正则表达式问题使用new RegExp与字面量test结果不一致？-灵析社区
你没饰八正则表达式问题使用new RegExp与字面量test结果不一致，new出来是true，使用字面量是false //new new RegExp("^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\\W_]+$)(?![a-z0-9]+$)(?![a-z\\W_]+$)(?![0-9\\W_]+$)[a-zA-Z0-9\\W_]{8,15}$",'g').test("123#kjdsls") //字面量 /^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\\W_]+$)(?![a-z0-9]+$)(?![a-z\\W_]+$)(?![0-9\\W_]+$)[a-zA-Z0-9\\W_]{8,15}$/g.test("123#kjdsls")
LightSea字面量外面没有双引号包括，表达式中的\不需要再次转移
/^(?![a-zA-Z]+$)(?![A-Z0-9]+$)(?![A-Z\W_]+$)(?![a-z0-9]+$)(?![a-z\W_]+$)(?![0-9\W_]+$)[a-zA-Z0-9\W_]{8,15}$/g.test("123#kjdsls")
