本文介绍了一个简单的JavaScript函数，用于验证表单中输入的电子邮件地址是否包含必要的 '@' 字符。如果缺少该字符，则会显示错误消息。

I am new to developing sites, I have created a form with a persons contact details.

In the email text field I would like to only allow email addresses with the character @, if the '@' character is not present, then an error message will be displayed.

Html code for email entry is:

Javascript to ensure that the field is entered is:

function checkShippingAndPaymentInfo()

{

with (window.document.frmCheckout) {

if (isEmpty(txtEmail, 'Please enter your email address')) {

return false;

} else {

return true;

}

The code above works but does not have the restriction I require. All I need is validation for the '@' character to be set in the text entry field. Please can someone help me with this.

Thank you in advance.
