javascript - JQuery:从提交的模式对话框中获取值

Question

我刚开始使用 JQuery，我正在经典的 asp 页面中编辑模态弹出窗口示例。我已经让表单开始工作，并添加了一个提交行，但在提交之后，我尝试使用 request.form("email") 通过 asp 获取提交的值，但结果是空白。

这是我提交方式、读取值的方式或其他方面的问题吗？我需要做什么才能提交表单并获取值？

代码如下:

我用这个调用对话框:

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

对话框形式:

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

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

                    // From jquery.validate.js (by joern), contributed by Scott Gonzalez: http://projects.scottsplayground.com/email_address_validation/
                    bValid = bValid && checkRegexp(email, /^((([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z]|\d|[!#\$%&'\*\+\-\/=\?\^_`{\|}~]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*)|((\x22)((((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(([\x01-\x08\x0b\x0c\x0e-\x1f\x7f]|\x21|[\x23-\x5b]|[\x5d-\x7e]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(\\([\x01-\x09\x0b\x0c\x0d-\x7f]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]))))*(((\x20|\x09)*(\x0d\x0a))?(\x20|\x09)+)?(\x22)))@((([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|\d|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.)+(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])|(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])([a-z]|\d|-|\.|_|~|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])*([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])))\.?$/i, "Please enter a valid email address.");

                    if (bValid) {
                        $("#users tbody").append("<tr>" +
                                "<td>" + email.val() + "</td>" +
                            "</tr>");
                        $(this).dialog("close");
                        $("form[name='modalPopup']").submit()

                    }

                },
                Cancel: function () {
                    $(this).dialog("close");
                }
            },
            close: function () {
                allFields.val("").removeClass("ui-state-error");
            }
        });

        $("#send-password")

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


    });
</script>

表单已提交到 SendLogin.asp，我尝试通过以下方式接收值:

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

但是当我之后尝试打印时，tempEmail 显示为空白。我需要做什么来获取提交的表单值？

感谢任何帮助!

尝试将您的提交更改为:

document.modalPopup.submit();
