代碼沒貼完整
AMinitSymbols()
AMprocessNode()
2個都是自定義的方法而你的代碼中沒有2個方法的具體實現

網頁上數學公式的完美輸入和顯示靜態的HTML語言都能看懂就是JSP的語言就不明白是什麼意思了 ..

是這樣的吧？

看了下源代碼
感覺最主要的是這個function 給你注釋了

function preview() {
if (document.getElementById("inputText") != '') {// 判斷表單頁麵id值為inputText 是否為空
var str = document.getElementById("inputText").value; // 如果不為空把裏麵的值賦給var類型的 str變量
var outnode = document.getElementById("outputNode");// 得到表單頁麵id值是outputNode的value 並賦值給var類型的 outnode變量
var newnode = AMcreateElementXHTML("div"); // 通過AMcreateElementXHTML方法（作者自定義的）也是賦值
newnode.setAttribute("id","outputNode");//用setAttribute方法把值outputNode 賦值給 newnode（應該是個集合）對象的 id屬性
outnode.parentNode.replaceChild(newnode,outnode);// 這一句是替換外部連接文件為了兼容各種瀏覽器
outnode = document.getElementById("outputNode"); // 也是和上麵一樣賦值語句
var n = outnode.childNodes.length; // 得到var outnode 子節點的長度
for (var i = 0; i < n; i++)// 用得到的長度n 做循環
outnode.removeChild(outnode.firstChild); //把outnode的第一個子節點刪除
outnode.appendChild(document.createComment("`"+str+"`"));// 把outnode中n個元素連接起來
AMprocessNode(outnode,true); // 調用AMprocessNode方法（作者自定義的）把outnode作為參數傳過去
}
}
