jquery dynamic content on ie - php

I have problem with the site I'm developing. The dynamically loaded div (ajax) is empty in IE9 and works poorly on firefox (php doesn't compile) and I can read the source of my php file in the div.
I've tried a lot of solutions like changing from GET to POST or adding a unique id to the url or making an async request but the content is absolutely empty. Any ideas? thanks
function pageload(hash) {
if(hash == '' || hash == null)
{
document.location.hash = "#php"; // home page
}
if(hash)
{
getPage();
}
}
function getUniqueTime() {
var time = new Date().getTime();
while (time == new Date().getTime());
return new Date().getTime();
}
function getPage() {
var str = getUniqueTime();
console.log(str);
var data = 'page=' + encodeURIComponent(document.location.hash);
$('#content').fadeOut(200);
$.ajax({
url: "loader.php?_=" + str,
type: "POST",
data: data,
cache: false,
success: function (html) {
$('#content').fadeIn(200);
$('#content').html(html);
}
});
}
EDIT:
//loader.php
<?
require_once('session.class.php');
require_once('user.class.php');
$se = new session();
$lo = new user();
$se->regenerate();
if(isset($_POST))
{
$alpha = (string) $_POST['page'];
if($alpha == '#php')
{
include 'homeloader.php';
}
else if($alpha == '#cplus')
{
include 'cplusloader.php';
}
else if($alpha == '#web')
{
include 'underloader.php';
}
else if($alpha == '#about')
{
include 'underloader.php';
}
else if($alpha == '#social')
{
include 'socialloader.php';
}
}
else
$page = 'error';
echo $page;
?>

try this:
//on click of a button:
$("#button").live("click", function(){
//get you string data
var str = "test";
//do new version of ajax
$.post("loader.php", {str:str}, function(html){
$('#content').html(html);
});
});
and you dont need to do AJAX method anymore $.post works amazing

php doesn't compile? async request? actually not specifying ascync: true the request is executed asyncroniously and in version jQuery 1.8 there is no sync AJAX requests at all. Attach an error handler and you will see that your request probably results an error:
...
cache: false,
success: function (html) {
$('#content').fadeIn(200);
$('#content').html(html);
},
error: function (a,b) {
alert('Error!');
}
...
Normally AJAX consists of 2 parts - client side and server side. I don't see serverside posted in your question. You have to check both of them. Make a simple loader.php returning the string success and get rid of all extra get params. First test your php file in browser to be sure that it works. Check FireBug for javascript errors ...

Retrieving page with anchor AJAX not working in IE

We released a site a couple of weeks ago and we are now getting complains that the website doesn't work in Internet Explorer 6-10.
Im using jQuery version: 1.11.0
We are running AJAX to load each page with an anchor. For example. www.site.com/#page2
Im trying to debug the code and see where it fails but I have no idea what is wrong.
The problem people are having is simple, the page doesn't load. All other code except the page call is working. So basically the page is empty.
This is a simplified version of the code:
function retrieve_page(link, lang){
event.preventDefault();
var id = link;
if(id){
document.location = "#"+id;
} else {
document.location = "#hem";
}
if(window.location.hash.substring(1) != "undefined") {
var page = window.location.hash.substring(1);
} else {
var page = "hem";
}
var content;
var request = $.ajax({
type: "GET",
url: "ajax/retriever.php",
data: { page:page },
success: function(data) {
content = data;
}
});
request.done( function () {
$('#page').html(content);
});
}
and this is the ajax/retriever.php file
<?php
$page = $_GET["page"];
$path = "../pages/".$page.".php";
$config = "../core/config.php";
if(!file_exists($path)){
require_once $config;
echo "<div id='no_page'><h1 style='display: block'>".$lang["ERROR"]."</h1><a href='index.php'><h2>".$lang["ERROR_RETURN"]."</h2></a></div>";
exit;
} else {
require_once $config;
require_once $path;
exit;
}
?>
The AJAX function call is example:
<a onclick="retrieve_page('page1', 'sv')">Page1</a>
Thanks in advance!
Can't see how i missed it. Well i solved the issue with simply removing event.preventDefault();

Two functions (Javascript and AJAX) dont work together

Im trying to send some data to the server through AJAX with the value i get from a JS variable.
Code:
<script type="text/javascript">
var url;
function aplicarFoto(_src) {
url = _src;
var fotosel = document.getElementById("fotosel");
fotosel.src = 'fotos/'+_src;
}
function guardarCambios() {
$.post("guardarCambios.php",
{url: url},
function(response) {
alert(response);
if (response == "NoUsuario") {
window.location = "../login.php";
} else {
alert("correcto");
}
}
alert(url);
}
</script>
The idea is update the user picture with the url i get from aplicarFoto(_src) with the variable url .
The first function (aplicarFoto(_src)) alone works correctly, but when i put the another function (guardarCambios()), the first function doesnt work, therefore the second neither! I dont know why, but it just happens when using ajax functions because i did a test with an alert(url) (sunrrounding the rest of code with comments) in the second function and both work correctly!
Some guess? Thank you!
Your script alone has syntax errors.
<script type="text/javascript">
var url;
function aplicarFoto(_src) {
url = _src;
var fotosel = document.getElementById("fotosel");
fotosel.src = 'fotos/' + _src;
}
function guardarCambios() {
$.post("guardarCambios.php", {
url: url
}, function (response) {
alert(response);
if (response == "NoUsuario") {
window.location = "../login.php";
} else {
alert("correcto");
}
alert(url);
}
);
}
</script>

SImple Ajax Jquery with php & mysql query

i look this tutorial
http://tutorialzine.com/2009/09/simple-ajax-website-jquery/
but i don't understand how to make this work with php file with sql, echo ""; etc
If someone can explain, i try everything and nothing appears
Thanks :)
var default_content = "";
$(document).ready(function () {
checkURL();
$('ul li a').click(function (e) {
checkURL(this.hash);
});
//filling in the default content
default_content = $('#pagesContent').html();
setInterval("checkURL()", 250);
});
var lasturl = "";
function checkURL(hash) {
if (!hash) hash = window.location.hash;
if (hash != lasturl) {
lasturl = hash;
// FIX - if we've used the history buttons to return to the homepage,
// fill the pageContent with the default_content
if (hash == "")
$('#pagesContent').html(default_content);
else
loadPage(hash);
}
}
function loadPage(url) {
url = url.replace('#page', '');

demo.html
< a href="#page1">Page1< /a>
< a href="#page2">Page2< /a>
< a href="#page3">Page3< /a>
< a href="#page4">Page4< /a>
<div id="pageContent">
//loaded ajax page
</div>
in this scenario , link > index.html#page1 will load file 'pages/page_1.php'
but in main index.html just can load html code , not php syntax .
Can I use php command in this case ?
So it looks like the problem here is that in the tutorials example, they simply use an HTML file. For this, file_get_contents() will work fine. However if you want your server to parse PHP code before serving it to the user, you should use the include() function.
From the documentation :
The include statement includes and evaluates the specified file.
The file_get_contents() function behaves silghtly differently :
file_get_contents — Reads entire file into a string
It simply reads the contents of the file, the PHP code is not evaluated/executed/interpreted...

jquery code snippet on load

I'm working with this code snippet plugin : http://www.steamdev.com/snippet/ for my blog
but the plugin doesn't work on page load.
It only works at first page refresh.
I load my content in a specific div with jquery.ajax request and i'm trying this :
$(window).on("load", function(){
$("pre.cplus").snippet("cpp",{style:"acid"});
$("pre.php").snippet("php",{style:"acid"});
});
I also tried to trigger the load event but i don't know if it is correct..
Another question : i build my html with php string like this example:
$string = '<pre class="cplus">
#include <iostream>
int main()
{
//c++ code
}
</pre>
<pre class="php">
<?php
function foo()
{
// PHP code
}
?>
</pre>';
echo $string; // ajax -> success
but the PHP snippet shows empty (the c++ is ok). Any other way (or plugin) to show php code snippet on my page?
Thank you.
SOLVED:
The problem isn't the plugin or Iserni suggestions.. i had a problem in page load (ajax)..
This is how i load the pages:
function pageload(hash) {
if(hash == '' || hash == '#php')
{
getHomePage();
}
if(hash)
{
getPage();
}
}
function getHomePage() {
var hdata = 'page=' + encodeURIComponent("#php");
//alert(hdata);
$.ajax({
url: "homeloader.php",
type: "GET",
data: hdata,
cache: false,
success: function (hhtml) {
$('.loading').hide();
$('#content').html(hhtml);
$('#body').fadeIn('slow');
}
});
}
function getPage() {
var data = 'page=' + encodeURIComponent(document.location.hash);
//alert(data);
$.ajax({
url: "loader.php",
type: "GET",
data: data,
cache: false,
success: function (html) {
$('.loading').hide();
$('#content').html(html);
$('#body').fadeIn('slow');
}
});
}
$(document).ready(function() {
// content
$.history.init(pageload);
$('a[href=' + window.location.hash + ']').addClass('selected');
$('a[rel=ajax]').click(function () {
var hash = this.href;
hash = hash.replace(/^.*#/, '');
$.history.load(hash);
$('a[rel=ajax]').removeClass('selected');
$(this).addClass('selected');
$('#body').hide();
$('.loading').show();
getPage();
return false;
});
// ..... other code for menus, tooltips,etc.
I know this is experimental , i have made a mix of various tutorials but now it works..
comments are much appreciated..
Thanks to all.
The PHP snippet seems empty because the browser believes it's a sort of HTML tag.
Instead of
$string = '<pre class="php">
<?php
function foo()
{
// PHP code
}
?>
</pre>';
you need to do:
// CODE ONLY
$string = '<?php
function foo()
{
// PHP code
}
?>';
// HTMLIZE CODE
$string = '<pre class="php">'.HTMLEntities($string).'</pre>';
As for the jQuery, it is probably due to where you put the jQuery code: try putting it at the bottom of the page, like this:
....
<!-- The page ended here -->
<!-- You need jQuery included before, of course -->
<script type="text/javascript">
(function($){ // This wraps jQuery in a safe private scope
$(document).ready(function(){ // This delays until DOM is ready
// Here, the snippets must be already loaded. If they are not,
// $("pre.cplus") will return an empty wrapper and nothing will happen.
// So, here we should invoke whatever function it is that loads the snippets,
// e.g. $("#reloadbutton").click();
$("pre.cplus").snippet("cpp",{style:"acid"});
$("pre.php").snippet("php",{style:"acid"});
});
})(jQuery); // This way, the code works anywhere. But it's faster at BODY end
</script>
</body>
Update
I think you could save and simplify some code by merging the two page loading functions (it's called the DRY principle - Don't Repeat Yourself):
function getAnyPage(url, what) {
$('.loading').show(); // I think it makes more sense here
$.ajax({
url: url,
type: "GET",
data: 'page=' + encodeURIComponent(what),
cache: false,
success: function (html) {
$('.loading').hide();
$('#content').html(hhtml);
$('#body').fadeIn('slow');
}
// Here you ought to allow for the case of an error (hiding .loading, etc.)
});
}
You can then change the calls to getPage, or reimplement them as wrappers:
function getHomePage(){ return getAnyPage('homeloader.php', "#php"); }
function getPage() { return getAnyPage('loader.php', document.location.hash); }
ok for the first issue I would suggest to
see what your JS error console saying
ensure correspondent js plugin file is loaded
and use the following code when you are using ajax (the key thing is "success" event function):
$.ajax({
url: 'your_url',
success: function(data) {
$("pre.cplus").snippet("cpp",{style:"acid"});
$("pre.php").snippet("php",{style:"acid"});
}
});
for the second issue lserni answered clearly
you need to use to jquery on load function like so:
$(function(){
RunMeOnLoad();
});

php mysql not saving data when button clicked and run $.ajax function

I have this
"fsField" is the class of all elements in the form. So whenever the user blurs to another field it submits the form using the function autosave() - given below. It saves data when the user blurs but when the user clicks the button with class "save_secL" to go to next page it does not save.
$('.fsField').bind('blur', function()
{
autosave();
}
});
but when i use this code
$('.save_secL').click(function()
{
var buttonid = this.id;
{
var answer = confirm("You have left some questions unanswered. Click OK if you are sure to leave this section? \\n Click CANCEL if you want stay in this section. ");
if(!answer)
{
var spl_items = valid().split(',');
$(spl_items[0]).focus();
return false;
}
else
{
$('#hidden_agree').append('<input id="secLuseragreed" name="secL_user_agreed" value="unanswered" type="hidden" />');
autosave();
window.location= buttonid+".php"
}
}
else
{
$('#hidden_agree').append('<input id="secLuseragreed" name="secL_user_agreed" value="answered all" type="hidden" />');
autosave();
window.location= buttonid+".php"
}
}
});
**autosave_secL.php is the php source thats saving the data in the database. I ran it independently and it does save data okay. **
function autosave()
{
var secL_partA_ques_1_select = $('[name="secL_partA_ques_1_select"]').val();
var secL_partA_ques_1 = $('[name="secL_partA_ques_1"]:checked').val();
var secL_partA_ques_2_select = $('[name="secL_partA_ques_2_select"]').val();
$.ajax(
{
type: "POST",
url: "autosave_secL.php",
data: "secL_partA_ques_1_select=" + secL_partA_ques_1_select + "&secL_partA_ques_1=" + secL_partA_ques_1 + "&user_id=<?php echo $row_token[user_id]?>" + "&updated_by=<?php echo $member."-".$key;?>",
cache: false,
success: function()
{
$("#timestamp").empty().append('Data Saved Successfully!');
}
});
}
**
valid() is a validation function that checks if any field is empty and returns a value if there is an empty field.**
function valid()
{
var items = '';
$('.fsField').each(function()
{
var thisname = $(this).attr('name')
if($(this).is('select'))
{
if($(this).val()=='')
{
var thisid = $(this).attr('id')
items += "#\"+thisid+\",";
$('[name=\"'+thisname+'\"]').closest('td').css('background-color', '#B5EAAA');
}
}
else
{
$('[name=\"'+thisname+'\"]').closest('td').css('background-color', '');
}
});
return items;
}
Can anyone please help? i am stuck for a day now. Can't understand why it saves when the user goes field to field but does not save when button is clicked with validation.
Tested with Firefox. this line appears in red with a Cross sign beside when the button(save_secL class) is clicked. I am using a ssl connection.
POST https://example.com/files/autosave_secL.php x
Here is the modified code trying to implement the solution
$('#submit_survey_secL').click(function()
{
if(valid() !='')
{
var answer = confirm("You have left some questions unanswered. Are you sure you want to Submit and go to Section B? ");
if(!answer)
{
var spl_items = valid().split(',');
$(spl_items[0]).focus();
return false;
}
else
{
$('#hidden_agree').append('<input id=\"secLuseragreed\" name=\"secL_user_agreed\" value=\"unanswered\" type=\"hidden\" />');
autosave(function(){
window.location= "part1secM.php?token=1&id=4"
});
}
}
else
{
$('#hidden_agree').append('<input id=\"secLuseragreed\" name=\"secL_user_agreed\" value=\"unanswered\" type=\"hidden\" />');
autosave(function(){
window.location= "part1secM.php?token=1&id=6"
});
}
});
function autosave(callback)
{
var secL_partL_ques_1_select = $('[name="secL_partL_ques_1_select"]').val();
var secL_partL_ques_1 = $('[name="secL_partL_ques_1"]:checked').val();
var secL_partL_ques_2_select = $('[name="secL_partL_ques_2_select"]').val();
$.ajax(
{
type: "POST",
url: "autosave_secL.php",
data: "secL_partL_ques_1_select=" + secL_partL_ques_1_select + "&secL_partL_ques_1=" + secL_partL_ques_1 + "&user_id=<?php echo $row_token[user_id]?>" + "&updated_by=<?php echo $member."-".$key;?>",
cache: false,
success: function()
{
$("#timestamp").empty().append('Data Saved Successfully!');
if($.isFunction(callback))
{
callback();
}
}
});
}
I don't understand why this doesn't work as callback should totally work. Firebug does not show POST https://example.com/files/autosave_secL.php in red any more but it shows that it has posted but I think the callback is not triggering for some reason
$('.save_secL').click(function() {
//...
//start autosave. Note: Async, returns immediately
autosave();
//and now, before the POST request has been completed, we change location...
window.location= buttonid+".php?token=$row_token[survey_token]&$member=$key&agr=1"
//....and the POST request gets aborted :(
Solution:
function autosave(callback)
{
//...
$.ajax(
{
//...
success: function()
{
$("#timestamp").empty().append('Data Saved Successfully!');
if($.isFunction(callback))
callback();
}
});
}
//and
autosave(function(){
window.location= buttonid+".php?token=$row_token[survey_token]&$member=$key&agr=1"
});
By the way, your autosave function is pretty hard for your server. Did you consider using localStorage + a final POST request containing all data?
I got the solution.
It might be one of the several. scr4ve's solution definitely helped. So here are the points for which I think its working now.
Moved "cache: false, " and removed "async:false" before url: in the ajax autosave function. Before I was putting it after "data: "
Added a random variable after autosave_secL.php/?"+Match.random()
Added scr4ve's solution so that POST is completed before redirect
