I am integrating my site ajax to load content without reloading the page. Everything works fine but are of this style url http: // mysite / #.
I wish that were generated url to reload the page to remain in the same place, I could use also have a new URL for the likes of facebook. Any idea what could be wrong? I leave the code:
function nuevoAjax() {
var xmlhttp = false;
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (E) {
xmlhttp = false;
}
}
if (!xmlhttp && typeof XMLHttpRequest != 'undefined') {
xmlhttp = new XMLHttpRequest();
}
return xmlhttp;
}
function Cargar(url) {
var center = document.getElementById('center');
ajax = nuevoAjax();
ajax.open("GET", url, true);
ajax.onreadystatechange = function () {
if (ajax.readyState == 4) {
center.innerHTML = ajax.responseText;
}
}
ajax.send(null);
}
And the button:
<img src="<?php $_SERVER['DOCUMENT_ROOT']?>/image/road.jpg" width="60" height="34"/>
This is the div that loads dynamic content
<div class="center"></div>
New EDIT:
<sript src:"https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$("#loadContent").on("click",function(event){
event.preventDefault();
$.ajax({
url: $(this).attr("href"),
type: 'GET',
data: {"anydata":"anydatavalue"},
success : function(reponse){
$("#center").html(reponse);
}
});
});
</script>
The button:
<li>BIO</li>
This is a code to do the task that you want in jquery ajax
include jquery file in the head of your page like this
<sript src:"https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script
assign a id to your anchor tag
<img src="<?php $_SERVER['DOCUMENT_ROOT']?>/image/road.jpg" id="loadContent" width="60" height="34"/>
Jquery Ajax bind with click event
<script>
$("#loadContent").on("click",function(event){
event.preventDefault();
$.ajax({
url: $(this).attr("href"),
type: 'GET',
data: {"anydata":"anydatavalue"},
success : function(reponse){
$("#center").html(reponse);
}
});
});
</script>

I want to autoupdate page using PHP and Ajax. Right now I have this code on a page:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>
</head>
<body>
<i class="fa fa-heart-o"></i>
</body>
</html>
When the user clicks on the link it is redirected to another page called "Page-Like.php"
include("config.php");
//get vars
$idSubliminal=$_GET["idSubliminal"];
$idCategoria=$_GET["idCategoria"];
// mysql_query("insert into Rating .... (mysql insert query)
echo "<script>
location.href=\"AudioSubliminal.php?idSubliminal=$idSubliminal&idCategoria=$idCategoria\";
</script>";
What I want is to do this usig Ajax in order to not refresh the page. I know I'm missing the javascript code, but I would like to get some suggestions to complete this script.
Thanks!
All you need is a basic ajax request to achieve your functionality. check the sample request below.
function ajaxpr(){
var URLString="idSub=12&idCat=32";
ajax_request = $.ajax({
type: 'GET',
url: "Page-Like.php",
data: URLString,
dataType : 'html',
context: $(this),
success: function (msg)
{
//perform the required operation after success
});
}
add function onclick on tag . then define that function using :
$.ajax({
type: 'GET',
data: {idSub: "12", idCat: "32"},
url: "Page-Like.php",
dataType: 'JSON',
success: function (response, textStatus, jqXHR) {
//DEFINE FUNCTION HERE
}
});
This is using ajax function without refresh page.
You can use many methods to implement Ajax on you're code.
One of this is jQuery, other is mootools, etc.. Depends of wich library you know or want to learn.
Using ajax to load a page is easy. Follow this link http://www.w3schools.com/ajax/
function loadDoc() {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
// Change this to your desired DOM tag
document.body.innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", "Page-Like.php?idSub=12&idCat=32", true);
xhttp.send();
}
Now it's just a matter of putting event listener to run loadDoc() function. If the link is dynamic, you can parse the parameter to the function.
However, I notice you have a js script inside your php which will redirect again to AudioSubliminal.php. If this is your desired flow then it's okay. If not, you can create another function
function loadAudioSubliminal(idSub, idCat) {
var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
if (xhttp.readyState == 4 && xhttp.status == 200) {
// Change this to your desired DOM tag
document.body.innerHTML = xhttp.responseText;
}
};
xhttp.open("GET", "AudioSubliminal.php?idSubliminal=" + idSub + "&idCategoria=" + idCat, true);
xhttp.send();
}
and modified loadDoc() to receive a parameter such that idSub and idCat can be passed again. for Example :
function loadDoc(idSub, idCat) {
var xhttp = new XMLHttpRequest();
if (xhttp.readyState == 4 && xhttp.status == 200) {
// Change this to your desired DOM tag
document.body.innerHTML = xhttp.responseText;
// run the function after finished loading Page-like.php
loadAudioSubliminal(idSub, idCat)
}
xhttp.open("GET", "Page-Like.php?idSub=" + idSub + "&idCat=" + idCat, true);
xhttp.send();
}
I'm having a bit of trouble understanding how to get this to work. I'm loading a page with data from mysql db table using jquery. I'd like to be able to do mysql updates on individual records without refresh. Here's the code I've tried, but can't get the update to work.
index.php
function showUser(str) {
if (str == "") {
document.getElementById("txtHint").innerHTML = "";
return;
} else {
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else {
// code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function() {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("txtHint").innerHTML = xmlhttp.responseText;
}
}
xmlhttp.open("GET","data_ajax.php?q="+str,true);
xmlhttp.send();
}
}
Here I have a drop-down in a while loop to retrieve the desired records and post it into a <div id="txtHint"></div>. So far, so good.
Now, I'm putting the following in data_ajax.php to do the mysql update.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript">
$(function() {
$(".update_button").click(function() {
var id = $(this).attr("id");
var dataString = 'id='+ id ;
var parent = $(this).parent();
$.ajax({
type: "POST",
url: "update_ajax.php",
data: dataString,
cache: false,
});
return false;
});
});
</script>
Where I have a text link <a href='#' id='".$row['id']."' class='update_button'>".$label."</a> that should call the action above to do the update. All this does it jumps the page to the top and nothing happens. The update_ajax.php doesn't seem to get called when link is clicked. I know it's something simple I'm missing. Any help would be appreciated.
What I would suggest is including jQuery directly in index.php, which would then allow you to use event delegation to handle most of the work.
With jQuery being included in index.php, you can use jQuery to do the showUser ajax request too.
function showUser(str) {
if (str == "") {
$("#txtHint").empty();
return;
}
$("#txtHint").load("data_ajax.php?q=" + str);
}
$(document).ready(function () {
$("#txtHint").delegate(".update_button", "click", function () {
var id = $(this).attr("id");
var dataString = 'id='+ id ;
var parent = $(this).parent();
$.ajax({
type: "POST",
url: "update_ajax.php",
data: dataString
});
return false;
});
});
Update your version of jQuery. Your example shows you using version 1.4.2.
The $.ajax shorthand code was introduced after version 1.5.
I have an ajax call. This script is working fine when I put it in one file with the form that will be loaded with the script.
$(document).ready(function () {
$("#uploadbutton").click(function () {
var referenceNumber = document.getElementById('referenceNumber').value;
$.ajax({
type: "POST",
url: "selectReferenceOrder.php",
data: 'referenceNumber='+referenceNumber,
cache: false,
//data: $('form').serialize(),
success:function(html)
{
document.getElementById('outputReference').innerHTML = html;
alert('referenceNumber');
}
});
});
});
However, when I try to put it in an external file, it doesn't give me anything.
The script of this ajax is functioned as the script that will post the form into the php file.
Reference: <input type="text" id="referenceNumber" />
<input type="button" id="uploadbutton" value="SEARCH"/>
I have tried many ways of doing this, but it still doesn't work:
<input type="submit" value="SEARCH" onclick="collectActed()" />
function collectActed () {
var referenceNumber = document.getElementById('referenceNumber').value;
$.ajax({
type: "POST",
url: "selectReferenceOrder.php",
data: 'referenceNumber='+referenceNumber,
cache: false,
success:function(html) {
document.getElementById('outputReference').innerHTML = html;
}
});
}
Please, help.
Following code works well:
<html>
<head>
<title>Ajax Search</title>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script type="text/javascript">
function searchFor(suchbegriff) {
var xmlHttp = null;
// Mozilla, Opera, Safari sowie Internet Explorer 7
if (typeof XMLHttpRequest != 'undefined') {
xmlHttp = new XMLHttpRequest();
}
if (!xmlHttp) {
// Internet Explorer 6 und älter
try {
xmlHttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
try {
xmlHttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
xmlHttp = null;
}
}
}
// If object has been created
if (xmlHttp) {
var url = "search.php";
var params = "search=" + search;
xmlHttp.open("POST", url, true);
//Headerinformatio for POST request
xmlHttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");
xmlHttp.onreadystatechange = function () {
if (xmlHttp.readyState == 4) {
// Zurückgeliefertes Ergebnis wird in den DIV "ergebnis" geschrieben
document.getElementById("result").innerHTML = xmlHttp.responseText;
}
};
xmlHttp.send(params);
}
}
</script>
<script>
$(document).ready(function(){
$("input").click(function(){
$("div").load("search.php");
});
});
</script>
</head>
<body>
<input type="text" onkeyup="searchFor(this.value);"/>
<div id="search"></div>
</body>
</html>
I want to retrieve all elements from an ajax call, then insert them into another element without:
using jquery (I just want to use pure JavaScript)
creating a new element to contain the ajax response
Here's what I have tried:
index.php
<!DOCTYPE HTML>
<head>
<script type="text/javascript">
function loadPage() {
var ajax = new XMLHttpRequest();
ajax.open('GET', 'test.php', true);
ajax.onreadystatechange = function (){
if(ajax.readyState === 4 && ajax.status === 200){
document.getElementById('output').appendChild( ajax.responseText ) ;
}
};
ajax.send();
}
loadPage();
</script>
</head>
<body>
<div id="output">
<h1>Default</h1>
</div>
</body>
</html>
test.php
<h1>
its work
</h1>
<div>
<h2>
its work2
</h2>
</div>
I already googled it, but the answer was always to use jQuery.
Node.appendChild requires a Node object as an argument. What you're getting from test.php is a string. Try using innerHTML instead
document.getElementById('output').innerHTML = ajax.responseText;
As of XHR level 2, you can simply attach an onload handler to XHR instead of checking the readyState and status properties.
ajax.onload = function() {
document.getElementById('output').innerHTML += this.responseText;
}
have you looked at this
http://w3schools.com/ajax/ajax_examples.asp
http://w3schools.com/ajax/tryit.asp?filename=tryajax_first
I think the most of the examples that you find use jquery because jquery makes it cross browser
try this one
function loadPage(){
var strURL="test.php";
var req = getXMLHTTP();
if (req) {
req.onreadystatechange = function() {
if (req.readyState == 4) {
// only if "OK"
if (req.status == 200) {
document.getElementById('output').value=req.responseText;
} else {
alert("There was a problem while using XMLHTTP:\n" + req.statusText);
}
}
}
req.open("POST", strURL, true);
req.send(null);
}
}
function getXMLHTTP() { //function to return the xml http object
var xmlhttp = false;
try {
xmlhttp = new XMLHttpRequest();
} catch (e) {
try {
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
} catch (e) {
try {
xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");
} catch (e1) {
xmlhttp = false;
}
}
}
$('#show_mess').click(function (){
$('#dropdown_mess').slideToggle("slow");
$('#arrow_mess').slideToggle("slow");
$('#arrow_not').hide("slow");
$('#dropdown_not').hide("slow");
function recall(){ setTimeout(function () {
xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", "http://localhost/ajax/mess_data.php", true);
xmlhttp.onreadystatechange = function () {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById('dropdown_mess').innerHTML = xmlhttp.responseText;
}
}
xmlhttp.send();
document.getElementById('dropdown_mess').innerHTML = "<img class='non_auto' id='ajax_loading' src='img/ajax_loading.gif'></img>";
recall();
}, 2000);
};
recall();
});
this function works fine but when each ajax call is done i need to colse and re-oper chrome in order to work, works fine in firefox
You are already using Jquery so why don't you try it's ajax function like below
$.ajax({
url: "test.html",
context: document.body
}).done(function() {
....
});
