一个实用的 Javascript XML to JSON Object 对象的转换 （JQuery）

一个用来将xml文件转换成对象的插件 xml文件如下 TreeView ListGrid ListBox 1 生成的对象为: 调用 var xml = $.loadXML("PluginConf.xml"); var obj = $(xml).toObject().get(0); alert(obj.pool); 以下是源码下载 /** * 转换xml为对象形式 * @return {Object} * @param {XMLHttpRequest} elXML */ $.fn.toObject = function (){ if (this==null) return null; var retObj = new Object; buildObjectNode(retObj,/*jQuery*/this.get(0)); return $(retObj); function buildObjectNode(cycleOBJ,/*Element*/elNode){ /*NamedNodeMap*/ var nodeAttr=elNode.attributes; if(nodeAttr != null){ if (nodeAttr.length&&cycleOBJ==null) cycleOBJ=new Object; for(var i=0;icycleOBJ[nodeAttr[i].name]=nodeAttr[i].value; } } var nodeText="text"; if (elNode.text==null) nodeText="textContent"; /*NodeList*/ var nodeChilds=elNode.childNodes; if(nodeChilds!=null){ if (nodeChilds.length&&cycleOBJ==null) cycleOBJ=new Object; for(var i=0;iif (nodeChilds[i].tagName!=null){ if (nodeChilds[i].childNodes[0]!=null&&nodeChilds[i].childNodes.length<=1&&(nodeChilds[i].childNodes[0].nodeType==3||nodeChilds[i].childNodes[0].nodeType==4)){ if (cycleOBJ[nodeChilds[i].tagName]==null){ cycleOBJ[nodeChilds[i].tagName]=nodeChilds[i][nodeText]; }else{ if (typeof(cycleOBJ[nodeChilds[i].tagName])=="object"&&cycleOBJ[nodeChilds[i].tagName].length){ cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length]=nodeChilds[i][nodeText]; }else{ cycleOBJ[nodeChilds[i].tagName]=[cycleOBJ[nodeChilds[i].tagName]]; cycleOBJ[nodeChilds[i].tagName][1]=nodeChilds[i][nodeText]; } } }else{ if (nodeChilds[i].childNodes.length){ if (cycleOBJ[nodeChilds[i].tagName]==null){ cycleOBJ[nodeChilds[i].tagName]=new Object; buildObjectNode(cycleOBJ[nodeChilds[i].tagName],nodeChilds[i]); }else{ if (cycleOBJ[nodeChilds[i].tagName].length){ cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length]=new Object; buildObjectNode(cycleOBJ[nodeChilds[i].tagName][cycleOBJ[nodeChilds[i].tagName].length-1],nodeChilds[i]); }else{ cycleOBJ[nodeChilds[i].tagName]=[cycleOBJ[nodeChilds[i].tagName]]; cycleOBJ[nodeChilds[i].tagName][1]=new Object; buildObjectNode(cycleOBJ[nodeChilds[i].tagName][1],nodeChilds[i]); } } }else{ cycleOBJ[nodeChilds[i].tagName]=nodeChilds[i][nodeText]; } } } } } } } /** * @return {Element} * @param {String} _url */ $.loadXML = function (_url){ var ret; $.ajax({ type:"get", url:_url, async:false, dataType:"xml", success:function(xml){ ret = xml; } }); return ret.documentElement;
