一、DataTables
个人觉得学习一门新的插件或者技术时候，官方文档是最根本的，入门最快的地方，但是有时候看完官方文档，一步步的动手写例子，总会出现各种莫名其妙的错误，需要我们很好的进行研究出错的地方。
官方网站（中文）：http://datatables.club/
官方网站：https://www.datatables.net/
二、简单的例子
怎样简单地使用DataTables？使用下方简单的几行代码，一个方法初始化table。
$(document).ready(function(){ $(‘#myTable‘).DataTable(); });
开始使用DataTables很简单，只需要引入两个文件， 一个css样式文件和DataTables本身的脚本文件。在DataTables CDN上，可以使用下面这两个文件：
js文件 //cdn.datatables.net/1.10.13/js/jquery.dataTables.min.js
css文件 //cdn.datatables.net/1.10.13/css/jquery.dataTables.min.css
在你的项目中使用 DataTables，只需要引入三个文件即可，jQuery库，一个DT的核心js文件和一个DT的css文件， 完成以以下三步即可看到如下效果：
1、例子1：
(1)使用的是：Hbuilder
(2)项目结构：
(3)index.html代码
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript"> $(document).ready(function() { $(‘#example‘).DataTable(); }); </script> </head> <body> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tfoot> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
(4)效果：
2、例子2:（PS：还是纯粹的前端静态页面）
(1)结构和工具见例子1
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript"> $(document).ready(function() { $(‘#example‘).DataTable(); }); </script> </head> <body> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tbody> <tr> <th>bob</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> </tr> <tr> <th>JIM</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> </tr> <tr> <th>Jack</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> </tr> <tr> <th>qiao</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> <th>123</th> </tr> </tbody> <tfoot> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
(2)效果：
说明：search的输入框是对所有属性的全部搜索，并显示搜索结果，最重要的是：这个搜索与表格进行了数据的双向绑定，可以实时进行更新。
重要：DataTables已经读取几乎任何JSON数据源，可以通过ajax.datatables读数据的能力已经从几乎任何JSON数据源可以通过Ajax读取数据的能力。

通过使用 columns.dataDT 选项用于告诉Datatables找到每一列的数据源对象中对应的属性。

对比数据源是数组（左边）和对象（右边）格式的不同
（3）index_02.html内容
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript" language="javascript" class="init"> $(document).ready(function() { $(‘#example‘).DataTable({ "ajax": "data/objects.txt", //data:name指的是引用data中name的属性。columns中每一个data顺序就是表格内容的真正顺序 "columns": [{ "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "extn" }, { "data": "start_date" }, { "data": "salary" }] }); }); </script> </head> <body> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tfoot> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
（4）效果
5、例子5:（PS：使用ajax，不指定数据源属性）
当从 Ajax 源加载数据，在默认情况下，数据表将寻找要使用返回的对象的数据参数中的数据。
dataSrc有许多用法如下：
- 作为一个字符串，如
dataSrc: ‘myData‘ - 为空字符串，如
dataSrc:""，下面的例子展示的是这个用法 - 作为一个方法，如
dataSrc： function(json) {}（您可以从 XML 转换到一个 Javascript 对象）
$(document).ready(function() { $(‘#example‘).dataTable( { "ajax": { "url": "data/objects_root_array.txt", //默认为data,这里定义为空，则只需要传不带属性的数据 "dataSrc": "" }, "columns": [ { "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "extn" }, { "data": "start_date" }, { "data": "salary" } ] } ); } );
效果：如上图例子所示
6、例子6:（PS：动态显示和隐藏列）
这个例子演示了 column().visible()方法来隐藏显示列，通过点击列按钮动态切换。
（1）项目结构（PS：新增加的index_03.css）
（2）index_03.css文件
/*表格字体*/ body { font: 90%/1.45em "Helvetica Neue", HelveticaNeue, Arial, Helvetica, sans-serif; margin: 0; padding: 0; color: #333; background-color: #fff; } /*column的字体颜色和小手*/ a { cursor: pointer; color: #3174c7; text-decoration: none; }
（3）objects.txt文件内容参考上的例子内容
（4）index_03.html文件
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--自己样式--> <link rel="stylesheet" type="text/css" href="css/index_03.css"/> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript" language="javascript" class="init"> $(document).ready(function() { var table = $("#example").DataTable({ "ajax": "data/objects.txt", "columns": [{ "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "extn" }, { "data": "start_date" }, { "data": "salary" }], //展示高度 "scrollY": "300px", //显示多少行去掉 "paging": false }); //显示和隐藏 $(‘a.toggle-vis‘).on(‘click‘, function(e) { e.preventDefault(); // Get the column API object var column = table.column($(this).attr(‘data-column‘)); // Toggle the visibility column.visible(!column.visible()); }); }); </script> </head> <body> <!--索引--> <div class="demo-html"> <div> Toggle column: <a class="toggle-vis" data-column="0">Name</a> - <a class="toggle-vis" data-column="1">Position</a> - <a class="toggle-vis" data-column="2">Office</a> - <a class="toggle-vis" data-column="3">Age</a> - <a class="toggle-vis" data-column="4">Start date</a> - <a class="toggle-vis" data-column="5">Salary</a> </div> </div> <!--正式table--> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tfoot> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
（5）效果所示
7、例子7:（PS：在回调方法中使用api）
有时候希望给表格绑定的数据行绑定一些事件，这个时候你需要用到 initCompleteDT 、rowCallback 这些回调方法，下面的例子演示了，当表格加载完后给表格的td绑定点击事件，取到值后进行搜索
（1）项目结构
（2）index_03.css文件参照上一个例子
（3）objects.txt文件参照上面的例子
（4）index_04.html文件
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--自己样式--> <link rel="stylesheet" type="text/css" href="css/index_03.css"/> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript" language="javascript" class="init"> $(document).ready(function() { var table = $("#example").DataTable({ "ajax": "data/objects.txt", "columns": [{ "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "extn" }, { "data": "start_date" }, { "data": "salary" }], //展示高度 // "scrollY": "300px", //显示多少行去掉 // "paging": false //右下角的分页 "initComplete":function(){ var api=this.api(); api.$("td").click(function(){ api.search(this.innerHTML).draw(); }) } }); //显示和隐藏哪一列 $(‘a.toggle-vis‘).on(‘click‘, function(e) { e.preventDefault(); // Get the column API object var column = table.column($(this).attr(‘data-column‘)); // Toggle the visibility column.visible(!column.visible()); }); }); </script> </head> <body> <!--索引--> <div class="demo-html"> <div> Toggle column: <a class="toggle-vis" data-column="0">Name</a> - <a class="toggle-vis" data-column="1">Position</a> - <a class="toggle-vis" data-column="2">Office</a> - <a class="toggle-vis" data-column="3">Age</a> - <a class="toggle-vis" data-column="4">Start date</a> - <a class="toggle-vis" data-column="5">Salary</a> </div> </div> <!--正式table--> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </thead> <tfoot> <tr> <th>Name</th> <th>Position</th> <th>Office</th> <th>Extn.</th> <th>Start date</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
（5）效果如图
三、稍微复杂的例子
8、例子8:（PS：显示行的附加信息）
使用Ajax调用服务器来获得行的附加信息。
（1）项目结构
（2）index_03.css
/*表格字体*/ body { font: 90%/1.45em "Helvetica Neue", HelveticaNeue, Arial, Helvetica, sans-serif; margin: 0; padding: 0; color: #333; background-color: #fff; } /*column的字体颜色和小手*/ a { cursor: pointer; color: #3174c7; text-decoration: none; } /*显示显示和影藏按钮*/ td.details-control { background: url(../img/details_open.png) no-repeat center center; cursor: pointer; } tr.shown td.details-control { background: url(../img/details_close.png) no-repeat center center; }
（3）objects.js文件和objects.txt文件内容一样，你使用js和txt是一样的，只要里面存的数据是对的就行
（4）添加img两个图片
（5）index_05.htm
<!DOCTYPE html> <html> <head> <meta charset="utf-8" /> <title>DataTables简单用例</title> <!--自己样式--> <link rel="stylesheet" type="text/css" href="css/index_03.css" /> <!--样式--> <link rel="stylesheet" type="text/css" href="DataTables-1.10.13/media/css/jquery.dataTables.css"> <!-- jQuery --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.js"></script> <!-- DataTables --> <script type="text/javascript" charset="utf8" src="DataTables-1.10.13/media/js/jquery.dataTables.js"></script> <script type="text/javascript" language="javascript" class="init"> //格式函数 function format(d) { // `d` is the original data object for the row return ‘<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">‘ + ‘<tr>‘ + ‘<td>Full name:</td>‘ + ‘<td>‘ + d.name + ‘</td>‘ + ‘</tr>‘ + ‘<tr>‘ + ‘<td>Extension number:</td>‘ + ‘<td>‘ + d.extn + ‘</td>‘ + ‘</tr>‘ + ‘<tr>‘ + ‘<td>Extra info:</td>‘ + ‘<td>And any further details here (images etc)...</td>‘ + ‘</tr>‘ + ‘</table>‘; } //ready $(document).ready(function() { var table = $("#example").DataTable({ "ajax": "/DataTables_simple/data/objects.js", "columns": [{ "className": ‘details-control‘, "orderable": false, "data": null, "defaultContent": ‘‘ }, { "data": "name" }, { "data": "position" }, { "data": "office" }, { "data": "salary" }], //默认显示是升序 "order": [ [1, ‘asc‘] ], //展示高度 // "scrollY": "300px", //显示多少行去掉 // "paging": false //右下角的分页 "initComplete": function() { var api = this.api(); api.$("td").click(function() { api.search(this.innerHTML).draw(); }) } }); //显示和隐藏哪一列 $(‘a.toggle-vis‘).on(‘click‘, function(e) { e.preventDefault(); // Get the column API object var column = table.column($(this).attr(‘data-column‘)); // Toggle the visibility column.visible(!column.visible()); }); //按钮显示和隐藏 Add event listener for opening and closing details $(‘#example tbody‘).on(‘click‘, ‘td.details-control‘, function() { var tr = $(this).closest(‘tr‘); var row = table.row(tr); if(row.child.isShown()) { // This row is already open - close it row.child.hide(); tr.removeClass(‘shown‘); } else { // Open this row row.child(format(row.data())).show(); tr.addClass(‘shown‘); } }); }); </script> </head> <body> <!--索引--> <div class="demo-html"> <div> Toggle column: <a class="toggle-vis" data-column="1">Name</a> - <a class="toggle-vis" data-column="2">Position</a> - <a class="toggle-vis" data-column="3">Office</a> - <a class="toggle-vis" data-column="4">Salary</a> </div> </div> <!--正式table--> <table id="example" class="display" cellspacing="0" width="100%"> <thead> <tr> <th></th> <th>Name</th> <th>Position</th> <th>Office</th> <th>Salary</th> </tr> </thead> <tfoot> <tr> <th></th> <th>Name</th> <th>Position</th> <th>Office</th> <th>Salary</th> </tr> </tfoot> </table> </body> </html>
（6）效果如图
三、报错问题的解决
会出现这种错误，是对数据进行解析出错，需要你检查地方如下所示
1、数据的路径容易错，很容易错，
2、数据解析的方式容易错，与txt或者js里存的数据格式要对应上
