Center Dynamic Content
Oct 16, 2006
I need to center (horizontally as well as vertically) a div on screen. It will be in front of everything else on the page and will include dynamic HTML content. (radio buttons, text input, etc.) Essentially it's an in-page popup. (Don't call me evil, this is for a game I'm making.) So far I can get FF to center it with this code:
function ShowBox(str,MsgBox){
MsgBox.innerHTML = str;
var style = gStyle(MsgBox,null);
var h = parseFloat(style.height);
var w = parseFloat(style.width);
MsgBox.style.left = (gWinWidth() - w) / 2 + "px";
MsgBox.style.top = (gWinHeight() - h) / 2 + "px";
MsgBox.style.display = "block";
}
Where gStyle is a cross-browser alias for getComputedStyle, str is the message I want displayed in the box, and MsgBox is the div that acts as the popup. Code:

I'm trying to get some thumbnail images that are displayed with ClueTip to be centered vertically & horizontally. The images are various sizes, though none is larger than 150px on a side, so I set ClueTip to have a width & height of 200px. The images are wrapped in a div so that I can have them display: none by default, yet assign display: block to the images themselves.
div.DownloadStatsThumb { display: none; vertical-align: middle; }
img.DownloadStatsThumb { display: block; margin: auto; }
The markup looks like so:
<a href="#" rel="#thumb_456" title="">foo</a>
<div class="DownloadStatsThumb" id="thumb_456">
<img src="/path/to/some/image.jpg"
width="150" height="101" alt="thumbnail image"
class="DownloadStatsThumb" />
</div>
The images are always aligned left & top. Eventually, I figured out that it was div#cluetip-inner that was the culprit. While the outer div has a height and width, the inner div has display:inline-block and so was shrinking down to the img size, essentially. I then added:
onActivate: function(e){
$('#cluetip-inner')
.css('display', 'block')
.css('width', '186px')
.css('height', '186px')
.css('vertical-align', 'middle')
.css('background-color', '#000');
return true;
}
The 186px is to avoid getting scrollbars and the BG color is to assure myself that it's resizing ok. However, the images remain centered horizontally only. Is there something else I've missed?

I am using xmlhttp.open();xmlhttp.send(); to send a php content to a div. This php content is again using the same method to get php content from a further page.The content of the div, does not seem to be using the css and javascript files defined in the calling pages <head> section.
Javascript file: scripts.js
client.php ----> loads data from: display_client.php
display_client.php ----> loads data from: display_brand.php

I'm working on an intranet. Target browser and mailclient are
IE6/Outlook2000.
I use a topframe because I want to mimic Excel's fixed columnheaders.
When scrolling long lists of data, the columnheaders in the topframe
remain visible. Displayed data is dynamic, using php.
Now my question:
I want to give my users the option of sending the content of frame[main]
to a collegue by clicking a button. I'm looking for a clientside solution
because I want this action recorded in Outlook's "Sent" folder. Server
side is not an option.
Apparently IE allows sending a html page through mail. But as I use
frames, the sent html page is empty. OnClick-ed, I assume I'll have to do a .focus to the correct frame, and then the incantation that IE uses to mail a htmlpage.

I am working on a little project I'd like to call post database and I got a little problem. when user clicks a page number, I bring html content from server and add it to page. And I can see the new content on the page. But if new html content has some java script it does not run. you can see the example on [URL]go to tutorials page, and click page 3 . new page will come. including following alert inside
alert('asdf');
But it show alert window. Somehow browser does not fire javascripts. Here is my guess: it does not work because you can not use javascript to shape pages after page load.(I just made that up. but there is no other logical explanation I can come up with.)

I have a div that is filled with content dynamically and is fixed so it will always be in the same place even when you scroll. I need scrollbars to appear when the div is has too much content and goes beyond the screenborder.

basically I have the following code:
<a href = "javascript:void(0)" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display ='block'">View Availability</a>
This pops up a divs with a black alpha background, so that it appears the new content is displaying over the top of the current content. This all works fine, however the content I am displaying in the top level div is (or should be) dynamic.In order for the content to be useful I need to grab the id.Normally I would simply do this:
<a href = "url.php?uniqueidentifier=<?php echo $row['id'];?>" onclick = "document.getElementById('light').style.display='block';document.getElementById('fade').style.display ='block'">View Availability</a>
However what happens in this instance is that the page loads with the javascript and the id in the url but it then disappears...

I am encountering this problem with Firefox, but no problem in IE. I have in a hidden <div> dynamically generated select options intended for re-use by dynamically created forms on page.
For Example:
<div>
<option value="1">xxx</option>
</div>
With javascript, when I use getElementById() to get the <div>, and then get the innerHTML, on IE I get the content just as they were generated out, and I was able to put this into an empty <select> and everything works. But when I try the same in Firefox, the innerHTML returns only the text part of the content. The "<option value="1">" part has been stripped off. Wondering if there's a solution to get around this?

I'm working on a form that I can add additional fields to dynamically (select fields and text input fields). I do so by clicking a button, which calls a javascript function, which in turn adds elements to the DOM. However, only the hardcoded (non-javascript created) fields are being POSTed. I assume this might have to do with the fact that the form uses tables to lay the fields out. The basic structure is similar to below:

I am new to jQuery and not an experienced programmer. I downloaded the accordion widget and it works fine. I have one small problem: the content box instances 2 and3 onwards, seem to be sizing themselves depthwise to the size of the first content box and not dynamically to the number of lines of text I enter in each. Can I make it dynamic with alterations to the CSS? If so whichproperty do I alter and to what?

I'm attempting to print a column of links received via AJAX request with an accompanying simple hover effect, however I can not get the hover effect to apply to the dynamic content. I've tried a few different ways of accomplishing this, none of which have worked so far. The most recent is posted below.
The call to imgUpdate.php in the following code snip returns content like:
<a class='storyImage' href='http://link.com/dev/?p=50'><img src='http://link.com/img1.JPG'/></a><br />
<a class='storyImage' href='http://link.com/dev/?p=47'><img src='http://link.com/img2.JPG'/></a><br />

I am using jquery.autoheight.js [URL] to adjust the height of the iframe according to content.
It works fine for the static content while loading. If I try to use the content with expand/collapse or display some content dynamically, its not adjusting according to the new content.

Okay I have a blank html page with the following in the head:
$(document).ready(function () {
$.ajax({
url: 'include.html',
success: function(data){
[Code]....
My question is why isn't this working? that it's probablybecauseit's been loaded dynamically andif ($('#load').length) is not checking dynamic content - but how would Iamendthe if statement to also check dynamic content?

I'm new to javascript and still trying to learn my way around. Below is my code
<script type ="text/javascript">
var a1 = "2";
var t2 = "hello world";
var total = ("t" + a1);
alert(total);
</script>
That code will display the string "t2" rather than the value of the variable t2. How do I make javascript display the value of the variable rather than the string?

I would like to build an HTML page that has four content areas. The first with 3 links that when clicked chage what is shown in the other 3 - and so changing the default content in these sections. The content for these sections will be contained in seperate HTML files sitting on the same server.
I understand this can be done without refreshing the page and believe JavaScript and Ajax is the best method to do this. Any advice?

I'm sure some wizard will tell me this is a classic example of "piece of cake"; in which case I bow and promise to listen In case I've struck granite rock, feel free to throw questions my way and I'll tell you if I've tried it or not.
I have a file, main.php (I know this is the JS-forum, bear with me). It outputs HTML and inline Javascript functions. When the user clicks on a graphical "tab", that tab is activated, and an ajax call is made to fetch.php with some specific parameters. Once the ajax request has completed, a given innerHTML container on the now active tab is filled with the stuff that fetch.php outputs.
So far so good.
The problem is that the stuff that fetch.php outputs is partial pure HTML and partial inline javascript. And this is where it gets tricky. If I declare an inline javascript function in the returned data, Firefox (and I suspect MSIE) refuses to understand that the function is there. It simply doesn't exist (!).
Using the Web Developer add-on for Firefox, there's an option to look at "Source code" and "Generated source code". The output from these two differ in that when I view the "Generated source code", I see the dynamically inserted javascript/HTML from fetch.php, whereas viewing "just" the source doesn't.
What did I do wrong? How do I get the browser to find/accept/activate the javascript code/functions that were inserted dynamically? I cannot put them in a .js file and include it, since they need to be dynamically created, and I cannot use eval() since that executes javascript "as is", in which a function will not be executed unless called.

Trying to get this code to work:
<script type=�text/javascript�>
function resizeframe()
{
var ff = parent.document.getElementById ?

As you can see, all I want it to do is set the frame row's height based on its content.

Does anyone know of how I could dynamically resize an iframe based on
the content's height (for IE) so that no scrollbar appears for the iframe?
The content will be from a different domain. I have searched on the web and
have seen solution like this
<script>
function resize() {
var oframe = document.getElementById("frameID");
//***
//var odoc = oframe.document; //(1)
var odoc = oframe.Document; //(2)
var obody = odoc.body;
oframe.height = obody.scrollHeight;
}
</script>
The html :
<iframe onload="resize()" src=http://different.comain.content border="0"
....... > </iframe>
I have seen 2 solutions on the web, the only difference being lines (1) and
(2) get substitued.
My browser is version IE 6.
It seems that the solution with line (2) works perfectly when the content is
from the same domain but gets a Permission Error if the domain is different.
When the content is from a different domain solution (1) does not give
Permission error, but instead the scrollHeight is significantly smaller
than the actual content. Even if the content is from the same domain it
still gives the wrong size.
So my question is
1) What is the difference between oframe.document and oframe.Document, why
does it give different results?
2) More importantly, how can I dynamically adjust the iframe size based on
the content height from a different domain?
