从没有usig jquery的php文件中获取结果

这是一个例子：

function C_xmlObject() {    var xml = null;    try { xml = new ActiveXObject("Microsoft.XMLHTTP"); }    catch(e) { try { xml = new ActiveXObject("MSXML2.XMLHTTP"); }        catch(e) { try { xml = new XMLHttpRequest(); } catch(e) { } } }    return xml;}function C_ajax(daten, url) {    var xml = C_xmlObject();    if(xml !== null) {        xml.open('POST', url, true);        xml.setRequestHeader('Content-type', 'application/x-www-form-urlenpred');        xml.setRequestHeader('Content-length', daten.length);        xml.setRequestHeader('Connection', 'close');        xml.send(daten);        xml.onreadystatechange = function() { if(xml.readyState === 4) {     // Do something }        }    }}

daten例如是“ name = 1＆name2 = Hello”。

编辑：带有原型的版本：

Object.prototype.ajax = function(daten, url, toElement, attributeName) {    var xml = null;    try { xml = new ActiveXObject("Microsoft.XMLHTTP"); }    catch(e) { try { xml = new ActiveXObject("MSXML2.XMLHTTP"); }        catch(e) { try { xml = new XMLHttpRequest(); } catch(e) { } } }    if(xml !== null) {        xml.open('POST', url, true);        xml.setRequestHeader('Content-type', 'application/x-www-form-urlenpred');        xml.setRequestHeader('Content-length', daten.length);        xml.setRequestHeader('Connection', 'close');        xml.send(daten);        if(toElement !== null) { xml.onreadystatechange = function() {     if(xml.readyState === 4) {         if(attributeName === null) {  toElement = xml.responseText;         } else {  toElement[attributeName] = xml.responseText;         }     } }        }    }}

这应该起作用：（{}）。ajax（’value1 =
…’，’index.php’，document.getElementById（’id’），’innerHTML’）;
