Question

我有一个页面使用JqueryUI-Mobile（更具体地说是listview）以及带有一些Ajax代码的PHP。

页面加载从MySQL DB生成的列表，然后我希望该列表刷新自己，而不刷新页面（为了更好的用户体验）。

目前，我可以使用.load来刷新数据，但我有一个奇怪的副作用。

在页面加载时，它会正确呈现。我猜是因为它首先加载了正确的方法。但是，一旦ajax .load调用进来。它会将整个页面加载到div内部，而不仅仅是div内部的内容。谁能看到我做错了什么？或者如果我不是没有正确地做到这一点，建议采用正确的方法吗？

这是我的代码。

<?php
session_start();
if(isset($_SESSION['username']))
{

}
else
{
$_SESSION['error']="You are logged in.";
header('Location: index.php');
    exit;
}

Answer 1

我忽略了.load的关键要求。我没有指定我正在加载的页面上的内容，因此它正在加载整个页面。

function myFunction(){
    $(".ui-content").load("thispage.php");

已更改为

function myFunction(){
    $(".ui-content").load("thispage.php .ui-content");

这解决了这个问题。

Ajax刷新整个页面的问题
