Is there a way to capture the alert ok button click event? In jQuery?

推荐答案

alert（）函数是同步的，你无法验证点击的内容（它不会返回任何内容），所以调用后的代码将在关闭后执行（确定或关闭按钮）。警报不用于获取用户输入。这是一个警报，给用户一条消息。如果您需要检查用户想要的内容，则应使用confirm（）。请注意，函数名称告诉其目的，如alert。

The alert() function is synchronous and you can't verify what was clicked (it does not return nothing), so the code below the call will be executed after it is closed (ok or close button). The alert is not used to gain user input. It is an alert, a message to the user. If you need to check what the user want, you should use confirm(). Note that the function name tells its purpose like alert.

类似于：

// if the ok button is clicked, result will be true (boolean)
var result = confirm( "Do you want to do this?" );

if ( result ) {
    // the user clicked ok
} else {
    // the user clicked cancel or closed the confirm dialog.
}
