我可以验证IP地址192.168.120.1 [英] Can I verify ip address 192.168.120.1

问题描述

我开发了用于为计算机，打印机，路由器，交换机，摄像头和IP电话分配IP地址的表单。当用户输入类似192.168.120.1的IP地址时，这里有ip地址192,168,120和1的四个部分。我可以验证0-255范围内的每个部分吗？如何验证？

还必须输入所有四个部分。


谢谢和问候，

Vikas

And also that all four part must be entered.

推荐答案

首先将ip地址存储在一个变量''str''


试试这个功能

First store that ip address in one variable ''str''

try this function

是的，女士，你很棒。


工作正常。这里只需要很少的修改。如果发现超出范围，则光标应保留在同一字段上。所以我添加了行

Yes madam, you are great.

It is working fine. Here only little modification requires. If found out of range, then cursor should remain on same field. So I added line
