JavaScript执行错误
2019-02-20 15:34:20 更新
JavaScript执行错误在Fundebug控制台的图标如下:
由于拼写失误,测试不完善,或者是意外的边界条件,JavaScript代码在用户浏览器中执行时,有可能会出错。
下面的示例中,alert被写成了aler,因此会报ReferenceError:
aler("hello");
Fundebug插件捕获的这个错误之后,开发者将受到报警,然后可以在我们的控制台查看错误详情:
Fundebug插件捕获的错误数据如下:
{
"notifierVersion": "0.2.0",
"userAgent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.12; rv:54.0) Gecko/20100101 Firefox/54.0",
"locale": "zh",
"url": "http://localhost:4000",
"title": "Test",
"apiKey": "API-KEY",
"name": "ReferenceError",
"time": 1502863944724,
"message": "Uncaught ReferenceError: aler is not defined",
"fileName": "http://localhost:4000/test.js",
"lineNumber": 1,
"columnNumber": 1,
"stacktrace": "@http://localhost:4000/test.js:1:1\n",
"type": "uncaught",
"severity": "error"
}
JavaScript执行错误的type属性值分为caught或者uncaught两种,caught为notifyError发送的错误,而uncaught为Fundebug插件自动捕获的错误。
