JSONを使用した動的HTMLテーブル行の作成

Question

質問：以下のJSON構造を使用してcolspanを使用して動的表の行を作成するためのJqueryまたはjavascriptソリューションを探しています。私は、 必要な行を作成する問題に直面しています。私は多くのシナリオを試しましたが、THを追加するためにTRを見つけることはできません。

お手数をおかけします。

ここに私のJSON形式ここで

[{"data":"test","nodes":[{"data":"5.00%","nodes":[{"data":"5.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"70.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"80.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]}]},{"data":"5.00%","nodes":[{"data":"5.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"70.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"80.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]}]}]}] 

は私がするつもりはありません、私は

これに対して再帰を使用することができます。このバージョンでは、入力に含まれている値に基づいて、colspanの値も動的に決定されます。これらは1以上の場合にのみ追加されます。colspanがゼロの場合は意味がありません。

function objectToTable(data) { 
 
    var $table = $("<table>"), 
 
     $tableRows = $("tr", $table); 
 
    
 
    function recurse(data, depth) { 
 
     if (!data) return 1; 
 
     if (depth >= $tableRows.length) { 
 
      $table.append($("<tr>")); 
 
      $tableRows = $("tr", $table); 
 
     } 
 
     var totalSpan = 0; 
 
     $tableRows.eq(depth).append(data.map(function(column) { 
 
      var colspan = recurse(column.nodes, depth+1); 
 
      // Maybe you want the deepest values to be wrapped in normal TD tags: 
 
      var $th = $(column.nodes ? "<th>" : "<td>").text(column.data); 
 
      if (colspan > 1) $th.attr("colspan", colspan); 
 
      totalSpan += colspan; 
 
      return $th; 
 
     })); 
 
     return totalSpan; 
 
    } 
 
    recurse(data, 0); 
 
    return $table; 
 
} 
 

 
var data = [{"data":"5.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"70.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]},{"data":"80.00%","nodes":[{"data":"Jul 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Aug 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Sep 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Oct 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Nov 2014","nodes":[{"data":"Result","nodes":null}]},{"data":"Dec 2014","nodes":[{"data":"Result","nodes":null}]}]}]; 
 
$("body").append(objectToTable(data));

table { 
 
    border-collapse: collapse; 
 
} 
 
th, td { 
 
    border: 1px solid;

を達成しようとしています何ですJSFiddleのアイデアを参考にしてくださいあなたはこれをどうやってやることができますか？私は、クリックされたヘッダーに基づいて列を並べ替える非常に簡単な方法も含めました。このテーブルをレンダリングするために私がここで行ったことを理解した後で、プログラムによって列スパンを追加することはあまり難しくありません。それを行う方法については、document.getElementById（）。setAttribute（attributeName、value）を見てください。

ご質問があれば、私に教えてください:)
