Jquery DataTable基本使用
原文:https://www.cnblogs.com/xiashengwang/p/8087181.html
1,首先需要引用下面两个文件
<link rel="stylesheet" href="https://cdn.datatables.net/1.10.16/css/jquery.dataTables.min.css" />
<script src="https://cdn.datatables.net/1.10.16/js/jquery.dataTables.min.js"></script>
2,DataTable支持的数据类型
https://www.datatables.net/manual/data/
2.1 数组
vardata = [ [ "Tiger Nixon", "System Architect", "Edinburgh", "5421", "2011/04/25", "$3,120" ], [ "Garrett Winters", "Director", "Edinburgh", "8422", "2011/07/25", "$5,300" ] ]
2.2 对象
[ { "name": "Tiger Nixon", "position": "System Architect", "salary": "$3,120", "start_date": "2011/04/25", "office": "Edinburgh", "extn": "5421" }, { "name": "Garrett Winters", "position": "Director", "salary": "$5,300", "start_date": "2011/07/25", "office": "Edinburgh", "extn": "8422" } ]
2.3 自定义实例(本质和2.2一样)
functionEmployee ( name, position, salary, office ) { this.name = name; this.position = position; this.salary = salary; this._office = office; this.office = function() { returnthis._office; } };$('#example').DataTable( {
data: [
newEmployee( "Tiger Nixon", "System Architect", "$3,120", "Edinburgh"),
newEmployee( "Garrett Winters", "Director", "$5,300", "Edinburgh")
],
columns: [
{ data: 'name'},
{ data: 'salary'},
{ data: 'office'},
{ data: 'position'}
]
} );
2.4 datatable的数据来源
1)DOM
如果没有指定data,ajax选项,则DataTable会将当前table的html标签上内容转换成对应的数据(Array数据形式)。
2)Html5
Data-* 标签上可以指定不同的值,用于排序和查找,td内部标签的值对应当前单元格的数据。
<td data-search="21st November 2016 21/11/2016" data-order="1479686400"> 21st November 2016 </td>
3)javascript
通过data配置,指定数据源。可以通过DataTables API row.add() row().remove()操作行数据。
4)Ajax
通过服务器端分页的方式,取得数据。返回的数据只能是json数组或对象(上面的2.1和2.2).
3,有两种分页方式
3.1 客户端分页
这种方式,代码最简单,整个数据量在10000条以内可以考虑。假设已经有了下面的table:
<table id="table1" class="table table-condensed"> <thead> <tr> <th>ID</th> <th>Name</th> <th>Score</th> </tr> </thead> <tbody> <tr> <td>001</td> <td>zhang</td> <td>98</td> </tr> <tr> <td>002</td> <td>wang</td> <td>99</td> </tr> </tbody> </table>
简单调用一句话(使用默认设置),就可以使table具有排序,查找,分页的基本功能。
$(function () { $("#table1").DataTable({ }); });
3.2 服务器端分页
这种方式针对大数据量的table(10万条以上),每次只读取当前的一页数据,分页在后台做。代码相对复杂,不过页面响应更快,
服务器端的分页一般要求我们先定义thead表头,tbody可以不写。
4,配置参数
这些配置参数可以通过javascript进行设置,也可以直接用HTML5标签data-* 的方式写在table的标签中。

8,其他
8.1 重新加载数据
第二个参数为false的话,会保持当前的选中页。
vartable = $('#example').DataTable();
table.ajax.reload( function( json ) {
$(</span>'#myInput'<span style="color: #000000;">).val( json.lastInput );
} , true);
8.2 改变url,再加载
table.ajax.url( 'newData.json').load();
8.3 获取服务器返回的json数据
vartable = $('#example').DataTable();
table.on( 'xhr', function() {
varjson </span>=<span style="color: #000000;"> table.ajax.json();
alert( json.data.length </span>+' row(s) were loaded'<span style="color: #000000;">);
} );
