Loading Javascript with AJAX - php

I have this neat little code:
<script type="text/javascript" language="javascript">
$(function(){
$(window).hashchange( function(){
window.scrollTo(0,0);
var hash = location.hash;
if (hash == "") {
hash="#main";
}
var newhash = !/\.php$/i.test(hash)? hash+".html": hash;
ajax_loadContent('m',newhash.slice(1,newhash.length));
$('.menu li a').each(function(){
var that = $(this);
that[ that.attr( 'href' ) === hash ? 'addClass' : 'removeClass' ]( 'current' );
});
})
$(window).hashchange();
});
</script>
The only problem is that if I navigate to pages containing Javascript that code isn't being executed. How can I make it run the Javascript code as if the browser loaded the page normally?

It will not be execute as it comes as text. You have to use "eval" function on your response text

load page at its hash, then display the result directly without showing the index first

on http://zentili.koding.com i've got this javascript that loads the content of the linked menu item inside the main #content div of the index page, and applies an hash with the name of the loaded page minus the '.php', otherwise it loads the hash + '.php' if it's entered in the url. works very good. On other hand, the ENG/ITA entries add ?locale=lang_LANG inside the url, right before the hash, so that localization is also working fine. If you look well, you may notice that when you switch between ENG and ITA, the index-content appears just for one moment before going to the hash. I know this is because the page is first loaded, then taken to the hash but i was wondering if there some way for hiding the homepage and going directly to the hash location when it's loaded.
Here the code for my menu:
<script type="text/javascript">
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('#menubar a.item').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php';
$('#content').load(toLoad);
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
}
});
$('#menubar a.item').click(function(){
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
var toLoad = $(this).attr('href');
$('#content').fadeOut('fast',loadContent);
function loadContent() {
$('#content').load(toLoad,'',showNewContent) }
function showNewContent() {
$('#content').fadeIn('fast'); }
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
return false;
});
});
function goENG(){
var hash = window.location.hash;
var eng = '?locale=en_EN';
window.location.replace(eng+hash) ;
};
function goITA(){
var hash = window.location.hash;
var ita = '?locale=it_IT';
window.location.replace(ita+hash) ;
};
</script>
the functions goENG() and goITA() are called via onclick on the ENG and ITA a's. I hope to find some solution into this.
The page cannot directly go to the link. It will load in its natural order and then it will go to the hash. For what you want to achieve, there is a simple solution i believe.
Hide the main content div until the document loads. use css rule "visibility:hidden" for this
If there is any hash, load it and then make the content visible.
If there is no hash in url, make the content visible on dom load.
$(document).ready(function() {
var hash = window.location.hash.substr(1);
if ($('#menubar a.item').length > 0) {
var href = $('#menubar a.item').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php';
$('#content').load(toLoad, function(){
$('#content').attr('visibility', 'visible');
});
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
} else {
$('#content').attr('visibility', 'visible');
}
});
} else {
$('#content').attr('visibility', 'visible');
}
});
--UPDATE--
If you are setting #content as "visibility:hidden"
$('#content').attr('visibility', 'visible');
should always fire, else your #content div will be invisible. The trick here is to set it to visible after we are done with checking for hash. You can keep loading the content in the div and make it visible. Making the #content div visible need not be done after entirely loading the hash.

JQuery after AJAX GET

I have this AJAX GET:
function edit(str){
ajax.onreadystatechange=function()
{
if (ajax.readyState==4 && ajax.status==200)
{
document.getElementById("editaircraftdialog").innerHTML=ajax.responseText;
$("#editaircraftdialog").dialog('open');
$("#loadingdialog").dialog('close');
}
}
ajax.open("GET","./edit_aircraft.php?icao="+str,true);
ajax.send();
$("#loadingdialog").dialog('open');
}
The JQuery code in edit_aircraft.php does not work. Here's an example:
<script>
$(function() {
$("#insertaircraft")
.button()
.click(function(event) {
});
});
</script>
I have had the same problem in the past and I cannot fix it.
You can not load JavaScript with innerHTML. It does not get evaluated.
Use jQuery to your advantage
function edit(str){
var loading = $("#loadingdialog").dialog('open');
var aircraft = $("#editaircraftdialog");
aircraft.load("./edit_aircraft.php?icao="+str, function(){
loading.dialog('close');
aircraft.dialog('open');
});
}

How to make a secondary document ready function?

Ok this is my issue if anyone can help, please.
I have a href that div id to switch content - I would like to add another document ready function javascript without conflicting with make tab I have already.
Example of make tab already:
<script type="text/javascript">
{literal}
$(document).ready(function(){
function makeTabs(selector) {
var tabContainers = $(selector + ' > div');
tabContainers.removeClass("selected").filter(':first').addClass("selected");
galleryRendered = false;
$(selector + ' > ul a').click(function () {
tabContainers.removeClass("selected");
tabContainers.filter(this.hash).addClass("selected");
$(selector + ' > ul a').removeClass('selected');
$(this).addClass('selected');
if (this.hash == '#Pictures' && !galleryRendered)
{
var galleries = $('.pictures > .ad-gallery').adGallery({
effect : 'slide-hori',
enable_keyboard_move : true,
cycle : true,
animation_speed : 400,
slideshow: {
enable: false
},
callbacks: {
init: function() {
this.preloadImage(0);
this.preloadImage(1);
this.preloadImage(2);
}
}
});
galleryRendered = true;
}
if (this.hash == '#OnTheMap') document.getElementById("Map").map.onContainerChanged();
return false;
}).filter(':first').click();
}
makeTabs('.tabs');
});
{/literal}
</script>
Want to create a second one so I can create tabs inside of an existing div id area/content to switch from photo to video to youtube.
<div class=".tabs"><ul><li>[[Photo]]</li><li>[[Youtube]]</li><li>[[Video]]</li></ul><div id="photo">Test</div><div id="tube">Test</div><div id="vid">Test</div></div>
This will be inside a div id that already exist that uses the first tab creator shown above.
In jQuery you just have to do this:
$(function(){
// code here
});
$(function(){
// more code here
});
Every function declared like this will be executed on domready.

Redirect From a Js File

I am using this code in php or html file for redirect
<script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>
<script language="JavaScript">
var country= geoip_country_code();
if(country == "US" )
{
<!--
window.location = "http://google.com"
//-->
}
</script>
but i want to use a js file which do the same function but its extension should be .js
as http://domain.com/redirect.js so what would be the code?
This includes a script include function with a callback, so that the Maxmind client code won't run until the Maxmind library has been loaded.
loadScript("http://j.maxmind.com/app/geoip.js", function() {
var country = geoip_country_code();
if (country === "US") {
window.location = "http://google.com/";
}
});
function loadScript(url, callback) {
// adding the script tag to the head as suggested before
var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.src = url;
// then bind the event to the callback function
// there are several events for cross browser compatibility
script.onreadystatechange = callback;
script.onload = callback;
// fire the loading
head.appendChild(script);
}

Jquery textinput change function is not working

I just get the parameters from PHP GET method and use them using jQuery. There is no output when run the page.
<?php
if (isset($_GET['url'])){
$url = $_GET['url'];
$url = explode(" " , $url);
echo end($url);
exit;
}
?>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.7.1.js"></script>
<script type="text/javascript">
$('input[type=text]').change(function (){
if ($(this).val() !== ''){
var url = $(this).val():
$.post('grab.php?url='+url+'', function (data){
window.open(data, 'Download', 'width=10,height=10');
$(this).html('');
});
}
});
</script>
</head>
<body>
<input type="text" style="width:100%;height:20px;"/>
</body>
</html>
I'm new to designs and hope mistake is there.
First of all put your document in standards mode (by using a proper doctype at the beginning, which means HTML 4/XHTML 1 strict or HTML 5). Then you can use error console for debugging.
I found following error
Unexpected token: ':' on line 7,
The colon should be a semicolon.
var url = $(this).val():
And then, the actual reason why nothing is happening is because the input is non-existent when the script is invoked/cached. You need to execute it after the DOM has been constructed.
$(document).ready(function() {
// content
});
Final code.
$(document).ready(function() {
$('input[type=text]').change(function (){
if ($(this).val() !== ''){
var url = $(this).val();
$.post('grab.php?url='+url+'', function (data){
window.open(data, 'Download', 'width=10,height=10');
$(this).html('');
});
}
});
});
put it in $(document).ready() like this:
$(document).ready(function() {
$('input[type=text]').change(function (){
if ($(this).val() !== ''){
var url = $(this).val():
$.post('grab.php?url='+url+'', function (data){
window.open(data, 'Download', 'width=10,height=10');
$(this).html('');
});
}
});
});
I think using a .change event on a text input isn't advisable. Usually .blur and .focus are more appropriate.
$(document).ready(function() {
$('input[type=text]').blur(function(){
var currentInput = this;
if ($(currentInput ).val() != ''){
var url = $(currentInput ).val();
$.post('grab.php?url='+url, function(data){
window.open(data, 'Download', 'width=10,height=10');
$(currentInput).val('');
});
}
});
});
