Error.prototype.lineNumber

非标准
该特性是非标准的，请尽量不要在生产环境中使用它！

lineNumber 属性的值为抛出错误的代码在其源文件中所在的行号。

示例

使用 lineNumber

var e = new Error('Could not parse input');
throw e;
console.log(e.lineNumber) // 2

监听 error 事件的示例

window.addEventListener('error', function(e) {
  console.log(e.lineNumber); // 5
});
var e = new Error('Could not parse input');
throw e;

这不是一个标准化的属性，缺乏广泛的支持。参见下面的浏览器兼容性表格。
