Ajax jQuery选项卡中的数据表

I would like to combine datatables with dynamically loaded jquery tabs and don't know how to do it.

Here is my code:

index.jsp:

    $(document).ready(function() {
        $( "#tabs" ).tabs({
            beforeLoad: function( event, ui ) {
                ui.jqXHR.fail(function() {
                    ui.panel.html(
                      "Couldn't load this tab. We'll try to fix this as soon as possible. "+ 
                      "If this wouldn't be a demo." );
                });
            }
        });

        $('#example').DataTable();
    });

<div id="tabs">
    <ul>
        <li><a href="ajax/tab.jsp?a=1">Tab 1</a></li>
        <li><a href="ajax/tab.jsp?a=2">Tab 2</a></li>
        <li><a href="ajax/tab.jsp?a=3">Tab 3</a></li>
        <li><a href="ajax/tab.jsp?a=4">Tab 4</a></li>
    </ul>
</div>

tab.jsp:

<table id="example" class="display" style="width:100%">
    <thead>
        <tr>
            <th>Name</th>
            <th>Position</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Tiger Nixon</td>
            <td>System Architect</td>
        </tr>
        <tr>
            <td>Garrett Winters</td>
            <td>Accountant</td>
        </tr>
    </tbody>
</table>

When we click Tab it will load ajax/tab.jsp?a=1 in a dynamic div.

So this happens each time you click a Tab.

But your Datatable code is written just once which will get executed before the jsp file is loaded

So your datatable doest show up.

To resolve this

You need to call $('#example').DataTable(); each time a Tab is clicked
And make sure you call if after your jsp content is loaded.

You can use tabsbeforeload event of Tabs.

Note:

I have added timeout just to delay things so that jsp is loaded. If yous jsp takes more time to load try increasing timeout value.

Code:

            $(function () {
                $("#tabs").tabs({
                    beforeLoad: function (event, ui) {
                    // load first time
                        setTimeout(function () {
                            $('#example').DataTable();
                        }, 30);

                        ui.jqXHR.fail(function () {
                            ui.panel.html(
                                "Couldn't load this tab. We'll try to fix this as soon as possible. " +
                                "If this wouldn't be a demo.");
                        });
                    }
                });

                // before tabload
                $("#tabs").on("tabsbeforeload", function (event, ui) {
                    console.log("dd");
                    $("#example").remove();  // to avoide duplicate id as Datatable will not load for other Tabs
                    setTimeout(function () {
                        $('#example').DataTable();
                    }, 30);
                });
