Apologies if this question has already been asked, I tried searching but couldn't find any answers (OR didn't understand the answer).
I have a hyperlink and would like to retrieve the value using AJAX. Here is an example with PHP:
HOME
<a href="page.php?value=3">Go</a>PAGE
$getValue = $_GET['value'];
echo $getValue;
Thank you!
Utilize the $.get() function for performing an ajax get request.
jQuery
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('a[href="page.php?value=3"]').click(function(e){
e.preventDefault()
$.get("page.php",{value:3},function(data){
alert(data);
});
});
});
</script>
<a href="page.php?value=3">Go</a>
page.php
<?php
$getValue = $_GET['value'];
echo $getValue;
?>
$(document).ready(function(){ }) handler to ensure it runs after the DOM elements are loaded.preventDefault() method to prevent the default browser action on the event.click() method to listen for click events.$.get() method for making Ajax get requests. Using pure Javascript:
<script type="text/javascript">
function fetchXML() {
var xmlReq;
if (window.XMLHttpRequest) {
// code for modern browsers
xmlReq = new XMLHttpRequest();
} else {
// code for old IE versions
xmlReq = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlReq.onreadystatechange = function() {
if (xmlReq.readyState == 4 && xmlReq.status == 200) {
// insert the response in your HTML element
document.getElementById("myDiv").innerHTML = xmlReq.responseText;
}
}
xmlReq.open("GET", "page.php?value=3", true);
xmlReq.send();
}
</script>
Using jQuery:
$.ajax({
url: "page.php",
data: { value: 3 },
context: document.body,
success: function(){
$(this).addClass("done");
}
});
In jQuery, the default method used is GET, but it can be changed. For more information on jQuery methods, visit https://api.jquery.com/jQuery.ajax/
Utilize jQuery ajax for this task
$.ajax({
type: "POST",
url: "data.php",
data: { number: 5}
});
data.php
<?php
$numberValue = $_POST['number'];
echo $numberValue;
?>
