JavaScript将XML转成JSON的方法
JavaScript代码：
// Changes XML to JSON
function xmlToJson(xml) {
// Create the return object
var obj = {};
if (xml.nodeType == 1) { // element
// do attributes
if (xml.attributes.length > 0) {
obj["@attributes"] = {};
for (var j = 0; j < xml.attributes.length; j++) {
var attribute = xml.attributes.item(j);
obj["@attributes"][attribute.nodeName] = attribute.nodeValue;
}
}
} else if (xml.nodeType == 3) { // text
obj = xml.nodeValue;
}
// do children
if (xml.hasChildNodes()) {
for(var i = 0; i < xml.childNodes.length; i++) {
var item = xml.childNodes.item(i);
var nodeName = item.nodeName;
if (typeof(obj[nodeName]) == "undefined") {
obj[nodeName] = xmlToJson(item);
} else {
if (typeof(obj[nodeName].length) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xmlToJson(item));
}
}
}
return obj;
};
XML代码：
<ALEXA VER="0.9" URL="davidwalsh.name/" HOME="0" AID="=">
<SD TITLE="A" FLAGS="" HOST="davidwalsh.name">
<TITLE TEXT="David Walsh Blog :: PHP, MySQL, CSS, Javascript, MooTools, and Everything Else"/>
<LINKSIN NUM="1102"/>
<SPEED TEXT="1421" PCT="51"/>
</SD>
<SD>
<POPULARITY URL="davidwalsh.name/" TEXT="7131"/>
<REACH RANK="5952"/>
<RANK DELTA="-1648"/>
</SD>
</ALEXA>
JSON结果：
{
"@attributes": {
AID: "=",
HOME: 0,
URL: "davidwalsh.name/",
VER: "0.9",
},
SD = [
{
"@attributes": {
FLAGS: "",
HOST: "davidwalsh.name",
TITLE: A
},
LINKSIN: {
"@attributes": {
NUM: 1102
}
},
SPEED: {
"@attributes": {
PCT: 51,
TEXT: 1421
}
},
TITLE: {
"@attributes": {
TEXT: "David Walsh Blog :: PHP, MySQL, CSS, Javascript, MooTools, and Everything Else",
}
},
},
{
POPULARITY: {
"@attributes": {
TEXT: 7131,
URL: "davidwalsh.name/"
}
},
RANK: {
"@attributes": {
DELTA: "-1648"
}
},
REACH: {
"@attributes": {
RANK = 5952
}
}
}
]
}
例：
json转换成XML后，对应的JS文件要怎么改？
$(function() {
$('#logout').click(function(){
top.location.href = "../login.html";
});
$("#tree").tree( {
url : "../data/menu.json",
onClick : doMenuClick
});
function doMenuClick(node) {
if ($("#tree").tree("isLeaf", node.target) == false)
return;
var id = node.id;
var text = node.text;
if (!id) return;
var elTab = parent.$('#mainTabs');
if (elTab.tabs('exists', text)) {
elTab.tabs('select', text);
} else {
var url = '../TheReport/' + id + '.html';
var content = '<div style="width:100%;height:100%;overflow:hidden;">'+
'<iframe src="' + url + '" scrolling="auto" style="width:100%;height:100%;border:0;" ></iframe></div>';
elTab.tabs('add', {
title : text,
content : content,
closable : true
});
}
}
});
上面 menu.json文件改成menu.xml文件后，这些代码需要改的什么？
<?xml version="1.0" encoding="GB2312"?>
<myfile>
<title>tttt</title>
<author>ajie</author>
<email>ajie@aolhoo.com</email>
<date>20010115</date>
</myfile>
HTML/JS：
<html>
<head>
<script language="JavaScript" for="window" event="onload">
var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async="false";
xmlDoc.load("myfile.xml");
root = xmlDoc.documentElement;
//nodes = xmlDoc.documentElement.childNodes;
document.all("title").innerText = root.childNodes.item(0).text;
document.all("author").innerText = root.childNodes.item(1).text;
document.all("email").innerText = root.childNodes.item(2).text;
document.all("date").innerText = root.childNodes.item(3).text;
</script>
<title>在HTML中调用XML数据</title>
</head>
<body bgcolor="#FFFFFF">
<b>标题: </b>
<span id="title"> </span>
<b>作者: </b>
