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 defined
  • url:出错脚本所在的url
  • lineNumber: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。

网上找的经纬度差距离计算
public class t {
public static void main ( String[] args ) {
double earthRadius = 6371; //地球半径,单位km
double lat1 = 31.215961;
double lng1 = 121.456083;
// 经纬度差0.000001
double lat2 = 31.215960;
double lng2 = 121.456082;
double dLat = Math.toRadians ( lat2 - lat1 );
# -*- coding=utf-8 -*-
import collections
# Usage:
# 我的做法是把WordsDetector.py里的结果输出到文件,
# 然后把文件名放到下面的names列表中,运行本程序。
names = ['name0',
'name1',
'name2',
