只要条件为false，当我们要重复一组语句时，就会使用Do..Until循环语句。 条件可以在循环开始时或循环结束时检查。
VBScript中Exit For Statement的语法是：
Exit For
以下示例使用Exit For。如果Counter的值达到4，则退出For循环，并且控制跳转到For循环之后的下一条语句。
<!DOCTYPE html> <html> <body> <script language = "vbscript" type = "text/vbscript"> Dim a : a = 10 For i = 0 to a Step 2 'i is the counter variable and it is incremented by 2 document.write("The value is i is : " & i) document.write("<br></br>") If i = 4 Then i = i*10 'This is executed only if i = 4 document.write("The value is i is : " & i) Exit For 'Exited when i = 4 End If Next </script> </body> </html>
执行上述代码后，它将在控制台中输出以下输出。
The value is i is : 0 The value is i is : 2 The value is i is : 4 The value is i is : 40
