能否在某个网页元素后面增加东西？
<div>
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>
......
......
......
<div>
能否在id123的后面（而不是后部）增加文本或者HTML元素？变成
<div>
<div id= "id123 "> 456 </div> 这里是我添加的文本 <span> 这里是我添加的元素 </span>
<div id= "id789 "> abc </div>
......
......
......
<div>
[解决办法]
这样行不?
<html>
<head>
<meta http-equiv= "Content-Type " content= "text/html; charset=gb2312 ">
<title> new page </title>
<script>
function a(){
var oDiv=document.getElementById( "id123 ");
oDiv.outerHTML=oDiv.outerHTML+ "这里是我添加的文本 <span> 这里是我添加的元素 </span> ";
alert(document.body.innerHTML);
}
</script>
</head>
<body onload= "a() ">
<div>
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>
</div>
</body>
</html>
[解决办法]
可以：
<script type= "text/javascript ">
function insd(){
var mydiv=document.getElementById( "id123 ");
myspan=document.createElement( "span ");
myspan.innerHTML= "这里是我添加的元素 ";
mydiv.parentNode.insertBefore(myspan,mydiv.nextSibling);
}
</script>
<div id= "id123 "> 456 </div> <div id= "id789 "> abc </div>
......
......
......
</div>
<input type= "button " value= "插入 " onclick= "insd() " />

[解决办法]
看错要求:
改个函数即可...
<script type= "text/javascript " src= "http://code.jquery.com/jquery-latest.pack.js "> </script>
<script type= "text/javascript ">
$(document).ready(function(){
$( "#id123 ").after( '这是俺的文本 <span> 文本哇 </span> 测试 ');
});
</script>
<div id= "hjx ">
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>
<div>
[解决办法]
在随意指定的位置应该不行吧，添加到一个容器的后面应该没有问题的，从你的描述来看除非先定位一个容器容然后再加东西进去，有高手出来再看看。
[解决办法]
最好放在容器里
遵循DOM标准
[解决办法]
<script type= "text/javascript " src= "http://code.jquery.com/jquery-latest.pack.js "> </script>
<script type= "text/javascript ">
$(document).ready(function(){
$( "div/div ").click(function(){
var id=$(this).attr( 'id ');
$(this).after( '在后 '+id+ '面加入的这串文本 ');
});
});
</script>
<div id= "hjx ">
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>
<div id= "id123 "> 456 </div>
<div id= "id789 "> abc </div>

方法：parentNode.insertBefore(newNode,currentChildNode)
功能：往parentNode节点中的currentChildNode子节点的前面插入newNode
[解决办法]
注意没有insertAfer方法
