My API provides JSON data structured like this:
[{"NAME":"john","SURNAME":"johny","ADULT":"3","CHILD":"3","BABY":"0",}]
In my JavaScript function, I need to send a request to a web service that will update the value of "BABY" from "0" to "1". Can this be achieved without relying on jQuery?
Here we have a typical JavaScript array with a common JavaScript object nested within. If I understand correctly, to modify the "BABY" property in the provided code snippet, you simply need to access it and update its value:
// responseData is equal to [{"NAME":"john", ... ,"BABY":"0"}]
responseData[0].BABY = '1';
To retrieve the object in the array, make sure to use arr[0]. Since the data type of BABY is a string value of 1, you should set it using arr[0].BABY = "1" rather than arr[0].BABY = 1.
var arr = [{"NAME":"john","SURNAME":"johny","ADULT":"3","CHILD":"3","BABY":"0",}];
arr[0].BABY = "1";
console.log(arr);I'm working with a JavaScript code that creates a new element when a button is clicked. I have a question about it. Here's the JavaScript code snippet: var comment = document.querySelector("#AddComment"); var req = new XMLHttpRequest(); if(comm ...
