如何在仅接受字母数字字符的文本框上应用验证 [英] how to apply validation on textbox that only accepts alphanumeric characters

问题描述

如果用户只输入字符或仅输入数字或任何特殊字符，我想在仅接受字母数字字符的文本框上应用验证，则应显示仅允许使用字母数字字符的错误消息。如果用户输入少于6个字符或大于10个字符的字符，则密码长度应至少为6个字符，最大长度为10个字符，则错误消息显示密码长度必须至少为6个字符且不得为10个字符.plzzzz

推荐答案

它不是那样的工作。

我们不为你工作。

如果你想要别人写你的代码，你必须付钱 - 我建议你去Freelancer.com并在那里问。



但要注意：你得到了你付出的代价。支付花生，买猴子。

It doesn't quite work like that.
We do not do your work for you.
If you want someone to write your code, you have to pay - I suggest you go to Freelancer.com and ask there.

But be aware: you get what you pay for. Pay peanuts, get monkeys.
