问题描述
我正在使用jQuery DataTables,并且我一直试图在过去2天内将工具提示添加到我的数据表的Header列中无济于事。
I'm using jQuery DataTables and I have been trying to add tooltips to the Header column of my datatables for the past 2 days to no avail.
我在datatables网站上使用了这个例子,其中工具提示被添加到行数据中,但是没有用。我只看到一个工具提示,它甚至没有得到列的标题。
I have used the example on the datatables website where tooltips were added to the row data, but that didn't work. I only see one tooltip, and it does not even get the title of the column.
以下是我到目前为止的代码。
Below is the code I have so far.
if (oTable != null) {
oTable.fnClearTable();
oTable.fnAddData(columnData);
} else {
oTable = $('#caseDataTable').dataTable({
"bDestroy": true,
"aaData": columnData,
"aoColumnDefs": columnNames,
bFilter: true,
bAutoWidth: true,
autoWidth: true,
"responsive": true,
dom: 'Bfltip',
buttons: [
{
extend: 'colvis',
postfixButtons: ['colvisRestore'],
collectionLayout: 'fixed two-column'
}
],
"fnDrawCallback": function() {
if (typeof oTable != 'undefined') {
$('.toggleCheckBox').bootstrapToggle({});
}
$('#caseDataTable thead tr').each(function () {
var sTitle;
var nTds = $('td', this);
var columnTitle= $(nTds[0]).text();
this.setAttribute('title', columnTitle);
});
/* Apply the tooltips */
$('#caseDataTable thead tr[title]').tooltip({
"delay": 0,
"track": true,
"fade": 250
});
}
});
}
推荐答案
您的代码存在多个问题:
There are multiple issues with your code:
- 你有不正确的CSS选择器,你应该定位
th
元素而不是tr
。 - 是一个合适的地方,因为你只需要做一次。
- You have incorrect CSS selectors, you should be targeting
th
elements and nottr
. initComplete
is a proper place to do this since you only need to do it once.
以下示例适用于Bootstrap Tooltip。相应地调整到工具提示插件。
My example below is for Bootstrap Tooltip. Adjust to your tooltip plugin accordingly.
$(document).ready(function() {
var table = $('#example').DataTable( {
"ajax": 'https://api.myjson.com/bins/qgcu',
"initComplete": function(settings){
$('#example thead th').each(function () {
var $td = $(this);
$td.attr('title', $td.text());
});
/* Apply the tooltips */
$('#example thead th[title]').tooltip(
{
"container": 'body'
});
}
});
});
