Question

我的应用服务器上有一个.Net webservice，它返回格式化为JSONP的数据。我在该服务器上有一个HTML测试客户端，使用IE，Firefox和＆amp;铬。如果我将相同的HTML复制到我的工作站或部署到我的网络服务器，它适用于Firefox＆amp; Chrome但在IE中我遇到两个javascript错误。

我有点不知道如何解决这个问题。

这是我的javascript。它实际上不是导致错误的JSONP，而是对jqModal ev.preventDefault（）; 的调用。我现在正试图通过这个来看看为什么它会在IE上用外部引用进行轰炸。

<script type="text/javascript">
    $(document).ready(function() {
        $("#createUser").live("click", function(ev) {
            var invalidEmailAddressMessage = "That isn't a valid email address.";
            var userSuccessfullyAddedMessage = "Congrats! You've been added to the iStage mailing list.";
            var userAlreadyExistsMessage = "Looks like you're already on our mailing list!";
            var genericErrorMessage = "Something fishy happened. I don’t know what to tell you.";

            // check for a valid email address
            var regEmail = /^([A-Za-z0-9_\-\.])+\@([A-Za-z0-9_\-\.])+\.([A-Za-z]{2,4})$/;
            if(regEmail.test($("#email").val()) == false) {
                // invalid email address. Show error and let user retry.
                ev.preventDefault();
                $('#lyrisReturnStatus').jqmShow().oneTime(3500, "soon", function() {
                    $('#lyrisReturnStatus').jqmHide();
        });
        $("#output").html(invalidEmailAddressMessage);
        $("#email").select();
        return;
            }

            // Call the proxy to add the user
            var service = new WS("http://apps.ce.org/WebServices/LyrisProxy/Services/Lyris/JSONP/Lyris.asmx", WSDataType.jsonp);
            service.call("AddUser", { lyrisInstance:$("#lyrisInstance").val(), email:$("#email").val(), fullName:$("#fullName").val(), lyrisList:$("#lyrisList").val() }, function(AddUser) {
                var lyrisReturn = JSON.parse(AddUser);
                var goBack;
                var timeout;

                // See if the JSON returned is an error message and handle.
                if(typeof(lyrisReturn.ErrorMessage) !== 'undefined' && lyrisReturn.ErrorMessage != null) {
                    var pos=lyrisReturn.ErrorMessage.indexOf("member already exists");
                    if (pos>=0)
                    {
                        // Member already exists.
                        $("#output").html(userAlreadyExistsMessage);
                        goBack = true;
                    } else {
                        // Generic error.
                        $("#output").html(genericErrorMessage);
                        goBack = false;
                    }
                    timeout = 3500;
                }
                // See if the JSON returned the expected MemberID
                if(typeof(lyrisReturn.MemberID) !== 'undefined' && lyrisReturn.MemberID != null) {
                    $("#output").html(userSuccessfullyAddedMessage);
                    goBack = true;
                    timeout = 2000;
                }

                //Show the modal display with the appropriate messaging and redirect.
                ev.preventDefault();
                $('#lyrisReturnStatus').jqmShow().oneTime(timeout, "soon", function() {
                    $('#lyrisReturnStatus').jqmHide();
                    if(goBack) {
             history.go(-1);
         }
    });

            });
        });
        $('#lyrisReturnStatus').
          jqm({ overlay: 50, modal: true, trigger: false });
    });
</script>
