在提交表单之前，我需要一个函数来检查@和.符号。

负责检查值是否被插入的函数：

// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {

    // validate fields
    if(!name_txt.length) {
        status_txt.text = "Please enter your name";
    } else if (!email_txt.length) {
        status_txt.text = "Please enter your e-mail address";
    } else if (!phone_txt.length) {
        status_txt.text = "Please enter your phone number";
    } else {

        // All is good, send the data now to PHP

        // ready the variables in our form for sending
        variables.userName = name_txt.text;
        variables.userEmail = email_txt.text;       
        variables.userPhone = phone_txt.text;
        variables.userShop = shopList.value;

        // Send the data to PHP now
        varLoader.load(varSend);

    } // close else condition for error handling

} // close validate and send function

我尝试创建一个单独的函数来检查电子邮件符号：

// Checking e-mail
function checkEmail():Boolean {

    var reEmail:String = email_txt.text;
    var emailOk:Boolean = false;
    var checkArray1:Array = reEmail.split("@");
    if (checkArray1.length >1) {

        var checkArray2:Array = checkArray1[1].split(".");
        if (checkArray2.length >1) {

            emailOk = true;
        }
    }
    return emailOk;
}

但这不起作用。您将如何实现这一目标？

更新：我试过在函数内部运行ValidateAndSend函数。但是现在如果电子邮件地址错误，它不会发送消息，但仍会显示成功提交消息。 

// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {

// validate fields
if(!name_txt.length) {
    status_txt.text = "Please enter your name";
} else if (!email_txt.length) {
    status_txt.text = "Please enter your e-mail";

    // Checking e-mail
    function checkEmail():Boolean {

    var reEmail:String = email_txt.text;
    var emailOk:Boolean = false;
    var checkArray1:Array = reEmail.split("@");
    if (checkArray1.length >1) {

        status_txt.text = "Please check your e-mail address";

        var checkArray2:Array = checkArray1[1].split(".");
        if (checkArray2.length >1) {

            emailOk = true;
        }
    }
    return emailOk;
    }

} else if (!phone_txt.length) {
    status_txt.text = "Please enter your phone number";
} else {

    // All is good, send the data now to PHP

    // ready the variables in our form for sending
    variables.userName = name_txt.text;
    variables.userEmail = email_txt.text;       
    variables.userPhone = phone_txt.text;
    variables.userShop = shopList.value;

    // Send the data to PHP now
    varLoader.load(varSend);

} // close else condition for error handling

} // close validate and send function

您应该为此使用正则表达式。

不需要您的 checkEmail() 函数

// function ValidateAndSend
function ValidateAndSend (event:MouseEvent):void {
    var emailCheckRegExp:RegExp = /^[\w.-]+@\w[\w.-]+\.[\w.-]*[a-z][a-z]$/i;
    // validate fields
    if(name_txt.length == 0) {
        status_txt.text = "Please enter your name";
    } 
    else if (email_txt.length == 0) {
        status_txt.text = "Please enter your e-mail address";
    } 
    else if (phone_txt.length == 0) {
        status_txt.text = "Please enter your phone number";
    }
    else if(emailCheckRegExp.exec(email_txt.text) == null)
    {
        status_txt.text = "Entered e-mail is not valid";
    }
    else {

        // All is good, send the data now to PHP

        // ready the variables in our form for sending
        variables.userName = name_txt.text;
        variables.userEmail = email_txt.text;       
        variables.userPhone = phone_txt.text;
        variables.userShop = shopList.value;

        // Send the data to PHP now
        varLoader.load(varSend);

    } // close else condition for error handling

} // close validate and send function
