I can not convert this string to object.Why I am getting this error? please help.
onSignup(data:any){
localStorage.setItem('users',JSON.stringify(data));
let users = JSON.parse(localStorage.getItem('users'));
}
Try using function onSignup(data: any) { localStorage.setItem('users', JSON.stringify(data)); let users = JSON.parse(localStorage.getItem('users') as string); }
If you are using typescript you can't pass a string | undefined when a string is expected.

So I have following numbers and I would like to format it in the following way
450.03,999,999 -> 450.03
2,597.6,099,999 -> 2,597.60
69.2 -> 69.20
100,780.090,100 -> 100,780.09
Could you assist with this issue? Thank you in advance.
you can get it done this way. I hope it would work for you.
let value = "2,597.6,099,999";
let num = Number(value.replace(/,/g, ""));
let result = num.toLocaleString(undefined, {minimumFractionDigits: 2})

var Structure[undefined]
function run{
Structure[0]
}
function setStructure(structure){
Structure[0]=structure
}
setStructure(House);
function House(){
//nothing
}
Why is the return of House() function not in Structure[0]?
It is for a Minecraft PE mod.
I suppose you intended this:
function run{
Structure[0]() // <--- notice the parentheses.
}
Without the parentheses, the function run does not do anything. It just references the function, without invoking it.

I want to add data {"address" : "http://ebay.com"} to the second child of this json data i.e in the bracket with the data "api" : "Ebay".
How can I do that with jQuery?
{"Amazon":[
{"price":"19,799.00","delivery":"FREE","api":"Amazon"},
{"price":"29,999","delivery":"FREE","api":"Ebay"}
]
}
Try,
var obj = {"Amazon":[ {"price":"19,799.00","delivery":"FREE","api":"Amazon"},{"price":"29,999","delivery":"FREE","api":"Ebay"} ] };
obj.Amazon[1].address = "http://ebay.com";
or use $.merge(obj1,obj2) function
var obj = {"Amazon":[ {"price":"19,799.00","delivery":"FREE","api":"Amazon"},{"price":"29,999","delivery":"FREE","api":"Ebay"} ] };
$.merge(obj.Amazon[1], {
address: "http://ebay.com"
});
