使用javascript检查特定控制台错误是否发生/存在 [英] Checking if specific console error occurred/exists with javascript

问题描述

我想使用javascript检查某个控制台错误，如果发生，请亲自检查alert().

I would like to check if a certain console error has occurred using javascript, and alert() myself if it has.

错误看起来像这样:

00:00:34:0359 TimeEvent.COMPLETE
    (anonymous function) @ VM17617:1

该算法将如下所示:

function checkError(console) {
    if(console.error === "TimeEvent.COMPLETE") {
        alert("The error is present");
    }
}

我对控制台不是很熟悉，并且对Google的研究还不够深入.有人可以指出我正确的方向吗?

I'm not very familiar with the console, and haven't gotten much further with Google research. Can somebody point me in the right direction?

推荐答案

我最终通过遵循

I ultimately solved my question by following this blog post on taking over the console with javascript.

这是我的最终代码:

var original = window.console
window.console = {
    error: function(){      

        //Gets text from error message.
        errorText = arguments['0'];

        if (errorText.includes('TimeEvent.COMPLETE')) {
            //DO STUFF HERE
        }

        original.error.apply(original, arguments)
    }
}
