Ajax/php header:Location
提问by justanotherhobbyist
I have a Bootstrap modal with an Ajax login form.
Displaying errors and everything works just fine until the result from login.phpis header('Location: index.php');
我有一个带有 Ajax 登录表单的 Bootstrap 模式。显示错误并且一切正常，直到login.php的结果为 header('Location: index.php');
I handle the result like this:
我处理这样的结果：
var hr = new XMLHttpRequest();
// Set content type header information for sending url encoded variables in the request
hr.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
// Access the onreadystatechange event for the XMLHttpRequest object
hr.onreadystatechange = function() {
if(hr.readyState == 4 && hr.status == 200) {
var return_data = hr.responseText;
document.getElementById("status").innerHTML = return_data;
}
}
The problem is that when the login is successful and I get the header('Location: index.php');response index.phpis opened in div.status.
问题是，当登录成功并且我得到header('Location: index.php');响应index.phpis open in div.status.
Is there an easy way to translate the PHP header to a redirect in javascript?
有没有一种简单的方法可以将 PHP 标头转换为 javascript 中的重定向？

You can detect if the request is an ajax request. If it is return a json object that has the desired location otherwise do a typical php redirect.
您可以检测请求是否是ajax 请求。如果它返回一个具有所需位置的 json 对象，则执行典型的 php 重定向。
<?php
function isAjax() {
return !empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest';
}
if(isAjax()) {
echo json_encode(array("location" => "index.php"));
} else {
header("Location: index.php");
}
?>
Once you get the json object back in javascript redirect the user using
一旦你在 javascript 中获得 json 对象，就使用重定向用户
document.location = json.location;

You should use javascript to rewrite the document.locationinstead of sending a HTTP header. It will give the user the same basic experience as a traditional redirect response from a full page request.
您应该使用 javascript 来重写document.location而不是发送 HTTP 标头。它将为用户提供与来自整页请求的传统重定向响应相同的基本体验。
