我如何使用Greasemonkey自动选择特定的单选按钮？ [英] How can I automatically select specific radio buttons with Greasemonkey?
问题描述
我想用Greasemonkey自动回答问题。我有问题和答案，但如何选择它们？
以下是HTML：
< div class =vito_form_q >
< div class =vito_form_title_min_no>
< span id =ContentPlaceHolder1_lblquestionNo> 8< / span>
< / div>
< div class =vito_form_title_min>
< span id =ContentPlaceHolder1_lblquestion>哪一项运动不是在玩球？< / span>
< / div>
< div class =clearfloat>< / div>
< div class =meter orange nostripes>< span style =width：100％>< / span>< / div>
< div class =quest>
< table id =rbAnswerclass =q1>
< tr>< td>
< input id =rbAnswer_0type =radioname =ctl00 $ ContentPlaceHolder1 $ rbAnswervalue =157/>< label for =rbAnswer_0>手球< / label>
< / td>< / tr>
< tr>< td>
< input id =rbAnswer_1type =radioname =ctl00 $ ContentPlaceHolder1 $ rbAnswervalue =158/>< label for =rbAnswer_1> Basketball< / label>
< / td>< / tr>
< tr>< td>
< input id =rbAnswer_2type =radioname =ctl00 $ ContentPlaceHolder1 $ rbAnswervalue =159/>< label for =rbAnswer_2> Football< / label>
< / td>< / tr>
< tr>< td>
< input id =rbAnswer_3type =radioname =ctl00 $ ContentPlaceHolder1 $ rbAnswervalue =160/>< label for =rbAnswer_3> Fencing< / label>
< / td>< / tr>
例如，对于这个问题：
< span id =ContentPlaceHolder1_lblquestion>哪一项运动不是在玩球？<跨度>
选择答案：
< TD>
< input id =rbAnswer_3type =radioname =ctl00 $ ContentPlaceHolder1 $ rbAnswervalue =160/>
< label for =rbAnswer_3>隔离栏< / label>
我如何使用Greasemonkey做到这一点？
制作一系列的问题和答案，如下所示：
var answerKey = [
{q：sport is not playing with the ball，a：击剑}
，{q：Best SciFi franchise，a：Star Trek }
，{q：最坏的怪物，a：Bun-Bun}
，{q：此列表中最有毒的化学物质，a：露水}
//等等
];
然后添加这个请转至Greasemonkey脚本的元数据块：
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
I want to automatically answer questions with Greasemonkey. I have the questions and answers, but how can select them? Here's the HTML: For example, for this question: Select the answer: How can I do this with Greasemonkey? Make an array of questions and answers, like so: Then add this line to the Metadata Block of your Greasemonkey script: (See a demo of the underlying code at jsFiddle.)
这篇关于我如何使用Greasemonkey自动选择特定的单选按钮？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
然后，使用
var answerKey = [
{q：sport is not playing with the ball，a：Fencing}
，{q：Best SciFi特许经营，a：星际迷航}
，{q：最坏的怪物，a：Bun-Bun}
，{q：此列表中毒性最大的化学品， a：山露}
//等
];
// ---循环浏览页面上的问题并尽可能回答。
var questionTxt = $（div div.vito_form_title_min span [id $ ='question']）;
questionTxt.each（function（）{
var bFoundAnswer = false;
var answerTxt = getAnswer（this.textContent）;
if（answerTxt）{
// ---我们有答案文本，现在找到匹配的单选按钮并选择它
var ansForThisQ = $（this）.parent（）。nextAll（div.quest）。find label）;
ansForThisQ.each（function（）{
var zRegExp = new RegExp（answerTxt，'i'）;
if（zRegExp.test（this。 textContent））{
bFoundAnswer = true;
var label = $（this）;
var radioButt = $（＃+ label.prop（for））;
radioButt.prop（checked，checked）;
label.css（background，lime）;
返回false; //结束循环
}
}）;
}
else {
alert（我不知道如何回答：'+ this.textCont ent +'）;
$（this）.css（background，pink）;
}
if（answerTxt&！bFoundAnswer）{
alert（该页面没有针对该问题的指定答案：'+ this.textContent +'） ;
$（this）.css（background，pink）;
}
}）;
function getAnswer（questionText）{
for（var J = answerKey.length - 1; J> = 0; --J）{
var zRegExp = new RegExp answerKey [J] .q，'i'）;
if（zRegExp.test（questionText））
return answerKey [J] .a;
}
返回null;
}
<div class="vito_form_q">
<div class="vito_form_title_min_no">
<span id="ContentPlaceHolder1_lblquestionNo">8</span>
</div>
<div class="vito_form_title_min">
<span id="ContentPlaceHolder1_lblquestion">Which sport is not playing with the ball?</span>
</div>
<div class="clearfloat"></div>
<div class="meter orange nostripes"><span style="width: 100%"></span></div>
<div class="quest">
<table id="rbAnswer" class="q1">
<tr><td>
<input id="rbAnswer_0" type="radio" name="ctl00$ContentPlaceHolder1$rbAnswer" value="157"/><label for="rbAnswer_0">Handball</label>
</td></tr>
<tr><td>
<input id="rbAnswer_1" type="radio" name="ctl00$ContentPlaceHolder1$rbAnswer" value="158"/><label for="rbAnswer_1">Basketball</label>

<tr><td>

var answerKey = [
{ q: "sport is not playing with the ball", a: "Fencing" }
, { q: "Best SciFi franchise", a: "Star Trek" }
, { q: "Most badass monster", a: "Bun-Bun" }
, { q: "Most toxic chemical in this list", a: "Mountain Dew" }
// etc.
];
// @require http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js
Then, using the awesome power of jQuery, your script can check the right radio buttons with the following code:var answerKey = [
{ q: "sport is not playing with the ball", a: "Fencing" }
, { q: "Best SciFi franchise", a: "Star Trek" }
, { q: "Most badass monster", a: "Bun-Bun" }
, { q: "Most toxic chemical in this list", a: "Mountain Dew" }
// etc.
];
//--- Loop through the question(s) on the page and answer then if possible.
var questionTxt = $("div div.vito_form_title_min span[id$='question']");
questionTxt.each ( function () {
var bFoundAnswer = false;
var answerTxt = getAnswer (this.textContent);
if (answerTxt) {
//--- We have the answer text, now find the matching radio button and select it.
var ansForThisQ = $(this).parent (). nextAll ("div.quest").find ("label");
ansForThisQ.each ( function () {
var zRegExp = new RegExp (answerTxt, 'i');
if (zRegExp.test (this.textContent) ) {
bFoundAnswer = true;
var label = $(this);
var radioButt = $("#" + label.prop ("for") );
radioButt.prop ("checked", "checked");
label.css ("background", "lime");
return false; // End loop
}
} );
}
else {
alert ("I don't know how to answer: '" + this.textContent + "'");
$(this).css ("background", "pink");
}
if ( answerTxt && ! bFoundAnswer) {
alert ("The page does not have the specified answer for the question: '" + this.textContent + "'");
$(this).css ("background", "pink");
}
} );
function getAnswer (questionText) {
for (var J = answerKey.length - 1; J >= 0; --J) {
var zRegExp = new RegExp (answerKey[J].q, 'i');
if (zRegExp.test (questionText) )
return answerKey[J].a;
}
return null;
}
