Detailed explanation of the usage of jQuery plug-in datatables and how to implement paging code

DataTables is a jQuery table plug-in.

Explanation with examples

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 double-clicked row changes color. 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. Coding:
Attributes//Name

 <table id="gridtable" class="gridtable">//声明jquery datatables 
   <thead> 
     <tr> 
       <th>Name 
       </th> 
       <th>Value 
       </th> 
       <th>DisplayOrder 
      </th> 
    </tr> 
  </thead> 
  <tbody> 
    .....//datatables内容，此处省略 
  </tbody> 
</table> 
<input type="button" id="add" value="Add" />//添加按钮 
<input type="button" id="edit" value="Edit" />//编辑按钮 
<input type="button" id="delete" value="Delete" />//删除按钮 
 
 
<p id="e_Attributes">//声明dialog,异步更新 
  @using (Ajax.BeginForm("Update", "Product", new AjaxOptions 
{ 
  UpdateTargetId = "d_Attributes", 
  OnSuccess = "dialogClose", 
  HttpMethod = "Post", 
})) 
  { 
    <table> 
      <tbody> 
        <tr>              
          <td>Name</td> 
          <td> 
           <input id="name" name="Name" type="text" style="width:250px" class="required"/>*</td> 
        </tr> 
        <tr> 
          <td>Value</td> 
          <td> 
            <input id="value" name="Value" type="text" style="width:250px" class="required"/>*</td> 
        </tr> 
        <tr>   
         <td>DisplayOrder</td> 
          <td> 
            <input id="displayOrder" name="DisplayOrder" type="text" style="width:128px" class="required"/>*</td> 
        </tr> 
        <tr> 
          <td> 
            <input id="submit" type="submit" name="submit" value="Submit" /> 
            <input id="hiddenValue" type="hidden" name="hiddenValue" /> 
          </td> 
        </tr> 
      </tbody> 
    </table> 
  } 
</p>

Description of the above code: This code is mainly divided into two parts. The first part is The declaration of jquery datatables, 7255ed4a65b8a0103bb60d0ff43be0fe; the second part is the declaration of the dialog and the actions required for the operation. For this part of the operation, select the ajax non-refresh page technology. Required js code:

<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 = $(&#39;#gridtable&#39;).dataTable({ 
      "bInfo":false, 
      "bServerSide": false, 
      &#39;bPaginate&#39;: 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。 
       &#39;bFilter&#39;: false,            //是否使用内置的过滤功能。 
       &#39;bLengthChange&#39;: false,         //是否允许用户自定义每页显示条数。 
       &#39;sPaginationType&#39;: &#39;full_numbers&#39;,   //分页样式 
     }); 
    //单击，赋值，改样式 
    $("#gridtable tbody tr").click(function (e) { 
      if ($(this).hasClass(&#39;row_selected&#39;)) { 
        $(this).removeClass(&#39;row_selected&#39;); 
        putNullValue() 
      } 
      else { 
        editor.$(&#39;tr.row_selected&#39;).removeClass(&#39;row_selected&#39;); 
        $(this).addClass(&#39;row_selected&#39;); 
        var aData = editor.fnGetData(this); 
        if (null != aData) { 
          putValue(aData); 
        } 
      } 
    }); 
    //双击 
    $("#gridtable tbody tr").dblclick(function () { 
      if ($(this).hasClass(&#39;row_selected&#39;)) { 
        //$(this).removeClass(&#39;row_selected&#39;); 
      } 
      else { 
        editor.$(&#39;tr.row_selected&#39;).removeClass(&#39;row_selected&#39;); 
        $(this).addClass(&#39;row_selected&#39;); 
      } 
 
      var aData = editor.fnGetData(this); 
      if (null != aData) { 
        putValue(aData); 
      } 
 
      $("#hiddenValue").val("edit"); 
      $("#e_Attributes").dialog("open"); 
 
    }); 
    //添加 
    $("#add").click(function () { 
      editor.$(&#39;tr.row_selected&#39;).removeClass(&#39;row_selected&#39;); 
      putNullValue(); 
 
      $("#hiddenValue").val("add"); 
      $("#e_Attributes").dialog("open"); 
    }); 
    //编辑 
    $("#edit").click(function () { 
       var productAttributeID = $("#productAttributeID").val(); 
      if (productAttributeID != "" && productAttributeID != null) { 
        $("#hiddenValue").val("edit"); 
        $("#e_Attributes").dialog("open"); 
      } 
 
    }); 
    //删除 
    $("#delete").click(function () { 
      var productAttributeID = $("#productAttributeID").val(); 
      var productID = $("#productID").val(); 
      if (productAttributeID != null && productAttributeID != "") { 
        if (confirm("Delete?")) { 
          $.ajax({ 
            type: "GET", 
            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 }); 
</script>

Description of the above code: This code is the declaration of dialog, and the declaration of datatables is operated by add, edit, and delete.

4. Paging implementation

Introducing CSS files and JS files

<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：&#39;disabled&#39;,&#39;2000px&#39; 
//        "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：&#39;disabled&#39;,&#39;2000%&#39; 
//        "aaSorting": [[0, "asc"]], 
//        "aoColumnDefs": [{ "bVisible": false, "aTargets": [0]}]//隐藏列 
//        "sDom": &#39;<"H"if>t<"F"if>&#39;, 
        "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>

For dataTables, tables It must be explained through thead and tbody, as shown below,

<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>

If there is no thead, an error will be reported.

• bPaginate: Whether to paginate, the default is true, pagination

• iDisplayLength: Number of lines per page, default number per page: 10

• sPaginationType: Pagination style, supports two built-in methods , two_button and full_numbers, two_button is used by default.

• bLengthChange: Whether to allow the user to select the number of rows per page after paging through a drop-down list. The number of rows is 10, 25, 50, 100. This setting requires bPaginate support. Defaults to true.

• bFilter: Enable or disable data filtering, the default is true. Note that if you use the filtering function but want to turn off the default filtering input box, you should use sDom

• bInfo: to allow or prohibit table information The display, the default is true, displays information.

#The simplest way to use it is zero configuration.

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