Here my ajax code:

function GetXmlHttpObject(handler)
{
var objXMLHttp=null
if (window.XMLHttpRequest)
{
objXMLHttp=new XMLHttpRequest()
}
else if (window.ActiveXObject)
{
objXMLHttp=new ActiveXObject("Microsoft.XMLHTTP")
}
return objXMLHttp
}

function stateChanged()
{
if (xmlHttp.readyState==4 || xmlHttp.readyState=="complete")
{
document.getElementById("txtResult").innerHTML=xmlHttp.responseText
}
else
{
//alert(xmlHttp.status);
}
}

function htmlData(url, qStr)
{
if (url.length==0)
{
document.getElementById("txtResult").innerHTML="";
return;
}
xmlHttp=GetXmlHttpObject()
if (xmlHttp==null)
{
alert ("Browser does not support HTTP Request");
return;
}

url=url+"?"+qStr;
url=url+"&sid="+Math.random();
xmlHttp.onreadystatechange=stateChanged;
xmlHttp.open("GET",url,true) ;
xmlHttp.send(null);
}

如何在分页的第一页后获取选定的类别 ID？

  • 使用 AJAX 调用发布它并返回它
  • 将其存储在本地 JS 变量中
  • 将其添加到 URL

您似乎知道$_GET['p']获取查询字符串中传递的 'p' 参数的值。好在$_REQUEST['category']做同样的事情。（技术上$_REQUEST检查了和中$_POST的所有内容）。$_GET$_COOKIE

因此，如果您没有在查询字符串中设置“类别”，那么它不会在您的代码中包含任何内容。

  1. 你应该添加 ? category=XXX &sid=RAND... 到您的网址
  2. 更好的使用$category = isset($_GET['category']) ? (int)$_GET['category'] : 0;

你category在请求中通过了吗？您没有向我们提供该信息（qstrjavascript 中的值是什么？），但我猜不是。

您还将它直接传递到 SQL 查询中，这使您可以进行注入。
你应该用它mysql_escape_string()来解决这个问题。
