How can I get the first value of json object? The object contains dynamic values and I need always first value of the object
errors = {
state: [ 'The state field is required.' ],
city: [ 'The city field is required.' ]
}
You can use Object.values.
let firstValue = Object.values(errors)[0]

I'm trying to add a new item (a placeholder) to an array -- to each node
My array looks as follow:
And I wanna add the following key/value under value Year: "2010"
I have tried *json1.push("Year", "2010")* but that just creates a new entry
If you want to add it to the first object on the array, use
json1[0]["year"] = "2010"

I want to push an item into an array that in that have objects in them, like this:
var testarray = [
{
first: "See this?",
second: "Oh my!"
},
{
first: "Nice!",
second: "Amazing!"
}
]
You can see that I for this variable/array, I can't just use this testarray.push("Wonderful!"). Please show me how I can push things into these sort of arrays.
The "multiple things" are objects. Push another object in the same format.
testarray.push({first: "Wow!", second: "Wonderful!"});

I'M TRYING TO HANDLE THIS DATA IN JAVASCRIPT SO HOW CAN I REMOVE DATA ACCORDING TO THE ID NUMBER THE FIRST NUMBER
600030/01/2018/163904
600010/01/2014/3789
600030/01/2020/47104
600030/01/2012/39104
600010/01/2011/93817
how can i remove all 600030 data so i get
600010/01/2014/3789
600010/01/2011/93817
If all data shaped in Array and element is instance of String.
I would recommend Array.prototype.filter and String.prototype.startsWith();
let data = [
'600030/01/2018/163904',
'600010/01/2014/3789',
'600030/01/2020/47104',
'600030/01/2012/39104',
'600010/01/2011/93817',
];
let filteredData = data.filter((d)=>!d.startsWith('600030'));
console.log( filteredData );
Result is
[
'600010/01/2014/3789',
'600010/01/2011/93817'
]

I am trying to declare an integer Array but don't know how to do this. Is it possible to declare a int array in Vue.
In your script , just add this below :
data(){
return {
your_array : [1,2,3,4,5,6]
}
}
your_array is just an example, the variable name can be any anything.

I am integrating jqbarGraph, the demo worked fine. I want to make the values dynamic.
this is my json response
{"success":false,"message":{"12":7887,"11":159}}
I need an array like this
graphByMonth = new Array(
[7887,12],
[159,11]
);
Need to create dynamic array from JSON data.
Does this work?
var graphByMonth = [],
jsonResponse = {"success":false,"message":{"12":7887,"11":159}},
data = jsonResponse.message;
Object.keys(data).forEach(function (k, i ) {
graphByMonth.push([data[k],+k]);
});
console.log(graphByMonth);
