the following code showFeb() will work unless I call showJan() first. the error message I get is “title is null.” I have tried calling getData() again in the function but that didn’t work either.
Any help will be appreciated.
[CODE]function getData(dataSource, divID) {
var mozillaFlag = false;
var XMLHttpRequestObject = false; //create XMLHttpRequest object
if (window.XMLHttpRequest) {
XMLHttpRequestObject = new XMLHttpRequest();
mozillaFlag = true;
}
else if (window.ActiveXObject) {
XMLHttpRequestObject = new
ActiveXObject (“Microsoft.XMLHTTP”);
} // end XMLHttpRequest object
if (XMLHttpRequestObject) { //download the data
var obj = document.getElementById(divID);
XMLHttpRequestObject.open(“GET”, dataSource);
XMLHttpRequestObject.onreadystatechange = function() {
if (XMLHttpRequestObject.readyState == 4 && XMLHttpRequestObject.status == 200) { // got the data
obj = XMLHttpRequestObject.responseXML;
loadNodes(obj); //passes source XML document to displayBusinesses function in variable xmlDocument
}
}
XMLHttpRequestObject.send(null);
}
}
function loadNodes(calObj) {
calendarNode = calObj.getElementsByTagName(“calendar”);
monthNode = calObj.getElementsByTagName(“month”);
eventStartNode = calObj.getElementsByTagName(“eventStart”);
eventEndNode = calObj.getElementsByTagName(“eventEnd”);
eventNameNode = calObj.getElementsByTagName(“eventName”);
locationNode = calObj.getElementsByTagName(“location”);
detailsNode = calObj.getElementsByTagName(“details”);
phoneNode = calObj.getElementsByTagName(“phone”);
webNode = calObj.getElementsByTagName(“web”);
}
function showJan(){
var temp = document.getElementById(“events”);
temp.innerHTML = “sorry no events for Janurary”;
}
function showDetails() {
//get value of each eventName nodes and add link to the details
}
function showFeb() {
var debug = document.getElementById(“eventDetails”);
var counter;
var showEvents = [];
var title = document.getElementById(“eventsTitle”);
title.innerHTML = “February Calendar Events”;
var div = document.getElementById(“eventsBody”);
div.innerHTML = ” “;
for (counter=0; counter < monthNode.length; counter++) {
if (monthNode[counter].firstChild.nodeValue.match(“February”)) {
showEvents = eventNameNode[counter].firstChild.nodeValue;
var newDiv = document.createElement(“div”);
var newText = document.createTextNode(showEvents);
newDiv.appendChild(newText);
div.appendChild(newDiv);
}
//debug.innerHTML = eventNameNode[counter].firstChild.nodeValue;
}
}
