Loops allow you to execute the same section of code again and
again thereby saving you time and cutting down on the amount of code you have to write. VBscript has 2 main types of loops.
The For...Next loop lets you specify the number of times you want the loop to execute.
<%
For i=1 to 5 ' use
i as a counter
response.write i & "<br>"
next 'repeat the
code and move on to the next value of i
%>
The code prints out 1 to 5, the <br> tag puts a line break in between each value;
1The Do...Loop allows you to loop while a condition is true or until a condition becomes true
<%
'first of all assign a value to i
i=1
Do While i<9
response.write i & "<br>"
i=i+1 'increment the value
of i for next time loop executes
Loop
%>
What the above code does is simply print out the following;
1<%
'first of all assign a value to i
i=1
Do Until i=9
response.write i & "<br>"
i=i+1 'increment the value
of i for next time loop executes
Loop
%>
Again What the above code does is simply print out the following;
1If you want to exit the loop then VBscript allows you to;
<%
For i=1 to 100
response.write i & "<br>"
If i= 99 Then Exit For 'just
before 100 is printed out the loop is exited
Next
%>
