web worker - XMLHttpRequest.send crashes browser -

-

Crash this code () - only when the caller is called in the web worker. Runs fine in the main thread. 

  var xhr = new XMLHttpRequest (); Xhr.open ('GET', "http: // localhost: 62178 / document?" + Msg.url, incorrect); Xhr.setRequestHeader ('content-type', 'app / jason'); Var worker = this; Xhr.onreadystatechange = function () {// ...}; Xhr.send ();

Any console output, only one browser crash

open Required: 

  xhr.open ('GET', "http: // localhost: 62178 / document?" + Msg.url, true);

Async should be set to true in a web worker.
