的格式输入

继承我所拥有的：

/\d{2,3}-\d{3}-\d{4}$/

Answer 1

蛮力/易于维护/易于阅读/我认为就是你所拥有的。

(\d\d\d\-\d\d\d\-\d\d\d\d)|(\(\d\d\d\)\-\d\d\d\-\d\d\d\d)|(\d\d\-\d\d\d\-\d\d\d\d)|(\d\d\d\d\d\d\d\d\d)

或者如果您愿意：

(\d{3}\-\d{3}\-\d{4})|(\(\d{3})\-\d{3}\-\d{4})|(\d{2}-\d{3}\-\d{4})|(\d{9})

Answer 2

((\d{2,3}|\(\d{3}\))-\d{3}-\d{4}|\d{9})

Answer 3

大多数情况下，你关心的是数字：

    /^([()-]*\d)[()-]*){9,10}$/.test(string);

    or even

    /^(\D*\d\D*){9,10}/.test(string);
