This is a simple function that will help validate an email address. Normally it is used with the onBlur portion of an input...
|
function emailvalidate(inEmail1) {
if (inEmail1.value.length > ) {
if ((inEmail1.value.lastIndexOf(".") < inEmail1.value.indexOf("@")+3 || inEmail1.value.lastIndexOf(".") > inEmail1.value.length-3 || inEmail1.value.indexOf("@") < 1) || inEmail1.value.indexOf("@") != inEmail1.value.lastIndexOf("@")) {
alert("Email Validation Failed");
}
}
}
// to call this... put onBlur="emailvalidate(this);" into the email field
// of your input form...
// Example:
// <input type="text" name="email" onBlur="emailvalidate(this);">
