Question

我有一个简单的“谁是”游戏页面，我想用Greasemonkey制作一个简单的自动回答脚本。我该怎么做？

基于图片sid中的src：

<img src="whois_picture.php?yid=123456&sid=3084" />

应该点击匹配的链接......

如果sid=3084，请选择回答d。
如果sid=3023，请选择回答a。

关键目标页面HTML：

<div id="whois_guestion">
    <img src="whois_picture.php?yid=123456&sid=3084" />
</div>
<div id="game_options">
    <a href="#" class="game_option">Mickey Mouse</a>
    <input type="hidden" value="a" name="secenekharf" />

    <a href="#" class="game_option">Bugs Bunny</a>
    <input type="hidden" value="b" name="secenekharf" />

    <a href="#" class="game_option">Gofy</a>
    <input type="hidden" value="c" name="secenekharf" />

    <a href="#" class="game_option">Mario</a>
    <input type="hidden" value="d" name="secenekharf" />
</div>

Answer 1

创建sid s的对象并回答，如下：

var answerKey   = {
      3084: "d"
    , 3023: "a"
    //etc.
};

然后使用jQuery选择正确的答案链接。
最后，发送链接点击事件。

以下是完整脚本的外观：

// ==UserScript==
// @name     _Auto-answer script
// @include  http://thedudu.com/auto_select/*
// @require  http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
// @grant    GM_addStyle
// ==/UserScript==
/*- The @grant directive is needed to work around a design change introduced
    in GM 1.0.   It restores the sandbox.
*/

var answerKey   = {
      3084: "d"
    , 3023: "a"
    //etc.
};

setTimeout (clickAnswerIfAny, 222); //-- 222 milliseconds

function clickAnswerIfAny () {
    var questImg    = $("#whois_guestion img");
    var questSid    = questImg.attr ("src").replace (/^.+?\bsid=(\d+).*$/i, "$1");
    var answerVal   = answerKey[questSid];
    if (typeof answerVal != "undefined") {
        console.log ("Ans found...");
        //-- Find the <input> with the answer value.
        var answerInp   = $("#game_options input[value='" + answerVal + "']");
        if (answerInp.length) {
            //-- In this case, the link is the previous sibling element.
            var answerLink  = answerInp.prev ();
            console.log (answerInp, answerLink);
            //-- Click the link.
            console.log ("Clicking...");
            var clickEvent  = document.createEvent ('MouseEvents');
            clickEvent.initEvent ('click', true, true);
            answerLink[0].dispatchEvent (clickEvent);
        }
    }
}
