jquery datatables：按钮后更新表单元格 [英] jquery datatables: update table cell after button click

问题描述

我们在页面中有一个表，最后有几行和一个自定义切换按钮。
表是通过页面加载，而不是通过json。

we have a table in our page, with a few rows and a custom toggle button at the end. the table is loaded via html in the page, not via json.

现在，最后的togglebutton发布到一个服务，并设置了该数据库中的记录。

now, the togglebutton at the end posts to a service and sets the follow state of that record in the database.

但是，它也应该更新该行中的另一个单元格。
但是我确定我不应该手动通过jquery通过数据表？

however, it should also make an update to another cell in that row. however i'm sure i should not do this via jquery manually but via datatables?

$('#tblFollow').dataTable({
    sDom: "t",
    aoColumns: [
      null,
      null,
      null,
      { bSortable: false }
    ]
});

$('#tblFollow').on('click', 'a.follow', function(e){
    $(this).toggleClass('active');

    // updating column 'following' here... 
    // but this only changes visually, and not the inner datatables data used for sorting
    var followingCell = $(this).parents('td').prev();
    var txt = followingCell.text() == "1" ? "0" : "1";
    followingCell.text(txt);

    return false;
});

手动示例：
现在我有一个例子，我手动更改字段，但这只是可视化，datatable仍然使用其内部数据进行排序。所以我正在寻找一种更好的方式来实现

manual example: now i have an example, where i change the fields manually, but that's only visual, the datatable still uses its inner data for sorting. So i'm looking for a way to do it better

推荐答案

这是一个可能的解决方案：

Here is a possible solution:

除了你的代码，你应该更新数据表数据，如下所示：

In addition to your code you should update the datatables data as following

var rowIndex = table.fnGetPosition( $(this).closest('tr')[0] );
var aData = table.fnGetData( rowIndex  );
aData[2] = txt; //third column

这里 jsfiddle

更好的解决方案将是使用 fnUpdate 更新数据并同时显示

And even better solution would be to use fnUpdate to update the data and display in the same time

这里 jsfiddle

// update column following here... 
var followingCell = $(this).parents('td').prev();
var txt = followingCell.text() == "1" ? "0" : "1";

var rowIndex = table.fnGetPosition( $(this).closest('tr')[0] );
table.fnUpdate( txt, rowIndex , 2);

而不是我们

Also instead of us

var followingCell = $(this).parents('td').prev();
var txt = followingCell.text() == "1" ? "0" : "1";

使用

var aData = table.fnGetData( rowIndex  );
aData[2] //use it to check if the value is 0 or 1
