如何创建带有“确定"和“取消"选项的对话框
我将制作一个按钮来执行操作并将数据保存到数据库中.
I am going to make a button to take an action and save the data into a database.
一旦用户单击按钮，我希望 JavaScript 警报提供是"和取消"选项.如果用户选择是"，则将数据插入数据库，否则不执行任何操作.
Once the user clicks on the button, I want a JavaScript alert to offer "yes" and "cancel" options. If the user selects "yes", the data will be inserted into the database, otherwise no action will be taken.
如何显示这样的对话框?
How do I display such a dialog?
推荐答案
您可能正在寻找 confirm()，它会显示一个提示并返回 true 或 false用户决定:
You’re probably looking for confirm(), which displays a prompt and returns true or false based on what the user decided:
if (confirm('Are you sure you want to save this thing into the database?')) {
// Save it!
console.log('Thing was saved to the database.');
} else {
// Do nothing!
console.log('Thing was not saved to the database.');
