捕捉浏览器中的JS运行时错误,主要通过监听window.onerror来实现。但是对于不同的脚本执行方式以及不同的浏览器,能捕获到的信息会有区别。
window.onerror 讲接收3个参数:
msg
:错误描述,比如:a is not definedurl
:出错脚本所在的urllineNumber
:出错脚本的行数
本文将对不同浏览器和不同的脚本执行方式进行测试,并总结这些区别。

有一存有整数的数组 A[n] (n <= 2^31 - 1, 但需要的话可以再扩大), 其中 0 <= i, A[i] <= n-1 且 i!=j 时 A[i]!=A[j] (即一个排列). 用你认为*最高效*的方法求 B=A^(-1) (即对范围内满足 A[B[i]]=i 的 B) |

This writeup describes a tricky Scala serialization issue that we ran into while porting Spark to Scala 2.11.
First, let's create a factory that builds anonymous functions:
class FunctionFactory extends Serializable {
// This method returns a function whose $outer scope is this class.
// Note that the function does not reference any variables in this scope,
