Principle: html can not set coding, but xml can, we use xml, take the data to the past, it is OK.
Js core code:
/ Note: please use a more perfect way to create xmlDoc,xmlHtml objects. This is just a brief demonstration.
FunctiondoSubmit () {
Varstr=document.getElementById ("input1"). Value
/ / suppose str is the data you want to submit
Alert (str)
/ / "MSXML2.DOMDocument", "Microsoft.XMLDOM", "MSXML.DOMDocument", "MSXML3.DOMDocument"
VarxmlDoc=newActiveXObject ("MSXML2.DOMDocument")
/ / initialize the xml document object
XmlDoc.loadXML ("")
XmlDoc.documentElement.text=str;// is carried as content.
/ / if it is more convenient to use attributes to carry data, you can use the following methods
/ / xmlDoc.documentElement.setAttribute ("name", "msg")
/ / xmlDoc.documentElement.setAttribute ("value", str)
Alert (xmlDoc.xml); / / View the generated xml content
/ / "MSXML2.XMLHttp.5.0", "MSXML2.XMLHttp.4.0", "MSXML2.XMLHttp.3.0", "MSXML2.XMLHttp", "Microsoft.XMLHttp"
VarxmlHttp=newActiveXObject ("MSXML2.XMLHttp.5.0")
Varurl= "servlet/MyServlet?time=" + (newDate ()) .getTime ()
XmlHttp.open ("POST", url,false)
XmlHttp.send (xmlDoc); / / send the xml object
Alert (xmlHttp.responseText)
}
How to deal with Chinese when AJAX submits data
Servlet/action core code:
/ / read the xml data sent by ajax
SAXReaderxmlReader=newSAXReader ()
Documentdocument=null
Try {
Document=xmlReader.read (request.getInputStream ())
} catch (Exceptionex) {
System.err.println ("xml read failed, there may be no xml data")
Ex.printStackTrace ()
}
System.out.println ("received xml data:" + document.asXML ())
/ / parsing xml
Stringstr=document.getRootElement () .getText ()
System.out.println ("parsed data:" + str)
/ / return the result
Response.setContentType ("text/html;charset=UTF-8"); / / GBK is also fine, indicating the returned code
Response.getWriter (). Print ("Server returned message: successful!\ no (∩ _ ∩) o... !"); / / No problem with returning Chinese
Key points:
Create xmlDom objects in js, and parse in the background. Dom4j is used in the background to parse xml.
