javascript - XMLHttpRequest readyState is equal to 0 -

-

I can not find any data with XMLHttpRequest, because its return location returns 0. I have this code: 

  Function chargerresendiments () {var xhrArrond = new XMLHttpRequest (); Exhausted.OndestateBangze = Charger Around Callback (Exor Arrayed); Var lienDocArrond = 'PHP / script_load_arrondissements_get.php'; ExhaRndand.Open ('GET', Leon Dockerend, True); Console.log ('Arrangement Charges Dan's Le Fisher XML'); XhrArrond.send (zero); } Function charger Aroundcodeback (warning) {Warning (excerpt. Fredstate); }

The warning window shows 0. I tried to open XHR before setting the handler, but still returned 0. Now, the strange thing is that I have several XHRs on that page, and they all work very well, leaving one, and why I can not explain

BTW, my PHP path The path is: http: //localhost/TP2/PHP/script_load_arrondissements_get.php .

In addition, you should know that this file gives a correct XML content.

This console says about my request: Enter the image here

Nobody knows what can be the problem? Thank you. 

  xhrArrond.onreadystatechange = chargerArrondCallback (xhrArrond);

You are calling your event handler function and designating your return value ( undefined ) as the event handler.

Change it to: 

  Exhausted.OndestateBenz = ChargerArandandCallback;

... and then access the XHR object which is associated with this inside the function

In advance thank you If you have created a true asset in your class then You should be a great and setter, you can add the code directly to the form property in order to take action on the basis of "form": Public partial category Form 1: form {public form 1 () {InitializeComponent (); } // define car square public class car {public string name = string. Empty; } // private car to keep the value of the current car private variable _car = null; // Property of public form which you can ru...
