如何获取它，以便当用户点击回车键时，它会激活与活动标题相关联的按钮？

首先，我们可以捕获输入元素的按键事件。如果按键是输入＆＃39;密钥，然后我们会将click()发送给“活跃的＆＃39;按钮。我们将其存储在全局变量window.actionButton中。

$(':input').keyup(function (event) {
    if (event.keyCode == 13) {
        window.actionButton.click();
    }
});

如果我们假设每个面板都包含class='action'的单个按钮，那么我们就可以跟踪“活跃”按钮。按钮。

window.actionButton = ui.newPanel.find(".action");

每当选择标题（+面板）时，activate事件都会触发。在页面加载期间，我们将函数绑定到该操作，并让它更新window.actionButton。

activate: function (event, ui) {
    window.actionButton = ui.newPanel.find(".action");
},

如果我们移动焦点以突出显示预期的操作，工作流程会得到改善。理想情况下，焦点应该转到下一个输入，无论是什么，但在这个简单的手风琴中它足以移动到适当的按钮：

window.actionButton.focus();

不幸的是，在Google Apps脚本HtmlService中运行时，我们可以定位程序化按钮点击但无法控制焦点：Cannot simply force focus on text input in stand-alone Google App using HtmlService?您会发现jsFiddle的操作方式与HtmlService中的操作方式不同。 / p>
