需要正则表达式
问题描述：
我有一个文本框，需要通过以下方式进行验证:用户应输入字符，然后输入数字.他们不能同时混淆两者.
例如:
用户不应键入a133bv2、232ds等
必须是abc123
请提供相同的正则表达式.
I have a textbox which needs to be validated in such a way that user should enter characters followed by numbers. They cannot mixup both.
For Eg:
User should not be able to type a133bv2,232ds etc
It must be abc123
Please provide the regular expression for the same.
答
—SA
—SA
^[a-zA-Z]*[0-9]*
如果需要至少一位数字和至少一个字符，请将"*"替换为"+":
If at least one digit and at least one character is required, replace "*" with "+":
^[a-zA-Z]+[0-9]+
