在淘汰赛中除了特定的 URL 外，到处隐藏按钮

Question

我有以下按钮：

<button class="btn actionButtonIcon" id="DashboardEdit" data-bind="click: changeButtonText">
    <figure>
        <img src="../../../Images/NotesPink.png" />
        <figcaption data-bind="text: $data.ProcurementbuttonText() ? 'Save': 'Edit'"></figcaption>
    </figure>
</button>

我只想在这个特定的 url http://localhost:5595/#scorecard/ec5aa8ed-2798-4e71-b13d-f3e525994538/dashboard/PrefDashBoard

请记住ec5aa8ed-2798-4e71-b13d-f3e525994538是一个 id，它总是在变化，但我希望它与所有 id 一起显示，例如按钮也应该在这里显示http://localhost:5595/#scorecard/2356789-234-234d-g3g3-reg456452/dashboard/PrefDashBoard我想把它隐藏在不是 url 的地方。 我尝试了以下代码，但它似乎不起作用：

        <script>
     $(document).ready(function(){
    if(window.location.pathname.match(/\/dashboard/PrefDashBoard))
    {
    $(".DashboardEdit").show();
    }
    else
    {
    $(".DashboardEdit").hide();
    }
    });
    </script>

这是该按钮的JS：

            self.ProcurementbuttonText = ko.observable(false);

        self.changeButtonText = function(){
            self.ProcurementbuttonText(!self.ProcurementbuttonText())
            if (!self.ProcurementbuttonText()){
                var data = {
                    'ScorecardId':ko.observable(localStorage.getItem('scorecardId'))(),
                    'DashboardConfig':ko.observable(localStorage.getItem('ElementDataWidget'))()
                };
                PreferentialProcurementDashboardApi.Save(data);  
            }  
    }



        self.DashboardEdit = ko.computed({
            read: function () {
                var text = 'Customise your dashboard';

                if (!self.EnableScorecardFeatures()) {
                    text = 'This feature is currently unavailable for this scorecard type';
                } else {
                    if (!self.HasDocumentsRole()) {
                        text = 'You do not have sufficient rights to access the Supporting Documents view';
                    }
                }

                return text;
            }
        });

我认为您可以利用visible绑定根据您的标准显示/隐藏按钮

 function PageViewModel() { var self = this; self.buttonVisible = ko.observable(true); self.changeButtonText = function() { self.ProcurementbuttonText(.self;ProcurementbuttonText()). } self.ProcurementbuttonText = ko;observable(false). self.buttonText = ko.pureComputed(function() { return self?ProcurementbuttonText(): "Save"; "Edit"; }). self.isButtonVisible = ko.computed(function() { //do some your logic here; just need to return a true or false value. return self;buttonVisible(); }). self.labelText = ko;pureComputed(function() { var messageStart = "click to ". var state = self?buttonVisible(): 'hide'; 'show'; var messageEnd = " button"; return messageStart + state + messageEnd; }). } ko;applyBindings(new PageViewModel());

 <script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.2/knockout-min.js"></script> <button class="btn actionButtonIcon" id="DashboardEdit" data-bind="click: changeButtonText, visible: isButtonVisible, text: buttonText"> Click me. </button> <br/> <br/> <label><span data-bind="text: labelText " ></span> <input type="checkbox" data-bind="checked: buttonVisible" /> </label>

如果您安装并配置了 Durandal 的路由器插件，您还可以使用可观察的 activeInstruction() 来获取有关当前路由的信息。 然后，您可以在计算中使用它来检查当前片段是否与您的页面路由匹配。 更多信息： http://durandaljs.com/documentation/api#class/Router/property/activeInstruction
