先生需要一个测试系列的代码来逐个显示数据库中的随机问题（不重复）。 [英] Sir need a code for the test series to display random questions (not repeating) from database one by one.

问题描述

我想在html和javascript中对测试系列进行编码，其中随机问题应该从数据库中逐一出现，然后在测试链接关闭后，所有答案都应该按照问题出现的方式显示解决方案。如果用户输入错误，则显示正确答案。



我尝试过：

 <   meta     http-equiv   = 内容 - 语言    content   =   zh-CN >  
 <   title  > 在线测验
 
 var rightAnswer = new Array（）; 
 var questPerPage = 2; 
 var quests = Array（Quest0，Quest1，Quest2，Quest3，Quest4，Quest5，Quest6，Quest7）; 
 var answers = Array（）; 
 answers [0] =数组（1，answer1，answer2，answer3，answer4）
 answers [1] =数组（2，answer5，answer6， answer7，answer8）
 answers [2] =数组（3，answer9，answer10，answer11，answer12）
 answers [3] =数组（4， answer13，answer14，answer15，answer16）
 answers [4] =数组（4，answer17，answer18，answer19，answer20）
 answers [5] =数组（3，answer21，answer22，answer23，answer24）
 answers [6] =数组（2，answer25，answer26，answer27， answer28）
 answers [7] =数组（1，answer29，answer30，answer31，answer32）
 
函数showQuestion（）{
 htmlStr = ; 
 for（qpp = 0; qpp& lt; questPerPage; qpp ++）{
 
q = Math.floor（Math.random（）* quests.length）
 htmlStr + =Q ＃+ qpp +：+ quests [q] +<   br  >  A：; 
 
 rightAnswer [qpp] = answers [q] [0] -1; 
 
 for（a = 1; a& lt; answers [q] .length; a ++）{
 htmlStr + =<  输入   名称  ='  ansr+ qpp +'   类型  ='  radio'    value   =' ' >  <   label  < span class =code-keyword>> + answers [q] [a] +<   / label  > 
} 
 htmlStr + =<   p  > ; 
} 
 document.getElementById（myQuiz）。innerHTML = htmlStr 
} 
 
函数检查（）{
 for（ra = 0; ra& amp; ; lt; rightAnswer.length; ra ++）{
 radios = document.getElementsByName（ansr+ ra）
 if（radios [rightAnswer [ra]]。checked）{
 alert（答案＃+ ra +是正确的）; 
}其他{
 alert（答案＃+ ra +不正确）; 
} 
} 
 showQuestion（）
}

所以请你给出相同的代码。

不，因为这不是它的工作原理：我们不做你的功课：这是有原因的。它就是为了让你思考你被告知的事情，并试着理解它。它也在那里，以便您的导师可以识别您身体虚弱的区域，并将更多的注意力集中在补救措施上。



想一想，关于你是什么需要做的是确保非重复序列。提示：随机数就是：随机数。因此，您需要提前生成问题列表，将其存储在某个位置，然后从中获取问题。是否有任何地方可以在页面边界的Javascript中存储信息？



如果您遇到特定问题，请询问相关问题，我们会尽力提供帮助。但我们不打算为你做这一切！

i want to code the test series in html and javascript in which the random question should appear from database and one by one and then after the test link is closed then all the answers should be display acc to the way question appeared with the solutions. and if the user enter wrong then show correct answer.

What I have tried:

<meta http-equiv="Content-Language" content="en-us">
<title>Online Quiz

var rightAnswer=new Array();
var questPerPage=2;
var quests=Array("Quest0","Quest1","Quest2","Quest3","Quest4","Quest5","Quest6","Quest7");
var answers=Array();
answers[0]=Array(1,"answer1","answer2","answer3","answer4")
answers[1]=Array(2,"answer5","answer6","answer7","answer8")
answers[2]=Array(3,"answer9","answer10","answer11","answer12")
answers[3]=Array(4,"answer13","answer14","answer15","answer16")
answers[4]=Array(4,"answer17","answer18","answer19","answer20")
answers[5]=Array(3,"answer21","answer22","answer23","answer24")
answers[6]=Array(2,"answer25","answer26","answer27","answer28")
answers[7]=Array(1,"answer29","answer30","answer31","answer32")

function showQuestion(){
htmlStr="";
for(qpp=0;qpp&lt;questPerPage;qpp++){

q=Math.floor(Math.random()*quests.length)
htmlStr+="Q#"+qpp+": "+quests[q]+"<br>A: ";

rightAnswer[qpp]=answers[q][0]-1;

for(a=1;a&lt;answers[q].length;a++){
htmlStr+="<input name='ansr"+qpp+"' type='radio' value=''><label>"+answers[q][a]+"</label>  "
}
htmlStr+="<p>";
}
document.getElementById("myQuiz").innerHTML=htmlStr
}

function check(){
for (ra=0;ra&lt;rightAnswer.length;ra++){
radios=document.getElementsByName("ansr"+ra)
if (radios[rightAnswer[ra]].checked){
alert("The Answer#"+ra+" is correct");
}else{
alert("The Answer#"+ra+" is incorrect");
}
}
showQuestion()
}

so please can you give the code for the same.

No, because that's not how it works: We do not do your homework: it is set for a reason. It is there so that you think about what you have been told, and try to understand it. It is also there so that your tutor can identify areas where you are weak, and focus more attention on remedial action.

Have a think about it, and about what you need to do to ensure a non-repeating sequence. Hint: random numbers are just that: random. So you need to generate a list of questions in advance, store it somewhere, and fetch a question at a time from it. Is there anywhere you can store information in Javascript across page boundaries?

If you meet a specific problem, then please ask about that and we will do our best to help. But we aren't going to do it all for you!
