javascript生成解析dom的CDATA类型的字段的代码
2018-09-23 20:31
两段demo代码如下(forieonly)：
<scripttype=text/javascript>
//demo1
varxmlDoc=newActiveXObject(Msxml2.DOMDocument);
varroot;
varCDATASection;
xmlDoc.async=false;
xmlDoc.loadXML(<a/>);
root=xmlDoc.documentElement;
CDATASection=xmlDoc.createCDATASection(HelloWorld!);
root.appendChild(CDATASection);
b=xmlDoc.createElement(Test)
b.text=hahahahaha
root.appendChild(b);
alert(root.xml);
for(i=0;i<root.childNodes.length;i++)
{
if(root.childNodes[i].nodeType==4)
alert(root.childNodes[i].nodeValue)
}
</script>
<scripttype=text/javascript>
//demo2
varxmlDoc=newActiveXObject(Msxml2.DOMDocument);
xmlDoc.async=false;
xmlDoc.loadXML(<a><![CDATA[aaaaaaaaaaaaaaaaaaaaa]]></a>);
root=xmlDoc.documentElement;
for(i=0;i<root.childNodes.length;i++)
{
if(root.childNodes[i].nodeType==4)
alert(root.childNodes[i].nodeValue)
}
</script>
