Consider the JavaScript Code :
var y= ’’12”;
function f( ) {
var y=’’6”;
alert (this.y);
function g( ) {alert (y); }
g( );
}
f( );
If M is the number of alert dialog boxes generated by this JavaScript code and D1, D2, ....,
DM represents the content displayed in each of the M dialog boxes, then :1
M = 3; D1 displays ”12”; D2 displays ”6”; D3 displays ”12”.
2
M = 3; D1 displays ”6”; D2 displays ”12”; D3 displays ”6”.
3
M = 2; D1 displays ”6”; D2 displays ”12”.
4
M = 2; D1 displays ”12”; D2 displays ”6”.
