条件面板和单选按钮选择不起作用

Question

我正在尝试使用基于Radio按钮输入的条件面板，如下所示

radioButtons("Type","Review Type:",c("Type1","Type2","Type3"),inline=T)

条件面板语句如下，

conditionalPanel(condition = "input.Type == 'Type1'",wellPanel(
radioButtons("Question1", "do you know R shiny?"choices = c("Y","N","NA"),selected = "Y",inline=T)

conditionalPanel(condition = "input.Type == 'Type2'",wellPanel(
radioButtons("Question1", "do you know Python?"choices = c("Y","N","NA"),selected = "Y",inline=T)


conditionalPanel(condition = "input.Type == 'Type3'",wellPanel(
radioButtons("Question1", "do you know Java?"choices = c("Y","N","NA"),selected = "Y",inline=T)

如果您在条件面板中注意到radioButton id（＆＃34; Question1＆＃34;）在所有条件面板中都是相同的，条件本身对我有效，但我为所有人设置了selected = "Y"由于某种原因无法正常工作的无线电按钮（仅适用于第三个条件面板）

Answer 1

它的行为方式是因为您的所有radioButtons都具有相同的ui <- fluidPage( radioButtons(inputId = "Type", label = "Review Type:", choices = c("Type1", "Type2", "Type3"), inline = T), conditionalPanel(condition = "input.Type == 'Type1'", wellPanel( radioButtons(inputId = "Question1", label = "do you know R shiny?", choices = c("Y", "N", "NA"), selected = "Y", inline = T) ) ), conditionalPanel(condition = "input.Type == 'Type2'", wellPanel( radioButtons(inputId = "Question1", label = "do you know Python?", choices = c("Y", "N", "NA"), selected = "Y", inline = T) ) ), conditionalPanel(condition = "input.Type == 'Type3'", wellPanel( radioButtons(inputId = "Question1", label = "do you know Java?", choices = c("Y", "N", "NA"), selected = "Y", inline = T) ) ) ) ，因此它们只被视为一个UI元素。为您的content提供一个唯一名称，这样可以正常使用：

angular.module('plunker', [])
    .controller('MainCtrl', function ($scope) {

    })
    .directive('myDom', function () {
        return {
            restrict: 'EA',
            replace: true,
            transclude: true,
            scope: true,
            template: '<div>{{myContent}}: {{oldContent}}</div>',
            controller: function () {
            },
            link: {
                pre: function (scope, elem, attr, ctrl, transclude) {
                    transclude(function (clone) {
                        scope.myContent = attr["attri"];
                        scope.oldContent = clone.text();
                    });
                }
            }
        };
    });
