jQuery DataTable - 隐藏行的方式 [英] jQuery DataTable - Hide rows the intended way

问题描述

谢谢你的时间。

我们目前正在开发基于网络的CRM。我们使用的是

而不是使用 .fnFilter（）是这样工作ALONG WITH，所以用户仍然可以使用右上角的过滤框（默认情况下，我看到你的右下角）进一步过滤您选择显示的结果。换句话说，说你隐藏所有已完成项目，因此用户只能在表中看到不完整的项目，然后仍然可以过滤笔记本电脑表，只能看到两个不完整的行在他们的描述中有笔记本电脑

Thank you for taking of your time.

We are currently working on a web-based CRM. The project is going great except for a frustrating issue.

we are using the DataTable jQuery plug-in for almost every sortable tables in the application. Here is a list of active incidents.

As you can see, the third column represents the type of the incidents (ticket, change request, service request, etc.)

Users requested a filter box placed on top of the previous table to filter the incidents types. For instance, if you choose "Ticket only", every other type will be hidden. Up until now, everything is working.

In order to do so, every row has a CSS class that represents the incident type.

• Row #1 : class="ticket"
• Row #2 : class="changeRequest"

When the filter box value changes, the following javascript code is executed

$('table.sortable').each(function() {
    for (var i = 0; i < rows.length; i++) {
        if ($(rows[i]).hasClass(vClass)) $(rows[i]).hide();
    }
});

where

• vClass = The CSS class representing the incident type
• rows = All dataTable rows, got from "$(SomeDatatable).dataTable().fnGetNodes();"
• $('table.sortable') = All dataTables

Now, fasten your seatbelts (French liner). When you implicitly hide a row, dataTable still counts it. Here is the fabulous result.

That being explained, there goes the main question : How am I supposed to tell dataTable that I want to hide rows without deleting them forever? DataTable already has a filter box but I need it to work independently along with the type filter box (not in image).

Is there a way to add a second filter, maybe?

Thanks again for your time and sorry if I made some teeth grind (another French phrase) as English is not my native language.

解决方案

You need to write a custom filter for that table. Example:

$.fn.dataTableExt.afnFiltering.push(function (oSettings, aData, iDataIndex) {
    if ($(oSettings.nTable).hasClass('do-exclude-filtering')) {
        return aData[16] == '' || $('#chkShowExcluded').is(':checked');
    } else return true;
});

In that example we dynamically add and remove the 'do-exclude-filtering' class to a table, and if it has the class, it checks each row to see if a given cell has a value. The logic can be anything you can dream up, just keep it fast (this is executed for every row, on every draw, for every table on the page (note it's added to a 'global' array in DT, not an individual instance)

Return true to include the row, return false to hide the row

Here is the datatable reference to use the afnFiltering capabilities: http://datatables.net/development/filtering

The advantage to this instead of using .fnFilter() is that this works ALONG WITH, so the user can still use the filtering box in the top right (by default, I see yours is bottom right) to further filter the results you choose to show them. In other words, say you hide all 'completed' items, so the user only sees 'incomplete' items in the table. Then they can still filter the table for 'laptop' and see only the rows that are BOTH incomplete and have 'laptop' in their description
