Question

下面是我的代码，我想在div上放置（堆叠）卡片..但只有第一张卡位于-20px，其他所有都被放置为0px..position ....如何解决？ :( function myFunction（）{ 为（J = 1; J＆LT; 8; J ++）{

            for(i=1;i<7;i++){
                if(j<2){
                var x = document.createElement("IMG");
                x.setAttribute("src", "AllCards/cvr.png");
                x.setAttribute("id", "r"+j);
                x.setAttribute("width", "auto");
                x.setAttribute("height", "auto");
                x.setAttribute("alt", "one");
                document.getElementById("c"+i).appendChild(x);
                alert("r"+j+" c"+i);

                //document.getElementById("r"+j).style.position = "relative";
                //document.getElementById("r"+j).style.top="20px";

                }
                else if(j<3){

您是否考虑过将css类设置为属性并将定位细节放入其中？ e.g。

x.setAttribute("class", "rClass");

的CSS：

.rClass {
   top:-80px;
   position:relative;
}
