Laravel:提交动态生成的表单字段

我正在尝试使用Ajax向控制器提交已动态生成字段的表单。就像发票一样。有日期,客户,小计,税额和ttl字段是永久字段(发票标题)。然后有n个动态生成的表单字段(发票行)。这是动态生成的html。每个输入字段都有不同的名称和ID。

<tbody id="list">
    <tr>
        <td>
            <input name="sku1" id="sku1" readonly="" type="text" value="K5693">
        </td>
        <td>
            <input name="name1" id="name1" readonly="" type="text" value="HANDLEBAR">
        </td>
        <td>
            <input name="rate1" id="rate1" readonly="" type="text" value="45.00">
        </td>
        <td>
            <input name="qty1" id="qty1" readonly="" type="text" value="2">
            </td>
        <td>
            <input name="disc1" id="disc1" readonly="" type="text" value="0">
        </td>
        <td>
            <input name="ttl1" id="ttl1" readonly="" type="text" value="90.00">
        </td>
        <td class="text-center">
            <a onclick="removeField(this)"><i class="fas fa-trash-alt"></i></a>
        </td>
    </tr>
    <tr>
        <td>
            <input name="sku2" id="sku2" readonly="" type="text" value="K5693">
        </td>
        <td>
            <input name="name2" id="name2" readonly="" type="text" value="HANDLEBAR">
        </td>
        <td>
            <input name="rate2" id="rate2" readonly="" type="text" value="45.00">
        </td>
        <td>
            <input name="qty2" id="qty2" readonly="" type="text" value="2">
        </td>
        <td>
            <input name="disc2" id="disc2" readonly="" type="text" value="10">
        </td>
        <td>
            <input name="ttl2" id="ttl2" readonly="" type="text" value="80.00">
        </td>
        <td class="text-center">
            <a onclick="removeField(this)"><i class="fas fa-trash-alt"></i></a>
        </td>
    </tr>
</tbody>

永久字段HTML

        <div class="form-group">
            <label for="date">Date</label>
            <input type="text" class="form-control" id="date" name="date" placeholder="00/00/0000"></input>
        </div>
        <div class="form-group">
            <label for="customer">Customer</label>
            <select class="form-control" id="customer">
                @foreach($customers as $customer)
                    <option value="{{$customer->id}}">{{$customer->name}}</option>
                @endforeach
            </select>
        </div>

        <div class="card p-3">
            <table>
            <tr>
                <td class="h5">SUB TOTAL</td>
                <td class="h5 text-right pr-3">AED</td>
                <td><input type="text" class="form-control text-right" id="sub_total"placeholder="00.00" value="0.00" readonly></input></td>
            </tr>                   
            <tr>
                <td class="h5">VAT</td>
                <td class="h5 text-right pr-3">AED</td>
                <td><input type="text" class="form-control text-right" id="tax" placeholder="00.00" value="0.00" readonly></input></td>
            </tr>                       
            <tr>
                <td class="h5">TOTAL</td>
                <td class="h5 text-right pr-3">AED</td>
                <td><input type="text" class="form-control text-right" id="ttl" placeholder="00.00" value="0.00" readonly></input></td>
            </tr>
        </table>                        
    </div>

点击按钮即可触发javascript:

function createData(){
    var date = document.getElementById('date').value;
    var customer = document.getElementById('customer').value;
    var sub_ttl = document.getElementById('sub_total').value;
    var tax = document.getElementById('tax').value;
    var ttl = document.getElementById('ttl').value;
}

我首先从永久字段获取值。不知道如何从n个动态生成的字段中收集值并将其传递给控制器​​。有beein对此进行了许多讨论,但无法弄清楚。有什么帮助吗?

您将必须执行以下操作:

<tbody id="body">
<tr>
    <td>
        <input name="skus[]"readonly="" type="text" value="K5693">
    </td>
    <td>
        <input name="names[]" readonly="" type="text" value="HANDLEBAR">
    </td>
    <td>
        <input name="rates[]" readonly="" type="text" value="45.00">
    </td>
    <td>
        <input name="qtys[]" readonly="" type="text" value="2">
        </td>
    <td>
        <input name="discs[]" readonly="" type="text" value="0">
    </td>
    <td>
        <input name="ttls[]" readonly="" type="text" value="90.00">
    </td>
    <td class="text-center">
        <a onclick="removeField(this)"><i class="fas fa-trash-alt"></i></a>
    </td>
</tr>

然后在您的控制器中,您将能够获得所有这样的值:

$skus = request('skus');
$names = request('names');
...
for(int i = 0 ; i < count($skus) ; i++)
 {
   $sku = $skus[i];
   $name = $names[i];
   ...
 }

如下更改代码。将<form>提交按钮放在您想要的位置。

//submit opening invoice data
        $('#invoice_form').on('submit', function(event){
            event.preventDefault();
            $.ajax({
                url:"put your url",
                method:'post',
                data:$(this).serialize(),
                dataType:'json',
                success:function(data)
                {
                    //do whatever you want
                }
            })
    });
<form id ="invoice_form">
<tbody id="body">
<tr>
    <td>
        <input name="skus[]"readonly="" type="text" value="K5693">
    </td>
    <td>
        <input name="names[]" readonly="" type="text" value="HANDLEBAR">
    </td>
    <td>
        <input name="rates[]" readonly="" type="text" value="45.00">
    </td>
    <td>
        <input name="qtys[]" readonly="" type="text" value="2">
        </td>
    <td>
        <input name="discs[]" readonly="" type="text" value="0">
    </td>
    <td>
        <input name="ttls[]" readonly="" type="text" value="90.00">
    </td>
    <td class="text-center">
        <a onclick="removeField(this)"><i class="fas fa-trash-alt"></i></a>
    </td>
</tr>
</tbody>

  <button type="submit" class="btn btn-success"><i class="fas fa-download"></i> Save</button>
  
</form>

controller.php

 public function create(Request $request){
    if($request->ajax())
    {
     $skus= $request->skus;
     $names= $request->names;
     $rates= $request->rates;
     $qtys= $request->qtys;

     for($count = 0; $count < count($skus); $count++)
     {
      $data = array(
       'skus' => $skus[$count],
       'names'  => $names[$count],
       'rates'  => $rates[$count],
       'qtys'  => $qtys[$count]
      );

      $insert_data[] = $data; 
     }

     Invoice::insert($insert_data);

     return response()->json([
      'success'  => 'Invoice Saved Successfully!'
     ]);
    }
}

您真正需要的是一种序列化整个表格的方法。

这是使用jQuery的方法:

以下是使用纯Javascript的方法:
