Unable to parse JSON using dojo - javascript

I am parsing this JSON:
[{
"cities": [
{
"city": "Pune",
"state": "Maharashtra"
},
{
"city": "Mumbai",
"state": "Maharashtra"
},
{
"city": "Panaji",
"state": "Goa"
},
{
"city": "Hyderabad",
"state": "Andhra Pradesh"
},
{
"city": "Banglore",
"state": "Karnataka"
},
{
"city": "Chennai",
"state": "Tamil Nadu"
},
{
"city": "New Delhi",
"state": "New Delhi"
}]
}]
using Dojo code:
var content = "<table border = 1><tr><th>City</th><th>State</th></tr>";
dojo.forEach(jsonData.cities, function (jsonData)
{
// Build data from the JSON
content += "<tr><td>" + jsonData.city + "</td><td>" + jsonData.state + "</td></tr>";
});
content += "</table>";
However a table with no elements is displayed! What exactly do I need to change in my Dojo code?

Try this..
var DObject = [{
"cities": [
{
"city": "Pune",
"state": "Maharashtra"
},
{
"city": "Mumbai",
"state": "Maharashtra"
},
{
"city": "Panaji",
"state": "Goa"
},
{
"city": "Hyderabad",
"state": "Andhra Pradesh"
},
{
"city": "Banglore",
"state": "Karnataka"
},
{
"city": "Chennai",
"state": "Tamil Nadu"
},
{
"city": "New Delhi",
"state": "New Delhi"
}]
}]
var output = "";
for(var i in DObject[0].cities) {
var detail = DObject[0].cities[i];
output += "<tr><td>" + detail.city + "</td><td>" + detail.state + "</td></tr>";
}
alert(output);

reconstruct an array of objects from another object array

Currently, I have an array in Javascript named locations, described below:
let locations = [
{
"id": "1",
"city": "Kermit",
"state": "TX",
},
{
"id": "2",
"city": "Bloomington",
"state": "MN",
},
{
"id": "3",
"city": "Pauls Valley",
"state": "OK",
},
{
"id": "4",
"city": "Colville",
"state": "WA",
},
{
"id": "5",
"city": "Jacksboro",
"state": "TX",
},
{
"id": "6",
"city": "Shallowater",
"state": "TX"
}
]
using Javascript, I need to create another array from this array by filtering out the cities with the same states as a single array within the locations array.
required output:
locations = [
TX:[{
"id": "1",
"city": "Kermit",
"state": "TX",
},
{
"id": "5",
"city": "Jacksboro",
"state": "TX",
},
{
"id": "6",
"city": "Shallowater",
"state": "TX"
}
],
MN:[
{
"id": "2",
"city": "Bloomington",
"state": "MN",
},
],
OK:[
{
"id": "3",
"city": "Pauls Valley",
"state": "OK",
},
],
WA:[
{
"id": "4",
"city": "Colville",
"state": "WA",
},
]
]
Also, I need this array sorted in alphabetical order. If some one could give me a good approach to solve this scenario, it would be a great help.
const locations = [
{ "id": "1", "city": "Kermit", "state": "TX" },
{ "id": "2", "city": "Bloomington", "state": "MN" },
{ "id": "3", "city": "Pauls Valley", "state": "OK" },
{ "id": "4", "city": "Colville", "state": "WA" },
{ "id": "5", "city": "Jacksboro", "state": "TX" },
{ "id": "6", "city": "Shallowater", "state": "TX" }
];
const byState = {};
[...locations].sort((a,b) =>
a.state.localeCompare(b.state) || a.city.localeCompare(b.city)
).forEach(i => (byState[i.state]??=[]).push(i));
console.log(byState);
You can reduce the locations into groups by state. Once you have achieved that, you can convert the object key-value pairs to entries, sort them, and then convert them back into an object.
const locations = [
{ "id": "1", "city": "Kermit", "state": "TX" },
{ "id": "2", "city": "Bloomington", "state": "MN" },
{ "id": "3", "city": "Pauls Valley", "state": "OK" },
{ "id": "4", "city": "Colville", "state": "WA" },
{ "id": "5", "city": "Jacksboro", "state": "TX" },
{ "id": "6", "city": "Shallowater", "state": "TX" }
];
const sortObjectKeys = (obj) =>
Object.fromEntries(Object.entries(obj).sort(([a], [b]) => a.localeCompare(b)));
const groupedByState = sortObjectKeys(
locations.reduce((acc, location) => ({
...acc,
[location.state]: [...(acc[location.state] ?? []), {
...location
}]
}), {}));
console.log(groupedByState);
.as-console-wrapper { top: 0; max-height: 100% !important; }
If you want to forgo sorting, just reduce the data:
const locations = [
{ "id": "1", "city": "Kermit", "state": "TX" },
{ "id": "2", "city": "Bloomington", "state": "MN" },
{ "id": "3", "city": "Pauls Valley", "state": "OK" },
{ "id": "4", "city": "Colville", "state": "WA" },
{ "id": "5", "city": "Jacksboro", "state": "TX" },
{ "id": "6", "city": "Shallowater", "state": "TX" }
];
const groupedByState =
locations.reduce((acc, { state, ...location }) => ({
...acc,
[state]: [...(acc[state] ?? []), { ...location, state }]
}), {});
console.log(groupedByState);
.as-console-wrapper { top: 0; max-height: 100% !important; }

I've JSON array which is returned after an edit success in react-redux-saga. The record I updated before and after successfull update comes together as an element of JSON array. So, I need to replace the old resort element with the newly updated resort values and also delete the old resort.
Here, in this example, I have updated resortId(id)=15, but my redux-saga returns both-old resort and the updated new resort,clubbed together in a single element in JSON array cuz in the this.props(cuz place part in this id=15 belongs to another saga store).

How do I delete the child element resort with id=15 as this is old record before the update? And how do I rename the id of "place" to "placeId" and merge the inner parts - placeId,city,state and country to the outer part of the element - name=BBB and Id=15 and address": "NewTown","details": "jhkhkjhkjhkjh","phone": "98789797" to something like this

I have deleted the "resort" but unable to rename id in place part to placeId and merge it to the outer element.
function deleteKey(obj, keyToDelete) {
Object.keys(obj).forEach(key => {
if (key.toLowerCase() === keyToDelete) {
delete obj[key];
}
value = obj[key];
if (value instanceof Object) {
deleteKey(value, keyToDelete);
}
});
}
deleteKey(resortafterupdate, "resort");
I found a solution to flatten the child props using this answe on this link
Solution
Here's the code I modified according to my needs
function deleteKey(obj, keyToDelete) {
Object.keys(obj).forEach(key => {
if (key.toLowerCase() === keyToDelete) {
delete obj[key];
}
value = obj[key];
if (value instanceof Object) {
deleteKey(value, keyToDelete);
}
});
}
Object.flatten = function(data){
var resultMain = [];
var result = {};
function recurse(cur, prop){
if (Object(cur) !== cur){
result[prop] = cur;
}else if(Array.isArray(cur)){
for(var i=0, l=cur.length; i<l; i++)
recurse(cur[i], prop);
if(l == 0)
result[prop] = [];
}else{
var isEmpty = true;
for(var p in cur){
isEmpty = false;
recurse(cur[p], prop==="place" && p==="id"? prop+"Id" : p);
}
if(isEmpty && prop)
result[prop] = {};
}
}
for(var i=0; i<data.length; i++){
result = {};
recurse(data[i], "");
resultMain[i] = result;
}
return resultMain;
}
deleteKey(updateResorts, "resort");
console.log(Object.flatten(newlyaddedResort));

Modify JSON object using JavaScript based on title search

I have a ASP.Net hidden field which has data in JSON format as shown below
[
{
"RegionName": "USA",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "8888",
"Country": "USA",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Test",
"Email": "Test#test.com",
"Phone": "9998887777"
}
},
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
]
which is read in Javascript using below code
var value = $('#countryInvoice')[0].defaultValue;
Now I want to search this JSON using javascript based on Region name and delete the record from the hidden field. So I want to remove the data point for say USA so only the below remains
[
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
]
Can someone please tell me how to do it in JQuery or Javascript.
Thanks
//ES5
var res = value.filter(function(e) { return e["RegionName"] != "USA"; })
//ES6
var res = value.filter(e => e["RegionName"] != "USA")
Note: The Arrow function is ES6 syntax.
You just need to filter it out using Array.prototype.filter().
Check out the MDN Docs here
The snippet below filters out USA
let value = [{
"RegionName": "USA",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "8888",
"Country": "USA",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Test",
"Email": "Test#test.com",
"Phone": "9998887777"
}
},
{
"RegionName": "Mexico",
"Contact": {
"LegalName": "somethinglegal",
"StreetAddress": "hello",
"City": "Test",
"State": "Test",
"Zip": "33333",
"Country": "Mexico",
"VAT": "VAT"
},
"EntityContact": {
"LegalName": "Amex",
"Email": "test#test.com",
"Phone": "9998887777"
}
}
];
let newArray = value.filter(arr => arr.RegionName !== 'USA');
console.log(newArray);

Jqgrid - how to reload JQgrid data with new data output based on user form submission?

I have created a search box, which the user enters a name or id in the search form input box and it returns the result . Only problem it works only once.
Here is my HTML below
<button id="basic-search" class="btn btn-default " type="button" > <span class="glyphicon glyphicon-search" aria-hidden="true"></span></button>
<input type="text" id="basicsearchVal" class="form-control" placeholder="Enter text,." autocomplete="on">
I then pass the entered value "searchInput" as a querystring url to the jQgrid
var searchInput = $("#basicsearchVal").val()
SearchData =newURL +"/services-monitor/GetQuickSearch?searchString="+searchInput;
When the user searches, it return the result the first time. but when I try to enter a new name or number in the search form box second time, the jqgrid doesnt seem to update the result, it just show the old result, even though i can see the updated user submitted value is being passed correctly to the JQgrid ajax call.
Only if I refresh the page manually every time it return the result
I also added this as per examples online.:
$(".search-result").jqGrid('setGridParam', { datatype: 'json' }).trigger('reloadGrid');
jQuery(".search-result").trigger("reloadGrid");
what can I do to fix this? why wont JQgrid reload and display the updated results?

I figured out the solution
at first i tried these 2 , which didnt work in my case.
$("#list").setGridParam({datatype:'json', page:1}).trigger('reloadGrid');
$("#list").trigger("reloadGrid", { fromServer: true, page: 1 });
I applied this which worked like a charm, it clear the grid and reload data every time the user searches new data
$(".search-result").jqGrid('GridUnload');
var searchInput = $("#basicsearchVal").val()
if ($('input:text').val().length == 0) {
alert("Please enter a Name to search")
}
else {
$( "#watchlist-b").remove();
$("#watchList-b1").remove();
$("#watchList-b2").remove();
SearchData =newURL +"/services-monitor/GetQuickSearch?searchString="+searchInput;
makeSearchGridAjaxCall (detailPageUrl,SearchData,mydata);
jQuery(".search-result").trigger("reloadGrid");

Filter Records from JSON with Node or ES6

I'm not sure the best way to go about this. I want to iterate my json and find all companies that are in the US for example. This JSON might get way more complex as my app grows too, as in levels, objects, etc. I just want to know ways people are doing simple searching for filtering out subsets of data with JSON and Node.js and/or ES6 or libraries maybe such as Lodash, etc.
So for example this json, what are some ways I can search it and pull back only those companies in the USA?
[{
"id": 0,
"name": "Company1",
"logoUrl": "/lib/assets/company1-logo.png",
"location":{
"country": "USA",
"state": "California",
"city": "Napa"
},
"active": false
},
{
"id": 1,
"name": "Company2",
"logoUrl": "/lib/assets/company2-logo.png",
"location":{
"country": "Germany",
"state": "",
"city": "Berlin"
},
"active": false
},
{
"id": 2,
"name": "Company3",
"logoUrl": "/lib/assets/company3-logo.png",
"location":{
"country": "USA",
"state": "Michigan",
"city": "Detroit"
},
"active": false
}]
Use JavaScript native Array#filter method with ES6 arrow function
var res = data.filter(v => v.location.country === 'USA');
var data = [{
"id": 0,
"name": "Company1",
"logoUrl": "/lib/assets/company1-logo.png",
"location": {
"country": "USA",
"state": "California",
"city": "Napa"
},
"active": false
}, {
"id": 1,
"name": "Company2",
"logoUrl": "/lib/assets/company2-logo.png",
"location": {
"country": "Germany",
"state": "",
"city": "Berlin"
},
"active": false
}, {
"id": 2,
"name": "Company3",
"logoUrl": "/lib/assets/company3-logo.png",
"location": {
"country": "USA",
"state": "Michigan",
"city": "Detroit"
},
"active": false
}];
var res = data.filter(v => v.location.country === 'USA');
console.log(res);
You can use JavaScript's simple .filter() method to return the list of results fulfilling the filter. Say your data is in variable data
ES5
data.filter(function(item) {
return item.location.country === 'USA';
});
ES6: In ES6 you can use arrow functions for same as
data.filter((item) => {
return item.location.country === 'USA';
});
var data = [{
"id": 0,
"name": "Company1",
"logoUrl": "/lib/assets/company1-logo.png",
"location":{
"country": "USA",
"state": "California",
"city": "Napa"
},
"active": false
},
{
"id": 1,
"name": "Company2",
"logoUrl": "/lib/assets/company2-logo.png",
"location":{
"country": "Germany",
"state": "",
"city": "Berlin"
},
"active": false
},
{
"id": 2,
"name": "Company3",
"logoUrl": "/lib/assets/company3-logo.png",
"location":{
"country": "USA",
"state": "Michigan",
"city": "Detroit"
},
"active": false
}];
var res1 = data.filter(function(item) {
return item.location.country === 'USA';
});
const res2 = data.filter((item) => {
return item.location.country === 'USA';
});
console.log(res1);
console.log(res2);
In lodash it will be
_.filter(data, function(item) {
return item.location.country === 'USA';
});
You can use native filter function.
const items = [{
"id": 0,
"name": "Company1",
"logoUrl": "/lib/assets/company1-logo.png",
"location":{
"country": "USA",
"state": "California",
"city": "Napa"
},
"active": false
},
{
"id": 1,
"name": "Company2",
"logoUrl": "/lib/assets/company2-logo.png",
"location":{
"country": "Germany",
"state": "",
"city": "Berlin"
},
"active": false
},
{
"id": 2,
"name": "Company3",
"logoUrl": "/lib/assets/company3-logo.png",
"location":{
"country": "USA",
"state": "Michigan",
"city": "Detroit"
},
"active": false
}]
const usItems = items.filter(v => v.location.country === 'USA')
