knockout.js and “with” binding in IE8 corrupts page

问题

I am using the "with" binding in knockout.js, and it works fine below in say Chrome and IE9, but when I move to IE8 the form doesnt submit anymore. I remove the "with" it does just fine. In Visual Studio the "with" keyword is blue telling me it's a reserved word. Is there anyway around this for IE8?

<form class="box clearfix" action="@Request.RawUrl" data-bind="with: members.events, form: { id: @Model.Event.Id }">


ko.bindingHandlers.form = {
    init: function (element, valueAccessor) {

        var value = ko.utils.unwrapObservable(valueAccessor());

        $(element).find('button[type=submit]:last').click(function () {

            if (typeof (value.submit) == 'function') {
                value.submit();
            } else {
                app.call({
                    type: 'POST',
                    data: $(element).serializeObject(),
                    url: $(element).attr('action'),
                    success: function (result) {

                        if (value.replace) {
                            app.updateContainerWithHtml(result);
                        } else {
                            if (value && value.id == 0 && typeof(result) == 'string') {
                                window.location.hash = result;
                            } else {
                                if (typeof (value.callback) == 'function') {
                                    value.callback(result);
                                }
                            }

                            if (value.hideSuccess == undefined && !value.hideSuccess) {
                                if (result.Url) {
                                    app.showSuccess(result.Message, function() {
                                        window.location.hash = result.Url;
                                    });
                                } else {
                                    app.showSuccess();
                                }
                            }
                        }
                    }
                });
            }

            return false;
        });

    }
};

I had the same issue found here

and I just had to refer to my objects with long data-binds like members.events.title instead of title.

My section of code was small as it was just for an attachment section so it wasnt too annoying. You can try escaping the with, like data-bind="'with': , like you do with the ko comments for if's to make them work with IE but I am doubtful that would work.
