I want to add html variables : "<script>var var1 = new CalendarPopup();</script>" according to a number that the user chooses. At the moment I have an ajax setup that is suppose to change my tag to add the variables by changing the inner html like so :
<div id="calVar">
<script>
var cal1 = new CalendarPopup();
var cal2 = new CalendarPopup();
</script>
</div>
function addRespDropDownAjax(currentNumberOfDropDown)
{
//Prepare a new ajaxRequest.
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
//Ajax receiving the response in this function
xmlhttp.onreadystatechange = function()
{
//state 4 is response ready.
//Status 200 is page found.
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById('calVar').innerHTML = '<script>var cal3 = new CalendarPopup();</script>';
alert(document.getElementById('calVar').innerHTML);
}
};
//Send the Ajax request.
xmlhttp.open('GET','mainServlet?command=ajax.AddRespDropDown&NUMBER_OF_DROP_DOWN=' + currentNumberOfDropDown, true);
xmlhttp.send();
}
The last alert :document.getElementById('calVar').innerHTML return nothing and my varaibles are not created. any ideas?
Thanks alot!!
HTML doesn't have variables, and any that are defined in a <script> without deeper nested scope can be simple defined off the window object.
Instead of trying to insert HTML, just use:
window.cal3 = new CalendarPopup();
then any other script can access this variable now or later.

There is a main-feed showing a list of blog post titles. When a title is clicked, I need to display the details of the blog post in a new html file. Below is my current code:
window.location.href = "/viewpost.html";
postID = this.id;
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("view-post-container").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET", "viewpost.php?q=" + postID, true);
xmlhttp.send();
The problem is, the element view-post-container, is in the file viewpost.html, and so I don't think the PHP file can access it. I would just display the data on the current page (index.php), but I wanted to have individual pages for each post so I can eventually learn how to have dynamic URL's for SEO and sharing purposes. The end goal is having dynamic urls, so maybe there is a better approach? Any help would is much appreciated. Thanks.
just try this, You have to put your code in on window.onload function
window.onload = function() {
if (window.XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
} else {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("view-post-container").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET", "viewpost.php?q=" + postID, true);
xmlhttp.send();
}
i have two text box i am trying to pass that textbox value from one page to another page with out page refresh i am using ajax for this but i am able to achive only one text box value
Here is my code
<script>
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", "testing.php?message="+ document.getElementById("message").value+"service="+document.getElementById("city").value, true);
xmlhttp.send();
}
//return false;
</script>
i think i am wrong here in this line
xmlhttp.open("GET", "testing.php?message="+ document.getElementById("message").value+"service="+document.getElementById("city").value, true);
How can i achieve my goal
Any help will be apprecieted
Your query string pairs need to be seperated with an ampersand:
xmlhttp.open("GET", "testing.php?message="+ document.getElementById("message").value+"&service="+document.getElementById("city").value, true);
//Here -----^
After function() it is not working, i don't know why. If I put an alert before that statement it's working but after that statement it isn't working.
<script>
function new_order() {
var xmlhttp;
if (window.XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
}
alert("asdasd");
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("order_id").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("POST", "item_sort.php?sort=" + str, true);
xmlhttp.send();
}
</script>
3 things you can check
If an element corresponding to id order_id exists on the page
if the str is not null or not defined
If you are using older IE versions IE5 or 6 you need to add the
following in your code.
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
Also you need to use the following way if you want to do POST ajax call.
xmlhttp.open("POST", "item_sort.php", true);
xmlhttp.setRequestHeader("Content-type","application/x-www-form-urlencoded");
xmlhttp.send("sort=" + str);
I am new to javascript, am using PHP variable for created link dynamically as given below
$addlink = '<button class="blueBtn btnSmall" id="current'.$product_id.'" onClick=addcart('.#$product_id.',"add")><span class="allitem"
<font color="#A2F3AB">Added</font></span></button>';
This my php variable created by dynamically like below.
Added
Added
Added
I want to change the content of all variable“ added” as“ add” by just one click,Am using ajax function for changing that text as given below..
function clearcart(msg) {
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('cartreturn').innerHTML = xmlhttp.responseText;
document.getElementsByClassName('allitem').innerHTML = "Add";
}
}
xmlhttp.open("GET", "/addcart.php?msg=" + msg, true);
xmlhttp.send();
}
But first link text only affected.. other is not affected how I can solve this problem
document.getElementsByClassName returns a NodeList. You have to iterate over all the elements:
var allItems = getElementsByClassName('allitem');
for (var i = 0; i < allItems.length; i++) {
allItems[i].innerHTML = 'Add';
}
See this question.
You can't do document.getElementsByClassName('allitem').innerHTML.
You can do document.getElementsByClassName('allitem')[0].innerHTML = "Add"
Do you have several elements with the class "allitem"? If you don't, then maybe you should use an id, instead of a class, and then call document.getElementById('allitem').innerHTML = "Add";
I have a url contain all the json format.
http://api.musixmatch.com/ws/1.1/track.lyrics.get?apikey=d34fb59a16877bd1c540aa472491825b&track_id=12414632
function load() {
dashcode.setupParts();
var link = 'http://api.musixmatch.com/ws/1.1/track.search?apikey=d34fb59a16877bd1c540aa472491825b&q_track=back%20to%20december&page_size=10';
req.open = ("GET", link, false);
req.onreadystatechange = readXML();
req.send(null);
}
function readXML(){
alert(req.responseText);
}
this code keep saying null all the time.
Are there any way that i can retrieved those json text
The problem is with req.onreadystatechange = readXML();. You're assigning the result of the function instead of the function itself (as a callback).
You want req.onreadystatechange = readXML;. Though I must say I'm not sure how this code is supposed to work. Not in terms of how the XHR is made, nor with regards to the external domain.
Correct usage is as follows.You can check this link http://jsfiddle.net/UH4KY/1/ The link will alert undefined since cross domain scripting is not allowed .You can set the Access-Control-Allow-Origin and test the code.
function readXML(req) {
alert(req);
}
function load() {
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");
}
var link = 'http://api.musixmatch.com/ws/1.1/track.search?apikey=d34fb59a16877bd1c540aa472491825b&q_track=back%20to%20december&page_size=10';
//req.open = ("GET", link, false);
xmlhttp.onreadystatechange = function(){ alert(xmlhttp.responseText); }
xmlhttp.open("GET", link, false);
xmlhttp.send(null);
}
