javascript - json2html - 创建 HTML 表格

Question

我试图找到好的 JS 插件来帮助我生成 HTML <table />结构并用 JSON 数据填充它。

我找到了 json2html ，但不幸的是，我没有在插件的官方网站上看到任何有用的示例或文档，也没有看到任何我可以查看的第 3 方网站。

我创建了一个 function()这将为我生成一些随机数据，我将在这个演示示例中使用这些数据。在我将用于 json2html 的变量中存储 JSON 模板并创建一个 <div />带有一个 ID，该 ID 将用于使用此插件解析 JSON 生成的数据。

// 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 = {
  "tag": "table",

        }
      ]
    }
  ]
};

// 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，您可能会注意到我的 JSON 模板或 json2html 调用有问题。它创建无效表并为每个 JSON 数据解析生成表。很遗憾，这不是我想要的。

我的想法是创建以下模板并将所需信息解析为 <tbody /> & <tfoot />但不要重新创建它们。

<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，我无法提供 JSFiddle，因为我找不到它的任何 CDN。但这里的屏幕截图将向您展示不良结果的样子。

我知道这是我的 JSON 结构或我没有正确设置的插件调用，但如果你不介意在这里帮助我。这确实令人头疼，但也可能对其他用户有所帮助。

Answer 1

json2Html 正在一个循环内生成您的模板，其计数器等于您的 json 对象计数。所以你看到的结果没有错。如果您不想重复页眉和页脚，只需将它们用作另一个带有对象数组的模板即可。
