I have a div that is absolutely positioned and stretch on all sides using top:
10px; left: 10px; bottom: 10px; right: 10px;
When I try to get the height of the div, using $('#id').height(); I get 0 (zero). Is there a problem calculating the height of elements like this one, or am I missing something?
I'm working on a script to pass the content height to some other element. The whole script is within the document ready function, but somehow Google Chrome thinks the content height is 0 (zero), because it's so fast. When I set a timeout it works correctly, but I don't really like this solution because of the delay.
var contentHeight = ($('body').height();
setTimeout(function() {
var contentHeight = ($('body').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 found this useful script for setting equal column height for divs. But is doesn't account for the padding inside the divs. How to make it calculate the total height including the padding from the heighest column?
Code:
$('#leftcolumn, #content').equalizeHeights();
(function($){
$.fn.equalizeHeights = function(){
return this.height(
Math.max.apply(this,
$(this).map(function(i,e){
return $(e).height()
}).get()
))}
})(jQuery);
They are not very expert in javascript. I created a script that needs to calculate the sum of text fields. My function is limited to 5 elements, you can simplify and make it work for n elements.
PHP Code:
<script>
function somma() {
var a=eval(document.getElementById("primo").value);
var b=eval(document.getElementById("secondo0").value);
var somma0=(a) - ((a) * (b)) / 100;
var somma0=Math.round(somma0 * 100) / 100;
document.getElementById("somma0").value=somma0;
var b1=eval(document.getElementById("secondo1").value);
var somma1=(a) - ((a) * (b1)) / 100;
var somma1=Math.round(somma1 * 100) / 100;
document.getElementById("somma1").value=somma1;
var b2=eval(document.getElementById("secondo2").value);
var somma2=(a) - ((a) * (b2)) / 100;
var somma2=Math.round(somma2 * 100) / 100;
document.getElementById("somma2").value=somma2;
var b3=eval(document.getElementById("secondo3").value);
var somma3=(a) - ((a) * (b3)) / 100;
var somma3=Math.round(somma3 * 100) / 100;
document.getElementById("somma3").value=somma3;
var b4=eval(document.getElementById("secondo4").value);
var somma4=(a) - ((a) * (b4)) / 100;
var somma4=Math.round(somma4 * 100) / 100;
document.getElementById("somma4").value=somma4;
}
</script>
<input type="text" id="primo" onKeyUp="somma()" /><br /><br />
<?php for($i=0;$i<=4;$i++) { ?>
<input type="text" id="secondo<?php echo $i; ?>" name="secondo" onKeyUp="somma()" value="6" />
<input type="text" id="somma<?php echo $i; ?>" /><br />
<?php } ?>
I'm using JQuery to write content into an otherwise empty iframe like so:
Code:
$('#ifrmID').contents.find('html').html(htmlContent);
The content is coming from an Ajax request. The content gets used more than once on the page for other purposes which is why I don't simply change the iframe src--I have to do an ajax request regardless so I'm trying to avoid multiple calls.
After I load the content, I need modify the height of the iframe so it fits snuggly around the content.
Calculating the height isn't a problem with the exception that it's not always correct and I think it's because the calculation is happening before images have downloaded.
I don't seem to be able to rely on a `load` or `ready` event to delay the calculation. The load event is the only one that tiggers on a change of iframe content, but it doesn't see the new content.
Code:
$('iframe').each(function () {
$(this).load(function () {
alert($(this).contents().find('html').html());
});
});
This will output '<html><body></body></html>' even though I have successfully inserted different content.
Any suggestions on what I'm doing wrong, or if it's possible to do what I want reliably?
Note that a general JS solution will be appreciated as much as a JQuery one.
I just started using jquery a few days ago and am already addicted.Now I am trying to figure out one thing which I can't seem to get answered by Google:I am building a dynamic website where at one place there will be an unclear number of div-elements. So there can be none, just one or several.The plan is to show them by a click on a button via slideDown(). So I wrapped them with another div.wrapper via wrapAll(). This works nicely for any number.Now the thing is: if my .wrapper has no specified height, the slideDown jumps - which doesn't look very nice.So I gave it a height:$('.wrapper').css({'height': $('div').outerHeight()});Presto, the animation works smoothly. But this works only if there's just one div.

I have 6 divs this involves..
<subbody>
<covergroup>
<coverleft />
<coverright />
[Code]....
The cover group contains left & right bar images that repeat vertically as the page expands. The top is just a simple blue background (also content bg color)
Obviously content is the content of the page and both covergroup and content are within the subbody.
Is for the <subbody> tag to be the size of <content> + 5px on top (size of the <covertop>), and the left and right cover divs to expand to the size of subbody.
I guess since I'm using a footer (with image and text) letting the page expand as it wants is out, and I need javascript to make it work.
I'm working on my personal website [URL] and I'm trying to use Javascript to edit some of the height and size attributes of elements on the page, based on the user's window size. I've got the code that gets the window size working, and calculates what I want to set as the "boxSize" but the part that goes into the external CSS to change the values is not working. "boxSize" is a variable that holds just a number. I'm not sure if it's really stored as a number or a string, but I don't think that's supposed to affect anything.
I'm just putting in the relevant part of the code right where it's failing. I figured out (using alert() statements) that the script is definitely working right up until before the two lines given, and failing to get through them.

I am working on a UI that, when you click on a menu option, a div opens and show three divs inside. These divs all have different
heights. The heights are based on the divs content.The problem I'm having is... how do I measure what the divs height should be? IE, how do I grab the height for a div BEFORE it has had any style applied to it.
Trying to get the height of an element whose height is specified in the CSS.

View 3 Replies View RelatedI am in need of a JS script that matches the "li" height with the un-defined height of a absolute positioned block? Sort of like a matching columns script - is this possible? It's for IE6! Oh ya, and it's dynamic un-defined height. I only want it to match the height on hover. Here is a little test page I put together.[code]

I have an html page, with numerous tables in this format:
<table class="tableClass" id="tableID">
<col class="date" />
<col class="reference" />

This (apparently) totals all 'amount' cells in the page, and writes it in *all* the 'total' cells - close, but obviously I'm not correctly specifying that each total should be displayed in its parent.
how to adjust the iframe height by itself if my html height increases. My html code includes a facebook comment at the bottom of my page and the comment will show making it expand the height once users post comments. On the other hand, I'm using a CMS that have its own iframe. I've tried many solutions that can be found on the web but none works. It only can work if I don't put in CMS. Is it possible to adjust the iframe height using CMS or there is no way?
View 7 Replies View RelatedI installed this tool tip plugin
It was super simple to install and customize and I am more than happy with it, except for one little thing.
The position of the tool tip is not calculating properly. I attempted to see if was based on the position element in the CSS of the containing div, but I changed all of them around to see if it would make a difference and it did not fix the problem.
Changing the containing div to position:relative the tool tip actually moves, but it still does not appear in the proper place above the link.
If you go to this example page
the pop up selector is the text under the "Details" table with the darker background. When you click on that text, the tooltip pops up, but about 350pixels away from the text.
How can I use JavaScript to dynamically re-size a DIV on a page so that the div extends vertically to the size of the page or document.
Example: As the page gets longer due to contents, the DIV will also extend to the bottom of the page.
I have been experimenting all evening with different methods, some don't even work.
This is my first time using JQuery, and verrry slowely i'm starting to get the hang of it :)
I've made some slideToggle div's at the right (http://nekodesuka.org/offbeat/), and inside that div there are two divs. One div has an image, the other some text. I want to set the height of the image div according to the height of the div in which the text is... It shouldn't be so much of a problem, but as jquery newbie, i'm wondering how this could be neatly done :)

I am trying to write a script that will take a date of birth and another date and, if the person was over 75 years old on the createdDate, return "true" (otherwise return "false").
Unfortunately my code doesn't seem to return either 'true' or 'false'!
The code is:
var dateofBirth="30/10/1982";
var createdDate="01/12/2010";
var sd = dateofBirth.split('/');
var dob = new Date(sd[2],sd[1],sd[0]);

I want to create a link that a user can click which will create a popup
telling the user their ip address. I have:
var ip = new java.net.InetAddress.getLocalHost().toString();
alert("Your IP address is: " + ip.substring(ip.indexOf("/")+1))
but this does not seem to work. It says the ip is 127.0.0.1. Strangely,
this piece of code used to work but all of a sudden it doesn't for some
unknown reason. Can anyone tell me what's wrong with the above code?
I have two date fields (check in, check out) and "number of days"
field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the
difference in "number of days" field. And if the user will change the
date, the number of days will change automatically.
I am using date of birth field in my application and i m taking date of birth in yyyy-mm-dd format.
I need to calculate age by using this date of birth and should show alert if age is less than 5 years.
I am having difficulty getting the following assignment to run properly:Many companies charge a shipping and handling charge for purchases. Create a Web page that allows a user to enter a purchase price into a text box and includes a JavaScript function that calculates shipping and handling. Add functionality to the script that adds a minimum shipping and handling charge of $1.50 for any purchase that is less than or equal to $25.00.For any orders over $25.00, add 10% to the total purchase price for shipping and handling,but do not include the $1.50 minmum shipping and handling charge. The formula for calculating a percentage is price * percent / 100. For example, the formula for calculating 10% of a $50.00 purchase price is 50 * 10 / 100, which results in a shipping and handling charge of $5.00. After you determine the total cost of the order (purchase plus shipping and handling), display it in an alert dialog box. Save the document as CalcShipping.html.This is what I have after working on it round and round for 4 hours yesterday:
