我试图使用"with"绑定在数组中显示后代元素.但它只显示"练习"中的最后一项,我希望看到所有这些项目.怎么可能解决这个问题？之后,如何使阵列中的每个项目都可编辑？

我的ViewModel:

    function AppViewModel() {   
    var self = this;

    self.workouts = ko.observableArray([
        {name: "Workout1", exercises:{
            name: "Exercise1.1",
            name: "Exercise1.2",
            name: "Exercise1.3"
        }},
        {name: "Workout2", exercises:{
            name: "Exercise2.1",
            name: "Exercise2.2",
            name: "Exercise2.3"
        }},
        {name: "Workout3", exercises:{
            name: "Exercise3.1",
            name: "Exercise3.2",
            name: "Exercise3.3"
        }},        
        {name: "Workout4", exercises:{
            name: "Exercise3.1",
            name: "Exercise3.2",
            name: "Exercise3.3"
        }},        

]);

    self.removeWorkout = function() {
        self.workouts.remove(this);
    };
}

ko.applyBindings(new AppViewModel());

风景:

<div class="content">
    <ul data-bind="foreach: workouts">
        <li>
        <span data-bind="text: name"> </span>
         <a href="#" data-bind="click: $parent.removeWorkout">Remove</a>
         <ul data-bind="with: exercises"> …
