使用"accept“和"deny”创建确认框

Question

当用户访问我的网站时，我如何创建一个包含接受和拒绝两个选项的对话框？我需要接受按钮，以继续我的网站，并拒绝按钮，把访问者带到他们的最后一个网页。

到目前为止，我有：

var confirmation = confirm('Do you want to continue on this website?');
if (!confirmation){
    // Redirect the user to his last webpage:
    history.go(-1);
}

如果您想要使用jquery，则需要在页面中包含Jquery并定义以下函数

function confirmation(question) {
var defer = $.Deferred();
$('<div></div>')
    .html(question)
    .dialog({
        autoOpen: true,
        modal: true,
        title: 'Confirmation',
        buttons: {
            "Accept": function () {
                defer.resolve("true");//this text 'true' can be anything. But for this usage, it should be true or false.
                $(this).dialog("close");
            },
            "Deny": function () {
                defer.resolve("false");//this text 'false' can be anything. But for this usage, it should be true or false.
                $(this).dialog("close");
            }
        }
    });
return defer.promise();
};

然后按照下面的方式使用它

 confirmation('Do you want to continue on this website?').then(function (answer) {

                if (answer == "false") {
                    // your logic

                }
                else if (answer == "true") {
                    // your logic
                }
            });

如果你想使用jQuery UI，你可以这样做：

HTML：

<div id="ask">
    <h1> Some title </h1>
    <p> Some info </p>
</div>  

JS：

  $(function() {
    $( "#ask" ).dialog({
      resizable: false,
      modal: true,
      buttons: {
        "Allow": function() {
            alert("You have been allowed");
            // more allow code here
        },
        "Deny": function() {
            alert("You have been denied");
            history.go(-1);
            // more deny code here
        }
      }
    });
  }); 

FIDDLE

你必须在你的页面中包含jQuery UI。
