如何在jQuery事件触发的Angular组件内调用函数? [英] How to call a function inside an Angular component triggered by jQuery events?
本文介绍了如何在jQuery事件触发的Angular组件内调用函数?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个使用jQuery(FineUploader)的第三方组件.上传文档后，它会在javascript/jquery中触发一个事件，此时，我需要从Angular组件外部的jquery代码中调用Angular组件内部的函数.
I have a third-party component that using jQuery (FineUploader). When a document gets uploaded, it fires an event in javascript/jquery and I need to, at that point, call a function that is inside my Angular component from the jquery code that is outside my Angular component.
角度按钮可以正常工作，但是我无法通过jQuery按钮成功调用该函数.
The angular button works as expected but I can't get the jQuery button to call the function successfully.
