Question

下面的脚本在IE中完美地用于XML响应。但似乎我无法弄清楚如何在Firefox或Chorme上运行。尝试一些修改，但仍然无法运行它。请需要助手。

<script type="text/javascript" language="javascript"> 
var xmlhttp;
var timeStamp;

var currentTime = new Date()
var month = currentTime.getMonth() + 1
var day = currentTime.getDate() //remove the + 1  afterwards
var year = currentTime.getFullYear()
var hour = currentTime.getHours()
var minutes = currentTime.getMinutes()
var second = currentTime.getSeconds() + 1


timeStamp = day + "/" + month + "/" + year + " " + hour + ":" + minutes + ":" + second;



function on_click()

{



    var xmlToSend = "<?xml version='1.0' encoding='utf-8'?>";
    xmlToSend += "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' ";
    xmlToSend += "xmlns:xsd='http://www.w3.org/2001/XMLSchema' ";
    xmlToSend += "xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'>";
    xmlToSend += "<soap:Body><Welcomescreen Sender='SENDERDDRESS' TimeStamp='28/10/2009 16:49:31' Type='1' Workshop='SG' RequireAppointmentDate='2010/01/04' xmlns='http://www.SENDERDDRESS.com/integration'/>";
    xmlToSend += "</soap:Body></soap:Envelope>";

    /


    var xmldoc = new ActiveXObject("Microsoft.XMLDOM"); 
    xmldoc.loadXML(xmlToSend); 


    if (window.XMLHttpRequest)
      {/ / code
    for IE7 + , Firefox, Chrome, Opera, Safari
    xmlhttp = new XMLHttpRequest();
} else { // code for IE6, IE5
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

xmlhttp.onreadystatechange = state_Change;

xmlhttp.open("POST", "http://SENDERDDRESS:4509/resd", false);

var objResponse = document.getElementsByTagName("Appointment");

objResponse.innerText = xmlhttp.responseXML.xml;

我看到两个问题。一个是你在一系列/行之后有一个迷路xmlToSend +=，这是一个语法错误，然后就是这样：

var xmldoc = new ActiveXObject("Microsoft.XMLDOM");

ActiveXObject不是标准的，它是IE特定的东西。与您使用它的其他地方不同，该行不是有条件的。

您只需将xmlToSend字符串直接传递到XMLHttpRequest#send（link），您就不需要首先制作XML文档。它只需要再次转回一个字符串即可发送。

如果您确实想要实际创建XML文档对象，则可以在兼容的浏览器上使用DOMImplementation#createDocument（例如document.implementation.createDocument）。

偏离主题：JavaScript库可以让您在Ajax领域（以及许多其他领域）的生活更轻松。像jQuery，Closure，Prototype，YUI或any of several others之类的内容可能会为您节省一些时间。

新的XMLHttpRequest无法在Firefox上运行
