如何在jQuery中添加onClick状态？

Question

我有以下代码添加和删除一个类。但我希望在处于活动状态时在图像上添加另一个类，并在处于非活动状态时将其删除。问题是我可以添加，但是对于所有元素都将是活动的，不仅仅是打开的那个元素。有没有人知道如何解决这个问题？

$(document).ready(function() {
function close_answer_section() {
    $('.question-text').removeClass('active');
    $('.plus').attr("src","http://tdhtestserver.herobo.com/plus-eclipse.png");
    $('.answer-section-content').slideUp(300).removeClass('open');
}

$('.question-text').click(function(e) {
    var currentAttrValue = $(this).attr('href');
    if($(this).is('.active')) {
        close_answer_section();
    }else {
        close_answer_section();
        $(".plus").attr("src","http://tdhtestserver.herobo.com/plus-eclipse-active.png");
        $(this).addClass('active');
        $('.questions ' + currentAttrValue).slideDown(300).addClass('open'); 
    }

    e.preventDefault();
});
});

<强>更新：

$(document).ready(function() {
	function close_answer_section() {
		$('.question-text').removeClass('active');
        $('.plus').attr("src","http://tdhtestserver.herobo.com/plus-eclipse.png");
		$('.answer-section-content').slideUp(300).removeClass('open');
	}

	$('.question-text').click(function(e) {
		var currentAttrValue = $(this).attr('href');
		if($(this).is('.active')) {
			close_answer_section();
		}else {
			close_answer_section();

			$(this).find('img').attr("src","http://tdhtestserver.herobo.com/plus-eclipse-active.png");
        $(this).addClass("active");
			$('.questions ' + currentAttrValue).slideDown(300).addClass('open'); 
		}

		e.preventDefault();
	});
});
