希望有人可以帮助我在phonegap中开发移动应用程序时解决以下问题。我正在尝试从 WordPress 安装中读取帖子，但是当我在 chrome 上运行我的 index.html 页面时出现此错误
XMLHttpRequest 无法加载 Origin null 是 Access-Control-Allow-Origin 不允许的。
我在 WordPress 中安装了 JSON-API 插件，当我导航到我想要的页面时，我可以正常查看它。我的代码如下：
<!DOCTYPE HTML>
<html>
<header>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script>
function readSinglePost (url,target_div) {
var URL = url//+"&callback=?";
console.log(URL);
jQuery.ajax({
url: URL,
dataType: 'json',
success: function(data) {
console.log(data);
jQuery(target_div).append("<h1>"+data.post.title+"</h1>");
jQuery(target_div).append(data.post.content);jQuery(target_div).
append("<small>"+data.post.date+"</small>");
console.log(data.post.content);
}
});
}
jQuery(document).ready(function() {
var url = "http://www.example.com/api/get_post/?json=get_post&dev=1&id=5486";
var target_div = "#contents";
readSinglePost(url, target_div);
});
</script>
</header>
<body>
<div id="main">
<div id="title"></div>
</div>
</body>
</html>
