JavaScript

久しぶりに書きました.今でもHTML 5はチケット遊びにすぎないような気がします.w 3 cの標準が早く登場することを望んで、各種ブラウザの互換性の問題とサポートの程度を死なせないでください.の

JavaScript:

//     
function init() {
    var ary = JSONToArray(XMLReader("node","content.dibi"));
    var divtoc = document.getElementById("div_toc");
    pageCount = ary.length;
    for(k = 0; k < ary.length; k++){
        obj = eval('(' + ary[k] + ')');
        divtoc.innerHTML += "<a href='javascript:changeImage(" + obj.page.substring(obj.page.length-1) + ")'>" 
                         + obj.label + "</a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;";
    }

    page = 1;
    changeImage(page);

    var pageManager = document.getElementById("div_page");
    pageManager.innerHTML = "<a href='javascript:changePage(0)'>   </a>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;"
                          + "<a href='javascript:changePage(1)'>   </a><br/><br/>";

    var ary2 = JSONToArray(XMLReader("meta","content.dibi"));
    var divmeta = document.getElementById("div_meta");
    var styStr = "<table>"
    for(l = 0; l < ary2.length; l++){
        obj2 = eval('(' + ary2[l] + ')');
        styStr += "<tr><td>" + obj2.name + "</td><td>" + obj2.content + "</td></tr>";
    }
    divmeta.innerHTML = styStr + "</table>";
}

//  .dibi   。
function XMLReader(key,fileName) {
    var parse = BrowserValidator();
        parse.load(fileName);
    var json = "";
    try{
        var dom = parse.documentElement;
        var attrLength = 0;
        for (i = 0; i < dom.getElementsByTagName(key).length; i++) {
            attrLength = dom.getElementsByTagName(key)[i].attributes.length;
            objMsg = ",{";
            for(j = 0; j < attrLength; j++){
                objMsg += "'" + dom.getElementsByTagName(key)[i].attributes[j].name
                     + "':'" + dom.getElementsByTagName(key)[i].attributes[j].value + "',"; 
            }
            objMsg = objMsg.substring(0,objMsg.length-1);  
            json += objMsg + "}";
        }
        json = json.substring(1);
    }catch(e){}
    return json;
}

//       。   IE ，fireFox。
function BrowserValidator(){
    var result;
    if(!window.DOMParser && window.ActiveXObject) {
        result = new ActiveXObject("Microsoft.XMLDOM"); 
        result.async = false; 
    }
    else if(document.implementation && document.implementation.createDocument) {
        result = document.implementation.createDocument("", "", null);  
        result.async = false; 
    }
    return result;
}

var page = 1;   //   
var pageCount;  //   

//          
function changeImage(page1){
    page = page1;
    var divimg = document.getElementById("div_img");
    divimg.innerHTML = "<img width='500' src = 'images/" + page +".jpg'/>";
}

//     
function changePage(flag){
    if(flag == 0 && page > 1){
        page--;
    }
    if(flag == 1 && page < pageCount){
        page++;
    }
    changeImage(page);
}


//  JSON        
function JSONToArray(json){
    return json.replace(new RegExp("},", "g"), "}|").split("|");
}

HTML:

<html>
<head>
    <title></title>
    <script language="javascript" type="text/javascript" charset='gbk' src="xmlhelper.js"></script>
</head>
<body onload="init()">
<div id="div_toc"></div>
<div id="div_img"></div>
<div id="div_page"></div>
<div id="div_meta"></div>
</body>
</html>
