我有一个增强的网格并激活了“打印机”插件。此外，我已经制作了一个dijit /按钮并将其连接到一个调用print方法的onClick事件。事件被解雇所以没有问题。问题是，它不起作用。我在Opera控制台中收到以下消息：
Uncaught exception: TypeError: Cannot convert 'str' to object

以下是该活动的代码：
require([
"dijit/registry"
],function(registry) {
var grid = registry.byId('grid');
grid.printSelected({
"title": "test"
});
});
有人知道我能做什么，让这个插件上班？
PS：我也尝试使用谷歌浏览器进行打印，但这两种方法都没有用......
