jquery - fnTables() in jQuery is undefined

Question

I'm trying to get all tables (which are dataTables) on a page,

CODE:

$(window).load(function(){
    if($.fn.dataTable)
    {
        var tables = $.fn.dataTable.fnTables();
    }
});

Getting the following error,

has no method 'fnTables'

$.fn.dataTable is defined and no errors there, so, I searched for fnTables in the jquery.dataTables.js file and I couldn't find it.

But, .fnTables() is THE way to do what I want as per the datatables site.

What can I do?

DataTable version is 1.9.0

Answer 1

我猜问题是没有fnTables()方法是dataTables 1.9.0。

我刚刚下载并查看了新文件（1.9.4），它有方法.fnTables()。

可惜，虽然网站上没有记录。

Answer 2

你有没有先初始化表格？

$('#ss_list').dataTable({
    "bJQueryUI": true,
    "sPaginationType": "full_numbers",
    "sDom": '<"H"lTfr>t<"F"ip>'.
    // ...
});

var table = $.fn.dataTable.fnTables(true);
if ( table.length > 0 ) {
    alert('You had created a dataTable!');
}
