I use the tabber script shown on http://www.barelyfitz.com/projects/tabber/ to provide a tabbed page. Generally it works well, and my only complaint is that the tabs don't show until the content has fully loaded, and then there is a jump as the screen writes itself properly. (See www.littlehotels.co.uk/spain/noves.php for an example of what I mean.)
I thought the solution would be to hide the div containing all the tabbed content like this
<div class="tabber" id="tabber" style="display:none">
and then reveal it with a small javascript function which is called by
<body onLoad="ShowTabber()">
The javascript itself is
<script type="text/javascript">
function ShowTabber() {
document.getElementById('tabber').style.display = "block";
}
</script>
My little function appears to stop the external javascript (tabber.js) from working because the page displays the content of all the tabs in line, without the the tabs themselves at the top. This is the same result as if I delete the reference to the external script from the of the page.
What am I doing wrong?
More explanation:
When the tabber.js file is missing, the page displays the content of all the tabs one after the other(as you would expect). Running the script as explained above has exactly the same effect; hence I am concluding that the script blocks the main javascript from running.
'onLoad': function(argsObj) {
/* Display an alert only after tab */
if (argsObj.tabber.id == 'tab') {
alert('Finished loading tab!');
}
}
By default select a tab.Then after completion loading that tab it will show a message.

Well, I solved the problem (sort of) with jQuery, but it has now raised another problem.
In response to PSR, I looked more deeply into jQuery. It would have been too complicated to change over to .tabs(), but I did use jQuery to hide and show some divs at the appropriate moments.
I placed a simple little line in fron of the tabber div to show a "Loading" message.
<div id="loading" align="center" style="position:relative;top:70px"><h6>Loading ...</h6></div>
Then I put this script in the head, under the jQuery line.
<script type="text/javascript">
$(document).ready(function(){
$("#tabber").hide();
$("#loading").hide();
$("#loading").fadeIn(1000);
});
$(window).load(function(){
$("#loading").hide();
$("#tabber").fadeIn(300);
});
function checkResize(id){
var win=document.getElementById(id).contentWindow.document.body.scrollHeight;
alert(win);
}
</script>
That works fine, but a couple of the tabs have iframes for their content, and this script breaks autoResize script I use on those iframes. I'll open a new question to see if anyone has an answer to that.

I'm trying to create a basic Chrome Extension that comes up with some kind of alert when the extension is clicked. I was able to create this using the following Javascript:
function spoilerAlert() {
confirm('Warning, there are spoilers on this page!');
}
document.addEventListener('DOMContentLoaded', spoilerAlert())
and then adding the following to my HTML file:
<body onload = 'spoilerAlert()'>
whilst also referencing the .js file in the body:
<script language='javascript' src='popup.js'></script>
This works, but since the extension icon is in the corner of chrome, when it is clicked the alert box appears in the top corner of my browser, mostly off screen:
This box can be moved but obviously this is not ideal. After extensive googling it appears that the positioning of these built in alerts cannot be changed, and everywhere suggests using a customised dialogue box. So I have been trying to use a modal (which seems to be more appropriate for what I want to achieve in the long run which is considerably more complicated than where I am up to currently), but applying the same logic as before does not seem to work with modals. I have changed the Javascript is the following:
var modal = document.getElementById('myModal');
function spoilerAlert() {
modal.style.display = "block";
}
document.addEventListener('DOMContentLoaded', spoilerAlert())
and in the HTML file I have:
<body onload = 'spoilerAlert()'>
<div id='myModal' class='modal'>
<div class="modal-content">
<p> Spoiler Alert </p>
</div>
</div>
</body>
I also have some styling in the head. However the HTML no longer seems to be reading the Javascript, is ignoring all of the styling and is simply giving me this:
which seems to be the complete default. Any suggestions on how to get my HTML to read the modal functions in my Javascript file would be appreciated, or any other easier ways to create a custom dialogue box. Please note my Javascript knowledge is limited! Thanks.
i have a problem here
i make a page that have function for print page that contain of dynamic table. the print function method is open the page html that contain the dynamic table in the new tab then open the print dialog. the process going well but when i add the ajax call for displaying the data in the dynamic table. the data not displayed at the table in the print dialog..but when i cancel the print dialog and the page that must be printed show off the data is displaying there...
how to fix it.
this the picture of the page
i use this code for print that
<script>
function myFunction() {
window.open('SPL.html','','height=650,width=1200').print();
}
</script>
You didnt provided yet the code of your generator, so I simply explain you why its not working and what you can do.
A good reference for window Mozilla Window Open
You can read there more details about possible functions and more. Your problem is, with:
window.open('SPL.html','','height=650,width=1200').print();
Directly after opening the file you call the print function, at this moment your script and ajax request don´t have finished yet. Thats why it just shows you the current state with the predefined html and css code.
So what you have to do is simply call print after it has finished. There are tons of ways to achieve this.
The simplest way would it to open it like this:
window.open('SPL.html','','height=650,width=1200')
Inside your SPL.html you stack your js script inside:
$(document).ready() {
//Your Generator
}
This little piece keeps safe that all dependencys (external scripts and dom elements) are created before your generator runs and it gives us the possibility for the next function:
$(window).load(function(){
window.print()
});
This one is a version of the globalEventHandler window.onload. It basicly ,if you read the documentation, fires after everything is loaded, including images, frames, objects and so on. And the tricky part also after document.ready, this makes it sure that our generator is finished before we run the print command.
I hope this helps, If you really want to stick the print command inside your first page I can give you an example of this too. But it is not as bullet prove as this solution. Ah and if you want to stick with #Saurabh solution you have to use allow-modals for your Iframe, if not it wouldn´t be possible to print. Is also mentioned in the official documentation.
This issue is caused because the page is not completely loaded before calling the print function.
Update: Using jQuery
index.html
<html>
<head>
<script src="http://code.jquery.com/jquery-1.4.3.min.js"></script>
<script>
$(document).ready(function(){
$('#loaderFrame').load(function(){
var w = (this.contentWindow || this.contentDocument.defaultView);
w.print();
});
$('#loaderFrame').attr('src', 'SPL.html');
});
});
</script>
<style>
#loaderFrame{
visibility: hidden;
height: 1px;
width: 1px;
}
</style>
</head>
<body>
<iframe id="loaderFrame" ></iframe>
</body>
</html>
I am developing in an older apploication using JSP and Frames for HTML. I call my JSP by clicking a link in a toolbar. On the called page I have some information and everything is working fine. However, I also have some hidden information which is shown by clicking a button on the page and thereby calling a JavaScript function for it to be shown. When calling this function, however, the information is 'presented' at the bottom 'outside' of the page and no scroll bar is visible. If I then click the link in my toolbar to 'reload' the page there is a scrollbar visible. This, I believe, is because I have the following JavaScript in the body onLoad=document.body.scrollTop=document.forms[0].scrollPos.value;
I have tried to reload the JSP inside my JavaScript with the window.location.reload(); & parent.location.reload(); but this causes a warning to be shown (if you are performing transactions make sure blablabla).
This is how I call my JSP from the menu:
<frameset border="0" cols="100%" rows="100%">
<frame name="eoPartInfoHeader" src="/glopps/processEoPartInfo.do?method=initializeForm" noresize="noresize">
</frameset>
This is body on called JSP:
<body onLoad="setTitle('<bean:message key="title.eoPartInfo"/>');document.forms[0].jump.selectedIndex=0;setFocus();document.body.scrollTop=document.forms[0].scrollPos.value;">
Error should be kind of similar to these questions:
Scrollbar not visible in iframe
scrollbar in jsp with window.open
SOLVED
If anyone ever reads this here's how I solved it. Turns out we had a JavaScript function in another JSP which looks like this:
function setScrollbar() {
if(document.body.scrollHeight > document.body.clientHeight){
document.body.scroll="yes";
}
else{
document.body.scroll="no";
}
}
Then that function is justed called on body load:
<body onLoad=setScrollbar();">
When my Bootstrap Modal Window is open, I have been unable to stop background scrolling from the main page. I followed the directions given in this StackOverflow question, but I have been unsuccessful so far: Prevent BODY from scrolling when a modal is opened
On the left side, near top of this page, after it loads, you will see a button that says "Large Modal". If you click it, it will open a modal window. After its open, if you scroll up and down, you will see the background moving.
http://gettinmobile.com/home.html
I have added the CSS as directed in the stackoverflow question I linked to above:
body.modal-open {
overflow: hidden;
}
I have added the javascript shown on the same stackoverflow question, though I am not sure this is done correctly:
<script type='text/javascript'>
$("#myModal").on("show", function () {
$("body").addClass("modal-open");
}).on("hidden", function () {
$("body").removeClass("modal-open")
});
</script>
Any help would be appreciated, maybe someone can see what I'm doing wrong... thanks!
You need to wait for jQuery to finish loading before you start binding events. You can do this most simply with an anonymous function:
$(function(){
// YOUR CURRENT JS CODE HERE
});
in your JS code at the bottom of page, try replacing the "$" sign with "jQuery" (no quotes), and see if that helps, it's a common happening in WordPress and quite likely the root of your problem
I am having a pretty strange problem with a website I am messing around with, and I can't wrap my head around what may be going wrong. I am using PJAX on the site, and the have a div in my body with the id of #page-contents.
The code I am using to setup PJAX is as follows...
<script type="text/javascript">
$(function(){
$(document).pjax('a', '#page-contents', {
fragment: '#page-contents',
timeout: 2000
});
});
</script>
I know that the setup is correct because I edited the PJAX file to fire an alert whenever it swapped out the content of my #page-contents div, and I do see that alert when I would expect to (i.e., on link clicks).
I have a navbar along the top (a bootstrap navbar) and I was initially having trouble keeping track of which navbar item would be marked as active. I have solved this problem using the following javascript code.
<script type="text/javascript">
$("a").click(function() {
$(".navbar-nav li").removeClass("active");
var nextPage = $(this).attr("href");
nextPage = nextPage.substring(nextPage.indexOf(window.location.hostname) + window.location.hostname.length);
switch(true) {
case nextPage == "/about":
$("#about-nav").addClass("active");
break;
case nextPage == "/contact":
$("#contact-nav").addClass("active");
break;
case nextPage == "/resume":
$("#resume-nav").addClass("active");
break;
case nextPage.indexOf("/projects") != -1:
$("#projects-nav").addClass("active");
break;
default:
break;
}
});
</script>
This works fine for all links I have in my navbar, but I have found that any links I have inside my #page-contents div will not trigger my above script. I know that PJAX is still working as the page changes and the alert I inserted displays.
A few things I have found in my own testing:
I have also found that if I directly load an address that contains a non-navbar link and then click that link, it will work. But coming back to that page via a pjax reload and then clicking the link will not fire my event.
Adding a test class to one of my anchors and then associating some event with that class has the same problems.
Does anybody know why my script would not be getting executing? Or maybe I am just missing something obvious.
Thank you in advance!
P.S.: The website in question is my personal site I am working on, the link is http://rosshays.me, the page I first noticed this on was my about page. (The site is a work in progress as you'll clearly see.) As mentioned about, going to the about page directly and clicking the link will work, but if you navigate to the about page and then try to click the link in the page, it will not work.
Ross-
I had a similar issue and I know how to solve this; this script is not binding to the new elements because it is not being re-ran on the new elements once they are loaded.
Please put your function in an external .js file. Once complete, you can add this script to your header:
$(document).on('pjax:complete', function() {
$.ajaxSetup({ cache: true});
$.getScript("YOUR SCRIPT FILE PATH HERE', true);?>");
});
You will have to add more $.getScript calls for any other javascript/jQuery that is needed in order to enable the events you want to take place. (Example: you may need to reload jQuery)
This will re-apply the jquery and javascript to the new elements that are loaded via PJAX.
*One thing to note: If you are using twitter bootstrap, do not re-call the bootstrap script with $.getScript as it will cancel itself out on every other re-load.
