Change DIV content using ajax, php and jQuery - php

I have a div which contains some text for the database:
<div id="summary">Here is summary of movie</div>
And list of links:
Name of movie
Name of movie
..
The process should be something like this:
Click on the link
Ajax using the url of the link to pass data via GET to php file / same page
PHP returns string
The div is changed to this string

<script>
function getSummary(id)
{
$.ajax({
type: "GET",
url: 'Your URL',
data: "id=" + id, // appears as $_GET['id'] # your backend side
success: function(data) {
// data is ur summary
$('#summary').html(data);
}
});
}
</script>
And add onclick event in your lists
<a onclick="getSummary('1')">View Text</a>
<div id="#summary">This text will be replaced when the onclick event (link is clicked) is triggered.</div>

You could achieve this quite easily with jQuery by registering for the click event of the anchors (with class="movie") and using the .load() method to send an AJAX request and replace the contents of the summary div:
$(function() {
$('.movie').click(function() {
$('#summary').load(this.href);
// it's important to return false from the click
// handler in order to cancel the default action
// of the link which is to redirect to the url and
// execute the AJAX request
return false;
});
});

try this
function getmoviename(id)
{
var p_url= yoururl from where you get movie name,
jQuery.ajax({
type: "GET",
url: p_url,
data: "id=" + id,
success: function(data) {
$('#summary').html(data);
}
});
}
and you html part is
<a href="javascript:void(0);" class="movie" onclick="getmoviename(youridvariable)">
Name of movie</a>
<div id="summary">Here is summary of movie</div>

This works for me and you don't need the inline script:
Javascript:
$(document).ready(function() {
$('.showme').bind('click', function() {
var id=$(this).attr("id");
var num=$(this).attr("class");
var poststr="request="+num+"&moreinfo="+id;
$.ajax({
url:"testme.php",
cache:0,
data:poststr,
success:function(result){
document.getElementById("stuff").innerHTML=result;
}
});
});
});
HTML:
<div class='request_1 showme' id='rating_1'>More stuff 1</div>
<div class='request_2 showme' id='rating_2'>More stuff 2</div>
<div class='request_3 showme' id='rating_3'>More stuff 3</div>
<div id="stuff">Here is some stuff that will update when the links above are clicked</div>
The request is sent to testme.php:
header("Cache-Control: no-cache");
header("Pragma: nocache");
$request_id = preg_replace("/[^0-9]/","",$_REQUEST['request']);
$request_moreinfo = preg_replace("/[^0-9]/","",$_REQUEST['moreinfo']);
if($request_id=="1")
{
echo "show 1";
}
elseif($request_id=="2")
{
echo "show 2";
}
else
{
echo "show 3";
}

jQuery.load()
$('#summary').load('ajax.php', function() {
alert('Loaded.');
});

<script>
$(function(){
$('.movie').click(function(){
var this_href=$(this).attr('href');
$.ajax({
url:this_href,
type:'post',
cache:false,
success:function(data)
{
$('#summary').html(data);
}
});
return false;
});
});
</script>

<script>
function getSummary(id)
{
$.ajax({
type: "GET",//post
url: 'Your URL',
data: "id="+id, // appears as $_GET['id'] # ur backend side
success: function(data) {
// data is ur summary
$('#summary').html(data);
}
});
}
</script>

Ajax request load data from specific div? [duplicate]

my question is very simple how can I retrieve certain div with jquery ajax comand
$.ajax({
url: "test.html",
success: function(){
$(this).addClass("done");
}
});
like with load
$('#targetDiv').load('http://localhost/test.html #sourceDiv');
If the div is part of the AJAX response:
$.ajax({
url: 'test.html',
dataType: 'html',
success: function(html) {
var div = $('#sourceDiv', $(html)).addClass('done');
$('#targetDiv').html(div);
}
});
Here is a slightly different take on it. Also your target div maybe hidden by default so I've added in a Fade In affect to show it. If your html is going to change then you might want to add in a cache: false.
$.ajax({
url: "html.htm",
type: "GET",
dataType: "html",
success: function (res) {
$("#targetDiv").html($(res).find("#sourceDiv")
.addClass('done'))
.fadeIn('slow');
}
});
If you're interested you can take a look at how jQuery does the load method here jQuery Source Viewer
Here is an example that I use on my site for the navigation.
<ul id="nav">
<li><a name="portfolio" href="portfolio.php" class="ajax_nav">PORTFOLIO</a></li>
<li><a name="biography" href="biography.php" class="ajax_nav">BIOGRAPHY</a></li>
</ul>
For the javascript you can try this.
var hash = window.location.hash.substr(1);
var hash2 = window.location.hash.substr(1);
// Menu items to lower main content
var href = $('.ajax_nav').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.html #ajax_content';
$('#ajax_content').load(toLoad)
}
});
// For inner overlay of featured content.
var href2 = $('.feat_item_link').each(function(){
var href2 = $(this).attr('href');
if(hash2==href2.substr(0,href.length-4)){
var toLoadFeatured = hash2+'.html #ajax_featured_content';
$('#ajax_featured_content').load(toLoadFeatured);
}
});
// For Bottom Navigation
$('#nav li a').click(function(){
var toLoad = $(this).attr('href')+' #ajax_content';
$('#content').hide('fast',loadContent);
$('#load').remove();
$('#wrapper').append('<span id="load">LOADING...</span>');
$('#load').fadeIn('normal');
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href'));
function loadContent() {
$('#content').delay(1000).load(toLoad,'',showNewContent());
}
function showNewContent() {
$('#content').show('normal',hideLoader());
}
function hideLoader() {
$('#load').delay(1000).fadeOut('normal');
}
return false;
});
The id of #load simply uses an animated gif in the CSS.
Place the javascript in the $(document).ready() and you should be all set.

Load a data from a page to another page using jquery ajax

I have two pages, index.php and block1.php
I wanted to load a data from block1.php to a div #details in index.php
here's my code
index.php
<div id="pop_box">
<div class="close"><span id="close">×</span></div>
<div id="block"></div>
<div id="details"></div>
</div>
block1.php
<script>
$(document).ready(function() {
var lnk;
$('[href]').click(function() {
lnk = '';
lnk = $(this).attr('href');
if (lnk.charAt(1) == "b") {
var lot = lnk;
$.ajax({
url: "2dmap_func.php",
method: "POST",
dataType: "text",
data: {
lot: lot
},
success: function(data) {
//alert(data);
$('index.php #pop_box #details').load(data);
}
});
}
});
});
</script>
as you can see I want to load the data from block1.php to index.php's div#details and this code doesn't work.
$('index.php #pop_box #details').load(data);
In you index.php add following line:
<?php include_once 'block1.php' ?>
In your block1.php change following line:
$('index.php #pop_box #details').load(data);
to
$('#details').html(data); // if data is valid html

add waiting message before load remote data in bootstrap modal box

I have this code for load remote php data into bootstrap modal box:
$(function() {
$(window).bind("resize", function() {
if ($(this).width() < 400) {
$('#tabs-content').removeClass('col-xs-10').addClass('col-xs-12')
} else {
$('#tabs-content').removeClass('col-xs-12').addClass('col-xs-10')
}
}).resize();
});
$(function() {
$(document).on('click', '.push', function(e) {
e.preventDefault();
var id = $(this).attr('id');
$.ajax({
type: 'post',
url: 'details.php', // in here you should put your query
data: {
'bookid': id,
'lang': 'fa',
'csrf_token': 'MTQ0OTQxNDQ0MUVvN2JwNXNJRHVxMDZmOXFpQm1ROFNNTk1UZ3lPMGZO'
},
success: function(r) {
// now you can show output in your modal
$('#bookdetails').modal({
backdrop: 'static',
keyboard: false
}) // put your modal id
$('.something').show().html(r);
}
});
});
});
This worked for me But I need to show loading message/image before load data.
How do add waiting message/icon?!
You just need to show image/message before Ajax call and hide it in success: function(r)
Assuming you have image which to show before modal load, image HTML e.g
<img class="progress" src="http://downgraf.com/wp-content/uploads/2014/09/01-progress.gif" style="display:none;">
and in JS, just show image with .show() function and after modal load in success: function(r) hide is with .hide() function
$(document).on('click', '.push', function(e) {
e.preventDefault();
var id = $(this).attr('id');
$(".progress").show(); // <-- Show progress image
$.ajax({
type: 'post',
url: 'details.php', // in here you should put your query
data: {
'bookid': id,
'lang': 'fa',
'csrf_token': 'MTQ0OTQxNDQ0MUVvN2JwNXNJRHVxMDZmOXFpQm1ROFNNTk1UZ3lPMGZO'
},
success: function(r) {
// now you can show output in your modal
$('#bookdetails').modal({
backdrop: 'static',
keyboard: false
}) // put your modal id
$('.something').show().html(r);
$(".progress").hide(); // <-- Hide progress image
}
});
});

AJAX / PHP error handling and global variable

this is my first time writing an ajax below is my structure
submitted.php
<?php $a = $_POST['a']; // an input submitted from index.php ?>
<button>bind to jquery ajax</button> // call ajax
<span></span> // return ajax result here
<script>
$('button').on('click', function() {
event.preventDefault();
$.ajax({
method: "POST",
url: "test.php",
data: { "key" : 'data'}
})
.done(function( msg ) {
$('span').html(msg);
});
});
</script>
test.php
<?php echo $a; // will this work? ?>
ajax return blank... no error, my error_reporting is on.
No, there are a few things wrong with this:
You are posting a key - value pair where the key is key, so you would need $_POST['key'] in your php script;
You should use .preventDefault() if you need to prevent an event like a form submit that is caused by your button. If that is the case, you need to get the event variable from your event handler: $('button').on('click', function(event) {.If there is no event to prevent, you can simply remove that line;
If you do have a form (it seems so from your comment), you can easily send all key - value pairs using: data: $('form').serialize().
form.php
<button>bind to jquery ajax</button> <!-- ajax trigger -->
<span></span> <!-- return ajax result here -->
<script>
// NOTE: added event into function argument
$('button').on('click', function(event) {
event.preventDefault();
$.ajax({
method: "POST",
url: "test.php",
data: { "key" : 'data'}
})
.done(function(msg) {
$('span').html(msg);
});
});
</script>
process.php
<?php
echo (isset($_POST['key'])) ? $_POST['key'] : 'No data provided.';
?>
This is the way to do it:
ubmitted.php
<button>bind to jquery ajax</button> // call ajax
<span></span> // return ajax result here
<script>
$('button').on('click', function() {
// no need to prevent default here (there's no default)
$.ajax({
method: "POST",
url: "test.php",
data: { "key" : 'data'}
})
.done(function( msg ) {
$('span').html(msg);
});
});
</script>
test.php
<?php
if (isset($_POST['key'])
echo $_POST['key'];
else echo 'no data was sent.';
?>

JQuery alternate div content and AJAX post url on each click

I have some JQuery handling a div click. If the div is clicked once it hides itself and shows another div (and posts to a php script in the background). If it is then clicked again, it's supposed to hide the new div, show the new one again, and post more data to a different script, and so on.
It changes the first time (.f hides, .uf shows) but when I click '.uf' nothing happens.
JQuery:
if($('.f').is(":visible")) {
$('#follow').click(function() {
var to_follow = $('.name').attr('id');
$.ajax({
type: "POST",
url: "/bin/rel_p.php",
data: "y=" + to_follow,
success: function() {
$('.f').hide();
$('.uf').show();
}
});
});
}
else {
$('#follow').click(function() {
var to_unfollow = $('.name').attr('id');
$.ajax({
type: "POST",
url: "/bin/relu_p.php",
data: "y=" + to_follow,
success: function() {
$('.uf').hide();
$('.f').show();
}
});
});
}
HTML:
<div id="follow" class="f">
<img src="img/icons/Follow.png">
<h1>Follow</h1>
</div>
<div id="follow" class="uf" style="display:none;">
<img src="img/icons/Unfollow.png">
<h1>Unfollow</h1>
</div>
use a class if you intend to use the selector twice, and don't write the same code twice unless you have to:
$('.follow').on('click', function() {
var is_f = $('.f').is(":visible"),
to_follow = $('.name').attr('id'),
give_me_an_u = is_f?'':'u';
$.ajax({
type: "POST",
url: "/bin/rel" + give_me_an_u + "_p.php",
data: {y : to_follow}
}).done(function() {
$('.f, .uf').toggle();
});
});
