XML operation implementation code in javascript_javascript skills

JavaScript side:

Copy code The code is as follows:

//Initialization page
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 = ""
obj.label " " ";
}

page = 1;
changeImage(page);

var pageManager = document.getElementById("div_page");
pageManager.innerHTML = "Previous page " "
"Next page


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

" obj2.name "

" obj2.content "

";
}

//Parse the .dibi file.
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;
}

//Determine the browser type. Support 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; //Current page
var pageCount; //Total number of pages

/ /Change page image based on click
function changeImage(page1){
page = page1;
var divimg = document.getElementById("div_img");
divimg.innerHTML = "";
}

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


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

HTML side:

Copy the code The code is as follows:

< ;script language="javascript" type="text/javascript" charset='gbk' src="xmlhelper.js">
