使用JavaScript+XML实现分页

代码如下：
<xml id="users"><userGroup> <user> <userid>user 1</userid> <name>name 1</name> </user> <user> <userid>user 2</userid> <name>name 2</name> </user> <user> <userid>user 3</userid> <name>name 3</name> </user> <user> <userid>user 4</userid> <name>name 4</name> </user> <user> <userid>user 5</userid> <name>name 5</name> </user> <user> <userid>user 6</userid> <name>name 7</name> </user> <user> <userid>user 7</userid> <name>name 7</name> </user> <user> <userid>user 8</userid> <name>name 8</name> </user> <user> <userid>user 9</userid> <name>name 9</name> </user></userGroup></xml><table id="datatable" datasrc="#users" DATAPAGESIZE="3" width="400" border="1"><tr> <td><span datafld="userid"></span></td> <td><span datafld="name"></span></td></tr></table><button onclick="document.all.datatable.firstPage()">First Page</button><button onclick="document.all.datatable.previousPage()">Previous Page</button><button onclick="document.all.datatable.nextPage()">Next Page</button><button onclick="document.all.datatable.lastPage()">Last Page</button>
