How to apply the jQuery plug-in datatables for table manipulation-JS Tutorial-php.cn

This time I will show you how to apply the jQuery plug-in datatables for operating tables, and what are the application Notes of the plug-in datatables for jQuery operating tables. The following is a practical case, let's take a look.

1. Introduction to Datatables

DataTables is a jQuery table plug-in. This is a highly flexible tool based on progressive enhancements that will add advanced interactive controls and support for any HTML form. Main features:

Automatic paging processing
##Instant formData filtering
Data sorting and Data typeAutomatic detection
Automatic processing Column width
Can be customized through CSS style
Supports hidden columns
Ease of use
Scalability and flexibility
Internationalization
Dynamic creation of tables
Free ’s

2. How to use When doing the backend, there are no artists and front-end engineers to cooperate with you in making the page. In order to display the data and have certain For aesthetics, we can use jQuery's DataTables plug-in to help us complete the task
1. The default configuration of DataTables

 $(document).ready(function() { 
$('#example').dataTable(); 
} );

2. Some basic attribute configurations of DataTables

 "bPaginate": true, //翻页功能 
"bLengthChange": true, //改变每页显示数据数量 
"bFilter": true, //过滤功能 
"bSort": false, //排序功能 
"bInfo": true,//页脚信息 
"bAutoWidth": true//自动宽度

3. Data sorting

$(document).ready(function() { 
$('#example').dataTable( { 
"aaSorting": [ 
[ 4, "desc" ] 
] 
} ); 
} );

Copy after login

Start from column 0, end with column 0 4 columns in reverse order

4. Hide some columns

$(document).ready(function() { 
$('#example').dataTable( { 
"aoColumnDefs": [ 
{ "bSearchable": false, "bVisible": false, "aTargets": [ 2 ] }, 
{ "bVisible": false, "aTargets": [ 3 ] } 
] } ); 
} );

5.Internationalization

$(document).ready(function() { 
$('#example').dataTable( { 
"oLanguage": { 
"sLengthMenu": "每页显示 _MENU_ 条记录", 
"sZeroRecords": "抱歉， 没有找到", 
"sInfo": "从 _START_ 到 _END_ /共 _TOTAL_ 条数据", 
"sInfoEmpty": "没有数据", 
"sInfoFiltered": "(从 _MAX_ 条数据中检索)", 
"oPaginate": { 
"sFirst": "首页", 
"sPrevious": "前一页", 
"sNext": "后一页", 
"sLast": "尾页" 
}, 
"sZeroRecords": "没有检索到数据", 
"sProcessing": "<img src=&#39;./loading.gif&#39; />" 
} 
} ); 
} );

6. Sorting function:

$(document).ready(function() { 
$('#example').dataTable( { 
"aoColumns": [ 
null, 
{ "asSorting": [ "asc" ] }, 
{ "asSorting": [ "desc", "asc", "asc" ] }, 
{ "asSorting": [ ] }, 
{ "asSorting": [ ] } 
] 
} ); 
} );

7. Data acquisition supports 4 types: as follows

•DOM Document Data
##• Javascript array js array
##•Ajax source Ajax request data
•Server side processing Server-side data

Example explanation

1. Requirements: As shown in the figure below, add, edit, and delete the contents of datatables.

2. Analysis: Add function---click the add button to pop up a dialog box to add new content.

Editing function---Click datatables to select a row. The row changes color, which means it has been selected. Click the edit button to pop up the dialog. The content in this dialog is the content of the row we selected. If no row is selected and the edit button is clicked, the dialog will not pop up. When a row in datatables is double-clicked, a dialog will also pop up, and the color of the double-clicked row will change. The content in the dialog is the content of the row we double-clicked.

Deletion function---click datatables to select a row, click the delete button, and a warning box will pop up, prompting you whether to delete the selected content. When nothing is selected, clicking the delete button will not pop up a warning box and the content will not be deleted.

3. Encoding:
Attributes//Name

 <table id="gridtable" class="gridtable">//声明jquery datatables 
   <thead> 
     <tr> 
       <th>Name 
       </th> 
       <th>Value

    </tr> 
  </thead> 
  <tbody> 
    .....//datatables内容，此处省略 
  </tbody>

<input type="button" id="add" value="Add" />//添加按钮 
<input type="button" id="edit" value="Edit" />//编辑按钮

{ 
  UpdateTargetId = "d_Attributes", 
  OnSuccess = "dialogClose", 
  HttpMethod = "Post", 
})) 
  { 
    <table> 
      <tbody> 
        <tr>              
          <td>Name</td>

          </td> 
        </tr> 
      </tbody> 
    </table>

上面代码说明：这段代码主要分了两个部分，第一部分是jquery datatables的声明，

；第二部分是dialog的声明，以及操作所需要的action，此部分的操作选择ajax无刷新页面技术。所需js的代码：

<script type="text/javascript"> 
   function dialogClose() { 
     $("#e_Attributes").dialog("close"); 
   } 
   $("#e_Attributes").dialog({ 
     modal: true, 
     autoOpen: false, 
     show: { 
       effect: "blind", 
      duration: 1000 
     }, 
     hide: { 
       effect: "explode", 
       duration: 1000 
    }, 
    width: 400 
   }); 
    var editor; 
   $(function () { 
    //声明datatable 
     $("#gridtable").dataTable().fnDestroy(); 
     editor = $('#gridtable').dataTable({ 
      "bInfo":false, 
      "bServerSide": false, 
      'bPaginate': false,           //是否分页。 
       "bProcessing": false,          //当datatable获取数据时候是否显示正在处理提示信息。 
       'bFilter': false,            //是否使用内置的过滤功能。 
       'bLengthChange': false,         //是否允许用户自定义每页显示条数。 
       'sPaginationType': 'full_numbers',   //分页样式 
     }); 
    //单击，赋值，改样式 
    $("#gridtable tbody tr").click(function (e) { 
      if ($(this).hasClass('row_selected')) { 
        $(this).removeClass('row_selected'); 
        putNullValue() 
      } 
      else { 
        editor.$('tr.row_selected').removeClass('row_selected'); 
        $(this).addClass('row_selected'); 
        var aData = editor.fnGetData(this); 
        if (null != aData) { 
          putValue(aData); 
        } 
      } 
    }); 
    //双击 
    $("#gridtable tbody tr").dblclick(function () { 
      if ($(this).hasClass('row_selected')) { 
        //$(this).removeClass('row_selected'); 
      } 
      else { 
        editor.$('tr.row_selected').removeClass('row_selected'); 
        $(this).addClass('row_selected'); 
      } 
 
      var aData = editor.fnGetData(this); 
      if (null != aData) { 
        putValue(aData); 
      } 
 
      $("#hiddenValue").val("edit"); 
      $("#e_Attributes").dialog("open"); 
 
    }); 
    //添加 
    $("#add").click(function () { 
      editor.$('tr.row_selected').removeClass('row_selected'); 
      putNullValue(); 
 
      $("#hiddenValue").val("add"); 
      $("#e_Attributes").dialog("open"); 
    }); 
    //编辑 
    $("#edit").click(function () {

    //删除 
    $("#delete").click(function () {

      var productID = $("#productID").val(); 
      if (productAttributeID != null && productAttributeID != "") {

            url: "@Url.Action("DeleteAttribute", "Product")", 
            data: { ProductID: productID, ProductAttributeID: productAttributeID },//参数名要和Action 中的参数名相同 
            dataType: "html", 
            cache: false, 
            success: function (result) { 
              $("#d_Attributes").html(result); 
              $("#productAttributeID").val(null); 
            } 
          }); 
        } 
      } 
    }); 
 
    //赋空值，并去除input-validation-error样式（此样式不管有无，均可去除，所以不用判断了） 
    function putNullValue() { 
      。。。。。。／／此处省略 
    } 
    //赋值 
    function putValue(aData) { 
     。。。。。。//此处省略 
    } 
  }); 
 
  $.ajaxSetup({ cache: false });

4、分页实现

引入CSS文件和JS文件

<style type="text/css" title="currentStyle"> 
    @import "DataTables-1.8.1/media/css/demo_page.css"; 
    @import "DataTables-1.8.1/media/css/demo_table.css"; 
    @import "DataTables-1.8.1/media/css/demo_table_jui.css"; 
</style> 
<script type="text/javascript" language="javascript" src="DataTables-1.8.1/media/js/jquery.js"></script> 
<script type="text/javascript" language="javascript" src="DataTables-1.8.1/media/js/jquery.dataTables.js"></script> 
  
 -------------------------------------------------------------------------- 
  
-----------最简单的方式： 
 $(document).ready(function() { 
 $("#example").dataTable(); 
}); 
  
----------也可以自己定义各属性： 
<script type="text/javascript" language="javascript"> 
    $(document).ready(function() { 
      $("#example").dataTable({ 
//        "bPaginate": true, //开关，是否显示分页器 
//        "bInfo": true, //开关，是否显示表格的一些信息 
//        "bFilter": true, //开关，是否启用客户端过滤器 
//        "sDom": "<>lfrtip<>", 
//        "bAutoWith": false, 
//        "bDeferRender": false, 
//        "bJQueryUI": false, //开关，是否启用JQueryUI风格 
//        "bLengthChange": true, //开关，是否显示每页大小的下拉框 
//        "bProcessing": true, 
//        "bScrollInfinite": false, 
//        "sScrollY": "800px", //是否开启垂直滚动，以及指定滚动区域大小,可设值：'disabled','2000px' 
//        "bSort": true, //开关，是否启用各列具有按列排序的功能 
//        "bSortClasses": true, 
//        "bStateSave": false, //开关，是否打开客户端状态记录功能。这个数据是记录在cookies中的，打开了这个记录后，即使刷新一次页面，或重新打开浏览器，之前的状态都是保存下来的- ------当值为true时aoColumnDefs不能隐藏列 
//        "sScrollX": "50%", //是否开启水平滚动，以及指定滚动区域大小,可设值：'disabled','2000%' 
//        "aaSorting": [[0, "asc"]], 
//        "aoColumnDefs": [{ "bVisible": false, "aTargets": [0]}]//隐藏列 
//        "sDom": '<"H"if>t<"F"if>', 
        "bAutoWidth": false, //自适应宽度 
        "aaSorting": [[1, "asc"]], 
        "sPaginationType": "full_numbers", 
        "oLanguage": { 
          "sProcessing": "正在加载中......", 
          "sLengthMenu": "每页显示 _MENU_ 条记录", 
          "sZeroRecords": "对不起，查询不到相关数据！", 
          "sEmptyTable": "表中无数据存在！", 
          "sInfo": "当前显示 _START_ 到 _END_ 条，共 _TOTAL_ 条记录", 
          "sInfoFiltered": "数据表中共为 _MAX_ 条记录", 
          "sSearch": "搜索", 
          "oPaginate": { 
            "sFirst": "首页", 
            "sPrevious": "上一页", 
            "sNext": "下一页", 
            "sLast": "末页" 
          } 
        } //多语言配置 
  
      }); 
    }); 
  </script>

对于 dataTables 来说，表格必须通过 thead 和 tbody 进行说明，如下所示，

<table cellpadding="0" cellspacing="0" border="0" class="display" id="example"> 
    <thead> 
      <tr> 
        <th> 
          Rendering engine 
        </th> 
        <th> 
          Browser 
        </th> 
        <th> 
          Platform(s) 
        </th> 
        <th> 
          Engine version 
        </th> 
        <th> 
          CSS grade 
        </th> 
      </tr> 
    </thead> 
    <tbody> 
      <tr class="odd gradeX"> 
        <td> 
          Trident 
        </td> 
        <td> 
          Internet Explorer 4.0 
        </td> 
        <td> 
          Win 95+ 
        </td> 
        <td class="center"> 
          4 
        </td> 
        <td class="center"> 
          X 
        </td> 
      </tr>

如果没有 thead 将会报错。

bPaginate: 是否分页，默认为 true，分页
iDisplayLength : 每页的行数，每页默认数量:10
sPaginationType: 分页样式，支持两种内置方式，two_button 和 full_numbers, 默认使用 two_button。
bLengthChange : 是否允许用户通过一个下拉列表来选择分页后每页的行数。行数为 10，25，50，100。这个设置需要 bPaginate 支持。默认为 true。
bFilter: 启用或禁止数据过滤，默认为 true。注意，如果使用过滤功能，但是希望关闭默认的过滤输入框，应使用 sDom
bInfo: 允许或者禁止表信息的显示，默认为 true，显示信息。

最为简单的使用方式，就是零配置的方式。

/*
 * Example init
 */
$(document).ready(function(){
  $('#example').dataTable()
