Using AJAX to implement no-refresh paging in thinkphp

Create a new AjaxPage.class.php in the lib\org\util\ directory of the thinkphp directory and write the contents:

The controller writes the following:

<?php
Class Useraction extends action{
Public Function User () {
Import ("ORG. Util.ajaxpage ")//Import paging class Note the import is the Ajaxpage class that you write
$credit = M (' user ');
$count = $credit->count (); Calculate the number of records
$limitRows = 5; Set the number of records per page

$p = new Ajaxpage ($count, $limitRows, "user"); The third parameter is the name of the AJAX function that you need to invoke to change the page
$limit _value = $p->firstrow. "," . $p->listrows;

$data = $credit->order (' id desc ')->limit ($limit _value)->select (); Querying data
$page = $p->show (); Generate paging information, where AJAX connections are generated

$this->assign (' list ', $data);
$this->assign (' page ', $page);
$this->display ();

}
}

?>

The template file is as follows:

<title>ajax No Refresh page </title>
<script type= "Text/javascript" src= ". /public/jquery-1.7.2.min.js "></script>
<script type= "Text/javascript" >
Functions User (ID) {//user function name must be the same as the third parameter in the action above
var id = ID;
$.get (' User/user ', {' P ': id}, function (data) {//) send information to the User method in Useraction using the Get method
$ ("#user"). ReplaceWith ("<div id= ' user ' >" +data+ "</div>"); User must be consistent with the TPL
});
}

</script>

<body>
<div id= ' user ' > <!--here the user is the same as the test in JS below--
<volist id= ' list ' name= ' list ' > <!--content Output--
<{$list. id}>&nbsp;&nbsp;<{$list .username}><br/>
</volist>
<{$page}> <!--paging output--
</div>

</body>
