XML傳送與接收
Ajax客戶端與伺服端之間，可以使用XML作為資料傳送、溝通的格式，Ajax客戶端若要發送XML，基本上就是將XML作為字串，塞在POST本體中發送，例如：[*]HandleXMLEx-1.js
var xmlHttp;
function createXMLHttpRequest() {
if(window.XMLHttpRequest) {
xmlHttp = new XMLHttpRequest();
}
else if(window.ActiveXObject) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
function prepareXML() {
var xml = "<skills>";
var options = document.getElementById("skills").childNodes;
for(var i = 0; i < options.length; i++) {
var option = options;
if(option.selected) {
xml = xml + "<skill>" + option.value + "<\/skill>";
}
}
xml = xml + "<\/skills>";
return xml;
}
function handleSkills() {
var xml = prepareXML();
var url = "XMLServlet?timeStamp" + new Date().getTime();
createXMLHttpRequest();
xmlHttp.onreadystatechange = handleStateChange;
xmlHttp.open("POST", url);
xmlHttp.setRequestHeader("Content-Type", "text/xml");
xmlHttp.send(xml);
}
<span style="font-family: Courier New,Courier,monospace;">在上例中，將客戶端於多選單中選擇的資料，以下列的XML格式送出：
<div style="margin-left: 40px;"><skills>
<skill>java</skill>
<skill>vb</skill>
<skill>csharp</skill>
</skills>
