使用JSON創建動態HTML表行

Question

問題：正在尋找Jquery或javascript解決方案，使用以下JSON結構使用colspan創建動態表行。 我面臨創建所需行的問題。 我已經嘗試了許多方案，但是找不到TR來附加TH。

非常感謝您的幫助。

這是我的JSON格式

[{"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}]}]}]}]}]

這是我想要達到的目標

我無意為您完成任務，但希望這個JSFiddle可以幫助您了解如何進行此操作。 我還提供了一種非常簡單的方法，可根據所單擊的標題對列進行排序。 在理解了我在此處呈現此表所做的工作之后，以編程方式添加colspans並不難。 看一下document.getElementById（）。setAttribute（attributeName，value）來做到這一點。

有任何問題請告訴我:)

您可以為此使用遞歸。 此版本還將根據輸入內容動態確定colspan值。 僅當大於1時才添加它們。請注意， colspan為零是沒有意義的。

 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; }
