<head>
<script src="jquery-1.7.2.js" type="text/javascript"></script>
<script src="js.js" type="text/javascript"></script>
</head>
<body>
<p> click </p>
<input type="text" id="who">
<br>
<input type="text" id="why">
<div id="bg" align="center">
</div>
</body>
this is my JS file
$(document).ready(function(){
$('p').click(function(){
var who = $('input#who').val();
var why = $('input#why').val();
$.post('file.php',{who:who,why:why},function(data) {
if(data.success){
alert(data.message);
}
else{ alert('ERROR:' + data.message);
}
});
});

2- how i can get some result from that php file when its have other output
like this:
<?php
echo "1";
echo "2";
echo "3";
and now echo that json

thanks 🙁
You have to tell jQuery that the response is JSON. You can do so by either passing
'json'as forth parameter to$.post[docs] or by setting the correct response headers in PHP:Alternatively you can parse the response yourself with
jQuery.parseJSON[docs].There is no easy way. The response is not valid JSON anymore, so you have to parse it yourself somehow. You should avoid doing this and return everything as JSON.
