【问题描述】:
在这里发帖:http://community.phonegap.com/nitobi/topics/jquery-ajax-calls-all-of-the-sudden-do-not-work
这是过去一两周的全新错误。基本上,我在 PhoneGap 中的 index.html 文件的头部有一个 ajax 调用,它的状态码为 0不工作。我还确认所有 AJAX 调用都不起作用。
我尝试了很多解决方案,但没有任何效果。
我试过了:
meta http-equiv="Content-Security-Policy" content="default-src *; style-src * 'self' 'unsafe-inline' 'unsafe-eval'; script-src * 'self ' 'unsafe-inline' 'unsafe-eval';">
添加了 $.support.cors = true;
在服务器上的 htaccess 文件中添加了 Header set Access-Control-Allow-Origin "*"
尝试了不同版本的白名单插件。
尝试了不同形式的访问源设置。
尝试将内联 JS 从 index.html 移动到单独的 JS 文件中。
已验证该代码行在 localhost 和通过 Chrome 从不同的 Web 服务器中均有效。
请帮忙。
这是我的 config.xml:

这是通过 AJAX 抓取页面的脚本:
<script>
var dev_mode = true;
if (dev_mode) {
alert('Development Mode Active - You will see popups used for debugging purposes.');
var scripts_url = 'http://dev.xxxxxxx/app/scripts';
} else {
var scripts_url = 'http://xxxxxxxxx/app/scripts';
}
jQuery.ajax({
type : "POST",
url : scripts_url,
success: function(html) {
jQuery('head').append(html);
},
error: function(xhr, status, err) {
if (dev_mode) {
alert('error getting scripts: ' + status);
alert('error getting scripts: ' + err);
alert('error getting scripts: ' + xhr.responseText);
alert('error getting scripts: ' + xhr.status);
alert('error getting scripts: ' + xhr.statusText);
alert('error getting scripts: ' + JSON.stringify(xhr));
}
}
});
</script>
AJAX 调用错误,状态为 0。
答案:
这是你的第一个应用吗?
不是我的第一个 PhoneGap 应用,而是我的第一个非常复杂的应用。
您的目标平台及其目标版本是什么?
针对除 Blackberry 之外的所有平台(在出现此 AJAX 错误之前已在 iOS、Android 和 WP 上进行测试)
您使用的是 CLI、SDK 还是 Build ?
构建
【问题讨论】:
-
请在您的帖子中回答以下问题。这是您的第一个应用程序吗?您的目标平台及其目标版本是什么?你在使用CLI, SDK or Build 吗?一旦您回答了帖子中的问题*,请在 cmets 中回复,以便我知道您已在帖子中添加信息。
-
已答复。还添加了指向我发布此问题的其他地方的链接。
-
您在哪个平台上遇到过问题?如果仅在 iOS 上,您是刚刚切换到 iOS 9 SDK 还是 iOS 9 设备?您是否添加了适当的应用程序传输安全设置?日志中显示了什么?
-
@BigBrother6 是的。我有同样的问题。重复什么是目标平台和它们的目标版本。请回答。是的,这很重要——这就是我要问的原因。另外,您使用的是模拟器、网络浏览器还是设备。
-
它适用于网络浏览器,但不适用于安卓设备。这是我在 Android 5.0.1 上遇到的一个全新问题。我想我主要针对的是最新版本的 iOS 和 Android。它已经工作了几个月,没有专门针对任何版本,我认为我没有做出任何会破坏它的更改。我非常感谢您的帮助,我只是不明白为什么特定的版本定位会产生很大的不同。再次感谢。
