【求助】php ajax 無刷新返回表單值到當前頁面
function send(gettype)
{
var ajaxdata = “”
wenben = $(‘#wenben’).val();
ajaxdata += “wenben=”+wenben;
$.ajax({
type: “post”,
url : “tj.php”,
data: ajaxdata,
success: function(html){
$(“.getcode”).css(“display”,”block”);
$(“#codebox”).val(html);
}
});
}
我測試了你的代碼可以正常運行啊
php怎麼實現無刷新分頁效果
php+ajax實現無刷新分頁實現方法具體如下：
limit 偏移量，長度;
limit 0,7; 第一頁
limit 7,7; 第二頁
limit 14,7; 第三頁
每頁信息條數：7
信息總條數：select count(*) from table
信息總頁數：ceil向上取整(總條數/每頁條數)
1、分頁類具體使用
?php
class Pagination {
private $total; //數據表中總記錄數
private $listRows; //每頁顯示行數
private $limit; //mysql 數據庫的limit
private $uri; //分頁信息前面的uri地址
private $pageNum; //頁數
private $config = array(‘header’ = “個記錄”, “prev” = “【上一頁】”, “next” = “【下一頁】”, “first” = “【首 頁】”, “last” = “【尾 頁】”);
private $listNum = 8;
/*
* $total 當前信息總條數
* $listRows 每頁顯示的條數
* $pa 下面的page
http://網址/index.php?page=5
*/
public function __construct($total, $listRows = 10, $pa = “”) {
$this-total = $total;
$this-listRows = $listRows;
$this-uri = $this-getUri($pa);
$this-page = !empty($_GET[“page”]) ? $_GET[“page”] : 1;//不傳入page，則默認顯示首頁
$this-pageNum = ceil($this-total / $this-listRows);
$this-limit = $this-setLimit();
}
//設置每頁顯示的條數
private function setLimit() {
return “Limit ” . ($this-page – 1) * $this-listRows . “, {$this-listRows}”;
}
//獲得URL地址
private function getUri($pa) {
$url = $_SERVER[“REQUEST_URI”] . (strpos($_SERVER[“REQUEST_URI”], ‘?’) ? ” : “?”) . $pa;
$parse = parse_url($url);
if (isset($parse[“query”])) {
parse_str($parse[‘query’], $params);
unset($params[“page”]);
$url = $parse[‘path’] . ‘?’ . http_build_query($params);
}
return $url;
}
//魔術方法，
public function __get($args) {
if ($args == “limit”)
return $this-limit;
else
return null;
}
//頁面開始的條數
private function start() {
if ($this-total == 0)
return 0;
else

//頁面結束的條數

}

誰給我講下ajax+php無刷新分頁原理
ajax 是一個js腳本。或者用jquery裏面的ajax
如果你要驗證用戶名。你可以在你的input 屬性裏面加上 onchange=「調用函數」
調用函數就是ajax的代碼。
ajax是這樣完成工作的，
首先發送請求到你指定的頁面比如abc.php（附帶你設置的post或者get），
abc.php響應成功後，執行它裏面的代碼去處理你傳遞過來的參數。如果存在這個用戶。然後返回一個值或者函數 如果不存在也會返回一個值或者函數，你要自己去設置。
然後ajax把這個返回的值或者函數進行處理，比如顯示它，或者調用函數禁用提交按鈕。
