Echo Json_encode back to the JSON object, but the front end gets a string instead of a JSON object

Echo Json_encode Returns a JSON object, but instead of a JSON object, it gets a string in the front-end
Front end use code to submit and process subsequent results

Function del (ID) {
      if (Confirm (' Confirm to delete this keyword? ')){
$.post ('./keyword ', {op: ' del ', Id:id},function (Result) {
alert (result); Normal This section should show the Object:object, but now the display is a string
if (Result.code! = 0) {
Alert ("Delete failed! ");
}else{
Location.reload ();
}
});
}
}

The service side uses the following code to return

echo Json_encode (Array ("code" =>0));
Exit

Normally in front of the alert result this variable should be shown as object:object, but this JSON string is now displayed.
