JAVASCRIPT FORLOOP EXAMPLES
Example 1: Simple ForLoop
<script>
/*
Syntax:
for(intializ;conditional; increment / decrement)
{
coding
}
*/
for(i=1;i<=5;i++)
{
document.write(i);
}
</script>
Output : 12345
Example 2: ForLoop with Space
<script>
for(i=1;i<=5;i++)
{
document.write(i+" ");
}
</script>
Output: 1 2 3 4 5
Example 3: Multiple Space Using ForLoop
<script>
for(i=1;i<=5;i++)
{
document.write(i+" ");
}
</script>
Output: 1 2 3 4 5
Example 4: Print Data in Next Line Using ForLoop
<script>
for(i=1;i<=5;i++)
{
document.write(i+"<br>");
}
</script>
Output:
1
2
3
4
5
Example 5: ForLoop with Color Formatting
<script>
for(i=1; i<=10; i++)
{
document.write("<font color=red>Number Is:<font><font color=blue>"+i+"</font><br>");
}
</script>
Example 6: star * Pyramid Printing Using ForLoop
<script>
for(i=1;i<=5;i++)
{
for(j=1;j<=i;j++)
{
document.write("* ");
}
document.write("<br>");
}
</script>
Output:
*
* *
* * *
* * * *
* * * * *
Example 7: Pyramid Printing Using ForLoop
<script>
for(i=1;i<=5;i++)
{
for(j=1;j<=i;j++)
{
document.write(j+" ");
}
document.write("<br>");
}
</script>
Output:
1
1 2
1 2 3
1 2 3 4
1 2 3 4 5
Example 8: Descending Numbers using For Loop
<!-- 10 9 8 7 6 5 ...1 -->
<script>
for(i=10; i>=1;i--)
{ document.write(i+" "); }
</script>
Example 9 : ODD Number Printing Using JavaScript
<script>
// 1 3 5 7 9
for(i=1; i<=10;i=i+2)
{
document.write(i+" ");
}
</script>
Example 10 : Even Number Printing Using javaScript
<script>
//0 2 4 6 8 ...
for(i=0; i<=10;i=i+2)
{
document.write(i+" ");
}
</script>
