Question

字符串是否同时含有大小写字母和数字如题，正则表

Answer 1

采用逆向思路来写，虽然长，但也不是长得不可接受，如下：^(?:(?!a[ac-z]|b[abd-z]|c[a-ce-z]|d[a-df-z]|e[a-eg-z]|f[a-fh-z]|g[a-gi-z]|h[a-hj-z]|i[a-ik-z]|j[a-jl-z]|k[a-km-z]|l[a-ln-z]|m[a-mo-z]|n[a-np-z]|o[a-oq-z]|p[a-pr-z]|q[a-qs-z]|r[a-rt-z]|s[a-su-z]|t[a-tv-z]|u[a-uw-z]|v[a-vxyz]|w[a-wyz]|x[a-xz]|y[a-y]|z[a-z]|0[02-9]|1[013-9]|2[0-24-9]|3[0-35-9]|4[0-46-9]|5[0-57-9]|6[0-689]|7[0-79]|8[0-8]|9[0-9])[a-z\d])+$
