我的表格上有一个电话号码的盒子。 我的定期表述是相当普遍的,可以接受当地或国际电话数量几乎每一种变动。 表达方式如下:
^(+)? [1-9]{1,2}? ([s.])? ((d{1,4}) ́{1,4} ([-s.])? 美元
问题是,这个领域并不需要,但如果它们决定进入一个编号,则需要加以验证。 是否有这样做的可能方式?

除^
和>外,随附<条/条码>,<>
^(((+)?[1-9]{1,2})?([-s.])?(((d{1,4}))|d{1,4})(([-s.])?[0-9]{1,12}){1,2}(x?[0-9]{1,})?)?$
我没有参加协会的方案拟订工作,但你可以做某种条件,如:
if( textbox.value.length > 0 ) then validate
因此,只有在用户进入某件事时,才会验证。
