Adaptive Card 日期容器可见性切换问题解决方法

你遇到的问题是Adaptive Cards可见性逻辑的表达式写法不符合规范，以下是修正方案及错误原因说明：

错误原因分析

错误引用triggerOutputs：卡片内部控件的交互逻辑无需使用triggerOutputs，直接通过控件ID（feature_choice）引用其值即可。
错误使用conditions属性：Adaptive Cards中不存在conditions这个控制可见性的属性，容器类元素的可见性控制应使用when属性。
contains表达式不适用：此处需要精确匹配选项值，contains是包含匹配逻辑，不符合需求。
when属性表达式格式错误：你当前的${feature_choice.value == 'Date Wise Leave'}不是Adaptive Expression Language（AEL）的正确写法。

正确代码实现

将date_selection_container的when属性修改为AEL的精确匹配表达式即可：

{
    "type": "Input.ChoiceSet",
    "id": "feature_choice",
    "label": "Which type of leave information you needed?",
    "placeholder": "Please Select the feature type",
    "value": "Monthly Leave",
    "choices": [
        {
            "title": "Monthly Leave",
            "value": "Monthly Leave"
        },
        {
            "title": "Date Wise Leave",
            "value": "Date Wise Leave"
        },
        {
            "title": "Recent 5 Leave",
            "value": "Recent 5 Leave"
        }
    ],
    "isRequired": true,
    "wrap": true,
    "separator": true
},
{
    "type": "Container",
    "id": "date_selection_container",
    "padding": "None",
    "when": "=equals(feature_choice.value, 'Date Wise Leave')",
    "items": [
        {
            "type": "Input.Date",
            "label": "From",
            "id": "start_date_input"
        },
        {
            "type": "Input.Date",
            "label": "To",
            "id": "end_date_input",
            "value": "2023-04-27"
        }
    ]
}
