jQuery的Ajax错误{"readyState":0,"responseText":"","status":0,"statusText":"error"} [英] jquery ajax error {"readyState":0,"responseText":"","status":0,"statusText":"error"}
问题描述
我试图做一个Ajax请求
$。阿贾克斯（{
类型：后，
网址：的download.php
错误：功能（数据，状态，ERR）{
警报（JSON.stringify（数据））;
}，
数据：FILEID =+ FILEID
}）;
此请求警报{readyState的0的responseText：，状态：0，状态文本：错误}
我有搜索在谷歌所有的我都拿出了一个跨站点AJAX调用（这这显然不是）
我试图把完整的URL中，它做同样的事情。
我唯一能想到的是头，我不知道什么是错的。下面是从萤火请求头
主机www.mydomain.com
用户代理的Mozilla / 5.0（Windows NT的6.1; RV：5.0）的Gecko / 20100101火狐/ 5.0

我添加了一个不同的页面上的其他要求，它工作得很好，但这个一直没有头的其他要求是：
主机www.mydomain.com

我遇到了同样的问题：如何注册用户每次点击该链接
现在的问题是逸岸，如果你不停止弹出，Ajax请求无法完成，你会得到的readyState：0
我已经做了另一个版本的上面，也许是更具可读性（即使更详细）
/ * ------------------------------------ --------------------------------------
*该插件'下载'类在每一个页面的锚标记（链接）前
*此脚本没有休息
*
*记得要改变'your_php_file你们用一
* ------------------------------------------------- ------------------------- * /
$（文件）。就绪（函数（）
{
//检查是否有带班下载的任何链接
如果（typeof运算$（'下载'）！=未定义）
{
VAR链接= $（'下载'）;
//运行此为每个下载链接
对于（VAR I = 0; I＆LT; links.length;我++）
{
//设置点击行为
链接[I] .onclick =功能（五）
{
//获取下载名称
VAR ATTR = this.attributes，
HREF = attr.href.textContent，
ELEM = href.split（'/'），
ELEM = ELEM [elem.length - 1];
//发送的下载文件名，只有在完成请求之后，让用户下载的文件
$阿贾克斯（
{
键入：POST，
数据类型：文本，
//'your_php_file'必须是ABSOLUT或相对路径！
网址：your_php_file，
//ELEM是包含下载名称的变量
//你可以通过$ _ POST ['download_name']调用它在你的PHP文件
数据：{download_name：ELEM}，
//这里，我们去魔法：
请求完成//运行后弹出的下载
完成：函数（）
{
window.location.href = HREF;
}
}）;
//停止默认的行为，直到Ajax请求进行完
即preventDefault（）;
};
}
}
}）;
I am trying to do an ajax request
$.ajax({
type: "post",
url: "download.php",
error: function(data, status, err){
alert(JSON.stringify(data));
},
data: "fileid="+fileid
});
this request alerts "{"readyState":0,"responseText":"","status":0,"statusText":"error"}"
I have searched on google all i have come up with is a cross site ajax call(which this is obviously not)
I have tried putting the full url in and it does the same thing.
the only thing i can think of is the header and i don't know what would be wrong with it. Here is the request header from firebug
Host www.mydomain.com
User-Agent Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0
Accept */*
Accept-Language en-us,en;q=0.5
Accept-Encoding gzip, deflate
Accept-Charset ISO-8859-1,utf-8;q=0.7,*;q=0.7

X-Requested-With XMLHttpRequest
Referer http://www.mydomain.com/
Content-Length 8
Cookie PHPSESSID=27b7d3890b82345a4fc9604808acd928
I have added another request on a different page and it works just fine but this one keeps failing the header for the other request is:
Host www.mydomain.com
User-Agent Mozilla/5.0 (Windows NT 6.1; rv:5.0) Gecko/20100101 Firefox/5.0
Accept text/plain, */*; q=0.01

I came across the same issue: how to register every time a user click the link.
The problem is infact that if you don't stop the pop up, the ajax request doesn't complete and you get readyState: 0!
I've done another version of the above that maybe is more readable (even if more verbose)
/* --------------------------------------------------------------------------
* Before that add 'downloads' class to every anchor tag (link) in your page
* This script does the rest
*
* remember to change 'your_php_file' with the one you use
* -------------------------------------------------------------------------- */
$(document).ready( function()
{
// Check if there is any link with class 'downloads'
if ( typeof $('.downloads') != 'undefined' )
{
var links = $('.downloads');
// Run this for every download link
for ( var i = 0; i < links.length; i++ )
{
// Set click behaviour
links[i].onclick = function(e)
{
// Get download name
var attr = this.attributes,
href = attr.href.textContent,
elem = href.split('/'),
elem = elem[elem.length - 1];
// Send the download file name and only after completing the request let the user download the file
$.ajax(
{
type : "POST",
dataType : "text",
// 'your_php_file' must be an ABSOLUT or RELATIVE path!
url: your_php_file,
// 'elem' is a variable containing the download name
// you can call it in your php file through $_POST['download_name']
data: { download_name: elem },
// here we go magic:
// after the request is done run the popup for the download
complete: function()
{
window.location.href = href;
}
});
// Stop default behaviour until ajax request has been done
e.preventDefault();
};
}
}
});
