代码没贴完整
AMinitSymbols()
AMprocessNode()
2个都是自定义的方法而你的代码中没有2个方法的具体实现

是这样的吧？

看了下源代码
感觉最主要的是这个function 给你注释了

function preview() {
if (document.getElementById("inputText") != '') {// 判断表单页面id值为inputText 是否为空
var str = document.getElementById("inputText").value; // 如果不为空把里面的值赋给var类型的 str变量
var outnode = document.getElementById("outputNode");// 得到表单页面id值是outputNode的value 并赋值给var类型的 outnode变量
var newnode = AMcreateElementXHTML("div"); // 通过AMcreateElementXHTML方法（作者自定义的）也是赋值
newnode.setAttribute("id","outputNode");//用setAttribute方法把值outputNode 赋值给 newnode（应该是个集合）对象的 id属性
outnode.parentNode.replaceChild(newnode,outnode);// 这一句是替换外部连接文件为了兼容各种浏览器
outnode = document.getElementById("outputNode"); // 也是和上面一样赋值语句
var n = outnode.childNodes.length; // 得到var outnode 子节点的长度
for (var i = 0; i < n; i++)// 用得到的长度n 做循环
outnode.removeChild(outnode.firstChild); //把outnode的第一个子节点删除
outnode.appendChild(document.createComment("`"+str+"`"));// 把outnode中n个元素连接起来
AMprocessNode(outnode,true); // 调用AMprocessNode方法（作者自定义的）把outnode作为参数传过去
}
}
