This article mainly introduces in detail the implementation method of javascript九宫格Picture. It has certain reference value. Interested friends can refer to it.
Today I will make a simple nine-square grid puzzle. The most troublesome thing for me is to click to start disrupting the position of the pictures. At the beginning, I checked related blogs on Baidu and took many detours. Finally, after reading many examples, I wrote my own method.
<script> //打乱图片方法 function fun(){ var x = []; var y ; for(var i=1;i<10;i++){ var p = document.getElementById("d"+i+""); p.removeChild(document.getElementById("img"+i+"")); } for(var i=1;i<10;i++){ var img = document.createElement('img'); //动态创建img标签 var p1 = document.getElementById("d"+i+""); var p = [1,2,3,4,5,6,7,8,9]; //用p[]数组保存图片的代号 var j = Math.round(Math.random()*8); //通过随机数j产生随机图片代号p[j] for ( var u=0 ; u < x.length ; u++ ) //遍历x[]数组防止后面出现与前面一样的图片代号 { if ( x[u] == p[j] ) { y = x[u]; break; } } if(p[j]==y){ i-=1; continue; }else{ img.setAttribute("src","images/tiger_0"+p[j]+".gif"); img.id = "img"+i+""; } p1.appendChild(img); x.push(p[j]); //添加已经出现的图片号数进入x[]数组 } dragdrop();//拖动图片方法 } </script>
