JS实现POST.docx

function posthtm(url,id,verbs,is)var doc = document.getElementById(id);doc.innerHTML=Loading.;var xmlhttp = false;if(doc!=null)doc.style.visibility=visible;if(doc.style.visibility=visible)xmlhttp=ajax_driv();xmlhttp.open(POST, url,true);xmlhttp.onreadystatechange=function() if (xmlhttp.readyState=4) if (is)doc.innerHTML=xmlhttp.responseText;elseeval(xmlhttp.responseText);xmlhttp.setRequestHeader(Content-Length,verbs.length);xmlhttp.setRequestHeader(CONTENT-TYPE,application/x-www-form-urlencoded);xmlhttp.send(verbs);微软的JavaScript,Post的实例（XMLHTTP） 下面这个functioon是我分析MSN的一个网址截取的，对使用javascript Post数据的时候有用，以前我都是用笨办法在页面上放个隐藏的form然后submit，现在可以直接用使用post了，_！function_sd_Post(Url,Args) varxmlhttp; varerror; eval(tryxmlhttp=newActiveXObject(Microsoft.XMLHTTP);catch(e)xmlhttp=null;error=e;); if(null!=xmlhttp) xmlhttp.Open(POST,Url,false); xmlhttp.setRequestHeader(Content-Type,application/x-www-form-urlencoded); xmlhttp.Send(Args); strText=xmlhttp.responseText; /ifourresponsestartswithhttpthanredirectthere if(strText!=null&strText.toLowerCase().indexOf(http)=0) location.href=strText; else location.href=c_errorUrl; returnstrText; functionGetActionUrl(listKey) returndocument.getElementById(ActionUrl:+listKey).url 靠！下面是从Google搜索到的更有用的，哈哈！/Web/Web_Languages/Q_21132871.html SolutionTitle:Microsoft.XMLHTTPsendingafile askedbymikevandikeon09/15/200404:21PMPDT HiIamcurrentlyre-developingawebbasedfrontendforanestateagenttomanagetheirpropertys.IhavedecidedtouseaMicrosoft.XMLHTTPobjecttocommunicatebetweentheclientandserver.Myproblemisgottodowithsendingafilewiththis.TheclientiscomposedoftheusualGUIcomponentswhichthedatacanbeeasilyretrievedfromforsendingtotheserverbutitalsocontainsafileelementforselectingapictureofthepropertytobeuploaded.HowdoIgetthedatafromthissothatitcanbeuploadedtotheserverusingtheMicrosoft.XMLHTTPobject.IhavefoundabitofcodeonthenetbutitisnousetomebecauseitwouldinvolvechangingthesecurityinInternetOptionswhichIhavenocontrolover.

This property changes as the document is being loaded. responseText How to return the request as a string. status How to return the status of the operation, as a code. statusText How to return the status of the operation, as a string. The HttpRequest objectWith the httpRequest object you can send a request from the client to the server.If you are using JavaScript in IE 5.0, you can create the HttpRequest object with the following code:var xmlHTTP = new ActiveXObject(Microsoft.XMLHTTP)If you are using VBScript you create the httpRequest object with the following code:set xmlHTTP = CreateObject(Microsoft.XMLHTTP)The httpRequest object is not a part of the W3C DOM standard.Get XMLHow to get an xml file from the server using the httpRequest object (works only in IE):var xmlHttp = new ActiveXObject(Microsoft.XMLHTTP)xmlHttp.open(GET, note.xml, false)xmlHttp.send()xmlDoc=xmlHttp.responseTextTry it Yourself Netscape compatible code: xmlHttp = new XMLHttpRequest();xmlHttp.open(GET, note.xml, false);xmlHttp.send(null);xmlDoc = xmlHttp.responseText;Try it Yourself Send XMLYou can also send an xml document to an ASP page on the server, analyze the request, and send back the result.var xmlHttp = new ActiveXObject(Microsoft.XMLHTTP)xmlHttp.open(POST, demo_dom_http.asp, false)xmlHttp.send(xmlDoc)document.write(xmlHttp.responseText)The ASP page, written in VBScript:set xmldoc = Server.CreateObject(Microsoft.XMLDOM)xmldoc.async=falsexmldoc.load(request)for each x in xmldoc.documentElement.childNodes if x.NodeName = to then name=x.textnextresponse.write(name)You send the result back to the client using the response.write property.Try it Yourself Important NoteAt the moment, the Microsoft XMLHTTP object can only be run in the BROWSER.SERVER code that attempts to use the XMLHTTP to communicate with other Web servers, may function incorrectly or perform poorly.This is a bug in the HTTPRequest object. For more information read Microsofts Knowledge Base article Q237906. The rumor is that Microsoft will have this bug fixed in an upcoming release of the XML Library. In the meantime, you may have to use a commercially available ASPHTTP component.The httpRequest PropertiesProperty Description readyStateReturns the state of the documentresponseBodyReturns the response as an array of unsigned bytesresponseStreamReturns the response a
