示例
下面的示例使用Exit For。 如果计数器的值达到 4,则退出 For 循环,并且控制立即跳转到 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>
当执行上述代码时,它会在控制台中打印以下输出。
The value is i is : 0 The value is i is : 2 The value is i is : 4 The value is i is : 40
