当src存储在数组中时，通过javascript更改imgsrc

我正在尝试更改页面加载时图像的来源，但不是加载图像本身，而是显示其位置的字符串。很可能是一个简单的解决方案，但我看不到

<form id="form1"><h1 id="dude">question?</h1><br>
                    <h2>
                        <label for ="answer1" id="label1"><img src="imgs//img.png" id="img1" width="150" height = "150"></label>
                        <input type="radio" name="answer" id="answer1">
                    </h2><br>
                    <h2>
                        <label for ="answer2" id="label2"><img src="imgs//img.png" id="img2" width="150" height = "150"></label>
                        <input type="radio" name="answer" id="answer2">
                    </h2><br>
                    <h2>
                        <label for="answer3" id="label3"><img src="imgs//img.png" id="img3" width="150" height = "150"></label>
                        <input type="radio" name="answer" id="answer3">
                    </h2>
                    <h2>
                        <label for="answer4" id="label4"><img src="imgs//img.png" id="img4" width="150" height = "150"></label>
                        <input type="radio" name"answer" id="answer4">
                    </h2>
                </form>

如果您有任何想法，我们将不胜感激。

您实际上并没有更改图像的src，而只是更改Label元素的innerHtml

您需要从标签中获取图像元素，然后执行image.src=coi[currentQuestion][1]

你可以用这个

 var mulChoiImg = new Array('Which picture do you like most', 'imgs/img2.png','imgs/img2.png','imgs//img2.png','imgs/img2.png');

function popMulC(){
 document.getElementById("label1").innerHTML = "<img src=" + mulChoiImg[1] + "/>";
 }

您正在使用双斜杠imgs//删除一个。仍然没有更改吗？

 var mulChoiImg = new Array('Which picture do you like most', 'imgs/img2.png','imgs/img2.png','imgs//img2.png','imgs/img2.png');

function popMulC(){
 document.getElementById("label1").innerHTML = "<img src=" + mulChoiImg[1] + "/>";
 }
