初学javascript,学习中用到在IE中建立XML对象,于是写了一个简单的“库”。因为水平所限,肯定会有不恰当的地方,欢迎指正。
如果大家有知道现存的更好的东西,非常希望大家能将它推荐给我。
代码:
function XmlObject() { var oXml = new ActiveXObject("Microsoft.XMLDOM"); this.getXmlObj = function() { return oXml; } this.InitXmlObj = function() { oXml = new ActiveXObject("Microsoft.XMLDOM"); //对象 } this.isTop = function(oNode) { if (oNode === oXml) return true; return false; } this.AddTextNode = function(oParent, sKey, sValue) { if (this.isTop(oParent) == true) { //为顶级对象添加的节点不能超过一个 if (oXml.childNodes.length > 0) { //已经存在根节点,不继续添加 return null; } } var oNewNode = oXml.createElement(sKey); var oTextNode = oXml.createTextNode(sValue); oParent.appendChild(oNewNode); oNewNode.appendChild(oTextNode); return oNewNode; } this.AddAttrNode = function(oParentNode, sNodeName, sAttr, sValue) { if (this.isTop(oParent) == true) { //为顶级对象添加的节点不能超过一个 if (oXml.childNodes.length > 0) { //已经存在根节点,不继续添加 return null; } } var oNewNode = oXml.createElement(sNodeName); oParentNode.appendChild(oNewNode); oNewNode.setAttribute(sAttr, sValue); return oNewNode; } this.AddAttrTextNode = function(oParentNode, sNodeName, sNodeText, sAttrName, sAttrValue) { if (this.isTop(oParentNode) == true) { //为顶级对象添加的节点不能超过一个 if (oXml.childNodes.length > 0) { //已经存在根节点,不继续添加 return null; } } var oNewNode = oXml.createElement(sNodeName); var oTextNode = oXml.createTextNode(sNodeText); oParentNode.appendChild(oNewNode); oNewNode.setAttribute(sAttrName, sAttrValue); oNewNode.appendChild(oTextNode); return oNewNode; } this.getXmlStr = function() { return oXml.xml; } }
演示代码:
function onXml() { var oXmlOp = new XmlObject(); var oTop = oXmlOp; var oTop = oXmlOp.AddAttrTextNode(oXmlOp.getXmlObj(), "UserInfo", "", "class", "dianxin1005"); oXmlOp.AddAttrTextNode(oTop, "Subject", "Chinese", "Score", "98"); oXmlOp.AddAttrTextNode(oTop, "Subject", "Math", "Score", "77"); oXmlOp.AddAttrTextNode(oTop, "Subject", "English", "Score", "99"); alert(oXmlOp.getXmlStr()); }
生成的XML是:
<UserInfo class="dianxin1005"> <Subject Score="98"> Chinese </Subject> <Subject Score="77"> Math </Subject> <Subject Score="99"> English </Subject> </UserInfo>
