JavaScript - Page Centering Issue
I have an issue with my div visibility toggling
Code: function toggle_visibility(id) {
var e = document.getElementById(id);
if(e.style.display == 'block')
e.style.display = 'none';
else
e.style.display = 'block';
}
I call it from an image map he Code: <area shape="rect" coords="234,-12,480,203" href="#peripherala" onclick="toggle_visibility('peripherala');toggle_visibility('shadow');return false"/>
and I do the return false to stop the thing from jumping all over the place, but where i click next, the page scrolls down to center on that point, which is really annoying. How do I stop it? Thanks for any help.... Similar TutorialsI am in desperate need for help as I'm pulling my hair out! I'm pretty sure this is JavaScript related. I'm incorporating a WordPress header into Opencart. Its pretty basic. I copied the WordPress header source code into the header of the Opencart and all is well in Firefox & Chrome and Safari. In IE however...If you enter the product page through the categories on the left the product page left aligns and breaks...I can't figure this out for the life of me. I tried to debug it with explorers tools but I don't know enough about Java script to understand why its breaking. Can anyone PLEASE help me on this?!!! My site is http://www.sterlingportable.com/store/ I have two simple forms on the site, each captures an email address they are for two separate languages. However when I try to validate, only one validates and the other one doesn't Javascript: Code: <script type="text/javascript">
function checkform ( form )
{
// ** START **
if (form.email.value == "") {
alert( "Please enter your email address." );
form.email.focus();
return false ;
}
// ** END **
return true ;
}
</script>
<script type="text/javascript">
function checkform ( form )
{
// ** START **
if (form.email2.value == "") {
alert( "Please enter your email address." );
form.email2.focus();
return false ;
}
// ** END **
return true ;
}
</script>
Form 1- It Validates Just Fine Code: <form name="quote" method="post" action="contact.php" onsubmit="return checkform(this);">
<td>
<input name="email" style=" background-color:#FFFFFF; width:200px; height:13; font-size:11px; color:#666666" type="text" /></td>
<td> <input style="border:none" type="image" name="imageField" id="image" src="submit.jpg" />
</td>
</form>
Form2 Doesn't Validate Code: <form name="quote" method="post" action="contact.php" onsubmit="return checkform(this);">
<td><input name="email2" style=" background-color:#FFFFFF; width:200px; height:13; font-size:11px; color:#666666" type="text" /></td>
<td>
<input style="border:none" type="image" name="imageField2" id="image2" src="submit2.jpg" />
</td>
</form>
Hi all, I'm a bit newbie in scripting, but i'm trying to learn by myself . Hope you can help me with this I have two main pages, called index.html and news.html. Both pages loads a third page called news_content.html, using AJAX function load. This third page has a pagination script, but the pagination has to be different if the page has been loaded from index.html or news.html (for example, the max items per page has to be different). The pagination settings are defined inside news_content.html. How can I know, from the content page, with one has loaded it? Or... its possible to pass values from the main pages into the content page, in order to change the pagination settings? Thanks in advance! This script isnt working. Im not sure what im doing wrong. forgive me i havent programmed in javascript before. titles.js Code: <script type="text/javascript" language="javascript">
<!--//
function random_Title(){
if (parseInt(navigator.appVersion) >= 4) {
var num = 3;
var rantitle = new Array(num+1);
rantitle[1] = "Random Title1";
rantitle[2] = "Random Title1";
rantitle[3] = "Random Title1";
ranNumber = parseInt(num * Math.random() + 1);
document.title = rantitle[ranNumber];
}
//-->
}
</script>
html page Code: <html> <head> <script type='text/javascript' src='http://www.flashmajic.com/Google/titles.js'></script> <script> document.title = random_Title() ; </script> </head Good Morning Everyone, My first post here so hope i get the format right The problem I have a menu on a new website im developing. The menu is going to be within a PHP include file. I need a way of (using JS) the current page having its menu item with a different image to the others e.g. a "selected" image. The code im experimenting with, and which may shed a bit more light on what im trying to achieve is as follows: Code: var url = window.location.pathname;
var filename = url.substring(url.lastIndexOf('/')+1);
if (filename = 'about.php')
{
$('#about').attr('src', 'images/Nav/about_selected.png')
}
else
{
$('#about').attr('src', 'images/Nav/about_over.png')
}
I am using jQuery for this project thus the jQuery code being thrown in there. The logic of the code iv made is, IF the page is 'About' then the 'About' menu button should display 'about_selected.png'. I hope this makes sense and a solution would be much appreciated. Thanks! This has probably been asked times before, but i've tried a few things and im struggling a little. i just wanna center this slideshow which i got to code from http://www.javascriptkit.com Im was just getting the hang of CSS after a little knowledge of using HTML back in the myspace days, but now Javascript is making it a bit more challenging. I tried doing the < center > < / center > thing around it, which did move it but still kept a scroll bar at the bottom and was mroe right aligned if anything. Its from big cartel.

I'm trying to write a function to center a div within a parent div, and I'm having a little trouble. Horizontally, it works fine. Vertically, not so much. This is my function: Code: function centerObject(idName, idParent) {
var parentLeft = $(idParent).position().left;
var parentWidth = $(idParent).width();
var parentWCenter = parentWidth / 2;
var parentTop = $(idParent).position().top;
var parentHeight = $(idParent).height();
var parentHCenter = parentHeight / 2;
var objWidth = $(idName).width();
var objWCenter = parentLeft + parentWCenter - (objWidth / 2);
var objHeight = $(idName).height();
var objHCenter = Math.abs(parentTop + parentHCenter - (objHeight / 2) - 20);
$(idName).css({left:objWCenter,top:objHCenter});
};
The line with the Math.abs call is necessary because without it, the given div ends up halfway off the page up at the top. At least this way it appears somewhere within the browser. The divs in question are all set to position: absolute, but I've tried setting them to all the other possibilities without luck. Or maybe I missed something. This happens in any browser... IE, FF, Chrome, Safari, etc. In any case, anybody have any ideas on where I went wrong? Thanks! Rob Hey, ive been strugglng all day to centre a DIV with javascript in the centre of my page. Ive created a modal popup and id like it to stay in the screen even if the page has been scrolled down. And no matter what i try i cant get it to actually hit the centre of the screen. I should add that im totally new to javascript but decided i cant avoid learning javascript forever so here are my pathetic efforts.. Code: function ShowPopup(hoveritem, thepopup, theimage)
{
popVar = document.getElementById(thepopup);
//document.getElementById('hoverpopup').style.paddingLeft = screen.width/2-250;
//document.getElementById("hoverpopup").style.paddingTop = screen.height/2;
// Set position of hover-over popup
//popVar.style.top = hoveritem.offsetTop + 50;
//popVar.style.left = hoveritem.offsetLeft + 100;
// Set popup to visible
popVar.style.visibility = "Visible";
}
Ive tried loads of other things too, whats commented out has been my last effort. Im doing other things too in the function in case you wondered. But any ideas how i can do this, sorry if ive not been too clear! I have a problem in centering my popup window. I want it centered in the page when it pops up. The problem is in the code that is red. Here's a part of my script: if (counter == 0) { var myRes = "<html><head>\n"; myRes += "<title>Popup Window</title>\n"; myRes += "</head><body>\n"; myRes += "<div style='text-align:center'>\n"; myRes += "<p>Search character '<b>" + searchChar + "</b>' not found in text string!</p>\n"; myRes += "<input type='button' value='Close Window' onclick='window.close()'>\n"; myRes += "</div>\n"; myRes += "</body>\n</html>"; var popup = window.open("", "Popup", "top=10,left=300,width=300,height=100"); popup.focus(); popup.document.write(myRes); popup.document.close(); Hola! I'll give you a little background before I ask you guys my question! I have a Header, a rectangle of 800x100 and directly below that I have Spry Collabsible panels stacked on top of each other with my menu items 'Home' 'About us' etc. My question is... does anyone know of a way I could vertically center everything on the page, so that when the panels are closed it is nicely in the centre and when you open one, the header moves up to allow room for the content and the whole thing stays vertically centered on the page. I'm guessing this will need some kind of fancy javascript to make possible. Thanks in advance for any advice you can give! Adam Hi all, Here's the situation. A client has a 1440 wide flash move in .swf format that serves as in intro to the site. They want the flash movie centered on the screen even if the resolution is lower, at 1024 or whatever. At this point my idea is to wrap the flash object in a div and center that div using javascript so that it centers no matter the screen width, but I don't know exactly how to do this....any ideas? thanks very much. Hi guys, I don't know if this is possible at all, but I thought it was worth a shot asking. http://www.applicate.com.au/home I have a slideshow in a div that is 1800px wide, and a smaller content area which is 980px wide. Usually I would use a background image for this, but it needs to be a slideshow. It works great on larger screens, but not on small screens. I've removed the horizontal scrollbar, but when viewing on a small screen, obviously the content isn't in the center. I know centering this isn't possible in CSS, is it possible in JavaScript? Otherwise, I guess I'll look for a module that is a background image slideshow. Thanks in advance for any suggestions (: Hello. My goal is to load the JS for a specific element before displaying that element. I integrated a third part script, and it works well. I set the timer he The JS is in my heading as <script type="text/javascript" src="countdownpro.js"></script> About mid-body I have: <span id="countdown1">2010-07-20 00:00:00 GMT+00:00</span> which allows for the setting of a target date to countdown to. When the page first loads it shows the above long format target time, until the js/meta tags kick in to modify it to just show the actual countdown as 00:00:00. I have attached countdownpro.js to this post. I tried shifting the function CD_Init() to the top of the script, and also appended it inline with the .html. I tried setting the big external script to "defer", but neither arrangement worked. I also tried placing the src file right at the top. I appreciate your help. I just wrote an essay to discover it had logged me out and I lost everything. Grrrrrrr. Here goes again, simplified this time. I've got a sticky footer at the bottom of the page and a spry collapsible panel which expands to reveal content on mouse over. The problem I'm facing is that the page doesn't scroll down with it, only the scroll bar gets larger to accommodate for a manual scroll down. This is kind of useless because the user might not even realise that there's extra content there in the first place if it's not automatic. My question is, what's the best javascript code to use to automatically scroll the page down when the spry tab is opened and where would I insert it? I've tried all morning with no success so far! Thanks, Nick, I'm copy pasting this post this time round, I don't trust this website now I want to implement a javascript function where a submit button will be submitted from the parent page each time I close a child page. Please let me know what I did wrong in my code and please elaborate your answer so that I could understand it better. Thank you so much for your help. I have the following jscript code but it is now working. Code: window.onunload = submitParent;
function submitParent()
{
var doc = window.opener.document,
theForm = doc.getElementById("finalForm");
theField = doc.getElementById("finalSelected");
theForm.submit();
theField.trigger('click');
}
My form from the parent page is as follow. I want my jscript to just click on the submit button once. Code: <form id = "finalForm "name= "finalForm" method="POST" action=""> <input type="Submit" id = "finalSelected" name="finalSelected"/> Hi, I am Aditya. I am explaining below the exact scenario where I need the help: I am developing a web application in which I need to integrate a javascript/html editor on some of the web pages and then provide 'Edit' buttons on those web pages so that users can edit the content on that partciular html/jsp page (like editing in wiki pages) and then, when they add some content and click on submit button, the new content should appear on the web page with all the formatting (i.e. bold, italics, color and so on) which was applied by user when he was entering the text. Now, I need help for the below issues: 1. Please suggest me a good javascript/html editor (freely downloadable) which I can use to integrate with my web pages. 2. Once the user has entered some content using the above javascript editor, how to make that content reach the server and update the corresponding web page. I am new to web development, so may be that these questions are too simple. But, I need some help from you. Waiting for your reply, Thanks, Aditya Hi there! I am using GlassBox "http://www.glassbox-js.com/" As a light box on a website. Basically, You click an thumbnail image, and a window pops up with a larger version of that image. Now originally, the window opened X number of pixels from the top of the page. However, My thumbnail images were located mid page, so when you clicked on one, the window would open at the top of the page and the user would not see it unless they scrolled up. So I attempted to modify the script so that it would get the users page width/height and display it directly in the center no matter the position. Now my problem is that the script only works when the user has already scrolled down. So if the page is scrolled all the way to the top, and you click on a thumbnail, the window will not open center screen. Here is an example: http://synaxis.pcriot.com/ When the page loads, DO NOT scroll it, and click on the image. You will see the window pop up, and not centered, like it should be. However, now if you scroll down, and click the image again, you see that it is now centered. I also noticed that when the page is scrolled up, and the image does not center, it always is placed below the thumbnail image, or otherwise where ever the DIV is located. It normally located under the image, but if i place the DIV at the top of the page then the window will pop up there. And this does happen on every browser that I have tested, Firefox, IE, and Chrome. So, I am pretty much stumped as to why this is happening. If anyone can shed some light I would be very grateful. Thank You Here is a link to the original code: http://synaxis.pcriot.com/javascript...ox/glassbox.js And modified code: http://synaxis.pcriot.com/javascript...ox/glassbox.js The modified code is at the very bottom of the script. Original Code: Code: /**
* @public
*/
if ( typeof($) == 'undefined' ) {
$ = function (id) {
return document.getElementById(id);
}
}
Modified Code Code: /**
* @private
*/
var removeElement = function(id) {
var Node = document.getElementById(id);
Node.parentNode.removeChild(Node);
}
/**

var getDocHeight = function() {
var db = document.body;
var ddE = document.documentElement;
return Math.max(
db.scrollHeight, db.offsetHeight, db.clientHeight,
ddE.scrollHeight, ddE.offsetHeight, ddE.clientHeight
);

Thanks Hi there, Im a total newbie and learning html and javascript as I go along, so any help you can give is greatly appreciated! It is possible to perform a find in page search that looks at a specific link, opens the page in a new window and finds the text within that document?? Basically I regularly use an html page in work that has a list of people and their telephone numbers. I want to be able to type in a searchbox on my main page and it open the target page and find the name I am looking for? Is this possible or can you only Find In Page on the same page or another frame? Tearing my hair out........ Thanks Glen |
