ページはサーバー側の処理ページを表示する前にリロードされます。なぜどんなアイデア？

Question

次のコードは、データベースにデータをポストするWebメソッドに対するいくつかのajax呼び出しでJSONオブジェクトを使用しています。

送信ボタンをクリックすると、データが処理される前にページがリロードされ、@paremeterが必要ですが提供されていないというエラーが発生します。これは、処理のためにasp.netコードビヘイビアに渡されるすべてのフォームフィールドに発生します。

なぜこれが起こっているのか把握するのが難しいです。

誰にもアイデアはありますか？分離コードで

あなたの問題は、ボタンクリックが自動的にAjaxの呼び出しが実行される前にリロードが発生し、現在のURLに<form>を提出していることかもしれません。あなたは以下のコードでボタンのこのデフォルトの動作を無効にすることができます

$("#btnSubmit").click(function (e) { e.preventDefault }); 

はまた、あなたはあなたが投稿スニペット内の重複するコードの多くを持っています。これを最適化すると、読みやすさが大幅に向上し、デバッグ方法が簡単になります。たとえば、以下の.click()はコードの行数を減らしてコードとまったく同じです。

$('#btnSubmit').click(function (e) { 
    e.preventDefault(); 

    var posts = [{ 
     data: getAllEmpData, 
     method: 'SaveEmpData' 
    }, { 
     data: getAllSourcepData, 
     method: 'SaveSourceData' 
    }, { 
     data: getAllSpouseData, 
     method: 'SaveSpousData' 
    } /* ... */ ]; 

    var $result = $('#result'); 
    $result.text(''); 

    var calls = posts.map(function (p) { 
     var data = p.data(); 
     console.log(data); 

     return $.ajax({ 
      url: 'closures.aspx/' + p.method, 
      type: 'POST', 
      contentType: 'application/json; charset=utf-8', 
      data: JSON.stringify({'empdata': JSON.stringify(data)}), 
      error: function (xhr) { 
       alert(xhr.responseText); 
      } 
     }); 
    }); 

    $.when.apply($, calls).then(function() { 
     $result.text('All complete'); 
    }); 
});
