如何从结果正则表达式javascript获取更多详细信息

Question

Here I have a test string :

apple 01x100 02x200 03x150
banana 01x50 02 03x10

What I want as result :

{ "apple" : { "100":["01"], "200":["02"], "150":["03"] }, 
  "banana" : {"50":["01"], "10":["02","03"]}

I'm trying to use regex in javascript to parse string. The regex string

/(apple|banana)((?:\s)*(?:(?:[0-9]+)(?:\s)*)*x(?:[0-9])+)+/gi

Result:

Match 1
Full match  0-26    `apple 01x100 02x200 03x150`
Group 1.    0-5 `apple`
Group 2.    19-26   ` 03x150`

Match 2
Full match  27-48   `banana 01x50 02 03x10`
Group 1.    27-33   `banana`
Group 2.    39-48   ` 02 03x10`

As you see, in Match 1 - Group 2, only 03x150 show, 01x100 and 02x200 doesn't. In Full match it show all. Any idea to fix this and get the result I want ? Thanks

I think this will work for you:

 const input = ` apple 01x100 02x200 03x150 banana 01x50 02 03x10 lemon 02x12 15 16 17x21 ` const parse = data => { const obj = {} const findFruits = /(\\w+)\\s+(.*)/g const findMore = /\\s*([\\d\\s]+)x(\\d+)/g let temp while (temp = findFruits.exec(data)) { const tempObj = obj[temp[1]] = {} const temp2 = temp[2] while (temp = findMore.exec(temp2)) { tempObj[temp[2]] = temp[1].split(' ') } } return obj } const out = parse(input) console.log(out)
