Javascript将字符串拆分为数组字典（键->值）（正则表达式） [英] Javascript split a string into an array dictionary (key -> value) (regex)

问题描述

目标是将字符串解析为javascript中的数组字典。

The aim is to parse a string into an array dictionary in javascript.

例如，这可能是需要解析的字符串

For example this maybe the string that needs to be parsed

k = 23：3/24：32b = 43：532：45/3：3253

"k=23:3/24:32b=43:532:45/3:3253"

我希望该字符串变成一个这样的字典（键-值）

k-23：3 / 24:32

k - 23:3/24:32

b-43：532：45/3：3253

b - 43:532:45/3:3253

我的最初想法是搜索[aZ] \ *。*并使用正则表达式将其拆分为匹配项。

My initial idea was to search for [a-Z]\*.* and split it into matches using regex.

但是，我不认为这会起作用，因为这也会带来 b ，这不是我想要的。另外，我无法使它正常工作（我是regex的新手）。

However, I do not think this would work as this would also bring over b which is not what I want. Also, I was not able to get this to work (I'm new to regex).

仅等于永远在键和变量之间（永远不在值中）。密钥也只能是单个字符而不是单词。

An equals will only ever be between a key and variable (never in the value). The key will also only ever be a single character not a word.

var test = "k=23:3/24:32b=43:532:45/3:3253";
var r = /(.*)([a-Z])(//*)(*.)/

上面是我打算做的事情，但我似乎什么也没用。

Above was my idea of going about it but I can not seem to get anything to work.

推荐答案

可能使用 /.= [^ =] +（？！=）/ g 来匹配键值对，而无需进一步了解键和值可能包含哪些字符：

Possibly use /.=[^=]+(?!=)/g to match the key value pair without further knowledge of what characters are possible for the key and value:

• 此处。= 与等号前的键（单个字符）匹配;


• [^ =] +（？！=）匹配所有非 = 之后的字符，直到下一个等号之前的一个字符（使用负向前看限制贪婪匹配）或字符串的结尾；

• Here .= matches the key (single character) right before the equal sign;
• [^=]+(?!=) matches all non = characters after until one character before the next equal sign (restrict the greedy match using a negative look ahead) or the end of string;

var test = "k=23:3/24:32b=43:532:45/3:3253";

var result = {}

test.match(/.=[^=]+(?!=)/g).forEach(
  m => {
    var [k, v] = m.split('=')
    result[k] = v
  }
)

console.log(result)
