="quantity" id="quantity" step="1">
                  </td>
                  <td>
                        <select class="rate" name="rate" id="rate">
                                @if(count($items)>1)

                                    <option>{{$item ->rate}}</option>

                </tr>
        </table><br>
        <input type="submit" value="Save" class="submit">

使用此代码更改您的js代码

var j =2;

    $("#add").on('click', function () {

    var data = '<tr><td><select class="item" name="item">@if(count($items)>1)@foreach($items as $item)<option>{{$item ->item_name}}</option>  @endforeach @endif</select></td><td> <input type="text" name="description"></td> <td> <input type="number" name="quantity" id="quantity" step="1"> </td> <td> <select class="rate" name="rate" id="rate"> @if(count($items)>1) @foreach($items as $item)  <option>{{$item ->rate}}</option>    @endforeach @endif</select></td><td><input type="number" name="amount" id="amount" readonly />&nbsp; <a href="javascript:void(0);" class="remCF" style="width:auto;font-size:28px;margin-left:1vw;color:#f33102;padding-top:6px;display:inline-block;"><i class="fa fa-times-circle"></i></a></td></tr>';


    $('#mytable tr:last').after(data);

    j++;
    $(".remCF").on('click', function () {
    $(this).parent().parent().remove();
    });

});

我希望它能起作用
