Ok... This time I want giving you tutorial "javascript" about "statement"...
In javascript to be found Two statement...
1. Conditional
- IF
- IF - ELSE
- IF - ELSE IF - ELSE
- SWITCH
2. Looping
- FOR
- WHILE
1. Conditional
Conditional is statement for correct coding in order to have two result "true" or "false"... And If conditional "true" Program want continue.. And if "false" program want stop or return, until result "true"..
A.IF
Sintaks :
if (conditional)
{
True Result
}
Example :
Copy This Cding your aplication
<html>
<head>
<title>Statement For Newbie</title>
</head>
<body>
<script>
var x = 10;
if (x == 10)
{
alert("Yes.. Number is 10");
}
</script>
</body>
</html>
And if done.. save with safe as type "HTML"..
And Double click...
This Result :
B. IF - ELSE
Sintaks :
If (conditional)
{
Coding Is True
}
else
{
Code Is False
}
Example:
Copy This Cding your aplication
<html>
<head>
<title>Statement For Newbie</title>
</head>
<body>
<script>
var x =5;
if (x == 7)
{
alert("The Number is 7)
}
else
{
alert("The Number is Not 7)
}
</script>
</body>
</html>
And if done.. save with safe as type "HTML"..
And Double click...
This Result :
C. IF - ELSE IF - ELSE
Sintaks:
If(conditional 1)
{
Code Number 1 Is True
}
else if(conditional 2)
{
Code Number 2 Is True
}
else(conditional 3)
{
Code Number 3 Is True
}
Example:
Copy This Cding your aplication
<html>
<head>
<title>Statement For Newbie</title>
</head>
<body>
<script>
var x = 89;
if (x >= 85)
{
alert("A")
}
else if (x >= 65)
{
alert("B")
}
else (x >= 40)
{
alert("C")
}
</script>
</body>
</html>
And if done.. save with safe as type "HTML"..
And Double click...
This Result :
D. SWITCH
Switch is Statement Avail if to be found many conditional.. Likely "IF"
Sintaks:
switch(expression)
{
case conditional_1:
Code Number 1 Is True;
break;
case conditional_2:
Code Number 2 Is True;
break;
case conditional_3:
Code Number 3 Is True;
break;
}
Example:
Copy This Cding your aplication
<html>
<head>
<title>Statement For Newbie</title>
</head>
<body>
<script>
var x = "2";
switch (x)
{
case "1":
alert("Number 1");
break;
case "21":
alert("Number 2");
break;
case "3":
alert("Number 3");
break;
}
</script>
</body>
</html>
And if done.. save with safe as type "HTML"..
And Double click...
This Result :
1. Looping
Looping is statement was present by javascript for more eazy in alogaritma... Usually statement for was have value... and want to be continue until conditional to fill..
A. FOR

<body>
<script>
for (a = 1; a <= 10; a++)
{
document.write(" We are Knowledge ");
}
</script>
</body>
</html>
And if done.. save with safe as type "HTML"..
And Double click...
This Result :
A. WHILE

sintaks:
while(conditional)
{
We Are Knowledge
}

Copy This Cding your aplication
<html>
<head>
<title>Statement For Newbie</title>
</head>
<body>
<script>
var a = 0;
while(a <= 5)
{
document.write("We Are Knowledge"+"<br/>");
a++;
}
</script>
