Angular.js中字母数字的正则表达式 [英] Regular expression for alphanumeric in Angularjs

问题描述

我想要一个用于angularJS中字母数字字符的正则表达式，我已经尝试过一些正则表达式，例如(\ d [a-z])"，但它们只允许我输入数字和字母.但是我想要一个正则表达式，不允许我输入它们.

I want a regex for alphanumeric characters in angularJS, I've tried some regex like "(\d[a-z])" but they allow me to enter only number as well as only alphabets. But I want a regex which won't allow me to enter them.

示例: 121232，abchfe，abd()*，42232 ^ 5 $ 是无效输入的示例. 12fUgdf，dGgs1s23 是一些有效输入.

Example: 121232, abchfe, abd()*, 42232^5$ are some example of invalid input. 12fUgdf, dGgs1s23 are some valid inputs.

推荐答案

此解决方案要求至少一个(a-z，A-Z和0-9)之一:

This one requires atleast one of each (a-z, A-Z and 0-9):

^(?=.*[0-9])(?=.*[a-z])(?=.*[A-Z])([a-zA-Z0-9]+)$
