I got a key-value object like this:
items = {1:"a",2:"v",3:"u"};
But i want it like this.
items = [{"key":"1","value","a"},{"key":"2","value","v"},{"key":"3","value","u"}];
What is the best way to do this?
I have already tried to do this with $.each.
var items = {1:"a",2:"v",3:"u"};
var newItems = [];
$(items).each(function(k,v){
newItems.push({"key":k,"value":v});
});
And please tell me what is wrong with this question!
Try this-
var items = {1:"a",2:"v",3:"u"};
var obj=[];
for(var i in items){
obj.push({"key":i,"value":items[i]});
}
console.log(obj)

suppose the object is obj ={foo:"bla,bla2,bla3",bar:"bla,bla5"}
I want to convert it to 'obj={foo:["bla","bla2","bla3"],bar:["bla","bla5"]}'
Don't know why you want to do that, but here you can just loop through obj with a for...in loop and split the strings by commas:
const obj = {foo:"bla,bla2,bla3",bar:"bla,bla5"};
for (name in obj) {
obj[name] = obj[name].split(',');
}
console.log(obj)

So I’m trying to check names through an array and I don’t want to have to use
if (<array name>[0,1,2,3,4,5,6,7])
{ code in here }
depend on what you are trying to do u can use forEach or map
let arr = [1,2,3,4,5,6,7,8,9,10];
arr.forEach((item)=>{
console.log(`${item} is greater than 5 : ${item>5}`)
})

I would like to know whether it is easier to store all the data from a text input where the user has to enter their surname in an array or in an object. And how do I do so?.
Thanks in advance
You could do something like this:
var dataArray = [];
function storeData() {
var data = document.getElementById("yourInput").value;
dataArray.push(data);
}
This method uses arrays - personally I find them more easier to use than objects.

Below is my JSON object
{"Decision":[{"recid":"1183","reason":"Approved as Requested","decision":"Approved","approvalamt":"","comment":""},{"recid":"662","reason":"3","decision":"Rejected","approvalamt":"","comment":""},{"recid":"752","reason":"Approved People Resources; But No Funding Approved","decision":"Approved","approvalamt":"","comment":""}]}
How do I get length of this.In this example it should return me 3.
My Object name is DecisionObj which have above listed elements.
var string = '{"Decision":[{"recid":"1183","reason":"Approved as Requested","decision":"Approved","approvalamt":"","comment":""},{"recid":"662","reason":"3","decision":"Rejected","approvalamt":"","comment":""},{"recid":"752","reason":"Approved People Resources; But No Funding Approved","decision":"Approved","approvalamt":"","comment":""}]}';
var object = JSON.parse(string);
alert(object.Decision.length);
Arrays have length property. You can use that.
var length = DecisionObj.length;

I am having a hard time learning how to iterate through nested arrays, and storing specific array values in javascript.
$('#btn2').click(function(e){
e.preventDefault();
var res = hjs.getValue([1,2,3],['bri', 'alert','name', 'hue', 'sat']);
console.log(res);
});
When #btn2 is clicked on, the following is outputed to my console:
If I'd like to access anyone of these values how would I do so? How do I store the value in a variable?
you can iterate through the object and get the value you want:
$('#btn2').click(function(e){
e.preventDefault();
var res = hjs.getValue([1,2,3],['bri', 'alert','name', 'hue', 'sat']);
for(var i in res)
{
if (res.hasOwnProperty(i)) {
var obj = res[i];
console.log('name: ', obj.name);
console.log('sat: ', obj.sat);
}
}
});
