+```javascript
+{
+    imageUpload       : true,
+    imageFormats      : ["jpg", "jpeg", "gif", "png", "bmp", "webp"],
+    imageUploadURL    : "http://xxxxxxx/editor.md/examples/php/cross-domain-upload.php?test=dfdf",
+    crossDomainUpload : true,
+    uploadCallbackURL : "http://xxxxxx/upload_callback.html?test=dfdf"
+}
+```
+
+#### 跨域上传原理
+
+利用 iframe 来实现，A 站 POST 到 B 站，B 站处理上传后再跳转回到 A 站的 callback 页面，callback 页面此时在 iframe 内（即同域下），再通过 window.parent 就可以操作父页面的任意元素了。
+
+#### 跨域上传示例 PHP 版
+
+当前域名：blog.xxx.com/post.php
+
+```html
+&lt;form method="post" target="upload-iframe" enctype="multipart/form-data" action="http://static.xxx.com/uploader.php?callback=http://blog.xxx.com/upload-callback.html"&gt;
+    &lt;input type="file" name="file" accept="image/*" /&gt;
+    &lt;input type="submit" id="submit" value="开始上传" /&gt;
+&lt;/form&gt;
+&lt;iframe name="upload-iframe" style="display:none;" frameborder="0"&gt;&lt;/iframe&gt;  
+```     
+
+图片服务器：static.xxx.com/uploader.php
+
+```php
+&lt;?php
+header("Access-Control-Allow-Origin: *"); // Setting allow domian name
+
+$file = 'uploads/' . $_FILES['file']['name'];
+// 详细过程略
+move_uploaded_file($_FILES['file']['tmp_name'], $file);
+
+$location = $_GET['callback'].'?success=1&message=xxxxxxx&url=http://static.xxx.com/2015/02/15'.$file.'&temp='.date('ymdhis');
+
+header('location:' . $location);
+exit;
+?&gt;
+```
+
+当前域名：blog.xxx.com/upload-callback.html
+
+```html
+&lt;script type="text/javascript"&gt; 
+    var query = {};
+    var urlParams = window.location.search.split('?')[1];
+    urlParams = urlParams.split("&");
+
+    for (var i = 0; i&lt; urlParams.length; i++) {
+        var param = urlParams[i].split("="); 
+        query[param[0]] = param[1]; 
+    }
+
+    var imageDialog = window.parent.document.getElementById(query['dialog_id']);
+    //console.log(imageDialog, window.parent.document, window.parent, query);
+&lt;/script&gt;
+```</textarea>
