Pass variable via ajax to api.php

I am trying to pass a js variable via ajax to the php side. My js code is:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script>
var sAgentId = 'hi'
$.ajax({
url: "api-test.php",
method: "POST",
data : { id:sAgentId}
}).done(function(){
console.log('done')
})
and in the php file, I am trying to get the variable via post:
$sAgentId = $_POST['id'];
But finally in api i get the notification that says
Notice: Undefined index: id in C:\xampp\htdocs\webdev-php-exam-prep\exercise\api-test.php on line 2
Can anyone tell me what I am doing wrong?

Try adding this to your AJAX method:
dataType: "json"
Try also console logging the response back to check $_POST['id'] is being set.
.done(function(data) {
console.log("Data: ", data);
});
and in your PHP just return $_POST['id']

var sAgentId = 'hi'
$.ajax({
url:'api-test.php',
type: "POST",
data: {id: sAgentId },
cache: !0,
dataType: 'json',
success: function(data) {
console.log(data);
}
});

try replace method by type:
type: "POST",

getting api data using getjson javascript

I'm trying to use this api, to show data in my webpage.
I want to fetch the data and display it on a html paragraph.... I am using getJSON, but I couldn't make it work.. I am using AJAX to make a request.
Sample of the json data
{
"status":true,
"data":{
"h1":0,
"h3":0,
"h6":0,
"h12":0,
"h24":0
}
}
getjson code
$.ajax({
type: "GET",
url: "https://api.nanopool.org/v1/eth/avghashrate/1",
dataType: "json",
success: function(data) {
var json = $.parseJSON(data);
$('#results').html( json.data.h1);
}
});
html code is
<div id="results"></div>

Just remove $.parseJSON(), because data is already an object.
$(function() {
$.ajax({
type: "GET",
url: "https://api.nanopool.org/v1/eth/avghashrate/1",
dataType: "json",
success: function(data) {
console.log(typeof data); // -- Object
var json = data;
$('#results').html(json.data.h1);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="results"></div>

JavaScript jQuery AJAX POST data error

I am trying to send a post param. to request.php but it returns that the post param. are empty.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
$.ajax({
url: "request.php",
type: "POST",
data: "{key:'123', action:'getorders'}",
contentType: "multipart/form-data",
complete: alert("complete"),
success: function(data) {
alert(data);
},
error: alert("error")
});

remove " " from this data as data:{key:'123', action:'getorders'}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
$.ajax({
url:"request.php",
type:"POST",
data:{key:'123', action:'getorders'},
contentType:"multipart/form-data",
complete:alert("complete"),
success:function(data) {
alert(data);
},
error:alert("error")
});
</script>

You must use FormData for multipart/form-data ,and also need additional option in ajax ..
var request = new FormData();
request.append('key',123);
request.append('action','getorders');
$.ajax({
url: "request.php",
type: "POST",
data: request,
processData : false,
contentType: false,
success: function(data) {
alert(data);
}
});

This will help you. You don't want a string, you really want a JS map of key value pairs.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
$.ajax({
url:"request.php",
type:"POST",
data:{key:'123', action:'getorders'},
contentType:"multipart/form-data",
complete:alert("complete"),
success:function(data) {
alert(data);
},
error:function(){
alert("error");
});
</script>

This should work like a champ ,
construct object as below and stringify it as JSON.stringify(newObject) then there will be no chance of error
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script>
var newObject= new Object();
newObject.key= '123';
newObject.action='getorders'
$.ajax({
url:"request.php",
type:"POST",
data:JSON.stringify(newObject),
contentType:"multipart/form-data",
complete:alert("complete"),
success:function(data) {
alert(data);
},
error:function(){
alert("error");
});
</script>

Try this:
data: JSON.stringify({key: '123', action: 'getorders'}),
contentType: "application/json"

Ajax Json parsed blank result

I am trying to parse some JSON data through AJAX i followed an example from here:
how to parse json data with jquery / javascript?
On the example, they can get it working, but on my exmaple, the turned blank.
I tried just echoing the php, the JSON displayed with no problem either. Wondering what the problem is.
<!DOCTYPE HTML>
<html>
<head>
<link type ="text/css" rel="stylesheet" href= "css/bootstrap.css">
<link type ="text/css" rel="stylesheet" href= "css/account.css">
</head>
<body>
<p id="result">fefe</p>>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script>
$.ajax({
type: 'GET',
url: 'get.php',
data: { get_param: 'value' },
dataType:'json',
success: function (data) {
var names = data
$('#result').html(data);
}
});
</script>
</body>
</html>
What the JSON result looks like in php:
[{"id":"1","userid":"26","title":"654","description":"654"}]

what is the type of data?
try add this line in your code on success function
success: function (data) {
console.log(data);
}
is it an array of objects, if yes maybe you can try this
$.ajax({
type: 'GET',
url: 'get.php',
data: { get_param: 'value' },
dataType:'json',
success: function (data) {
for(var i=0; i<data.length; i++) {
// do your things here using data[i].description until data[i].userid
}
}
});

Try this
$.ajax({
type: "GET",
dataType: "json",
url: "getjobs.php",
data: data,
success: function(data) {
$('#result').html(data);
}
});

Try setting $.ajax's datatype is set to jsonp. Also try to alert the return value.
$.ajax({
type: 'GET',
url: 'get.php',
data: { get_param: 'value' },
dataType:'jsonp',
success: function (data) {
alert('data is ::' +data);
$('#result').html(data);
}
});

Try this:
$.ajax({
type: 'GET',
url: 'get.php',
data: { get_param: 'value' },
dataType:'json',
success: function (data) {
console.log(data);
}
});
in the console(such as chrome browser`s development tools), you can see the actual result.

How to call json object from AJAX?

Here is my script:
$.ajax({
type: "Get",
url: "Sample.js",
datatype: 'json',
data: JSON.stringify({ key:key }),
success: function (data) {
var sample = data.name;
$("#html").html(sample);
},
error: function () {
alert("Error");
}
});
This is my Sample.js file:
{ "name": "user" }
When I run this code I get a blank screen. This is my script using getJSON():
$.getJSON("Sample.js", function (data) {
var sample = data.name;
$("#html").html(sample);
})
This produces "user" perfectly. What is the problem with $.ajax code?

In the getJSON version your don't send any data. Could this be the reason why that works? To me it looks like this could be sth. on the server side that delivers an empty JSON object when you pass the key parameter.

As the jQuery documentation states:
$.ajax({
dataType: "json",
url: url,
data: data,
success: success
});
Try modifying the dataType param.

change your datatype to dataType. Its case sensitive. Refer http://api.jquery.com/jQuery.getJSON/
Remove JSON.Stringify and change Get to GET
$.ajax(
{ type: "GET",
url: "Sample.js",
dataType: "json",
data: {key:key },
success: function (data)
{ var sample = data.name; $("#html").html(sample); },
error: function () { alert("Error"); }}
);
