所以我想为一个项目制作一个页面，当你点击窗口上的“确定”确认时，它会将你带到一个登录论坛（即有效）。但是，如果你点击取消，登录论坛不会加载，它会把你带到别的地方。我将如何做到这一点？我是Javascript新手，所以我很抱歉不清楚我的问题。这里是我的代码：取消激活上一个命令
// variable information
var person = {
name: " Alex, ",
age: " 27 years old, ",
height: "183cm, ",
born: " born January 12th 1996, ",
weight: " 130 Lb "
};
window.alert("Information. Click ok to continue");
//confirm box, determines if forum loads or not... or thats the plan.
{
if (confirm("All information in this is to remain private. Do not share any information given. Please accept these conditions.") == true) {
alert("Now loading file information. Please wait a moment...");
//number of attempts
var attempt = 3;
// executes on click below
function validate() {
var username = document.getElementById("username").value;
var password = document.getElementById("password").value;
if (username == "Correct" && password == "1141") {
alert("Login successfully");
var x = person.age;
var y = person.name;
var z = person.born;
var a = person.height;
var b = person.weight;
document.write(y);
document.write(x);
document.write(z);
document.write(a);
document.write(b);
return false;
} else {
// chances available.
alert("incorrect login. You have " + attempt + " attempt;");
// Disables after 2 attempts
if (attempt == 0) {
document.getElementById("username").disabled = true;
document.getElementById("password").disabled = true;
document.getElementById("submit").disabled = true;
return false;
}
}
}
}
// if false
else
alert("Could not load. Error 707.");

在你的'如果（确认（））'测试，你想用'window.location'更改URL。这里是一个例子https://codepen.io/mcoker/pen/oWGYwz –
