我不确定这是否与 ajax 调用有关。我对 Ajax 很陌生,所以我怀疑这是原因。
我运行以下 javascript:
function GetXmlHttpObject() {
"use strict";
var objXMLHttp = null;
if (window.XMLHttpRequest) {
objXMLHttp = new XMLHttpRequest();
} else if (window.ActiveXObject) {
objXMLHttp = new window.ActiveXObject("Microsoft.XMLHTTP");
}
return objXMLHttp;
}
function delete_director(i) {
"use strict";
var r, url;
r = window.confirm("Are you sure you want to disable this director");
url = "ajax.php?task=director&event=delete&UserId=" + i;
if (r === true) {
mdata = new GetXmlHttpObject();
if (mdata === null) {
alert("Browser does not support HTTP Request");
return;
}
mdata.open("GET", url, true);
mdata.send(null);
}
}
这会调用以下 php 函数:
function deletedirector()
{
$UserId=mysql_real_escape_string($_GET['UserId']);
$query = "update tbl_users set IsDisabled='1' where UserId=".$UserId;
$result = mysql_query($query) OR die('Cannot perform query!');
if ($result) {
error_log("a");
?><script type="text/javascript">window.location='index.php?task=director&success=Director Successfully Deleted.'</script><?
} else {
error_log("b");
?><script type="text/javascript">window.location='index.php?task=director&error=Director Deletion Failed.'</script><?
}
}
db 显示director 已被删除,错误日志中显示“a”,但window.location 永远不会触发。
用户体验是浏览器提示确认,然后 - 什么都没有。JavaScript 控制台现在显示错误。
有任何想法吗?
