如何解决php中的Ajax无法正常工作
| / * 在以下代码中，有一个下拉列表，必须在每次发生更改时调用该函数。 该函数名称为TotalCountsOfPL（）。 下拉列表是name，Id是\“ sltLeaveType \”; 在名为textbox（AjxSelectedLeaveType）的函数之后，应使用下拉列表的选定值填充。 并且应使用数据库已获取的计数填充文本框（AjxTakenLeave）。 * / 我在项目中使用了Ajax概念。 那就是在Dropdownlist的更改上，我正在调用function（method）。但这是行不通的。 表示当我选择dropdownList的内容时，应该在名为的文本字段中显示所选数据（选项） 我的html文件是 我在项目中使用了Ajax概念。 那就是在Dropdownlist的更改上，我正在调用function（method）。但这是行不通的。 我的html文件是<html>

}
$result = mysql_query($query);
echo \"document.getElementById(\"AjxTakenLeave\").innerHTML={$result}\";
mysql_close($con);
?>
解决方法
您正在将PHP与JavaScript混合使用。例如：
if(str!=\"\")
{
$_SESSION[\"mySessionVariable\"] = str;
document.getElementById(\"AjxSelectedLeaveType\").innerHTML=str;
}
$_SESSION
document.getElementById
<html>
<head>
<script>
function TotalCountsOfPL(str)
{
if(iset(session_unregister(\"mySessionVariable\")))
{
session_destroy();
};
session_start();
session_register(\"mySessionVariable\");
if(str!=\"\")
{
$_SESSION[\"mySessionVariable\"] = str;
document.getElementById(\"AjxSelectedLeaveType\").innerHTML=str;
}
if (str==\"\")
{
document.getElementById(\"AjxTakenLeave\").innerHTML=\"\";
//document.getElementById(\"AjxLeaveType\").innerHTML=\"\";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+,Firefox,Chrome,Opera,Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6,IE5
xmlhttp=new ActiveXObject(\"Microsoft.XMLHTTP\");

{
if (xmlhttp.readyState==4 && xmlhttp.status==200)

xmlhttp.open(\"POST\",\"getPLCount.php\",true);
xmlhttp.send();
