const str = '{Object1=Text Goes Right Here, and Here, Object2 = Another Text Here}'

const res = str

console.log(JSON.parse(res))

我给你做了一个难看的脚本来解决一个难看的问题…；）

let string = "{Object1=Text Goes Right Here, and Here, Object2 = Another Text Here}";

let stringSplitted = string.replace(/[\{\}]/g,"").split("=")
console.log("=== Step #1")
console.log(stringSplitted)

let keys = []
let values = []
stringSplitted.forEach(function(item){
  item = item.trim()
  keys.push(item.split(" ").slice(-1).join(" "))
  values.push(item.split(" ").slice(0,-1).join(" "))
})
console.log("=== Step #2")
console.log(keys, values)

keys.pop()
values.shift()
console.log("=== Step #3")
console.log(keys, values)

let result = {}
keys.forEach(function(key, index){
  result[key] = values[index]
})
console.log("=== Result")
console.log(result)
