I'm trying to use a path variable in a JSON path.
My problem is that my variable is added as a new key to the JSON object instead of replacing my path.
My Example Code
Data = {
first:{
"Name":"John",
"Age":"43"
}
}
let path = "first.name"
let value = "Jan"
Data[path] = value
console.log(Data)
Current Output
Data = {
first:{
"Name":"John",
"Age":"43"
},
"first.name": "Jan",
}
Expected Output
Data = {
first:{
"Name":"Jan",
"Age":"43"
}
}
Is there a way to solve this? Thanks for your help ๐
This script shall do what you want with an object (if I understood your problem well), until you provide it with the correct path :-)
function setAttr(obj, path, value){
let objCopy = obj;
let attrNameArr = path.split('.');
for(let idx = 0; idx < attrNameArr.length-1; idx++){
objCopy = objCopy[attrNameArr[idx]];
}
objCopy[attrNameArr[attrNameArr.length-1]] = value;
return obj;
}
Data = {
first:{
"Name":"John",
"Age":"43"
}
}
setAttr(Data, "first.Name", "Jan");
console.log(Data);it basically changes the attributes of object using the fact that objCopy and obj share the same reference.
