Following JSON data comes from php,
I have tried following code. But console displays undefined error.
jQuery.each(result.address, function(obj) {
console.log(obj.city);
});
EDIT : Also it's not working and throwing undefined error.
jQuery.each(result.address, function(obj) {
console.log(obj[0].city);
});
It is working : console.log(result.address.address1.city);. But in this case address1 is not fixed. eg. result.address.xyz.city, result.address.abc.city
You're calling city on each address, while cities are inside addressX inside address. Try:
jQuery.each(result.address, function(key, val) {
console.log(val.city);
});
jsfiddle DEMO
Maybe in this way:
for (i = 0; i < result.address.length; i++) {
console.log(result.address[i].city);
}
I'm not sure if jquery.each works in this case.
I hope it helps.
Javascript
var dictionary = {
"12Jan2013": [{
"id": "0",
"name": "ABC"
}, {
"id": "1",
"name": "DEF"
}],
"13Jan2013": [{
"id": "0",
"name": "PQR"
}, {
"id": "1",
"name": "xyz"
}]
};
for (var i in dictionary) {
dictionary[i].forEach(function(elem, index) {
console.log(elem, index);
});
}
Output
Object {id: "0", name: "ABC"} 0
Object {id: "1", name: "DEF"} 1
Object {id: "0", name: "PQR"} 0
Object {id: "1", name: "xyz"} 1

i have a return like this
[
{
"tripw3": "1"
},
{
"tripw1": "2"
},
{
"tripw1": "3"
},
{
"tripw2": "4"
},
{
"tripw2": "5"
},
{
"tripw3": "6"
},
{
"tripw3": "7"
}]
and I want to make the above result be
[
{
tripw3: ["1", "6", "7"],
tripw2: ["4", "5"],
tripw1: ["3", "2"]
}]
Until now I'm still confused to make this happen.
You cane easily acheve the result using reduce, Object.keys and forEach
const arr = [
{
tripw4: "1",
},
{
tripw4: "2",
},
{
tripw4: "3",
},
{
tripw4: "4",
},
{
tripw4: "5",
},
{
tripw4: "6",
},
{
tripw4: "7",
},
];
const result = [arr.reduce((acc, curr) => {
Object.keys(curr).forEach((k) => acc[k] ? acc[k].push(curr[k]) : (acc[k] = [curr[k]]));
return acc;
}, {})];
console.log(result);

I have the following array of objects:
[
{
"messages": {
"m1": {
"message": "Relay malfunction found. Cause: moth.",
"sender": "ghopper"
}
},
"title": "Historical Tech Pioneers",
"key": "one"
} ]
But I wish to convert it to an array of arrays. For example: I want to turn the title field below:
"title": "Historical Tech Pioneers"
Into:
"title": [ "Historical Tech Pioneers" ]
Thank you for your help
Assuming the declaration:
var myArr = [
{
"messages": {
"m1": {
"message": "Relay malfunction found. Cause: moth.",
"sender": "ghopper"
}
},
"title": "Historical Tech Pioneers",
"key": "one"
}
];
You can iterate over each element and reassign the property using:
myArr.forEach(o => o.title = [o.title]);
Or without ES6:
myArr.forEach(function (o) {
o.title = [o.title]);
});

I have this response from a $.getJSON call. Now I want to select the name property of the object with "selected": true, and print it to a div with id charTitle.
"titles": [{
"id": 17,
"name": "Sergeant %s"
}, {
"id": 53,
"name": "%s, Champion of the Naaru"
}, {
"id": 64,
"name": "%s, Hand of A'dal",
"selected": true
}]
You can achieve this with a simple loop:
for (var i = 0; i < obj.titles.length; i++) {
if (obj.titles[i].selected) {
$('#charTitle').text(obj.titles[i].name);
}
}
Example fiddle
Or with jQuery's $.each():
$.each(obj.titles, function(i, title) {
if (title.selected)
$('#charTitle').text(title.name);
});
Note that if you have multiple objects in the array with selected set to true you would need to use append() instead of text() to set the content of the div, otherwise the previous value will be overwritten.
using underscore you can get this with
var titles = ...
_.findWhere(titles, {selected: true});
see http://underscorejs.org/#findWhere
Try using Array.prototype.filter()
var arr = [{
"id": 17,
"name": "Sergeant %s"
}, {
"id": 53,
"name": "%s, Champion of the Naaru"
}, {
"id": 64,
"name": "%s, Hand of A'dal",
"selected": true
}]
var res = arr.filter(function(val, key) {
return val.selected === true
})[0].name;
$("#charTitle").html(res)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js">
</script>
<div id="charTitle"></div>

When I type Monday and click Search I want to get all of Monday's JSON data and not just the first row. I've tried modifying the forEach function and also using two ng-repeats in html. So I guess it's the JSON Data structure?
Fiddle.
"Monday": [{
"Name": "John",
"Address": "Street",
"Phone": "111",
"Status": "Sleep"
},
{
"Name": "Sam",
"Address": "Street2",
"Phone": "2",
"Status": "Awake"
}
],
"Tuesday": [{..............................
You need to use this code:
angular.forEach($scope.items, function (value, key) {
if (key === enteredValue) {
angular.forEach(value, function(item) {
$scope.results.push({
name: key,
address: item.Address,
phone: item.Phone,
status: item.Status
});
});
}
});
The problem was that you only used one forEach, when you actually need two. Not a problem with your data structure.
You could also just do this, however:
angular.forEach($scope.items[enteredValue], function (item, key) {
$scope.results.push({
name: enteredValue,
address: item.Address,
phone: item.Phone,
status: item.Status
});
});
which would be must simpler. I hope this helps!

This is probably a very easy question but let's say I have a php json_encoded javascript object of this form:
var js_objet = {
"1": {
"Users": {
"id": "14",
"name": "Peter"
},
"Children": [
{
id: 17,
name: "Paul"
},
{
id: 18,
name: "Mathew"
}
]
}
}
What is the synthax to get the name of the child with id 18 (Mathew) for example from that Object?
Thank you
Here's such a custom function as mentioned earlier.
function getChildrenById(id){
for (var child in js_objet[1].Children){
if(id == js_objet[1].Children[child].id){
return js_objet[1].Children[child].name;
}
}
return false;
}
running getChildrenById(18) would return "Mathew"
Hope that helps,
R.
You can do it like this:
var name = js_objet["1"].Children[1].name;
JSFiddle available here
This is how I would approach this problem:
var id = 18;
var name = '';
var jsObjIndex = "1";
var jsObjAttr = "Children"
for (var i = 0; i < js_objet[jsObjIndex][jsObjAttr].length; i++)
{
if (js_objet[jsObjIndex][jsObjAttr][i].id == id)
{
name = js_objet[jsObjIndex][jsObjAttr][i].name;
break;
}
}
You are basically performing a linear search on every element of jsObjIndex.Children. There are likely better solutions however :).
This really is a comment, but I don't have enough reputation (but it's relevant as I recently encountered the same issue): This would probably be easier to do if you can change the JSON format to use the ID as the key for each child object:
var js_objet = {
"1": {
"Users": {
"id": "14",
"name": "Peter"
},
"Children": {
"17":{
"name": "Paul"
},
"18":{
"name": "Mathew"
}
}
}
}
Then you can simply call it using
js_objet[1].Children[18].name;
This is assuming each ID is unique.
