Repeat function

Hello how are you?
I need to repeat this code 100 times. If you look only changes "showuser []" and "cargarproducto []". As I can do to not have to write it 100 times?
Someone can help me? thank you very much
function showUser1(str){
if (str==""){
document.getElementById("cargarproducto1").innerHTML="";
return;
}
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("cargarproducto1").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","catalog/model/catalog/obtendatos.php?q="+str,true);
xmlhttp.send();
}
function showUser2(str){
if (str==""){
document.getElementById("cargarproducto2").innerHTML="";
return;
}
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("cargarproducto2").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","catalog/model/catalog/obtendatos.php?q="+str,true);
xmlhttp.send();
}
function showUser3(str){
if (str==""){
document.getElementById("cargarproducto3").innerHTML="";
return;
}
if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("cargarproducto3").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","catalog/model/catalog/obtendatos.php?q="+str,true);
xmlhttp.send();
}

You can write generic function pass URL, Parameters and destination div ID to it.
function makeRequest(url, str, div_id) {
if (str==""){
document.getElementById(div_id).innerHTML="";
return;
}
http_request = false;
if (window.XMLHttpRequest) { // Mozilla, Safari,...
http_request = new XMLHttpRequest();
if (http_request.overrideMimeType) {
// set type accordingly to anticipated content type
http_request.overrideMimeType('text/xml');
// http_request.overrideMimeType('text/html');
}
} else if (window.ActiveXObject) { // IE
try {
http_request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
http_request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
}
}
}
if (!http_request) {
alert('Your browser does not support AJAX!');
return false;
}
http_request.onreadystatechange = function(){
if (http_request.readyState==4 && http_request.status==200){
document.getElementById(div_id).innerHTML=http_request.responseText;
}
http_request.open('GET', url + str, true);
http_request.send(null);
}

Reusing ajax function

I want to reuse this function but I want to change the id everytime (in this case brand), do I have to make the function all over again each time or is there another way?
This is the function:
function showUser(str)
{
if (str=="")
{
document.getElementById("brand").innerHTML="";
return;
}
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("brand").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","inc/form_rest.php?q="+str,true);
xmlhttp.send();
}

Pass in the id as a parameter of the function?

You can pass the id as parameter...
function showUser(str, id) {
if (str=="") {
document.getElementById(id).innerHTML="";
return;
}
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
} else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function() {
if (xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById(id).innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","inc/form_rest.php?q="+str,true);
xmlhttp.send();
}

Display all nodes inside a tagname with JavaScript

I'm trying to use the loadXMLDoc() JavaScript function to load data from an XML document and show it on my page's DIV when a button is clicked. So far I can't get any content in my DIV, I want to load all elements within an specific tagname.
Here's the XML:
<?xml version="1.0" encoding="UTF-8"?>
<Fruits>
<Cell>Apples</Cell>
<Cell>Bananas</Cell>
<Cell>Strawberries</Cell>
</Fruits>
<Vegetables>
<Cell>Lettuce</Cell>
<Cell>Tomatoes</Cell>
<Cell>Carrots</Cell>
</Vegetables>
Here's the JavaScript:
function fruits()
{
var
xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
xmlDoc = xmlhttp.responseXML;
document.getElementById("food").innerHTML=xmlDoc.getElementsByTagName("fruits");
}
xmlhttp.open("GET","document.xml", true);
xmlhttp.send();
}
function vegetables()
{
var
xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
xmlDoc = xmlhttp.responseXML;
document.getElementById("food").innerHTML=xmlDoc.getElementsByTagName("vegetables");
}
xmlhttp.open("GET","document.xml", true);
xmlhttp.send();
}
And here's the HTML:
<button type="button" onclick="fruits()">Fruits</button>
<button type="button" onclick="vegetables()">Vegetables</button>
<div id="food">Please select your favorite</div>

Your function fruits() is not closed properly, and your function vegetables() has ended up inside function fruits(),
the same goes for defining the function xmlhttp.onreadystatechange=function()
so these functions will not even be available until fruits() is called.
Your code should look like this:
function fruits()
{
var
xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
xmlDoc = xmlhttp.responseXML;
document.getElementById("food").innerHTML=xmlDoc.getElementsByTagName("fruits");
}
}
//something went wrong here : this code ended up in the function that was to be called when xmlhttp was done with its GET operation.
//consequently it was never called
xmlhttp.open("GET","document.xml", true);
xmlhttp.send();
} // <-- this here bracket was missing
function vegetables()
{
var
xmlhttp;
if (window.XMLHttpRequest)
{
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{
// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
xmlDoc = xmlhttp.responseXML;
document.getElementById("food").innerHTML=xmlDoc.getElementsByTagName("vegetables");
}
}
//the same thing happened here
xmlhttp.open("GET","document.xml", true);
xmlhttp.send();
}

ajax show 2 data request with onclick

hello i am still new on ajax i wanted show 2 data in different place.
here the code
<li onclick="showPost(this.value);" value="*digit*" >lala</li>
the javascript
<script>
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
function showPost(hal)
{
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("gallekanan").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","../wp-content/themes/koolfort/example.php?pal="+hal,true);
xmlhttp.send();
showJudul(hal);
}
function showJudul(hal)
{
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("eventjudul").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","../wp-content/themes/koolfort/example1.php?pal="+hal,true);
xmlhttp.send();
}
</script>
when i running the code just the showJudul running and the showPost is Aborted.

Move showJudul(hal); just after document.getElementById("gallekanan").innerHTML=xmlhttp.responseText;

Try having individual control of each function rather than calling them one within another one.. ie.. have it as
<li onclick="showPost(this.value); showJudul(this.value);" value="*digit*" >lala</li>
and
<script>
function showPost(hal)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("gallekanan").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","../wp-content/themes/koolfort/example.php?pal="+hal,true);
xmlhttp.send();
}
function showJudul(hal)
{
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("eventjudul").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","../wp-content/themes/koolfort/example1.php?pal="+hal,true);
xmlhttp.send();
}
</script>
Also try using try{}catch{} where you try to initialize xmlhttp - the function might give error if there is no such object available...

How do you make this ajax example work on opera and firefox?

I have a quick question, the following only works on IE 7 and above, how can I make it work on firefox and opera aswell?
<html>
<head>
<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","http://www.tdsoft.se/index.html",true);
xmlhttp.send();
}
</script>
</head>
<body>
<div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadXMLDoc()">Change Content</button>
</body>
</html>
Edit
Thanks for all your answers, now I just have another question regarding the followng code
<html>
<head>
<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
return xmlhttp.responseText;
}
}
xmlhttp.open("GET","index.html",true);
xmlhttp.send();
}
</script>
</head>
<body>
<div id="myDiv"><h2>Let AJAX change this text</h2></div>
<button type="button" onclick="loadXMLDoc()">Change Content</button>
</body>
</html>
Now I want to search through the xmlhttp.responseText (in other words call the function loadXMLDoc()) for key words, like for example "testfile" and if it exists multiple example "testfile_1" and "testfile_2"....."testfile_n" then "doSomething"
like this
function searchADocument(wordToSearchFor){
int numberOfTimesWordOccurs=0;
var thePageToSearchThrough [] = loadXMLDoc();
for (i=0; i<thePageToSearchThrough.length; i++){
if(thePageToSearchThrough[i]==wordToSearchFor)
numberOfTimesWordOccurs++;
}
If (wordToSearchFor > 1)
document.write(" testfile_1" testfile_2 testfile_n
)
Else
window.location="http://selnc05.go.se:8080/component_test/build/testfile.html";
}
I don't know where to start since I don't know what type xmlhttp.responseText is, can I store it in an array and scan it using for loop etc?
Thanks in advance. =)

Try something like this:
ajax("http://www.tdsoft.se/index.html", function(data) {
document.getElementById("myDiv").innerHTML = data;
});
Code
function getXmlHttpObject() {
var xmlHttp;
try {
xmlHttp = new XMLHttpRequest();
} catch (e) {
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
}
}
return xmlHttp;
}
function ajax(url, onSuccess, onError) {
var xmlHttp = getXmlHttpObject();
xmlHttp.onreadystatechange = function () {
if (this.readyState == 4) {
if (this.status != 200) {
if (typeof onError == 'function') {
onError(this.responseText);
}
}
else if (typeof onSuccess == 'function') {
onSuccess(this.responseText);
}
}
};
xmlHttp.open("GET", url, true);
xmlHttp.send(null);
return xmlHttp;
}​
