How to retrieve data from json file

I am having trouble with accessing my json file from my javascript file. I would like to change the object to a different text in my json file once a submit button is clicked on the webpage. I am aware that I would use ajax to achieve this goal, but I do not know how to access the json file.
This is the db.json file
{
{
"assets": [
{
"id": "0946",
"manufacturer": "SONY",
},
{
"id": "0949",
"manufacturer": "AUDIOTECNIA"
}
],
"transfers": [
{
"id": 1,
"status": "in-progress"
}
]
}
This is my Javascript file
$('form').on('submit', function(e){
e.preventDefault();
parsedData = JSON.parse(db.json);
console.log(parsedData[0].id)
//Changing Status
$.ajax({
type: "PATCH",
url: `http://localhost:3000/transfers/`
});
I've tried using parseData because I read that is how to retrieve the object, from the json file, but I do not believe I am writing it correctly. What documentation or steps would one recommend for solving this issue?

You have an extra comma after "in-progress",
const parsedData = JSON.parse(`{
"transfers": [ {
"id": 1,
"status": "in-progress"
}]
}`)
Then, to access id in parsedData:
console.log(parsedData.transfers[0].id)

You did not initialize the variable parsedData.
var parsedData = JSON.parse(db.json);

JSON array not working for $http service

I am new to angular and trying to develop an application having nested
ng-repeat and after submitting the form it should hit the rest api.
I have been using $http to make rest api calls. The code gets submitted
with normal data but does not get submitted with nested ng-repeat when i
click the save button. Below I have provided the code with details.
The whole data should be shown in the console. I might have made some
mistake somewhere.Thanks in advance.
JS
$scope.saveVenFormData = function(vendet){
console.log($scope.vendet);
$scope.venFullAddress.push({
'vendorName': $scope.name,
'panNum': $scope.panNum,
'personName': $scope.venBusDetails.personName,
'mobileNum': $scope.venBusDetails.mobileNum,
'workNum': $scope.workNum,
'emailid': $scope.emailid,
'addressLine1': $scope.addressLine1,
'addressLine2': $scope.addressLine2,
'city': $scope.city,
'state': $scope.state
});
var dataObj = $scope.venFullAddress;
// console.log($scope.dataObj);
$http.get('/showVendors').success(function(data){
console.log(angular.toJson(data));
});
var res = $http.post('http://localhost:8080/dman/mm', dataObj);
res.success(function(data, status, headers, config) {
$scope.message = data;
});
res.error(function(data, status, headers, config) {
alert( "failure message: " + JSON.stringify({data: data}));
});
};
JSON structure:
{
"vendor": {
"vendorName": "",
"panNum": "",
"venBusDetails": [{
"personName": "",
"mobileNum": "",
"workNum": "",
"emailid": "",
"venContDetails": [{
"addressLine1": "",
"addressLine2": "",
"city": "",
"state": ""
}]
}]
}
}

For convenience I have added a json structure. I need to access all the
data from the form and hit the rest api.
The above is the link to the plunker. Thank you.

Try this
$scope.dataObjToPost = {
"vendor": {
"vendorName": $scope.vendet.vendorName,
"panNum": $scope.vendet.panNum,
"venBusDetails": [{
"personName": $scope.venBusDetails[0].personName,
"mobileNum": $scope.venBusDetails[0].mobileNum,
"workNum": $scope.venBusDetails[0].workNum,
"emailid": $scope.venBusDetails[0].emailid,
"venContDetails": [{
"addressLine1": $scope.venContDetails[0].addressLine1,
"addressLine2": $scope.venContDetails[0].addressLine2,
"city": $scope.venContDetails[0].city,
"state": $scope.venContDetails[0].state
}]
}]
}
} //And send this data to POST method
You used $scope.name in JS file but in HTML view you used ng-model="vendet.vendorName". Thats why it is always undefined.

Return JSON results as JS array with AJAX?

Apologies in advance - I am new to this and so other answers have not been able to help me.
I have used AJAX to send data to a PHP script (part of a 3rd party API). The PHP script returns the results as JSON, but I have no idea how to format these on my HTML page.
Ultimately, I would like to save the JSON results as an array and then use JS/Jquery to format them on the page.
I am not sure how to modify the PHP and AJAX scripts to achieve this. Can anyone point me in the right direction?
My AJAX:
$.ajax({
type: 'POST',
url: 'calculator.php',
data: {toPostcode: toPostcodeValue, parcelLengthInCMs: parcelLengthInCMsValue, parcelHeighthInCMs: parcelHeighthInCMsValue, parcelWidthInCMs: parcelWidthInCMsValue, parcelWeightInKGs: parcelWeightInKGsValue},
success: function(data) {
<!--NOT SURE WHAT TO PUT HERE-->
}
})
PHP (after the calculator does its thing - not sure if it needs to be changed):
$serviceTypesJSON = json_decode($rawBody);
echo json_encode($serviceTypesJSON);
The expected JSON results should look like:
{
"services": {
"service" : [
{
"code": "AUS_PARCEL_REGULAR",
"name": "Parcel Post (your own packaging)",
"speed": 2,
"price": 6.95,
"max_extra_cover": 5000,
"extra_cover_rule": "100,1.5,1.5",
"icon_url": "http://test-static.npe.auspost.com.au/api/images/pac/regular_post_box.png",
"description": "Based on the size and weight you've entered",
"details": "Check our ",
"delivery_time": "Delivered in up to 3 business days",
"ui_display_order": 1,
"options": {
"option": [
{
"code": "AUS_SERVICE_OPTION_STANDARD",
"name": "Standard Service",
"price": "0.00",
"price_type": "static",
"option_type": "optional",
"ui_display_order": 1
},
{
"code": "AUS_SERVICE_OPTION_SIGNATURE_ON_DELIVERY",
"name": "Signature on Delivery",
"price": 2.95,
"price_type": "static",
"option_type": "optional",
"tooltip": "Signature on Delivery provides you with the peace of mind that your item has been delivered and signed for.",
"ui_display_order": 2,
"suboptions": {
"option": {
"code": "AUS_SERVICE_OPTION_EXTRA_COVER",
"name": "Extra Cover",
"option_type": "optional",
"price_type": "dynamic",
"tooltip": "Extra Cover provides cover for loss, damage or theft of your item and will fully compensate you to the value specified for your item.",
"ui_display_order": 1
}
}
}
]
}
},

You can do two things, if the return data is JSON use dataType: "json" in the AJAX call.
Edit 1
If you are using dataType: "json". Which is more preferred if you are sure the data return is JSON string. data variable in the success will directly give you the JSON object. I think you can access it like data['services'].
success: function (data) {
jsonObj = $.parseJSON(data);
//this gives you the inner onject of the return data
servicesObj = jsonObj.services;
}
Or you can just get the data then use jQuery.parseJSON() to parse the data string into JSON object.
$.ajax({
type: 'POST',
url: 'calculator.php',
data: {
toPostcode: toPostcodeValue,
parcelLengthInCMs: parcelLengthInCMsValue,
parcelHeighthInCMs: parcelHeighthInCMsValue,
parcelWidthInCMs: parcelWidthInCMsValue,
parcelWeightInKGs: parcelWeightInKGsValue
},
success: function (data) {
jsonObj = $.parseJSON(data);
//this gives you the inner onject of the return data
servicesObj = jsonObj.services; //or jsonObj["services"]
}
})

Your success function will never be called if you are using
echo json_encode(); in your php script.
You should add dataType:'json' after type:'POST' and then your success function will get called and will get the result returned by server in data

How to access second level JSON object via $.getJSON

Hi guys please take a look at this having trouble reaching second level inside a object that looks like this:
{
"results": [{
"title": "TEAM",
"subtitle": "athletes",
"offset": 0,
"icon": "info",
"relevance": 1,
"link": {
"title": "HOME",
"url": "http://www.test.com",
"id": "23458"
}]
}
and this is the code I have:
var theJson = {
init: function() {
this.url = 'http://test.com/js?jsonfeed=123123';
this.fetch();
},
fetch: function() {
$.getJSON(this.url, function( data ){
var obj = $.map(data.results, function( newObj ){
return {
title: newObj .title,
icon: newObj.icon,
topic: newObj.link.id, //??
topic: newObj["link"].id //??
topic: newObj[1].id //??
};
});
});
}
};
theJson.init();
My question is how do I reach the id var in link array inside results object? Thank guys you all rock!

You are doing it correct the first and second time:
newObj.link.id
newObj["link"].id
There are both correct ways to get the id under link.

You can easily access it by index, like that:
newObj["link"][0]

display json data using xhrget (DOJO)

I am unable to figure out what is the problem with displaying json data..below is the code
var xhrGet1 = dojo.xhrGet({
url: "Page/",
handleAs: "json",
handle: function(response)
{
dojo.byId('json-data').innerHTML = response.questions[0];
}
});
Html
<div id='json-data'></div>
And my json file looks like this
{
"Info": {
"PURPOSE": ".... ",
},
"questions": [
{
"ID": 1,
"Question": "User ID",
"Information": "",
}, {
"ID": 2,
"Question": "Name",
"Information": "",
}
],
so on...any ideas??

The property handleAs : "json" in your xhr call makes the incoming json automatically eval'ed to javascript objects. So, you have to convert your javascript object back to string using JSON.stringify.
e.g. :
dojo.byId('json-data').innerHTML = JSON.stringify(response.questions[0]);
You can also use dojo.toJson for the same purpose. It uses json.stringify but has the benefit of having a second argument ("prettyprint"), allowing you to pretty-print out of the box, like this :
dojo.byId('json-data').innerHTML = dojo.toJson(response.questions[0], true);

wrap your JSON with PRE and CODE tags.
So:
dojo.byId('json-data').innerHTML = "<pre>code>" + response.questions[0] + "</code></pre>";
Also see: Display JSON as HTML for some libraries that can help you pretty-format your JSON when rendering in the browser
