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?

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!
}
