Consider this simple attempt to find a value in an object:
var config = {
product1: {
ids: ['master']
},
product2: {
ids: ['ps1', 'ps2']
}
};
var id = 'ps2';
var slotID = 'master';
var categorySlotIds = config[slotID].ids;
categorySlotIds.find(id);
I get: TypeError: Cannot find function find in object product1, product2
If I do typeof(categorySlotIDs) the result is object.
The manual for find says: The find() method returns the first element in the provided array
What gives?

Sending data from javascript to php isn't working: Result null [closed]

So my javascript file looks like this:
$(document).ready(function() {
var map = {
url: window.location.pathname //get URL without domain
};
$.post("/php/SongOutput.php", {map}).done(function(data){
console.log(map); //Check that the map is correct
console.log(data); //Show the value of $_POST["url"];
})
});
And the bit of php is the following:
echo $_POST["url"];
Now, as you can see what I'm trying to do is sending the current url of the site to php. But the only output I get from console.log(data); is null. How can I fix this?

you need to remove {} from second argument
$.post("/php/SongOutput.php", map).done(function(data){
console.log(map); //Check that the map is correct
console.log(data); //Show the value of $_POST["url"];
})

Good day everyone,
I'm trying to convert the dates from my api using moment.js From my api, I have this kind of sample collection
I'm getting the same date like 2019-12-13 in all my dates.
Note: The problem is not in moment since it is working fine in my other codes. Just the forEach and I don't know which causes the problem.
const response = {
data: [{
'from': '2019-12-31T00:00:00',
'to': '2020-12-31T00:00:00'
},
{
'from': '2021-12-31T00:00:00',
'to': '2022-12-31T00:00:00'
},
{
'from': '2023-12-31T00:00:00',
'to': '2024-12-31T00:00:00'
}
]
}
response.data.forEach((d) => {
d.from = moment(response.data.from).format("YYYY-MM-DD")
d.to = moment(response.data.to).format("YYYY-MM-DD")
})
console.log(response.data)
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.24.0/moment.min.js"></script>

You aren't using d in your forEach loop - use d.to and d.from not response.data.to and response.data.from:
response.data.forEach((d)=>{
d.from = moment(d.from).format("YYYY-MM-DD")
d.to= moment(d.to).format("YYYY-MM-DD")
});

Hi I'm trying to print a list in which every entry should look like "element X of TOTAL" but instead of TOTAL i get only blank text.
I fell like it's something stupid but i can't figure out what.
This is from my html
<li ng-repeat="elem in lista" ng-show="check">
Elemento {{elem.item}} di {{len}}
<button ng-click="remove(elem)">Remove</button>
</li>
and here is from my app.js, which includes my controller
$scope.lista = [
{ item: 'uno' },
{ item: 'due' },
{ item: 'tre' }
];
var len = $scope.lista.lenght;

Change
var len = $scope.lista.lenght;
To :
$scope.len = $scope.lista.length;

var data = {};
data.info.id = "alpha";
This logs to the console: "TypeError: data.info is undefined".
Well that's great and all but I need to store a value in data.info.id. Isn't that what objects are supposed to do?
This should produce an object that looks like this:
data: {
info: {
id: "alpha"
}
}
Is data.info = {} really a necessary step?
In response to Patrick Evans - that's an unrelated question.

Well there is another way. That's putting the info-object directly in the data-object like this:
var data = {
info: {}
}
data.info.id = "alpha";
console.log(data);
