让您的 jquery 数据表按第一列对 DESC 进行排序。或将另一列设置为其默认排序依据答案

【问题标题】：Getting your jquery datatable to sort DESC by first column. Or setting another column as its default sortby让您的 jquery 数据表按第一列对 DESC 进行排序。或将另一列设置为其默认排序依据
【发布时间】：2012-07-04 17:44:09
【问题描述】：

我已经尝试了几个小时来解决这个问题，但它没有发生。当我加载我的表时，我需要它在第一个 col 上对 desc 进行排序。这就是我所拥有的，但没有运气。

/**
*   Makes the table in the tabs for reports
*
* @param array Holds the data for datatable.
**/
var makeTabTable = function(tableData){
    $("#tab_active_reg").dataTable({
        bJQueryUI : true,
        bDestroy : true,
        aoColumns : [
            {"sTitle" : "Seen", "sWidth" : "50px", "asSorting": [ "desc"]},
            {"sTitle" : "Sold", "sWidth" : "50px"},
            {"sTitle" : "Name", "sWidth" : "240px"}
        ],
        aaData : tableData  
        });
    $('.tabsComponent').find('.fg-toolbar').empty();
};

【解决方案1】：

只需将此选项添加到dataTable() 调用中：

aaSorting : [[0, 'desc']]

所以在你的情况下：

   $("#tab_active_reg").dataTable({
        bJQueryUI : true,
        bDestroy : true,
        aaSorting : [[0, 'desc']],
        aoColumns : [
            {"sTitle" : "Seen", "sWidth" : "50px"},
            {"sTitle" : "Sold", "sWidth" : "50px"},
            {"sTitle" : "Name", "sWidth" : "240px"}
        ],
        aaData : tableData  
    });

可以看到，是[colnumber, sortdirection]的数组，所以可以指定多个。

【讨论】：

我试过了，但它不起作用。它一直在加载 asc 上排序。 aoColumns : [ {"sTitle" : "Clicks", "sWidth" : "50px", "aaSorting" : [[0, 'asc']] }，这样对吗？
你取出了 column-def 中的 asSorting？并且您在 aoColumns 中指定了所有列（总共只有 3 个）。控制台没有错误？它对我有用...
感谢您的详细说明。我一直试图将它放在 aoColumns 中。我最初拥有它的样子，只是它类似于 aaSorting : [0, 'desc']。谢谢。

【解决方案2】：

根据最新的数据表文档，我有一个更更简单的答案。

例如，如果您想在页面的默认加载上按降序对数据表的第 4 列进行排序 strong> 然后使用此代码。

$(document).ready( function () {
  var table = $('#example').DataTable({    
     //We are simply using order property which is an array of array so multiple columns can be ordered like this.
            "order": [
                      [3, 'desc'],
      
                     ]        
            
        });
} );
