Question

我刚开始使用JQuery，我正在编辑经典asp页面中的模态弹出示例。我已经让表单工作了，并添加了一个提交行，但在提交之后我尝试使用request.form（“email”）获取提交的值，但它是空白的。

这是我提交的方式，我如何阅读价值观或其他内容的问题？提交表单并获取值需要做什么？

以下是代码：

我用这个来调用对话框：

<strong>Forgot your login?:</strong> <a href="#" id="send-password">click here</a></p>

对话框表单：

<div id="dialog-form" title="Send My Login">
        Enter the email address associated with your account. Your password will be sent to you.
        <br />
        <strong>If you do not have an email address</strong>, or do not 
        remember it, please contact your Human Resources department to have your login 
        provided to you.

        <p class="validateTips">

         </p>

        <form action="SendLogin.asp" method="Post" name="modalPopup">
        <fieldset>

            <label for="email">Email</label>
            <input type="text" name="email" id="email" value="" class="text ui-widget-content ui-corner-all" />

        </fieldset>
        </form>
    </div>

对话框代码：

<script type="text/javascript">

    $(function () {

        //Modal pop-up form
        // a workaround for a flaw in the demo system (http://dev.jqueryui.com/ticket/4375), ignore!
        $("#dialog:ui-dialog").dialog("destroy");

        var email = $("#email"),
                allFields = $([]).add(email);
                tips = $(".validateTips");

        function updateTips(t) {
            tips
                    .text(t)
                    .addClass("ui-state-highlight");
            setTimeout(function () {
                tips.removeClass("ui-state-highlight", 1500);
            }, 500);
        }

        function checkLength(o, n, min, max) {
            if (o.val().length > max || o.val().length < min) {
                o.addClass("ui-state-error");
                updateTips("Length of " + n + " must be between " +
                        min + " and " + max + ".");
                return false;
            } else {
                return true;
            }
        }

        function checkRegexp(o, regexp, n) {
            if (!(regexp.test(o.val()))) {
                o.addClass("ui-state-error");
                updateTips(n);
                return false;
            } else {
                return true;
            }
        }

        $("#dialog-form").dialog({
            autoOpen: false,
            height: 350,
            width: 350,

            buttons: {
                "Send Login": function () {
                    var bValid = true;
                    allFields.removeClass("ui-state-error");

                    bValid = bValid && checkLength(email, "email", 5, 80);

                        $("#users tbody").append("<tr>" +

        $("#send-password")

                .click(function () {
                    $("#dialog-form").dialog("open");
                });


    });
</script>

表单提交给SendLogin.asp，我尝试使用以下方法接收值：

<%tempEmail=request.form("email")%>

但是当我尝试打印后，tempEmail会出现空白。我需要做什么才能获得提交的表单值？

感谢任何帮助！

尝试将提交更改为：

document.modalPopup.submit();

JQuery：从提交的模式对话框中获取值
