json2html - 創建 HTML 表格

Question

我試圖找到好的 JS 插件來幫助我生成 HTML <table />結構並用JSON數據填充它。

我找到了json2html ，但不幸的是，我在插件的官方網站上沒有看到任何有用的示例或文檔，也沒有我可以查看的任何 3rd 方網站。

我創建了一個function() ，它將為我生成一些隨機數據，我將在此演示示例中使用。 將 JSON 模板存儲在我將用於json2html 的變量中，並創建了一個帶有 ID 的<div /> ，該 ID 將用於使用此插件解析 JSON 生成的數據。

// Demo function to generate random content
// ->
function generateChartData() {
 for (var i = 0; i < 5; i++) {
    var file_id = Math.floor(Math.random() * 90000) + 10000,
        file_name = 'Dummy File ' + Math.floor(Math.random() * 20) + 30 + '.zip',
        file_clicks = Math.round(Math.random() * 480) + 820,
        file_downloads = Math.round(Math.random() * 160) + 420,
        file_conversion = (file_clicks / file_downloads).toFixed(2),
        file_profit = Math.round(Math.random() * 120) + 310,
        file_cpa = (file_profit / file_downloads).toFixed(2),
        file_epc = (file_profit / file_clicks).toFixed(2);

    chartData.push({
      file_id: file_id,
      file_name: file_name,
      file_clicks: file_clicks,
      file_downloads: file_downloads,
      file_conversion: file_conversion,
      file_cpa: file_cpa,
      file_epc: file_epc,
      file_profit: file_profit
    });
  }

  // create variables but no values
  var total_clicks, total_downloads, total_conversion, total_profit, total_cpa, total_epc;
}
// <-

// Create html template for further json parsing
var template = {

        }
      ]
    }
  ]
};

// Empty array for json data
var chartData = [];

// Calling DEMO function to generate json data
generateChartData();

// Parse json data and generate html
$("#json-parse").json2html(chartData, template);

但是，您可能會注意到我的JSON模板或json2html調用有問題。 它創建無效表並為每個 JSON 數據解析生成表。 所以不幸的是，這不是我想要的。

我的想法是創建以下模板並將所需信息解析為<tbody /> & <tfoot />但不要重新創建它們。

<table class="table table-striped table-hover">
<thead id="json-head">
    <tr>
        <th>ID</th>
        <th>File Name</th>
        <th>Clicks</th>
        <th>Downloads</th>
        <th>Conversion</th>
        <th>Average CPA</th>
        <th>EPC</th>
        <th>Profit</th>
    </tr>
</thead>

<tbody id="json-body">
    <tr>
        <td>${file_id}</td>
        <td>${file_name}</td>
        <td>${file_clicks}</td>
        <td>${file_downloads}</td>
        <td>${file_conversion}</td>
        <td>${file_cpa}</td>
        <td>${file_epc}</td>
        <td>${file_profit}</td>
    </tr>
</tbody>

<tfoot id="json-foot">
    <tr>
        <td colspan="2">Total / Average</td>
        <td>${total_clicks}</td>
        <td>${total_downloads}</td>
        <td>${total_conversion}</td>
        <td>${total_cpa}</td>
        <td>${total_epc}</td>
        <td>${total_profit}</td>
    </tr>
</tfoot>

不幸的是，我無法提供 JSFiddle，因為我找不到任何 CDN。 但這里的屏幕截圖將向您展示不想要的結果是什么樣子。

我知道這是我的 JSON 結構或我沒有正確設置的插件調用，但如果你不介意在這里幫助我。 這確實令人頭疼，但也可能對其他用戶有所幫助。

Answer 1

json2Html正在循環內生成模板，該循環的計數器等於您的 json 對象計數。 所以你看到的結果沒有錯。 如果您不想重復頁眉和頁腳，只需將它們用作具有對象數組的另一個模板。
