Document.createCDATASection()

语法

var CDATASectionNode = document.createCDATASection(data);

• CDATASectionNode 是一个 CDATA 片段节点。
• data 包含了要被添加至 CDATA 片段的数据的字符串。

示例

var docu = new DOMParser().parseFromString("<xml></xml>", "application/xml");

var cdata = docu.createCDATASection("Some <CDATA> data & then some");

docu.getElementsByTagName("xml")[0].appendChild(cdata);

alert(new XMLSerializer().serializeToString(docu));
// Displays: <xml><![CDATA[Some <CDATA> data & then some]]></xml>

备注

• This will only work with XML, not HTML documents (as HTML documents do not support CDATA sections); attempting it on an HTML document will throw NOT_SUPPORTED_ERR.
• Will throw a NS_ERROR_DOM_INVALID_CHARACTER_ERR exception if one tries to submit the closing CDATA sequence ("]]>") as part of the data, so unescaped user-provided data cannot be safely used without with this method getting this exception (createTextNode() can often be used in its place).
