Question

我正在将数组中的数据呈现为数据表。该表分为三列：ImageName，Location和Brand。基于图像名称，我想动态过滤数据表并仅显示具有图像名称的那些行。图像名称最初是通过click事件提供的。一个最小的工作示例如下：

</head>
<body>

  <div id="annotationDetail">
    <table id="annTable" class="display" cellspacing="0">
        <thead>
            <tr>
                <th>ImageName</th>
                <th>Location</th>
                <th>Brand</th>
            </tr>
        </thead>  
    </table>                
  </div>
</body>
</html>

<script type="text/javascript">
function getAnnotations() {
  var annotations = [];
  var clickedImg = "Image1";
  annotations = [["Image1","Forest1","Theme1"],["Image1","Forest1","Theme2"],["Image2","Forest2","Theme3"]]
  $('#annTable').DataTable({
       "data" : annotations,
       "columns" : [
        {"ImageName" : annotations[0]},
        {"Location" : annotations[1]},
        {"Brand" : annotations[2]}
       ] 
      })
}
window.addEventListener('load', getAnnotations,false);
</script>

我对数据表是完全陌生的，并且以前很少使用它。进一步采取任何帮助都会有很大帮助。

Javascript根据列值过滤数据表
