Get current URL from document.ready - javascript

I am trying to parse my URL in document.ready() so that I can get the id of the current page and dynamically populate the page with results from an AJAX call. The problem I am running into is due to the fact that I think that 'document.URL' references the previous page until 'document.ready()' has fully executed.
How do I get around this? I have researched document.load(), and auto-refreshing the page once, but I cannot seem to get this to work. I have been working on this since yesterday.
Here is my code:
$( document ).ready( function(){
var id = document.URL.substring(document.URL.lastIndexOf('?')+4);
if(!loadObject.executed) {
loadObject(id);
loadObject.executed = true;
} else {
$('#page-full').on('pagecreate', loadObject(id));
}
});

Try to use document.location.href instead of document.URL.
Hope this helps.

Ajax loaded part of a page - how do I make links in the loaded content work?

I load a part of my basketpage inside an accordion div in my header. This works great and shows my basket in a nice dropdown.
The last problem I need to solve with this is to get the buttons in the loaded content to work. Is it possible to write an callback that make these works? Im not sure even what to google for this one..
This is how the buttons is setup in the loaded content:
checkout
Script Im using to load the content:
$('.dcjqg-accordion ul.sub-menu').load('/m4n?seid=etailer-basket div#centerbox.itembox.centerbox');
use the callback function of .load().
$('.dcjqg-accordion ul.sub-menu').load('/m4n?seid=etailer-basket div#centerbox.itembox.centerbox', function() {
$("#_ec_oie2").on("click", function() {
if (UI.pb_boolean(this, 'click')) { }
return false;
});
});
checkout
You need to use a child selector for the event. You can attach an event to the .sub-menu element that will fire on the content loaded in through the ajax. Something like the following could work:
$(".dcjqg-accordion ul.sub-menu").on("click", ".action.actionbasket.checkout", function() {
if( UI.pb_boolean(this, 'click') ) {}
return false;
});
Notice the second parameter to the on method. It is a selector that will be used to look at the target of the click event. I used .action.actionbasket.checkout since that is what is on your a tag.
This code may not work exactly, but this should help get you in the right direction.
Here is the link to the jQuery documentation for the on method: https://api.jquery.com/on/

pagecontainer change function not working

I can get the pagecontainer change function to work inside a function that is called with a button click. But for some reason the pagecontainer change function isn't working when I run the code outside of a function. I do a check to see if a user is logged in and then want to do a page change/redirect if they aren't logged in.
<script>
//works
function test() {
$(':mobile-pagecontainer').pagecontainer('change', '#event-list-page');
}
//doesn't work
var user = window.localStorage.getItem("user");
if (user == null){
alert('not logged in. Should redirect.');
$(':mobile-pagecontainer').pagecontainer('change', '#event-list-page');
}
</script>
What is the best solution for this problem? Should I just do a javascript redirect? Or do I need to wait for the page to load all the way or something?
You should intiate the $.mobile.pageconatiner first, example:
$.mobile.pageContainer.pagecontainer({ defaults: true });
I think that the jQuery mobile has to have the entire page loaded first because it does a bunch of funny things pre-loading pages and doing ajax transitions and things. It's not a simple redirect like setting window.location. If you pt it in a document.ready block it will work.
$( document ).ready(function() {
$.mobile.pageContainer.pagecontainer('change', '#event-list-page');
});

remove script tag from ajax response data

i am working on a single page application using jQuery. whole html pages are sent as response to browser as ajax response.
$.post(url, function (data) {
$("#resp").html(data);
$("#resp").find("script").each(function (i) {
//alert($(this).text());
eval($(this).text());
});
});
how to remove script tags from data and than assign html to the div ?
the issue i am facing is the scripts that are written in the response page. they were not getting added to the DOM at first, so i used eval(), now the scripts are getting added twice in some situations.
The easiest way would be to use the .load() function with a fragment selector, since that will strip out <script> tags prior to updating content and result in them not being executed. If you're working with entire HTML pages though there may not be a suitable selector for you to use. However, I'd suggest trying this first:
$('#resp').load(url + ' body');
That would give you just the content between the <body> and </body> tags in the HTML page requested via AJAX.
If that doesn't work, I guess you could try manually stripping out <script> tags from the response prior to adding to the DOM:
$.post(url, function(data) {
var tempDiv = $('<div>').html(data).find('script').remove();
$('#resp').html(tempDiv.html());
});
That creates a new <div> element that isn't part of the document, sets its HTML to the returned HTML from the AJAX request, searches for <script> elements inside that, and then removes them. However, even though the element isn't part of the current document yet, the scripts may still end up being executed (I've never had a reason to do this so I haven't tested it).
with the help of Anthony's answer this is what i did to get it working :
$.post(url, function (data) {
var tempDiv = $('<div>').html(data);
var raw = $('<div>').html(data);
$(tempDiv).find("script").remove();
$("#resp").html(tempDiv.html());
$(scripts).find("script").each(function (i) {
//alert($(this).text());
eval($(this).text());
});
});
i could not understand why
var tempDiv = $('<div>').html(data).find('script').remove();
did'nt work though.

Scripts not running when using get function in jquery

I'm using the $.get() function to extract some data from my site. Everything works great however on one of the pages the information I need to extract is dynamically created and then inserted into a <div> tag.
So in the <script> tag, a function is run and then the data is inserted into <div id="infoContainer"></div>. I need to get the information from #infoContainer, however when I try to do so in the $.get() function, it just says it's empty. I have figured out that it is because the <script> tag is not being run. Is there another way to do this?
Edit:I am making a PhoneGap application for my site using jQuery to move content around so it's more streamlined for mobiles.
This is the code on my page:
$(document).ready(function () {
var embedTag = document.createElement("embed");
var infoContainer = document.getElementById("infoContainer");
if (infoContainer != null) {
embedTag.setAttribute("height", "139");
embedTag.setAttribute("width", "356");...other attributes
infoContainer.appendChild(embedTag);
});
});
As you can see, it puts content into the #infoContainer tag. However, when I try to extract info from that tag through the get function it shows it as empty.I have done the same to extract headings and it works great. All I can gather is the script tag is not firing.
This should provide you the contents of the element:
$('#infoContainer').html();
Maybe your script is executing before the DOM is loaded.
So if you are manipulating DOM elements you should wait till DOM is loaded to manipulate it. Alternately you can place your script tag at the end of your HTML document.
// These three are equivalent, choose one:
document.addEventListener('DOMContentLoaded', initializeOrWhatever);
$( initializeOrWhatever );
$.ready( initializeOrWhatever );
function initializeOrWhatever(){
// By the time this is called, the DOM is loaded and you can read/write to it
$.getJSON('/foo/', { myData: $('#myInput').val() }, onResponse);
function onResponse(res){
$(document).html('<h1>Hello '+res+'</h1>');
};
};
Otherwise... post more specifics and code
You have no ID to reference. Try setting one before you append
embedTag.setAttribute("id", "uniqueID");
It looks like you are wanting to use jQuery, but your example code has vanilla JavaScript. Your entire function can be simplified using the following jQuery (jsFiddle):
(function () {
var embedTag = $(document.createElement("embed"));
var infoContainer = $("#infoContainer");
if (infoContainer.length) {
embedTag.attr({"height": 139, "width": 356});
infoContainer.append(embedTag);
}
console.log(infoContainer.html()); // This gets you the contents of #infoContainer
})();
jQuery's .get() method is for sending GET requests to a server-side script. I don't think it does what you are wanting to do.

$(window).load(function()-how it works with FF

I have a jquery code.
$(window).load(function() {
document.title = $("#myid").text(); //not working in FF
});
Here I have used $(window).load(function() because in the #myid I am getting value through another javascript, if I use ready(), its giving me error. so I am first loading the window then start reading value.
Now in IE, after the window loads itself , I am getting the value of document.title,
but for FF its coming as blank.undefined.
Why? any idea or alternate sln.
It might be a rendering/timing issue.
How are you setting the #myid text? Im assuming you are running this code on page load?
Personaly on another note, i like to use the shorthand version of jQuery DOM ready, this might also fix your problem too.
jQuery(function(){
document.title = jQuery("#myid").text();
});
And i would make sure that you call it at the end of the body or ideally in the head tag.
I think it is possible that firefox triggers ready and load at the same time when it loads quickly (localhost, small experiment page with one div, etc.)
Why not put the title setting in the ready function right after getting it? If You put it in a div, You can put it in the title too.
I didn't check this code and it isn't a good way, but maybe it help you...
If your code isn't working in Firefox only, you can check browser by Javascript and execute my code for Firefox only.
<script type="text/javascript">
var timerId = 0;
function checkElement() {
// If don't work: try .html() or $("#myid").text() != undefined or smth like this
if($("#myid").text()) {
document.title = $("#myid").text();
clearInterval(timerId);
}
}
$(document).ready(function() {
timerId = setInterval('checkElement()', 500);
});
</script>
