datatables-1.10 datatables

我目前有一个datatable(1.10.18版),里面有几个js选项,但我需要让我的代码更具可重用性,我正在尝试用html5 data-*属性初始化我的datatable。

<table id="dataTable" cellspacing="0" width="100%" data-source="ajax.mysource.php">
    <thead>
        <tr>
            <th>Name</th>
            <th>Address</th>
            <th><i class="fas fa-low-vision"></i></th>
        </tr>
    </thead>
</table>

我的jQuery代码如下所示:

var dataTable = $('#dataTable').DataTable({
    processing: true,
    serverSide: true,
    ajax: $('#dataTable').data('source'),
    columns: [
        { 'data': 'name' },
        { 'data': 'address' },
        { 'data': 'visible' }
    ],
    order: [[ 1, 'asc' ], [ 0, 'asc' ]],
    responsive: true,
    nowrap: true,
    pageLength: 15,
    lengthChange: false,
    select: 'single',
    columnDefs: [
        {   targets: 0, width: "110px" },
        {   targets: 1, width: "150px" },
        {   targets: 1, render: $.fn.dataTable.render.ellipsis(80) },
        { targets: 2, render: $.fn.dataTable.render.visibilityIcon() }
    ],
    rowCallback: function(row, data, index) {
        if (data.visible == "0") {
            $(row).addClass("notVisible");
        }
    }
});

每个datatable都有一些常用的选项,但如果我可以使用html5 data-*属性直接在html中设置列、列定义和行回调,那就太好了,这样我就可以对不同的表使用相同的代码,比如:

<th data-columns="address" data-column-defs="{targets: 1, width:'150px'}" data-row-callback="function...">Address</th>

除了排序、排序和页面长度之外,我还没有发现如何使用html5-*属性。

用html5设置这个选项实际上可以用datatables实现吗。js?

首先,您需要1.10.5版,如前所述 here

从v1开始。10.5 DataTables还可以使用从HTML5数据-*属性读取的初始化选项

然后必须将数据属性放在table元素而不是column元素上。

<table  id="example"
data-column-defs='[{"targets": 0, "width": "200px"}]' 
data-page-length='2'
data-class="dataTable" 
data-order='[[ 1, "asc" ]]'
data-columns='[{"data": "name"}, {"data": "position"}]'
>
    <thead>
        <tr>
            <th>Name</th>
            <th>Position</th>
            <th>Salary</th>
            <th>Start Date</th>
            <th>office</th>
        </tr>
    </thead>

</table>

以下是完整的片段

var data = [
    {
        "name":       "Tiger Nixon",
        "position":   "System Architect",
        "salary":     "$3,120",
        "start_date": "2011/04/25",
        "office":     "Edinburgh"
    },
    {
        "name":       "Garrett Winters",
        "position":   "Director",
        "salary":     "$5,300",
        "start_date": "2011/07/25",
        "office":     "Edinburgh"
    },
    {
        "name":       "Jane Doe",
        "position":   "SW Architect",
        "salary":     "$5,300",
        "start_date": "2011/07/25",
        "office":     "Edinburgh"
    },
    {
        "name":       "John Doe",
        "position":   "SW Developer",
        "salary":     "$5,300",
        "start_date": "2011/07/25",
        "office":     "Edinburgh"
    }
];
var oTable = $('#example').dataTable({
	data: data
