回答by Nick Shaw
The code after the alert()call won't be executed until the user clicks ok to the alert, so just put the code you need afterthe alert()call.
alert()调用后的代码不会执行，直到用户单击“确定”以提醒警报，因此只需在调用后放置您需要的代码即可alert()。
If you want a nicer floating dialog than the default javascript confirm()popup, see jQuery UI: floating window
如果您想要一个比默认 javascriptconfirm()弹出窗口更好的浮动对话框，请参阅jQuery UI：浮动窗口

var r = confirm("Press a button!");
if (r == true) {
alert("You pressed OK!");
}
else {
alert("You pressed Cancel!");
}
