Dynamically Change The Font Family Of The Loaded Html Page Of The Main Page?
Nov 4, 2010
On my webpage, I dynamically create an iFrame when a button is pressed, then load a html page from within my own domain into the iframe, based on what html page is loaded into a variable. My question is, can I dynamically change the font family of the loaded html page from the javascript of the main page? My code to create the iframe is:
function setSubTxt(){
var par = document.getElementById('parentDiv');
par.innerHTML = '<iframe src="'+subTxt+'" style="width: 375px; position: fixed; height: 365px; left: 400px; top: 145px; border=none;" name="subIframe" frameBorder=0></iframe>';
frames['subIframe'].window.location=subTxt;
document.subIframe.document.body.style.fontFamily = "Arial";
[Code]....
the variable "subTxt" has the url of the html page to be loaded (always on the same domain). The code: document.subIframe.document.body.style.fontFamily = "Arial"; was my attempt to dynamically change the font, but it didn't work. Also, it should be noted that there is no font family set in the html pages which would override this.

I've seen dozens of scripts, some in javascript, some in php, that will allow you to do one or the other. Has anyone run across a script that has three buttons/images/links that will let you increase the font size, decrease the font size and switch font families? Either JS or php will suffice.

When I send a form from html to a function in javascript via a button I want to write the values of the html form on the screen. I do so by using the document.write() in javascript. This removes the page with the html form (input boxes etc) and then the only thing displayed is the stuff written by javascript. And the font family I had in the html part is now gone! Only problem is that I want to change the font family (like Times New Roman, Arial Black etc). I have very many document.write()'s, so would be swell if there were something that made me change the entire script's font family!

I'm trying to add dynamically generated HTML after the page has loaded. I've tried two versions.The latest versions is this, using insertBefore (as appendChild is buggy in a few browsers according to the SitePoint reference) ...
Code:
addImageField: function(x) {
var newNode = createImageField(x);
var src = document.getElementById("imageUploads");
[code]...
The first alert returns: object HTMLFieldsetElement .The second alert returns: object HTMLDivElement....and the third alert fails to fire, indicating a problem with the code above.Note that if I change the problem line to remove the null reference it still doesn't work (again the third alert won't fire):
Code:
scr.parentNode.insertBefore(newNode,src);

I am working on a page that will load in other pages using AJAX and the .html method. Something like this :
<span id = "edit">Edit</span>
<div id = "cont">
</div>
//the click edit script
[Code]....
Unfortunately this does not seem to work, entirely. It does trigger the click event but it messes up the post for some reason. I have played around with it for the last 45 minutes or so and it seems like the click event trigger is what is messing things up, if I comment it out it works fine. Could anyone tell me why they think this is? note this is an over simplified version of my actual code, but the structure is the same.

I am trying to get and then optionally update the font-family in CSS where I have:
<link href="css/header.css" rel="stylesheet" type="text/css" />
<link href="css/page.css" rel="stylesheet" type="text/css" />
<link href="css/footer.css" rel="stylesheet" type="text/css" />
and content in them like:
@font-face {
font-family: "AlphaMacAOE";
src: url('/fonts/AlphaMacAOE.ttf');
}
and dynamically change the .ttf to .eot depending on the browser. I am struggling to find a way to do this with JavaScript. I have tried:
x =document.getElementsByTagName('font-face');
document.write("x="+x.length+"<br>");
But it x is = 0 and I can't find any other way of accessing the src:url

I am currently trying to use Javascript to dynamically resize a navigation div (that is present on every page) according to the size of the main content div.
I am currently using the following code;
Code:
This works the first time I go to the site and if I refresh a page. However, if I use my on site navigation to switch between pages the div simply uses the height variable defined within my CSS (this needs to be here for users with JS disabled)
Does anybody have any ideas on what the problem might be. It's as if the script is only executed the first time any page on the site is loaded, but then not again.

I am in a bit of a rut in the self-teaching with JS. I am trying to get links to change the external js file currently on the main page without reloading, the external files are basically long document.write sections with a few interactive functions.
The closest I have found for help with this so far is a rotating script, but I want a manual change from a link (button, image, etc) instead of timeOut rotation. I am not sure what I need to do for the links to replace the timeout function to change the dynamic section.

OK, I am very new to jQuery so bare with me here. I am trying to get the document body height and set it as the height of a table, after the page has been loaded. Below is an example of what I am trying to do.
[Code]...
I am not sure where to place the jQuery code, before or after the table tag...and I am not even sure if any of my jQuery code is correct. Once again, i need to set the table height AFTER the document has been loaded and then dynamically change the height of the table.

I've been trying to get this page working with dynamically loaded iframe sources passed by URL, but I can't seem to get it working.Here's the relavent code:
<script type="text/javascript">
function delineate(str) {
URL = str.indexOf("=") + 1;[code]...
I used the hidden form to change the url to text - advice from another website. I'm sure there are better ways to do it, but I'll explore them as soon as this thing actually works..The types are in a subfolder named types, as shown. The document.write was placed in as a debug helper, and it displays the proper file location of whatever I select with the combo box, but the iframe doesn't change it's src to the selected page! I've tired the last line of the last <script> with several different methods, none of them producing any effect whatsoever.

I assume you know about this code:
Code:
document.body.style.background = "url() fixed #000000";
where you can change all of the page's background attributes..I was wondering if there was a similar one for font so that I can change the face, size, and color of all font on the page at once (when the page loads)I want this code in javascript because I want the font style and the background color in my page generated instead of fixed

I am sure this question has been raised and answered before, but I can't seem to find an answer that works for me. I hope I will get an exact response here. Here's my issue - I have my index.html that has its own $(document).ready method and everything pretty much works within it. I am trying to dynamically load a page to replace part of index.html (let' say the #inner_content ID) -

I'm wracking my brain on this one.
After a html document loads in a browser,I want to be able to monitor
the page incase any content on it changes for any reason.
Is there a Javascript function with which I can track 'what has
changed' on the webpage .
This should be irrespective of the type of content on the html page
I have two example for you to ponder on:
Ex1:
-----
Say in an html document there are two select boxes s1 and s2.
The items list in s2 depends on selctions in s1 (page is not
refreshed..ie.. s2 is loaded through Ajax or sumthing)
So after the html page loads I need to get a notification whenever s2
is populated...
Ex2:
-------
Say ,in a html page,there's a link,Onclicking which a light pop-up
div is created with some text.
How can I capture the content of this dynamic pop-up?
In all this discussion,I'm not taking into account any particular
format of html...the html content can be anything.......I just need
to keep tracking if any content chages after the page loads...
Ideally I need to achieve this using javascript (client side
scripting)
How can I achieve this??

I have a single web page that loads several iframes. One of the iframe pages has to be logged in first. I have that taken care of but once the page is loaded I need to change the source to a link with in the page. My guess is I need something to execute the code like a onload or something. This is what Ive been trying to get to work but like I said a newb! code...

The project I am working on involves a flash piece that communicates with a iframe.Currently the flash piece just calls on javascript functions. I want the buttons in the flash piece to be able to change the src of the iframe.
<script type="text/javascript">
document.getElementById('video').setAttribute('src',address2);
function closeVideo() {

I doubt this is possible, but I have no idea what actually happens when a page loads, so I thought I would give it a shot...
if a js file that is loaded externally has parameters, is it possible to turn those parameters into variables, giving the user the option to select the variable's value after the page has loaded?
maybe a concrete example would be better...
in google maps, the api is loaded like this:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script>
but if you wanted to specify that you want the api to function in Spanish, you load it like this:
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=es"></script>
and that language=es is the one that I want to change. But I can't seem to make it into a variable on page load, like this:
<script type="text/javascript">
var lang="es";
</script>
<script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=lang"></script>
much less make it changeable once the page has loaded.
I have a feeling that this is a really dumb question, but can it be done without reloading the entire page?

I was wondering if there was an easy way to dump the html that gets generated after the page gets loaded to verify it's what I wanted and expected (I'd like to check out the source, not just the results).

I'm designing a web page, Having a banner on top, then a search option following it.There is a menu item list below it on to the left.And the content of the links of those menu item should get loaded in the center of the page.And a footer having some copyright info.All these are in div tags. The problem is when i click on any menu item it should be loaded in the center div tag.Ive tried using Iframes but there is a scrollbar coming only in that area of center div tag.I don't wan't this to happen.Based on the size of the html page to be loaded the div tag size should increase, and so the whole page.Have tried using Ajax but not working.

Our company own a lot of domains and want to put a short page of copy on each address along with keywords before redirecting the user to our main site. I have been able to get the page to load the main site after the desired time using this code in the head...
<META HTTP-EQUIV="refresh" CONTENT="40;URL=http://webaddress.com/">
That works perfectly, I am now trying to display a countdown timer from 40 seconds down to 0, and on 0 redirect the user. Saying something like "You will be redirected in XX seconds". Is there anyway of doing this? I've been searching google for the answers with no luck and can only seem to find timers that countdown to a set date.

I have a page that inserts a div after another div on my page. Basically this div and its content are generated by the server and outputted via Ajax when the user clicks a button.I have something like:
//Listener function
$("div").click( function () {
alert("thing");
});
Clicking any of the divs that were loaded on the page will give this alert however, clicking on this div that was inserted after the user clicks a button does not respond to this listener. I put my rendered html into the w3c validator and my page has no errors (because I thought that maybe I had a missing end tag which would cause jquery to not work).

I just need the first div to show then when you click on the <li> element the other div shoes. It works fine when the page loaded by istself. Here is my code:MAIN
PAGE:<

I have two problems that I suspect will be bread-and-butter problems for the
more experienced guys on here, but I'm not the greatest with js.
NB: Code snippets at the bottom
The first problem is that after a bit of fiddling I'm getting am 'Object
Expected' error when I click on the Depot dropdown which I can't seem to get
round. The code I had was working OK but then I cut it all out, tidied it
all up, and put it back in and now it doesnt work.
The second problem is a 'How do I...'. I'm using an XML data island to
retrieve some data without submitting the form. In the first example, when
the user selects a Customer, the Depot list is updated with all the depots
for that customer; This all works fine. What I want to do now is retrieve
some more data when the Depot is selected.
I have the XML bits working; the js code snippet correctly output a series
of msgboxes with the correct value in (or at least it did until I introduced
the Object Expect error!).
However, I'm unsure as to how to display this information on the page. The
XML contains a series of Part No's and Quantities, which I'd like to display
in a table towards the bottom of the screen. The problem is that I don't
know how to dynamically create and populate this table.
The only caveat is that I dont want to show the table if no values are
returned from the query....
