javascript not setting innerHTML
I'm working on a website for a client and I am using ajax to get the contents of a file, html specifically, and then I am trying to insert that html into a div so that i can display the content. i know that i am getting the contents of the file because i have alerts set to display the request's readyState, status, and responseText, and it is showing the contents of the file in the alert. however when i attmept to insert it into the div using this line: document.getElementsByClassName('content').innerHTML = response; nothing happens. can anyone help me figure this out?
CODE:
JAVASCRIPT:
<script language="javascript" type="text/javascript">
var request = new ajaxRequest();
var fileLoc;
var response;
function getData(fileName){
fileLoc = encodeURI("assets/"+fileName+".html")
alert(fileLoc);
request.onreadystatechange = processData;
request.open("GET",fileLoc, false);
request.send();
alert(request.readyState);
alert(response);
alert(request.status);
document.getElementsByClassName('content').innerHTML = response;
}
function processData(){
response = request.responseText;
/*if (request.readyState==4){
if (request.status==200){
try{
document.getElementsByClassName('content').innerHTML = response;
} catch(e){
alert("Error: " +e.description);
}
}
else{
alert("An error has occured making the request");
}
}*/
}
function home() {
getData("home");
}
function about() {
getData('about');
}
function proof() {
getData('contact');
}
function contact() {
getData('proof');
}
function ajaxRequest(){
var activexmodes=["Msxml2.XMLHTTP", "Microsoft.XMLHTTP"]
if (window.XMLHttpRequest)
return new XMLHttpRequest();
else if (window.ActiveXObject){
for (var i=0; i<activexmodes.length; i++){
try{
return new ActiveXObject(activexmodes[i]);
}
catch(e){
alert(e.description);
}
}
}
else
return false
}

document.getElementByClassName is returning an array. You cannot set the innerHtml of an array you need to loop through the array and set each individual elements inner html;
Working example: http://jsfiddle.net/CYZUL/
function processData(){
response = request.responseText;
/*if (request.readyState==4){
if (request.status==200){
try{
var elements = document.getElementsByClassName('content');
for(var x=0; x < elements.length; x++)
{
elements[x].innerHTML = response;
}
} catch(e){
alert("Error: " +e.description);
}
}
else{
alert("An error has occured making the request");
}
}*/
}
function getData(fileName){
fileLoc = encodeURI("assets/"+fileName+".html")
alert(fileLoc);
request.onreadystatechange = processData;
request.open("GET",fileLoc, false);
request.send();
alert(request.readyState);
alert(response);
alert(request.status);
var elements = document.getElementsByClassName('content');
for(var x=0; x < elements.length; x++)
{
elements[x].innerHTML = response;
}
}
Why not using the jQuery's $.load(); function and save your self a lot of pain and time
加载中,请稍侯......
