Question

这是我第一次在Stackoverflow上询问，

这是我的HTML代码，

＆＃13;

<div id="accordion" style="height: auto;">
  <h3>Question 1</h3>
 <div>
  <div id="q1">
	Sending messages from another user's email address is called what?  
    <ul>
	<li><button type="button" class="btn btn-secondary btn-sm optionbutton" data-optionId="option1">Spamming</button></li>
	<li><button type="button" class="btn btn-secondary btn-sm  optionbutton" data-optionId="option2">Trolling</button></li>
	<li><button type="button" class="btn btn-secondary btn-sm optionbutton answer  active clicked" data-optionId="option3">Spoofing</button></li>
	<li><button type="button" class="btn btn-secondary btn-sm optionbutton" data-optionId="option4">Pharming</button></li>
	</ul>
	</div> <!-- q1 -->
  </div>
<h3>Question 2</h3>
<div>
	<div id="q2">
    How many zebibytes are in a yobibyte?
    <ul>
    <li><button type="button" class="btn btn-secondary btn-sm optionbutton answer" data-optionId="option1">1,024</button></li>
    <li><button type="button" class="btn btn-secondary btn-sm optionbutton" data-optionId="option2">1,048,576</button></li>
    <li><button type="button" class="btn btn-secondary btn-sm optionbutton" data-optionId="option3">1,000,000</button></li>
    <li><button type="button" class="btn btn-secondary btn-sm optionbutton active clicked" data-optionId="option4">1,000,000,000</button></li>
	   </ul>
	  </div><!-- q2 -->
    </div>

＆＃13;

这是我的Jquery代码

＆＃13;

var q1input = 0;
var q2input = 0;
var q3input = 0;
var q4input = 0;
var q5input = 0;
    var optionele1 = $("#q1").find("button.active.clicked");
	var optionele2 = $("#q2").find("button.active.clicked");
	var optionele3 = $("#q3").find("button.active.clicked");
	var optionele4 = $("#q4").find("button.active.clicked");
	var optionele5 = $("#q5").find("button.active.clicked");
	var answerele1 = $("#q1").find("button.answer");
	var answerele2 = $("#q2").find("button.answer");
	var answerele3 = $("#q3").find("button.answer");
	var answerele4 = $("#q4").find("button.answer");
	var answerele5 = $("#q5").find("button.answer");
	if( optionele1.is(answerele1)	){	q1input = 100;	}else{}
	if( optionele2.is(answerele2)	){	q2input = 100;	}else{}
	if( optionele3.is(answerele3)	){	q3input = 100;	}else{}
	if( optionele4.is(answerele4)	){	q4input = 100;	}else{}
	if( optionele5.is(answerele5)	){	q5input = 100;	}else{}

问题是，我应该如何比较jquery中的两个元素？或者我的代码中有任何错误的语法？请帮忙。我被困在这里。

Answer 1

您需要将jQuery对象中的第一个元素相互比较。例如：

if( $('.sel1')[0] == $('.sel2')[0] )

因此，您的代码应如下所示（请注意，也不需要else块）：

if( optionele1[0] == answerele1[0] ) { q1input = 100; }
// etc.

在Jquery中比较If else条件中的元素
