javascript - 如何使用“是”和“否”选项创建对话框？(How to create a dialog with “yes” and “no” options?)

Question

I am going to make a button to take an action and save the data into a database.(我将创建一个按钮来执行操作并将数据保存到数据库中。)

Once the user clicks on the button, I want a JavaScript alert to offer “yes” and “cancel” options.(一旦用户点击按钮，我想要一个JavaScript提醒，提供“是”和“取消”选项。) If the user selects “yes”, the data will be inserted into the database, otherwise no action will be taken.(如果用户选择“是”，则数据将被插入数据库，否则将不执行任何操作。) How do I display such a dialog?(如何显示这样的对话框？)   ask by crchin translate from so

You're probably looking for confirm() , which displays a prompt and returns true or false based on what the user decided:(您可能正在寻找confirm() ，它会显示提示并根据用户决定的内容返回true或false ：)

if (confirm('Are you sure you want to save this thing into the database?')) { // Save it! } else { // Do nothing! }
