jQuery通过ajax异步获取xml文件及xml转json字符串
1，ajax通过异步读取xml文件
<script>
$(function () {
//异步加载xml文件
$.ajax({
url:"vod/mp4/20180323173011-25701533_0_video.xml",
type:"POST",
async: true, //异步请求
cache: false,
dataType: "text", //返回值为文本(xml)
success:function (result){
var jsonvalue= xmlStr2XmlObj(result); //将xml文件转换为json对象
console.log(jsonvalue)
},
error:function (e) {
console.log("异步失败:"+e);
}
});
});
</script>
2,通过js将xml文件转换为json数据
<script>
/**
* xml字符串转换json数据
* @param {
Object} xml
*/
function xmlObj2json(xml) {
var xmlObj = xmlStr2XmlObj(xml);
var jsonObj = {
};
if (xmlObj.childNodes.length > 0) {
jsonObj = xml2json(xmlObj);
}
return jsonObj;
}
/**
* xml字符串转换xml对象数据
* @param {
Object} xmlStr
*/
function xmlStr2XmlObj(xmlStr) {
var xmlObj = {
};
if (document.all) {
var xmlDom = new ActiveXObject("Microsoft.XMLDOM");
xmlDom.loadXML(xmlStr);
xmlObj = xmlDom;
} else {
xmlObj = new DOMParser().parseFromString(xmlStr, "text/xml");
}
return xmlObj;
}
/**
* xml转换json数据
* @param {
Object} xml
*/
function xml2json(xml) {
try {
var obj = {
};
if (xml.children.length > 0) {
for (var i = 0; i < xml.children.length; i++) {
var item = xml.children.item(i);
var nodeName = item.nodeName;
if (typeof(obj[nodeName]) == "undefined") {
obj[nodeName] = xml2json(item);
} else {
if (typeof(obj[nodeName].push) == "undefined") {
var old = obj[nodeName];
obj[nodeName] = [];
obj[nodeName].push(old);
}
obj[nodeName].push(xml2json(item));
}
}
} else {
obj = xml.textContent;
}
return obj;
} catch (e) {
console.log(e.message);
}
}
</script>
