我目前在js中使用以下正则表达式进行电子邮件验证， 其中电子邮件地址可以用逗号分隔或 分号。然而，问题在于我可以输入两封电子邮件 （作为连续播放，没有逗号或分号），只要它以 $ b $结尾b三个字符域，它被认为是有效的。 我想知道是否有办法制作逗号或分号 如果是第二封电子邮件必须地址已存在？ 非常感谢任何帮助 - 路易斯 这是脚本： function checkEmailForErrors（表格，字段）{ var emailFilter2 = /（（[a-zA-Z0-9 \-？\。？] +）@（（[a-zA-Z0-9 \\ \\ -_] + \。）+）（[az] {2,3}）（\ W？[，;] \ W？（？！$））？） + $ / i; var emailValue2 = eval（" document。" + Form +"。" + Field +" .valu e"）; if（！（emailFilter2.test（emailValue2）））{ 返回false; } else { 返回true; } }

Hi, I currently am using the following regex in js for email validation, in which the email addresses can be separated by commas or semicolons. The problem, however, lies in that I can type two emails (as a run-on, with no comma or semicolon), and as long as it ends in a three character domain, it is accepted as valid. I wonder if there would be a way to make the comma or semicolon mandatory if a second email address existed? Many thanks for any help - Louis Here is the script: function checkEmailForErrors (Form,Field) { var emailFilter2=/(([a-zA-Z0-9\-?\.?]+)@(([a-zA-Z0-9\-_]+\.)+)([a-z] {2,3})(\W?[,;]\W?(?!$))?)+$/i; var emailValue2=eval("document."+Form+"."+Field+".valu e"); if (!(emailFilter2.test(emailValue2))) { return false; }else{ return true; } }

））？）+

/ i; var em ailValue2 = eval（" document。" + Form +"。" + Field +" .valu e"）; if（！（emailFilter2.test（emailValue2）））{ 返回false; }否则{ 返回true; } } /i; var emailValue2=eval("document."+Form+"."+Field+".valu e"); if (!(emailFilter2.test(emailValue2))) { return false; }else{ return true; } }

您可以尝试使用以下正则表达式： /^ [A-Z0-9 \。 ％ - ] + @ [A-Z0-9\ .-] + \ [AZ] {2,4}（：（：？[;] [A-Z0-9\ ._％ - ] + @ [A- Z0-9 \ .-] +））？ You can try to use the following regular expression: /^[A-Z0-9\._%-]+@[A-Z0-9\.-]+\.[A-Z]{2,4}(?:(?:[,;][A-Z0-9\._%-]+@[A- Z0-9\.-]+))?
