I have a page containing a list of events, generated by a DB query, that the user can, for each event, click a button to register for the event. This fires a registration form (contained on event-registration.php) which is displayed via AJAX Magnific popup.
On normal pageload, the popup fires as expected as an AJAX type with the form embedded within the popup.
<a href='event-registration.php?eid=".$myrow['EID']."' class='ajax-popup-link' title='".$myrow['Tooltip']."' ><button type='button' class='".$myrow['StatusCSS']." buttonWrap'>".$myrow['StatusName']."</button></a>
$(document).ready(function() {
$('.ajax-popup-link').magnificPopup({
type: 'ajax',
cursor: 'mfp-ajax-cur',
closeOnContentClick: false
});
});
However, the results also have a couple of filters that can be applied, based on type of event, location etc. These are handled by XMLHTTP requests to dynamically filter the search results without having to reload the whole page.
<select id="EventLocation" onchange="filterEventsLocation(this.value)" class="filter">
<option value="">Filter by Event Location</option>
<option value="1">Scotland</option>
<option value="2">North of England</option>
<option value="3">Midlands</option>
<option value='4'>London & South East</option>
<option value='5'>South West</option>
<option value="reset">Reset (Show All)</option>
</select>
function filterEventsLocation(str) {
if (str == "" || str == "reset") {
document.getElementById("EventsList").innerHTML = xmlhttp.responseText;
xmlhttp.open("GET", "prt.getEvents.php", true);
xmlhttp.send();
/*document.getElementById("EventsList").innerHTML = "";
return;*/
} else {
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("EventsList").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET","prt.getEvents.php?l="+str,true);
xmlhttp.send();
}
prt.getEvents.php contains the SQL query code as well as a div 'EventsList' which then displays the query results.
However, once a filter is applied, the popup box no longer works, instead when the user clicks the button they're just taken straight to the event-registration.php file with no sign of magnific popup at all.
Does anyone have any ideas why the popup isn't initialising once the filter has been applied to the list of events?
UPDATED JAVASCRIPT ADDING EVENT LISTENER:
function filterEventsType(str) {
if (str == "" || str == "reset") {
document.getElementById("EventsList").innerHTML = xmlhttp.responseText;
xmlhttp.open("GET", "prt.getEvents.php", true);
xmlhttp.send();
/*document.getElementById("EventsList").innerHTML = "";
return;*/
} else {
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("EventsList").innerHTML = xmlhttp.responseText;
document.getElementById("RegisterBox").addEventListener("onclick", openPopup);
function openPopup() {
$('.open-popup-link').magnificPopup({
type: 'inline',
midClick: true })
}
}
};
xmlhttp.open("GET","prt.getEvents.php?t="+str,true);
xmlhttp.send();
}
}

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();
}
When I view my sample.php page, I only see my combo box, and when I start to select a value from my combo box, that's when my data from database show which is from my getyear.php.
What I want to do is the moment I view that page with the default value which is, for instance, 2014-2016, I can already see the data from my getyear.php
This is what I have in my javascript:
/* event handler ~ no ajax function shown */
function showofficers(str){
if (str == "") {
document.getElementById("txtHint").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("txtHint").innerHTML = xmlhttp.responseText;
}
};
xmlhttp.open("GET","getyear.php?q="+str,true);
xmlhttp.send();
}
$(document).ready(function(){
var year = document.getElementById("year").value;
if (year =="") {
document.getElementById("txtHint").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("txtHint").innerHTML=xmlhttp.responseText;
}
}
mlhttp.open("GET","get_year.php?q="+year,true);
xmlhttp.send();
});
My div is:
<div id="txtHint"></div>
Just continue with:
if (year =="") {
document.getElementById("txtHint").innerHTML="";
return;
} else {
showofficers(year);
};
and make sure the function showofficers is in context.
I want a search box which shows the result just below it when I click the search button without reloading the page.
for this I've js function called ShowUsers(str)
like this
function showUser(str) {
if (str == "") {
document.getElementById("txtHint").innerHTML = "";
return;
} else {
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("txtHint").innerHTML =
xmlhttp.responseText;
}
}
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
}
And a html form like this :
<form>
<input type="text" name="q"/>
<script type="text/javascript">var x = document.getElementById("q").value; </script>
<input type="button" value="search" onclick="showUser(x)">
</form>
<br>
<div id="txtHint"><b>Person info will be listed here...</b></div>
I've one php file to show the result called as GetUser.php
I think the var x deos'nt pass to the ShowUser(str) function in the input tag I think this is not a right way to pass a js var into html event
so what can i do to show the data
Access document.getElementById("q").value directly in showUser function rather than passing x to showUser function.
function showUser() {
var str = document.getElementById("txtHint").value;
if (str == "") {
document.getElementById("txtHint").innerHTML = "";
return;
} else {
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("txtHint").innerHTML =
xmlhttp.responseText;
}
}
xmlhttp.open("GET","getuser.php?q="+str,true);
xmlhttp.send();
}
}
Can anyone tell me why I can't get the elements from an XML document? It doesn't print anything when I press the et Title button that i have implemented in the body section. Here's my code:
function MyF () {
var xmlhttp;
var txt,x,i=0;
var xx;
if (window.XMLHttpRequest){
xmlhttp=new XMLHttpRequest();
}
else{
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.send();
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
x = xmlhttp.responseXML.documentElement.getElementsByTagName("CD");
xx = x[i].getElementsByTagName("TITLE");
document.getElementById("test").innerHTML=xx;
}
}
xmlhttp.open("GET","cd_catalog.xml",true);
}
xmlhttp.responseXML.documentElement is the problem of your troubles. Just use xmlhttp.responseXML.getElementsByTagName and you should be fine.
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

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);
