jquery ajax call - get returning value if dataType is simply a text (string)
提问by yorgos
I have the following code.
我有以下代码。
$.ajax({
type: "POST",
url:"blahblah.php",
data: "{}",
async: true,
dataType: "text",
success: function() {
if(returning data from blahblah.php == true)
window.location.href="http://www.blahblah.com/logout.php";
}
});
1) No data need to be sent.
1) 不需要发送数据。
2) File "blahblah.php" does some processing and returns either true or false.
2) 文件“blahblah.php”进行一些处理并返回真或假。
3) I want to get the response and If true redirect to another php page.
3）我想得到响应，如果是真的重定向到另一个 php 页面。
I do not know how to read the returning data of the function in the blahblah.php file!!
blahblah.php文件中函数的返回数据不知道怎么读取！！
Thank you in advance. George
先感谢您。乔治

You have to pass a variable into the successcall.
您必须将变量传递给success调用。
$.ajax({
type: "POST",
url:"blahblah.php",
data: "{}",
async: true,
dataType: "text",
success: function( data ) {
console.log(data);
}
});
If the success method runs then you have successfully submitted the file and can redirect with a simple document.location = "http://www.example.com/somewhere.php
如果成功方法运行，则您已成功提交文件，并且可以使用简单的重定向 document.location = "http://www.example.com/somewhere.php

Have you tried setting dataType to 'json'?
Also, you're not actually retrieving the response from the server on a successful callback. Try this:
您是否尝试将 dataType 设置为'json'？此外，您实际上并不是在成功回调时从服务器检索响应。尝试这个：
$.ajax({
type: "POST",
url:"blahblah.php",
data: "{}",
async: true,
dataType: "json",
success: function(response) {
if(response == true) {
window.location.href="http://www.blahblah.com/logout.php";
}
}
});

If your success event is not call then you may be get return data using complete event
如果您的成功事件没有被调用，那么您可能会使用 complete 事件获取返回数据
example
例子
complete: function (data) {
alert(data.responseText);
},
using this you can get response data in this event
使用这个你可以在这个事件中获得响应数据
