Question

我想让我的消息线程进入我的模态。单击模式按钮后，我无法获得具有相同参考编号的所有消息。我的代码在接收到传递给控制器的refNumber之前首先执行查询。请帮我解决这个问题。这些是我的代码。

这是我的控制器（HomeController）

ProcessStartInfo sigCheckProcess = new ProcessStartInfo();
sigCheckProcess.FileName = "\\sigcheck64.exe";
sigCheckProcess.Arguments = "-a -h -i -l -s " ;
sigCheckProcess.RedirectStandardOutput = true;
sigCheckProcess.UseShellExecute = false;
sigCheckProcess.CreateNoWindow = true;

using (Process exeProcess = Process.Start(sigCheckProcess))
{
    exeProcess.WaitForExit();
    string line;
    using (System.IO.StreamWriter writer = new System.IO.StreamWriter("output.txt")) // output txt file.
    {
        using (System.IO.StreamReader reader = new System.IO.StreamReader(Path.Combine(@"c:\temp\", "test.txt")))  // replaces sigCheckProcess.StandardOutput
        {
            while (!reader.EndOfStream)
            {
                line = reader.ReadLine();
                writer.WriteLine(line);
            }
        } 
    } 
}

这是我的javascript函数

   public function getAllMessage(Request $request){
 $refNumber = $request->get('refNumber');



    $messageThread = DB::TABLE('i_di_thread')
     ->SELECT('message')
     ->WHERE('refNumber', $refNumber);
     return view ('showInquiries', ['messageThread'=>$messageThread]);

}

这是我的刀刃

 $('#inquire_t tbody').on('click','#mensahe',function(){
           var refNumber = $(this).attr('value');

        getMessageThread(refNumber);

        function getMessageThread(refNumber){
            $.ajax({
                url: 'getMessageThread',
                type: 'GET',
                headers: {'X-CSRF-TOKEN':$('meta[name="csrf-token"]').attr('content')},
                data: 'refNumber='+refNumber,
                dataType: 'text',
                success:function(msg){
                }//each
            });
        }

Answer 1

DB::TABLE('i_di_thread')
     ->SELECT('message')
     ->WHERE('refNumber', $refNumber);

将返回Illuminate/Database/Eloquent/Builder实例。 Check here

添加->get()以作为“选择”语句执行查询。 Check here

完整代码：

public function getAllMessage(Request $request){
    $refNumber = $request->get('refNumber');
    $messageThread = DB::table('i_di_thread')
                     ->select('message')
                     ->where('refNumber', $refNumber)
                     ->get();
    return view ('showInquiries', ['messageThread'=>$messageThread]);

}

您正在使用刀片显示数据，而不是异步显示。

Check this answer if you want to dynamically get data and to display in modal.

注意： 使用optional函数访问属性而不会引起错误。

示例：

<div class="row" style=" margin-left: 30px; margin-bottom: 5px; left: 20px; width: 550px; height: 200px; overflow: auto;">
                    <div>
                        @foreach ($messageThread as $thread)
                                {{optional($thread)->message}} {{-- accessing property without causing error --}}
                                <br>
                        @endforeach
                    </div>
                    <br>
                </div>

Answer 2

您应该尝试以下操作：

public function getAllMessage(Request $request){
 $refNumber = $request->get('refNumber');



    $messageThread = DB::TABLE('i_di_thread')
     ->SELECT('message')
     ->WHERE('refNumber', $refNumber)->get();
     return view ('showInquiries', ['messageThread'=>$messageThread]);

}

无法以模式输出所有具有相同ID的数据
