Hi there,
I have some questions for an assignment that I can't figure out. If anyone
could be of assistance that would be much appreciated.
1)Which instruction will change the background colour of an element?
A document.getElementById("t").backgroundColor = "yellow"
B document.getElementById("t").bgcolor = "yellow"
C document.getElementById("t").style.backgroundColor = "yellow"
D document.getElementById("t").style.color = "yellow"
2)
Which are the valid 'for' statement(s)
A for x = 1 to 10
B for(x=0; x<10; x++)
C for(x=0, y=10; x<10; x++, y--)
D for(x=0, x<10, x++)
3)
Which are the INCORRECT math equations
A a =+ 20;
B a = a + 20;
C a = 20 / 4;
D a++;
E a != 30;
F a =* 4;
G a = 3;
4)
Which are the preferred methods to use when Javascript has been disabled ?
A <noscript></noscript>
B <a href="#" onCick=myFunction();">Show Page</a>
C <a href="page1.htm">Show Page</a>
D <a href="page1.htm" onCick=myFunction();">Show Page</a>
5)
An array can be initialised by
A var a = new Array("ab","b","c");
B var a = ["a","b","c"];
C var a = ("a","b","c");
D var a = a["a","b","c"];
6)
When you tab into a form control (i.e. a textbox) what event is executed
A onMouseOut
B onClick
C onBlur
D onFocus
7)
What syntax is needed to initalise a Regular Expression
A var re = RegExp();

8)
What does the following function dofunction
x(y){document.getElementById(y).style.display;a = (z=='block') ? 'none' :
'block';z.a;}
