Question

다음 코드를 시도했지만 전체 화면에서 작동하지 않습니다.

public static native void hello1() 
/*-{ 
    var body=$doc.getElementsByTagName("body")[0]; 
var posx=0; 
    var posy=0; 

    body.addEventListener("click",function (e) 
     { 
    if (e.clientX ||e.clientY) 
     { 
      posx = e.clientX; 
      posy = e.clientY; 
     } 
alert('Mouse position is: X='+posx+' Y='+posy);  
    }); 
}-*/; 

Answer 1

public static native void hello1() 
/*-{ 
var body=$doc.getElementsByTagName("body")[0]; 
var posx; 
var posy; 

    $wnd.addEventListener("click",function (e) 
    { 
    if (!e) var e = $wnd.event; 
if (e.pageX || e.pageY) 
{ 
    posx = e.pageX; 
    posy = e.pageY; 
} 
else if (e.clientX ||e.clientY) 
     { 
      posx = e.clientX+$doc.body.scrolleft+$doc.scrollleft; 
      posy = e.clientY+$doc.body.scrolltop+$doc.srolltop; 
     } 
alert('Mouse position is: X='+posx+' Y='+posy);  
    }); 
    }-*/;
