$(document).ready(function(){
// Ajax request to retrive data
function showData(){
$.ajax({
url:"retrieve.php",
method:"GET",
datatype: "json",
success: function(data){
// console.log(data);
if(data){
x = data;
}else {
x = "";
}
for(i = 0; i < x.length; i++){
console.log(x[i].name);
}
},
});
}
showData();
Why line#17 is showing as undefined?
When execution gets to the for loop, what is the value of x?
That’s not what I meant.
When you actually run the code, what does console.log show is the value of x?
x is never being set as far as I can see (let x; or var x;)
This one →
That means X
is set correctly, and we have value in data(=x) object
.
P.S. → I have disabled any other console.log
Also ajax is retrieving things from retrive.php:
include 'dbConnection.php';
$sql = "SELECT * FROM studebts";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
$data = array();
while ($row = $result->fetch_assoc()) {
$data[] = $row;
}
}
// Returning JSON Format
echo json_encode($data);
Problem was datatype
vs dataType
Fixed!
