knockout.js和“with” IE8中的绑定会破坏页面 [英] knockout.js and "with" binding in IE8 corrupts page

问题描述

我在knockout.js中使用with绑定，并且在Chrome和IE9中它可以正常工作，但是当我移动到IE8时，表单不再提交了。我删除了有它做得很好。在Visual Studio中，with关键字为蓝色，告诉我这是一个保留字。 IE8还有吗？

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;
        });

    }
};

推荐答案

我遇到了同样的问题在这里找到

我只需要使用长数据绑定来引用我的对象，例如 members.events.title 而不是 title 。

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

我的代码部分很小，因为它只是一个附件部分所以它并不太烦人。您可以尝试转义with，例如 data-bind ='with'：，就像你使用ko评论if if使它们与IE一起使用但我怀疑那会有效。

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.
