在JavaScript中，如何从字符串中提取经度和纬度 [英] In JavaScript, How to extract latitude and longitude from string

问题描述

我正在从数据库中提取一个字符串，该字符串需要分别解析为纬度和经度， 该字符串被定义为点"，格式如下:

I am extracting a string from a database which needs to be parsed into latitude and longitude separately, The string is defined as a "point", in the following format:

(2.340000000,-4.50000000)

我试图删除括号，然后使用方法split()对其进行解析，但是我无法提出能正确完成工作的正则表达式:

I am trying to remove the parenthesis, and then parsed them with the method split() but I haven't been able to come up with a regular expressions that does the job right:

到目前为止，我已经尝试了许多替代方法，并且

So far I have tried many alternatives, and

var latlong = "(2.34000000, -4.500000000)"
latlong.replace('/[\(\)]//g','');
var coords = latlong.split(',');
var lat = coords[0];
var long = coords[1];

如果我运行它，我得到的是: NaN, -4.500000

If I run that, all I got is: NaN, -4.500000

我做错了什么? 谢谢！

What am I doing wrong? Thanks!

推荐答案

似乎可以正常工作，但是你多了一个斜杠

Seems to work, but you had an extra slash

var value = '(2.340000000,-4.50000000)';

//you had an extra slash here
//           ''''''''''''''''v
value = value.replace(/[\(\)]/g,'').split(',');

console.log(value[0]);
console.log(value[1]);​
