I am trying to highlight a table row using Jquery’s .hover() method.
I have the following code:
var x;
var namen;
window.onload = function(){
x = true;
y = true;
$("submitnieuw").observe('click', addturf);
$("submitdelete").observe('click', verwijderturf);
$("stats").on("click", "tr", select);
setInterval(function (){
jQuery("#recent").load("vandaag.php");
if(x){
jQuery("#stats").load("stats.php");
}
}, 10000);
$("tr").not(':first').hover(
function () {
$(this).addClassName("selected");
},
function () {
$(this).removeClassName("selected");
}
);
alert("test");
};
function select(naam){
//highlight the selected list element
if (y){
var name = naam.findElement('tr').id;
if (name !== ""){
x = false;
y = false;
jQuery.ajax('details.php',{
data: {
'Naam': name,
'door': $("door2").value
},
type: 'post',
success: function(data){
$("stats").innerHTML = data;
},
error: ajaxFailure
});
}
}
else{
x = true;
y = true;
jQuery("#stats").load("stats.php");
jQuery("#recent").load("vandaag.php");
}
}
function verwijderturf() {
var box = document.getElementById("naamverwijder");
var naam = box.options[box.selectedIndex].value;
document.getElementById("naamnieuw").selectedIndex=0;
$("redennieuw").value = "";
jQuery.ajax('server.php',{
data: {
'mode': 'verwijderturf',
'naam': naam,
'door': $("door2").value
},
type: 'post',
success: update,
error: ajaxFailure
});
}
function addturf() {
var box = document.getElementById("naamnieuw");
var naam = box.options[box.selectedIndex].value;
document.getElementById("naamnieuw").selectedIndex=0;
var reden = $("redennieuw").value;
$("redennieuw").value = "";
jQuery.ajax('server.php',{
data: {
'mode': 'addturf',
'naam': naam,
'door': $("door2").value,
'reden': reden
},
type: 'post',
success: update,
error: ajaxFailure
});
}
function update(ajax){
jQuery("#stats").load("stats.php");
jQuery("#recent").load("vandaag.php");
}
function ajaxFailure(ajax, exception) {
alert("Error making Ajax request:" +
"\n\nServer status:\n" + ajax.status + " " + ajax.statusText +
"\n\nServer response text:\n" + ajax.responseText);
if (exception) {
throw exception;
}
}
selected is defined in the css I have included in my index.php.
This is my index.php
<?php
include_once("db.php");
session_start();
if (!isset($_SESSION['uid'])){
header("location:main_login.php");
exit();
}
if (!isset($_SESSION['upass'])){
header("location:main_login.php");
exit();
}
$sql="SELECT * FROM users WHERE Naam='".$_SESSION['uid']."' AND Wachtwoord='".$_SESSION['upass']."'";
$result=mysql_query($sql);
$count=mysql_num_rows($result);
if($count < 1){
header("location:main_login.php");
exit();
}
?>
<?php
$date = date("y-m-d");
$vandaag = mysql_query("SELECT Type, Naam, Reden, Door FROM turfjes WHERE turfjes.Datum = '" . $date . "'");
$names = mysql_query("SELECT Naam From users");
$names2 = mysql_query("SELECT Naam From users");
$names3 = mysql_query("SELECT Naam From users");
?>

The test alert is not executed so I know that my hover is not working. I checked and everything before the hover is executed however and still functional.
I am not quite sure what I am doing wrong.
Can anybody help me please?
My syntax seems to be just fine, according to online checkers.
It seems (not sure due to your code being php) that you want to apply hover on elements that aren’t present on load. If that’s the case, you cannot simply do
You must use jquery on so that it will be applied to all elements appearing.
To replace a hover by a on, you have to hook the ‘mousenter’ and ‘mouseleave’ events :
