推荐答案

首先将所有逗号替换为分号，然后使用..
如果str包含您的电子邮件名字符串，那么..

first you replace all comma to semicolon and then use..
if str conatins you emailname string then..

var emails
str = str.replace(",",";");
emails = str.split(";")

现在emails变量包含您的所有电子邮件ID ...

now emails variable contains your all email ids...

您好，请尝试以下

< asp:button id ="btnSendInvite" runat ="server" onclientclick ="Javascript:return VerifyEmail();" text =立即发送邀请"/>

< script type ="text/javascript">

函数VerifyEmail(){
var ids = document.getElementById(''txtInvtMember'').value


myArray = ids.split(''，'');
var i;
for(i = 0; i< myArray.length; i ++){
var emailID = trim(myArray [i]);
if(echeck(emailID)== false){返回false}
}
返回true
}

函数echeck(str){

var at ="@"
var dot =."
var lat = str.indexOf(at)
var lstr = str.length
var ldot = str.indexOf(dot)
如果(str.indexOf(at)== -1){
alert(无效的电子邮件ID:" + str)
返回false
}

if(str.indexOf(at)== -1 || str.indexOf(at)== 0 || str.indexOf(at)== lstr){
alert(无效的电子邮件ID:" + str)
返回false
}

if(str.indexOf(dot)== -1 || str.indexOf(dot)== 0 || str.indexOf(dot)== lstr){
alert(无效的电子邮件ID:" + str)
返回false
}

if(str.substring(lat-1，lat)==点|| str.substring(lat + 1，lat + 2)==点){
alert(无效的电子邮件ID:" + str)
返回false
}

if(str.indexOf(dot，(lat + 2))== -1){
alert(无效的电子邮件ID:" + str)
返回false
}

if(str.indexOf(")！= -1){
alert(无效的电子邮件ID:" + str)
返回false
}

返回true
}

功能修剪{
返回rtrim(ltrim(s));
}

函数ltrim(s){
var l = 0;
而(l< s.length && s [l] =='''')
{l ++; }
返回s.substring(l，s.length);
}

函数rtrim(s){
var r = s.length-1;
while(r> 0 && s [r] =='''')
{r-= 1; }
返回s.substring(0，r + 1);
}

</script>

Hi try below

<asp:button id="btnSendInvite" runat="server" onclientclick="Javascript:return VerifyEmail();" text="Send Invite Now" />

<script type="text/javascript">

function VerifyEmail() {
var ids = document.getElementById(''txtInvtMember'').value


myArray = ids.split('','');
var i;
for (i = 0; i < myArray.length; i++) {
var emailID = trim(myArray[i]);
if (echeck(emailID) == false) { return false }
}
return true
}

function echeck(str) {

var at = "@"
var dot = "."
var lat = str.indexOf(at)
var lstr = str.length
var ldot = str.indexOf(dot)
if (str.indexOf(at) == -1) {
alert("Invalid E-mail ID: " + str)
return false
}

if (str.indexOf(at) == -1 || str.indexOf(at) == 0 || str.indexOf(at) == lstr) {
alert("Invalid E-mail ID: " + str)
return false
}

if (str.indexOf(dot) == -1 || str.indexOf(dot) == 0 || str.indexOf(dot) == lstr) {
alert("Invalid E-mail ID: " + str)
return false
}

if (str.substring(lat - 1, lat) == dot || str.substring(lat + 1, lat + 2) == dot) {
alert("Invalid E-mail ID: " + str)
return false
}

if (str.indexOf(dot, (lat + 2)) == -1) {
alert("Invalid E-mail ID: " + str)
return false
}

if (str.indexOf(" ") != -1) {
alert("Invalid E-mail ID: " + str)
return false
}

return true
}

function trim(s) {
return rtrim(ltrim(s));
}

function ltrim(s) {
var l = 0;
while (l < s.length && s[l] == '' '')
{ l++; }
return s.substring(l, s.length);
}

function rtrim(s) {
var r = s.length - 1;
while (r > 0 && s[r] == '' '')
{ r -= 1; }
return s.substring(0, r + 1);
}
