How to hide elements with Jquery if PHP variable is set
I've got this piece of script, and I'm trying to hide two divs (#black and #yname) if a certain variable or session is set in PHP, so is there a simple way to do so? Here's my code:
input.php
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<style type="text/css">
@import "stil.css";
</style>
<title>Untitled Document</title>
<script type="text/javascript" src="jq.js"></script>
<script type="text/javascript" src="jquery-ui-1.8.13.custom.min.js"></script>
<script type="text/javascript" src="scripts.js"></script>
<script type="text/javascript" src="postme.js"></script>
</head>
<body>
<div id="wrap">
<div id="chat">
<div id="main">
</div>
<div id="input">
<form name="form"action="test.php" method="post">
<input type="text" name="tekst" id="msg" size="72" />
<input type="submit" name="dugme" value="posalji" id="dugme" />
</form>
</div>
</div>
</div>
<div id="black">
</div>
<div id="yname">
<form name="yname">
<input type="text" name="tekst2" />
<input type="button" name="dugme2" value="Enter" onclick="send()"/>
</div>
</body>
</html>
postme.js
function send(){
$.post('sesion.php',{name:yname.tekst2.value},function(val){
}
});
}
sesion.php
<?php
session_start();
$data=$_POST['name'];
$_SESSION['name']=$data;
$sesion_n=$_SESSION['name'];
echo $sesion_n;
?>
So basically, what I want to do is to chec开发者_StackOverflowk if $sesion_n variable is set, and if it's set, I want my send() function to hide divs #black and #yname.
In addition, is there a way to use val value with jquery somehow for example to alert it or to assign that value to a javascript variable?
function send(){
$.post('sesion.php',{name:yname.tekst2.value},function(val){
if(val) {
$('#black').hide();
$('#yname').hide();
}
}
});
}
well i didnt get your question completely but you can use hide() method to hide any div in jquery...
