Question

我试图在IE11中使用JQuery进行Ajax发布。我已经修改了ie-9的兼容性元标记，但它仍然不起作用，不会发送帖子。相反，它会从jquery引发错误{exception} Unable to get property 'settings' of undefined or null reference。

jquery的

$('#EmailForm').validate({
            invalidHandler: function(event, validator) {
                var errors = validator.numberOfInvalids();
                if (errors) {
                    var message = errors == 1
                      ? '1 email field has a missing or invalid email address. It has been highlighted, please correct this or remove the field.'
                      : errors + ' email fields have  missing or invalid email addresses. It has been highlighted, please correct this or remove the fields.';
                    $("div.error span").html(message);
                    $("div.error").show();
                } else {
                    $("div.error").hide();
                }
            },
            submitHandler: function (form) {
                $(form).ajaxSubmit(function () {
                    history.go(-1);
                });
            }
        });

        $('body').on('click', '.remove_field', function () {
            $(this).closest('p').remove();
        });
        $('.add_email_button').closest('p').click(function () {
            var html = '<p><input type="email" class="email" form="EmailForm" required name="EmailAddresses" /><span class="btn_orange"><a href="#" class="remove_field">x</a></span></p>';
            $(html).insertBefore($(this));
        });
        $('#SendEmail_Button').closest('span').click(function (e) {
            e.preventDefault();
            $('#EmailForm').submit();
           @* if ($('#EmailForm').valid()) {
                $.post('@Url.Action("PostEmail")', $('#EmailForm').serialize()).done(function() {
                    history.go(-1);
                });
            }*@
        });

  <customHeaders>
    <clear/>
    <add name="X-UA-Compatible" value="IE=IE9"/>
  </customHeaders>

Answer 1

你需要做

$("#EmailForm").validate({
    // options
});

，然后才能使用$("#EmailForm").valid()。

对于历史运动，请在AJAX完成后执行：

submitHandler: function(form) {
    $(form).ajaxSubmit(function() {
        history.go(-1);
    });
}
