Finding A Code To Get Height Variable?
Mar 23, 2010
I have a iframe element which currently has a small amount of javascript that handles the scrolltop and I am trying to add a variable to that which controls the height of the iframe based on the source height. I do not want to set the height of the iframe in CSS because if I use this same method for other iframes and the source height is not the same it will not work.The page with the iframe is here (click on the link on the top of the page to load the iframe):
[URL]
The page I want to load into the iframe is here:
[URL]
The javascript and html for the parent page is:
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
[code]...
Again, what I need is for the iframe to get the document height from the page that will load into the iframe and then have the iframe height be that exact size. As you can see once you click on the link it is much shorter than the page I am using to load into the iframe.I do not know javascript enough to figure it out and have spent a couple days looking all over the internet and have yet to find something I can incorporate into the javascript I already have.

I want to be able to find the height of a div in pixels without defining it in JavaScript. The Div needs to be able to have whatever content in it is required, and it will change without a refresh. I have no idea what could possibly do this, I was hoping somebody with more experience with JavaScript could help me :D
It also really needs to be at least Internet Explorer, Firefox and Opera proof.

We have a js heavy web-ui. In the production environment it runs minimized, composed from 10 or so js files. When we have a js-error of some sort (we have about 100 users and growing) we write the window.onerror information to a database. Only, it is not very helpful since linenumbers mean nothing in the intelligeble code.
Is there a minifier that tags the result that would allow translation of linenumbers? Is there some other method people use to solve this problem?

Basically I have a div id 'register_stretcher' and within this divI have a dropdown select control. If the user chooses the option 'Other', the 'Other' text input field appears. For this to display correctly the 'register_stretcher' div needs to be extended in height by 30px. What I do first of all is get the initial height of the 'register_stretcher' div (this is created dynamically). then depending on what option is selected by the user, the div is resized accordingly. Not surewhat I have done wrong here:
jQuery(document).ready(function(){
orig_height=jQuery("#register_stretcher").height();
});
jQuery('#visit_source').change(function(){
if(jQuery(this).val() === "other"){
jQuery("#register_stretcher").height(orig_height+30);
jQuery("#other_reason_label").show();
[Code]...
Works in Firefox/Chrome but not IE7/8. In IE it seems to not get the value of orig_height.

I am working on outlet pages of an online store.There are 4 products displayed on each row.On that store, products are displayed with images,product name, model no., price and buttons.For some products, the name is longer, for some price is longer.I am using <td> for displaying each information.The problem is - the height of the name's <td> and price's <td> are different for different products.I want a JS code which can detect the biggest height (for each row separately) from both the above td's separately and assign the maximum height to the corresponding 3 td's of that row.This should be done for each row separately.note : I an right now using this code - But it takes the height of both td's for 1st product only and assign it to all the products.
<script type="text/javascript" language="javascript">
var ht1 = document.getElementById("name_td1").offsetHeight;
document.getElementById("name_td1").style.height = ht1;

I've been struggling with implementing Jquery into my navigation menu. The menu itself is an unordered list with subitems. The subitems appear next to the main menuitems (for showing, hiding and append classes to these items I use the 'collapsor'-plugin). So far so good...

Code:
$('.openDialog').click(function(event){
var width=$(this).attr('width');
var height=$(this).attr('height');
[code]...
I'm trying to do something like above, where I pass the width and height into the Dialog box but it doesn't take the variable.It only works if I put an actual number here instead of a variable.
$('#dialog').dialog('option', 'width', width);

I have a DIV menu bar that I want to stretch 100% in height. It worked perfectly fine until I added the XHTML doctype. So I tried absolute positioning which worked but then my other divs started overlapping them.So I want to know if there is any javascript code to make my menu bar stretch vertically. The name of the div I want to stretch is the class "sidemenu".

html {
height: 100%;[code]......

I want to load an html div in a variable, modify it in another variable; and then change the document injecting the contents.
1. I load the html to be changed in a variable (code)
2. I modify an attribute of <param> using attr() and I put the result in a var (newcode)
3. I change the html in the doc
I've used the debugger, and all steps give the expected results, except of newcode.html(), which is a null string. Why?

I've got an IFRAME it loads a page with variable contents. I need to know the WIDTH of the body of that page. I'm using offsetWidth and offsetHeight
Quote:
This is weird....offsetHeight returns the height of the document body. offsetWidth returns the width of the iframe!

When I try to substitute the the number 1 with the variable scr_val it does not work. This works:
Code:
if(document.course.frm_score_front1.value != '' && document.course.frm_score_front1.value > parseInt(num_over))
{document.course.adj_score_front1.value = parseInt(num_over);}else{document.course.adj_score_front1.value = '';}
This does not:
Code:
var ct_val=1;
if(document.course.frm_score_front1.value != '' && document.course.frm_score_front1.value > parseInt(num_over))
{document.course.adj_score_front+ct_val.value = parseInt(num_over);}else{document.course.adj_score_front1.value = '';}

I had to maintain older javascript code with some jQuery addons / plugins (I guess also old ones).
Today I found this:
I looked into the api documentation I found some days ago also ".height()"
As I understood that code like this: "jQuery.fn.height" will overwrite the current "height" methode in jQuery.
Is this right? And why the code in line 1 (see above).
I want to remove old javascript code, and also the code above. I found similar code snippets where all the jQuery function on this page [url] will be overridden. And also for "scrollLeft", "scrollTop", "offset".
The incode documentation in the old js-code says also something about "Plugins/Dimensions".
Can I remove the code, because it is old code for a jQuery version where the "height" is not implemented?

I have this layout
And then I have this code to determine the cell height.
So basically I need both my first and last cells to be able to have the mainbody cells height, but that code only works when placed in or after the cell being measured, in this case "mainbody", my question is this, is their a way to get the size of the mainbody cell before its done loading somehow?

I would like to know if it is possible to insert workable javascript
code into a variable. For example, in php if I say
<? echo $blah; ?> and $blah equals " ?> <script>
top.navi.document.title </script> <?"
I would want the page to act out the code when i tell it to echo the
variable.
If this is not possible, is there a way to set information from
javascript into a php variable?
Also, i would like to know how to use if statements in javascript. For
example, if I have a variable x and i want to see if x equals "test"
and if it does then it caries out some code.

I use 'div id' as a variable for some code I'm working on. The idea is that depending on what 'div' the user clicks on the variable will change as according to the 'div id', as below:
$(document).ready(function(){
$(".box").click(function(e){
var newvar = ("#" + $(this).attr("id") + "Contact");
position();
if(popupStatus==0){
$("#fadedBG").css({
"opacity": "0.5"
});
$("#fadeBG").fadeIn("slow");
$(newvar).fadeIn("slow");
popupStatus = 1;
}});
Now that part of the code is all fine and dandy, however the continued functions, e.g. 'position()', doesn't seem to pick up the newly defined variable.
The rest of the code is outside the brackets of the 'click'-event above, and would look something like:
function position(){
var popH = $(newvar).height();
var popW = $(newvar).width();
...
How come doesn't the continued functions recognize the defined variable 'newvar'? Is it because the code loads as a whole and can not pick up variables later, as when a 'click' event is triggered? Are there ways around this?
