Question

我有一个要从JSON数据呈现的HTML表，我有三行headers，第一行显示的是total，{{1 }}和Outlets，第二个显示金额类型，分别为jayanagar，Malleshwaram，Kolar和Gross Amount，第三个显示金额栏明智的做法，然后显示完整数据的表主体

我想做的是：-

我有一个带下拉菜单的输入字段，它是用于选择多个选项的复选框
选择框是Discount，例如GST，Net Amount，Amount Type和Gross Amount，并且有一个按钮Discount
因此，当用户在选择选项后单击GST时，我要尝试的是仅显示该列用户选择的内容

我的表格代码

Net Amount

Go

由于我的代码有点长，所以我在JavaScript代码中注释了我正在做什么的行，以使其更容易

我想根据用户选择隐藏列这里的任何人都可以通过某种方法帮助我

Answer 1

执行此操作的适当方法是将列数据添加到表中，如下所示：

<table class="table table-striped table-bordered table-hover">
  <thead></thead>
  <colgroup>
    <col style="background-color:yellow; visibility: collapse;">
    <col id="total" span="4" style="background-color:red">
  </colgroup>
  <tbody>
    <tr>
      <th class="text-center">BillDate</th>
      <th colspan="4" class="text-center">Total</th>
      <th colspan="4" class="text-center">JAYANAGAR</th>
      <th colspan="4" class="text-center">MALLESHWARAM</th>
      <th colspan="4" class="text-center">KOLAR</th>
    </tr>
    ...
  </tbody>
</table>

但是有一个chrome bug可以防止可见性属性对cols或colgroups产生任何影响。

然后我将避免使用表，而是使用常规div手动构建表，并将列分组在一起。

Answer 2

请通过这些链接。根据我的观点，您可以避免选择框（如果您仅将选择框值用于隐藏列）。您可以使用以下链接中提到的方法。

`https://codepen.io/feger/pen/eDybC`

show / hide table columns using jQuery

https://api.jquery.com/hide/#hide-options

您可以使用.hide（）隐藏匹配的元素。

Answer 3

我发现您在表头中使用了grossAmount，discount，gst和netAmount之类的类……这是一件好事。

如果将这些类添加到每一行的相应单元格中，甚至会更好。您可以使用真正简单的方法来显示/隐藏单元格。

我使用了3个嵌套循环来显示更复杂的，这些结果显示了基于具有选定类的标头的index来显示单元格。

我从#To输入中选取了选定的类，该输入是用逗号分隔的单词 close 列表，用于查找列索引。

请注意，它远非最佳和有效的编码方式，但是它可以工作……并且可能对您有启发性。 ;）

$("#save").on("click",function(){

  // Get the selected classes

  $(".table tbody tr td:not(:first-child)").hide();

  // Adjust thead first row colspans
  $(".table thead tr:first th:not(:first)").attr("colspan",classes.length);

  // For each classes selected
  for(i=0;i<classes.length;i++){
    //force 3 first letters to lowercase
    var classToShow = classes[i].substr(0,3).toLowerCase() + classes[i].substr(3);

这是一个有关如何使用单元格类显示/隐藏列的示例。我在您的表的简化版本上完成了此操作...

顺便说一句，这里的表是否是“动态的”不是问题。...由于show / hide操作是在呈现表时运行的。因此，所有需要的元素都存在，并且可以针对用户触发的事件。

我使用了您拥有的4列类……还有2个类：selectable定位可能隐藏/显示的所有单元格，colspaned定位需要colspan属性的标题调整。

因此，正如您在下面看到的那样，它效率更高，因为只有一个简单的循环来收集每个4个复选框的值和相应的类。我已经将这些类放在了data属性中。

var selections = $(".checkbox-menu :checkbox");
var filterData = $("#To");
var originalColspan = $(".colspaned").attr("colspan");

selections.on("change",function(){
  
  // Clear the "Filter Data" input
  filterData.val("");
  
  // Get the selected classe
  var classes = [];
  var values = [];
  selections.each(function(){
    if($(this).is(":checked")){
      
      // Get the selected classe
      classes.push( "." + $(this).data("select") );
      
      // Value in the "filter Data" input
      values.push( $(this).val() );
    }
  });
  
  // Value in the "filter Data" input... If still useful (!)
  filterData.val(values.join(","));
  
  // Get how many selected
  var selectedAmount = classes.length;
  
  // If at least one selection
  if(selectedAmount>0){
  
    // Adjust headers colspan attr
    $(".colspaned").attr("colspan",selectedAmount);
    
    // Hide all cells
    $(".selectable").hide();
    
    // Show selected
    $(classes.join(",")).show();
  }
  
  // If no selection, show all cells
  else{
    $(".selectable").show();
    
    // Adjust headers colspan attr
    $(".colspaned").attr("colspan",originalColspan);
  }
});
