Question

问：如何从源div（id =＆＃34; p2＆＃34;）中获取包含一些图像的目标div（id =＆＃34; p1＆＃34;）内的点击图像。

当前结果：仅显示最后一张图片。如果我错了，请提出其他逻辑。 P.S只需要javascript。

在{document.getElementById（＆＃34; p1＆＃34;）。innerHTML =＆＃34;＆＃34 ;;}之前需要一些逻辑，即脚本代码的最后一行。因此，显示精确点击的图像而不是最后一个图像，这是根据当前逻辑

以下是代码段：

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<style>
.main{
    height:400px;
    width:200px;
    margin:0px auto}
.p1{

        height:200px;
        width:200px;
        background-size: 100% auto;
        border-style:outset;
        border-radius:2px;
        }
.images{
        width:50px;
        height:50px;
        border-radius:5px;
        }
</style>

<body >
<div class="main" >
<div id="p1" class="p1"><img src="" alt="" /></div>
<div id="p2">
 <input type="image" class="images"  id="obj0" name="obj" onclick="myFunction()" src="http://www.picgifs.com/clip-art/flowers-and-plants/flowers/clip-art-flowers-511058.jpg"/></br>
 <input type="image" class="images" id="obj1" name="obj" onclick="myFunction()" src="http://www.picgifs.com/clip-art/flowers-and-plants/flowers/clip-art-flowers-380016.jpg"/></br>
 <input type="image" class="images" id="obj2" name="obj" onclick="myFunction()" src="http://www.picgifs.com/clip-art/flowers-and-plants/flowers/clip-art-flowers-293063.jpg"/></br>
 <input type="image" class="images" id="obj3" name="obj" onclick="myFunction()" src="http://www.picgifs.com/clip-art/flowers-and-plants/flowers/clip-art-flowers-611834.jpg"/></br>
</div>
<script>
function myFunction(){
                    var x=document.getElementsByName("obj");
                    y=x.length;
                    for(var i=0;i<y;i++){
                     hi = document.getElementById('obj'+i).src;
                     //alert(hi);  uncommenting I can get url of each picture
                     document.getElementById("p1").innerHTML="<img src='"+hi+"' height=100px ;width=100px centre />";
                    }

}
 </script> 
 </div>
</body>

提前致谢！

你需要有一个参数来传递刚刚点击的东西的ID。然后，您需要获取已传递的ID的属性。

你走了：
