如何在Clojurescript中捕获任何Javascript异常？ [英] How to catch any Javascript exception in Clojurescript?

问题描述

在我的通信层中，我需要能够捕获任何JavaScript异常，将其记录下来，并按照通常的方式进行操作。
Clojurescript中捕获异常的当前语法规定我需要指定被捕获的异常的类型。

In my communication layer I have a need to be able to catch ANY javascript exception, log it down and proceed as I normally would do. Current syntax for catching exceptions in Clojurescript dictates that I need to specify the type of the exception being caught.

我试图使用nil，js / Error， js / object在catch窗体中，它没有捕获任何JavaScript异常（可以将字符串作为对象的类型）。

I tried to use nil, js/Error, js/object in the catch form and it doesn't catch ANY javascript exception (which can have string as the type of the object).

我会欣赏任何提示如何这可以在Clojurescript中本地完成。

I would appreciate any hints how this can be done natively in Clojurescript.

I found another possible answer in David Nolen "Light Table ClojureScript Tutorial"

;; Error Handling
;; ============================================================================

;; Error handling in ClojureScript is relatively straightforward and more or
;; less similar to what is offered in JavaScript.

;; You can construct an error like this.

(js/Error. "Oops")

;; You can throw an error like this.

(throw (js/Error. "Oops"))

;; You can catch an error like this.

(try
  (throw (js/Error. "Oops"))
  (catch js/Error e
    e))

;; JavaScript unfortunately allows you to throw anything. You can handle
;; this in ClojureScript with the following.

(try
  (throw (js/Error. "Oops"))
  (catch :default e
    e))
