大神！为什么我的<body>里面的<img >图片显示不出来呢，难道是下面的js函数问题？

<html xmlns=http://www.w3.org/1999/xhtml>
<head>
<meta charset="utf-8" />
<script type="text/javascript" src="ceshi.js"></script> </head>
<body>
           <img src="aa.jpg" width="200" height="200"/>
                <div class="">
                  <script type="text/javascript">
     window.onload = function(){
                         var html = [];
                         for (var i = 0; i < yixuan_navs.length; i++) {
                                 var item = yixuan_navs[i];
                                 var child = item.children;
                               html.push("<div id='" + item.id + "'>" + item.name + "</div>");
                               html.push("<ul>");                           for (var j = 0; j < child.length; j++) {
                                html.push("<li id='" + child[j].id + "'><a href='" + child[j].url + "'>" + child[j].name + "</a></li>");
                     }                    html.push("</ul>");
                }                document.write(html.join(""));
            };
</script>
             </div> </body>
</html>

<img src="aa.jpg" width="200" height="200"/>
是这个图片显不出来么？      你确定图片和这个在同一个目录下？
你把document.write()改成 alert(html.join(""))先试试
改成alert后图片显示出来了，可是js输出的内容就不在图片下方了，要的就是html页面里图片下面是js输出的内容
就是<img>图片显示不出来<html>

                        var child = item.children;
                        html.push("<div id='" + item.id + "'>" + item.name + "</div>");
                        html.push("<ul>");                        for (var j = 0; j < child.length; j++) {
                            html.push("<li id='" + child[j].id + "'><a href='" + child[j].url + "'>" + child[j].name + "</a></li>");
                        }

                    }
                    alert(html.join(""));
                };
</script>
</div>
</body>
</html>
那就这样
document.getElementById("img下面的id").innerHTML = html.join("");
document.write()不常用
                        html.push("</ul>");
                    }
                    document.getElementById("img").innerHTML = html.join("");
                };
</script>
是这样写的吗，刚才试了试，不行啊
不是
我的意思是img下面的div的id
<body
<img src="aa.jpg" alt=""/><br>
<div >
这儿，给img下的div标签起个id名
例如
<body
<img src="aa.jpg" alt=""/><br>
<div id="divId">js是
document.getElementById("divId").innerHTML = html.join("");
不加id也可以这样
document.body.getElementsByTagName("div")[0].innerHTML = html.join("");
