在注册一些网站的时候会要求输入邮箱，以注册支付宝辩尺穗为例，如果邮箱输入不正确就无法注册：1、进入支付宝的邮箱注册页面/iknow-pic.cdn.bcebos.com/a50f4bfbfbedab640acda58bf936afc379311e39"target="_blank">/iknow-pic.cdn.bcebos.com/a50f4bfbfbedab640acda58bf936afc379311e39?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"wqktp="困空https://iknow-pic.cdn.bcebos.com/a50f4bfbfbedab640acda58bf936afc379311e39"/>2、在邮箱的位置随便输入一些字母，然后会马上提示邮箱格式不正确/iknow-pic.cdn.bcebos.com/8c1001e93901213f2abda6975ae736d12e2e95eb"target="_blank">/iknow-pic.cdn.bcebos.com/8c1001e93901213f2abda6975ae736d12e2e95eb?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"wqktp="https://iknow-pic.cdn.bcebos.com/8c1001e93901213f2abda6975ae736d12e2e95eb"/>3、但是当输入正确的邮箱格式就不会提示携卜了，比如123456@qq.com。如果您有qq的话，qq邮箱就是您的qq号后面加上@qq.com，假设您的qq是123456，您的qq邮箱就是123456@qq.com。/iknow-pic.cdn.bcebos.com/e824b899a9014c085c47c3ee047b02087bf4f479"target="_blank">/iknow-pic.cdn.bcebos.com/e824b899a9014c085c47c3ee047b02087bf4f479?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"wqktp="https://iknow-pic.cdn.bcebos.com/e824b899a9014c085c47c3ee047b02087bf4f479"/>
