DataTables:在服务器端搜索所有列

标签: javascript jquery json datatables

我正在为IgnitedDatatables使用DataTables(CodeIgniter库)。生成表没有问题,但如果我搜索/过滤它,一次只能过滤一列。如果我将“bServerSide”设置为false它可以工作,但后来我失去了服务器端功能。

在示例中,这个正在工作: http://datatables.net/release-datatables/examples/ajax/custom_data_property.html

虽然这不是(服务器端): http://datatables.net/release-datatables/examples/data_sources/server_side.html

运行服务器端时无法实现这一点吗?

这是我的JSON响应(缩短并替换了数据):

{"sEcho":0,"iTotalRecords":45438,"iTotalDisplayRecords":45438,"aaData":[["abc","12345","example@example.com","","","2010-01-27 22:31:10","Edit<\/a> Delete<\/a>"],["abc2"," test123","test@test.com","","","2008-06-15 22:09:33","Edit<\/a> Delete<\/a>"]],"sColumns":"fname,lname,email,phone,cellphone,created,edit"}

JavaScript代码:

$("#members").dataTable( {
    "bProcessing": true,
    "bServerSide": true,
    'sAjaxSource': '<?php echo base_url();?>members/listener',
    "fnServerData": function ( sSource, aoData, fnCallback ) {
        $.ajax( {
            "dataType": 'json',
            "type": 'POST',
            "url": sSource,
            "data": aoData,
            "success": fnCallback
        } );
    },
    "bLengthChange": false,
    "aaSorting": [[ 0, "asc" ]],
    "iDisplayLength": 15,
    "sPaginationType": "full_numbers",
    "bAutoWidth": false,
    "aoColumnDefs": [ 
        { "sName": "fname", "aTargets": [ 0 ] },
        { "sName": "lname", "aTargets": [ 1 ] },
        { "sName": "email", "aTargets": [ 2 ] },
        { "sName": "phone", "sWidth": "80px", "aTargets": [ 3 ] },
        { "sName": "cellphone", "sWidth": "100px", "aTargets": [ 4 ] },
        { "sName": "created", "sWidth": "120px", "aTargets": [ 5 ] },
        { "bSortable": false, "sName": "edit", "sWidth": "115px",   "aTargets": [ 6 ] }
    ]
});

谢谢!

嗯,如果您过滤服务器端的问题是您正在通过SQL查询进行过滤,这就是您发布的example上写的内容;

  
      
  • 过滤
  •   
  • 注意这与内置的DataTables过滤不匹配
  •   
  • 在任何字段上逐字逐句。可以在这里做,但关注效率
  •   
  • 在非常大的表上,MySQL的正则表达式功能非常有限
  •   

基本上你可以做你想做的事(正则表达式匹配所有列)但它会杀死性能服务器端。

我通常做的是为每列提供一个过滤器,我需要过滤。
