从外部站点检索数据

Question

I would like to get some values from an external site that is loaded using js functions. Until now i have tried something like i this but im sure is not the correct way

window.location = "http://dashboard.monitis.com/sharedPage.jsp?tI=OHIHg3S9XiBj70SNtIGi0g%253D%253D&uI=hGCXtzJFZF0M2GGYsvfYunNBx3EZykTidEFveqU24IY%253D";


x = document.getElementsByClassName('x-grid3-cell-inner x-grid3-col-1')[0].textContent;

alert(x);

Answer 1

window.location will redirect your browser to that location, so the rest of your script is never executed. You probably want to fetch the contents of that url using an ajax request and then do something with that content.

xhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    console.log(this.responseText);
  }
};
xhttp.open("GET", "http://dashboard.monitis.com/sharedPage.jsp?bla..bla", true);
xhttp.send();
