javascript - 单击按钮时显示数据表表中的所有记录

Question

当我单击 ID 为“show_all_records”的按钮时，如何显示所有记录的任何想法和线索？如果我单击 ID 为“restore_records”的按钮，数据表将恢复为默认状态，例如记录被设置回默认状态。

我可以使用“paging: false/true”，但我不知道如何以实时方式应用它。

$(document).ready(function(){

  $('#sample_table').DataTable( {
        "bSort": false,
        "pagingType": "full_numbers",
        "dom": 'T<"clear">lfrtip',
    });
  

});

<button id="restore_records">Restore records on its default state</button>

dataTables 提供了各种函数来实现这一点。所以下面是你如何做到这一点的方式。检查内联评论以获取更多信息:

DEMO

var oTable; //global variable to hold reference to dataTables
var oSettings; //global variable to hold reference to dataTables settings

$(document).ready(function(){
    oTable=$('#sample_table').DataTable( {
        "bSort": false,
        "pagingType": "full_numbers",
        "dom": 'T<"clear">lfrtip',
    }); //store reference of your table in oTable
    oSettings = oTable.settings(); //store its settings in oSettings
});

$("#show_all_records").on('click',function(){
   oSettings[0]._iDisplayLength = oSettings[0].fnRecordsTotal();
   //set display length of dataTables settings to the total records available
   oTable.draw();  //draw the table
});

$("#restore_records").on('click',function(){
    oSettings[0]._iDisplayLength=10;
   //set it back to 10
    oTable.draw();//again draw the table
});
