I am working on live notification script.
I have managed to rend request to external file, but the script returns random hash instead of plain text...
This is my function that should get data from test.php
<script>
$(document).ready(function () {
function load() {
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "/test.php",
dataType: "html", //expect html to be returned
success: function (response) {
$("#responsecontainer").append(response);
setTimeout(load, 5000)
}
});
}
load(); //if you don't want the click
// $("#display").click(load); //if you want to start the display on click
});
</script>
And it should append to the results.
This is the source of test.php
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Headerview</title>
</head>
<body>
<?php
$p = "<p>test</p>";
echo $p;
?>
</body>
</html>
And this is what I am getting...

The file path was the problem. I did not specify exact file path.
Thank you

I have a JS script that scrapes a bit of data and outputs the result to the screen. That works fine. What I now need to do is wrap that output in some pre and post content php files for formatting purposes, and I can't seem to get it to work.
Here's where the script stands now:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<meta content="width=device-width; initial-scale=1.0; maximum-scale=1.0; user-scalable=0;" name="viewport">
<script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
<link rel="stylesheet" type="text/css" href="css/main.css">
</head>
<body>
<img id="loading-gif">
<script>
$('#loading-gif').hide();
$(document).ready(function () {
$('#loading-gif').show();
$.ajax({
url: "https://aajumpseat.com/dev/include/pre.content.php'); ?>",
type: 'GET',
dataType:"json",
success: function(data) {
pre = JSON.parse(data);
document.write(pre);
}
});
$.ajax({url: "https://aajumpseat.com/dev/scrape/getSegments.php"}).done(function (data) {
$('#loading-gif').hide();
output = JSON.parse(data);
document.write(output);
});
$.ajax({
url: "https://aajumpseat.com/dev/include/post.content.php'); ?>",
type: 'GET',
dataType:"json",
success: function(data) {
post = JSON.parse(data);
document.write(post);
}
});
});
</script>
</body>
</html>
The second ajax call works perfectly and outputs the result to the screen, which is what I want. What I would like to do is place the contents of pre.content.php before the result and the contents of post.content.php after the result so that the result is properly formatted.
There is some php being executed in 'pre.content.php is addition to the formatting html, while 'post.content.php contains only the closing body and html tags.
If need be, I can hardcode the required html into the above script, but if someone has an elegant, or not so elegant, solution on how to include these two files I'd appreciate it.
Thanks.
There's a function specifically for this called $.load(). It's always better to have a <div> with id and then use .innerHTML instead of using document.write().
$(function () {
$("#stuff").load("/path/to/api/call");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="stuff"></div>
If you have got multiple calls, that's fine too. Just have multiple containers.
$(function () {
$("#stuff").load("/path/to/api/call");
$("#pre").load("/path/to/api/code");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="stuff"></div>
<pre id="code"></pre>
One thing to note is that, $.load() fires an AJAX GET request.
place the contents of pre.content.php before the result and the contents of post.content.php
Don't use document.write. It gives you no control over where in the document you write anything. Instead, define the elements where you want to write your output:
<div id="pre-output"></div>
<div id="main-output"></div>
<div id="post-output"></div>
Then write your output to those specific locations:
pre = JSON.parse(data);
$('#pre-output').html(pre);
(Or maybe .text(pre)? It's strange to me that you're outputting raw JSON...)
******* SOLUTION *******
My main php has multiple tasks, so for this particular task the PHP is:
$output = " <div id='loading-gif'><img src='images/loading3.gif';></div>
<div id='main-output'></div>
<script>
$('#loading-gif').hide();
$(document).ready(function () {
$('#loading-gif').show();
$.ajax({url: 'https://aajumpseat.com/dev/scrape/getSegments.php'}).done(function (data) {
$('#loading-gif').hide();
output = JSON.parse(data);
//document.write(output);
$('#main-output').html(output);
});
});
</script>
<div class='bottom-border'></div>
";
and further down the page I have:
include('include/pre.content.php');
echo $output;
include('include/post.content.php');
And it is perfect.
I am trying to retrieve data from an api and use it to populate the div with the ID "output". I get an error that the $ is undefined. Can anyone help determine what I am missing?
<!DOCTYPE html>

var vname = response[1];
$('#output').html("<b>id: </b>"+id+"<b> name: </b>"+vname);
}
});

As Sirko already explained in the comments, you are trying to use the javascript library JQuery, but the library is not available because you didn't include it.
You can include it by either downloading JQuery here and including it via
<script src="src_to_local_jquery.js"/>
or by including it externally (described in CDN section of above link)
Also note, that script tags should be put either in the head or the body section. To make sure your custom script is executed after the page is ready, you can use JQuery's document ready method.
The $ sign is not part of the JavaScript language, it is a short hand for a third party library jQuery ($ === jQuery).
You need to add it as a dependency in your html file with a script tag with a src attribute containing the URI for the source file before you can use it.
<html>
<head></head>
<body>
...
...
<script src="//code.jquery.com/jquery-3.1.1.js"></script>
<script>
$(function () {
// Your code here
});
</script>
</body>
</html>
Include jQuery either as a CDN or download add reference locally. Then make sure the DOM is ready before you make the call. You can read more about that here
<script src="local_jquery.js"/>
// OR
<script src="https://code.jquery.com/jquery-3.1.1.js"></script>
$(function() {
$.ajax({
type: 'GET',
url: "https://apiurl.com",
dataType: "json",
crossDomain: true,
success: function( response ) {
console.log( response ); // server response
var id = response[0];
var vname = response[1];
$('#output').html("<b>id: </b>"+id+"<b> name: </b>"+vname);
}
});
});
When you press the link text it is supposed to give you an random string from a file, which it does on first click. But second click nothing happens, I need to refresh page before execute it again..
Code:
function randomName() {
$names = file('layout/sub/names.txt', FILE_IGNORE_NEW_LINES);
$array = array_rand($names);
return $names[array_rand($names)];
}
<div class="randomName">
</div>
<button class="aardvark">Pick random name</button>
<script>
$(document).on('click','.aardvark', function(e){
$('.randomName').html('<?php echo randomName(); ?>');
});
</script>
The issue is the age old PHP is server side and and javascript(jQuery) is client side problem, you cant call/run PHP from javascript as its already happened.
You will need to use AJAX to re-request a new name. Here is a copy and paste example, your welcome ;p
<?php
//is ajax
if(!empty($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
//is get name
if(isset($_POST['get_name'])){
$names = file('names.txt', FILE_IGNORE_NEW_LINES);
exit(json_encode(array('resp' => $names[array_rand($names)])));
}
}
?>

<?php
$v_var = $_POST["abc"];
print_r($_POST);
if(isset($_POST["abc"]))
{
echo $v_var;
}
else
{
echo "Data not received";
}
?>
When I run the ajax.html file ,I get success alert. But when I run ajaxphp.php file it shows notice like:
undefined index abc
Why is that the data is not received in $v_var ? where i am mistaking ?please help.
Actually the ajaxphp.php file is used to receive the data from the
post method and i will give response .
In First case by using ajax post method it will call to ajaxphp.php file.
In Second case your using direct file call without any post data(that's way it shows error)
Try this
var val = "hai"
$.post( "ajaxphp.php", {'abc':val}function( data ) {
alert( "Data Loaded: " + data );
});
jQuery expects an object as data, remove the double-quotes:
data: { abc : val }
I want to create a code that reloads a part of the page every 10 seconds and if it fails to reload (because of connection issue), then it plays a sound.
Is such thing possible using ajax and how? I have seen this type of feature in web chats before but never came across a code for it.
Try using setInterval function:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=windows-1250">
<title>Test</title>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" type="text/css">
<script src="http://code.jquery.com/jquery-1.9.1.js" type="text/javascript" language="JavaScript"></script>
<style type="text/css">
<!--
.square {
background-color: #AAAAAA;
width: 250px;
height: 100px;
}
//-->
</style>
<script type="text/javascript" language="JavaScript">
$(document).on('ready',function(){
setInterval(updateDiv,10000);
});
function updateDiv(){
$.ajax({
url: 'getContent.php',
success: function(data){
$('.square').html(data);
},
error: function(){
//Code to play a sound
$('.square').html('<span style="color:red">Connection problems</span>');
}
});
}
</script>
</head>
<body>
<h1>The next div will be updated every 10 seconds</h1>
<div class="square">
Hello
</div>
</body>
</html>
And the php script:
<?php
echo "Updated value --> " . rand();
?>
To test, try renaming the php script (simulating connection problems) and rename to original name (getContent.php) to test correct situation again. Hope this helps.
Using JQuery, you can add handlers to run on fail...
$.ajax({
dataType: "json",
url: "myurl.com"
}).done(function( data ) {
//do what you want when it's all good
}).fail(function() {
//do what you want when the call fails
});
Or you can do it this way...
$.ajax({
type: "post",
url: "/SomeController/SomeAction",
success: function (data, text) {
//do what you want when it's all good
},
error: function (request, status, error) {
//do what you want when the call fails
}
});
And per request, here is a jsfiddle, it calls a service every 2 seconds, either with a URL that will return the date, or with a bad URL that will fail, mimicking a failed server.
UPDATE: I modified the jsfiddle to play a sound, as long as that sound remains on the server it's on :)
