我目前有一个数据表(版本1.10.18),其中包含js的多个选项,但是我需要使代码更具可重用性,并且尝试使用html5 data- *属性初始化数据表。
<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:
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");
}
}
});
我会为每个数据表使用一些共同点,但是如果我可以使用html5 data- *属性直接在html中设置column,columnDefs和rowCallBack,那将是很棒的选择,因此我可以将相同的代码用于不同的表格,例如:
<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,我什么地方都没有找到如何使用html5- *属性的方法。
是否可以通过datatables.js使用html5设置此选项?
答案 0 :(得分:2)
首先,您需要使用here所述的1.10.5版本
从v1.10.5开始,DataTables还可以使用从HTML5 data- *属性读取的初始化选项
然后,您必须将数据属性放到表元素中,而不是列元素中。
<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>
