Syntax: AJAXCALL (url,handleResponse,param); give the callback data to handleResponse for processing

Example 1:

AJAXCALL ("gaogao.xml", "doPostXml", "method=POST, isXML=true, isCache=true,attach=showContent")

Function doPostXml (doc,id) {

Alert (doc) / / get the returned XML document

Alert (id) / / extension parameter, the value of attach, "showContent"

If (doc) {

$(id) = getTagValue (doc,retcode)

}

}

Example 2:

AJAXCALLl ("getnews?pid=23412", "shownews", "attach=" + $('yoyo'))

Function shownews (docu,divObject) {

If (docu) {

DivObject.innerHTML=docu

} else {

DivObject.innerHTML= "system error"

}

}

Note:

If POST data, encode the data and add it to the URL, for example:

AJAXCALL ("gaogao.php?name=" + $U ('yo') + "& sex=" + male, "yoyo2", "method=POST")
