Pass the data to send in parameter/value pairs like this: "value=100". postDataReturnXml(urlToCall, dataToSend, functionToCallBack) Uses the POST method to send dataToSend to server, gets XML back. Pass the data to send in parameter/value pairs like this: "value=100". */ function getText(urlToCall, functionToCallBack) { var XMLHttpRequestObject = false; if (window.XMLHttpRequest) { XMLHttpRequestObject = new XMLHttpRequest(); } else if (window.ActiveXObject) { XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP"); } if(XMLHttpRequestObject) { XMLHttpRequestObject.open("GET", urlToCall); XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { functionToCallBack(XMLHttpRequestObject.responseText); delete XMLHttpRequestObject; XMLHttpRequestObject = null; } } XMLHttpRequestObject.send(null); } } function getXml(urlToCall, functionToCallBack) { var XMLHttpRequestObject = false; if (window.XMLHttpRequest) { XMLHttpRequestObject = new XMLHttpRequest(); XMLHttpRequestObject.overrideMimeType("text/xml"); } else if (window.ActiveXObject) { XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP"); } if(XMLHttpRequestObject) { XMLHttpRequestObject.open("GET", urlToCall); XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { functionToCallBack(XMLHttpRequestObject.responseXML); delete XMLHttpRequestObject; XMLHttpRequestObject = null; } } XMLHttpRequestObject.send(null); } } function postDataGetText(urlToCall, dataToSend, functionToCallBack) { var XMLHttpRequestObject = false; if (window.XMLHttpRequest) { XMLHttpRequestObject = new XMLHttpRequest(); } else if (window.ActiveXObject) { XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP"); } if(XMLHttpRequestObject) { XMLHttpRequestObject.open("POST", urlToCall); XMLHttpRequestObject.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { functionToCallBack(XMLHttpRequestObject.responseText); delete XMLHttpRequestObject; XMLHttpRequestObject = null; } } XMLHttpRequestObject.send(dataToSend); } } function postDataGetXml(urlToCall, dataToSend, functionToCallBack) { var XMLHttpRequestObject = false; if (window.XMLHttpRequest) { XMLHttpRequestObject = new XMLHttpRequest(); XMLHttpRequestObject.overrideMimeType("text/xml"); } else if (window.ActiveXObject) { XMLHttpRequestObject = new ActiveXObject("Microsoft.XMLHTTP"); } if(XMLHttpRequestObject) { XMLHttpRequestObject.open("POST", urlToCall); XMLHttpRequestObject.setRequestHeader('Content-Type', 'application/x-www-form-urlencoded'); XMLHttpRequestObject.onreadystatechange = function() { if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { functionToCallBack(XMLHttpRequestObject.responseXML); delete XMLHttpRequestObject; XMLHttpRequestObject = null; } } XMLHttpRequestObject.send(dataToSend); } }
