I am experiencing an issue where the onchange function is working properly, but the $.post function is not functioning as expected.
Below is the HTML code snippet:
<input type="checkbox" id="chk" value="3" onchange="checkradio(this.value)"/>
Here is the accompanying JavaScript code:
var total=0;
function checkradio(serid) {
var num = 0;
$.post( "getserprice.php",{ serid: serid}, function( data ) {
alert(data);
num = data;
})
if (document.getElementById('chk').checked) {
total = total + num;
} else {
total = total - num;
}
}
This is how the PHP code looks like:
$price = 3;
echo $price;
