I'm working on Android right now in Phonegap/Cordova and no matter what I do, I can't get a certain div to resize properly. It gets populated with a bunch of child-nodes in my Javascript and unless I hardcode the div to some ridiculous height, some of those get hidden. The weird thing is, when I set an "alert();" either before or after this...
var newheight=entlist.length*200;
newheight+=200;
document.getElementById('container').style.height=newheight+'px';
...it will show up properly. Also, "entlist" is a list of all the entries that get turned into child-nodes of 'container.' The idea is to make 'container' as tall as it needs to be to fit all those, plus a bit of a buffer, just in case, at least until I get it working and see what it looks like.
The fact that it appears properly with the alert made me think that the div simply needed to be redrawn. As such, I've tried...
var div=document.createElement("div");
document.getElementById('container').appendChild(div);
document.getElementById('container').removeChild(div);
...and this, adding to the height every time a child is added...
var cH = document.getElementById("container").offsetHeight;
document.getElementById("container").style.height = (cH+150)+"px";
...setting 'container's height to "auto", and finally...
document.getElementById('container').innerHTML = '<p>test</p>';
So, I've tried everything I could find on the subject. If someone could help me figure this out, I'd really appreciate it! Thanks.
Found the answer! The div was inside of an iScroll wrapper and I didn't realize that there was even an option to refresh it. I just added one line to make it into...
var newheight=entlist.length*200;
newheight+=200;
document.getElementById('container').style.height=newheight+'px';
myScroll.refresh();
...and it worked like a charm. :)

I have a strange problem in my web-app (php) that I noticed recently.
1 month ago it worked just fine.
When I hover above a certain < TEXTAREA > or over 2 buttons (add, exit),
in a DIV, the DIV gets filled with its background color, making the INPUT, TEXTAREA and 2 buttons invisible.
This DIV is practically a window with 2 inputs and an OK and exit button,
that I hide and show, as a "window" thing would be in Windows.
The moment I hover any other button in the page (so I do a mouseOver), the DIV
shows up again, and it starts working the proper way.
So the problem is when i hover on the TEXTAREA and the 2 buttons, the DIV gets gray.
thanks!
i hope it's not a Chrome bug, in Firefox it seems to work,
but again in Opera it doesn't. So strange.
took at look at your site in Chrome and was able to replicate your problem easily.
by using the "Element Inspector" i removed overflow:hidden from .my_links_header_container and could no longer replicate the problem.
i tested it several times by reloading the page.
on page load, the problem existed, but immediately. after i removed the overflow:hidden, it 100% did not occur again.
on a side note, you have an inline style="display:block" on your .add_link_table, which is not really a table element but a div. that's redundant because a div is a block element by nature -- perhaps it was a table element previously?
i also noticed several elements whose natural display was overridden by your CSS. i think part of this problem is related to flip-flopping your elements and displays.
Seems to be a webkit issue.
This may not be a good solution, but give it a try
I am modifying you addLink method (use plain javascript or jquery selectors as you like, Ive kept the original code as it is)
function addLink()
{
var addLinkTable = $("#add_link_table");
if(document.getElementById('add_link_table').style.display=='block')
{
document.getElementById('add_link_table').style.display = 'none';
}else{
addLinkTable.css("visibility","hidden");
document.getElementById('add_link_table').style.display ='block';
setTimeout(showTable,10);
function showTable(){
addLinkTable.css("visibility","visible");
}
}
document.getElementById('link_name').focus();
}
Try it out with by switching visibility or opacity or height
Well as the title says.
Right now each signature (on a forum) div got:
<div style='height:Xpx;overflow:scroll'> (X = depends on each signature due to the image heights shifting)
And I want to change the height so I don't have to scroll through each signature, but showing all images directly.
Here is the right part of a signature:
http://puu.sh/4xOW7.jpg (couldn't use the website-image-feature due to not having 10 rep)
And I tested around and managed to make it like this:
http://puu.sh/4xPar.jpg (it's much more further down)
and like this..
http://puu.sh/4xPco.jpg (couldn't post more than 2 links -_-)
I also tried to remove the overflow:scroll, change it, and so on. (also tried removing height: etc)
But I just can't get it to simply remove the scrollbar - making all images show normally. I'd really appreciate help! :)
instead of style="height:250px;overflow: auto;"
you need style="display:inline;"
I have a website that I am developing and I have multiple Divs on the main page. I have a div on the right side of the page labeled right_bar2 and I want it to change every 5-10 seconds. The entire div will just be an image that is a link. Basically I assumed the easiest way to do this would be to have a div with a bunch of hidden div's in it and then maybe some javascript that unhides one div at a time and then hides it again and unhides another. However I am unsure the best way to do it. I have looked at a bunch of example and can't get it to work 100% correctly.
Thanks for any advice ;)
JsFiddle examples would be great!
I tried something like this http://jsfiddle.net/VENLh/4/ but in my rails environment/setup, it breaks multiple things, so I'd like something cleaner and easier.
I cleaned it up a bit in this fiddle, but if you said the original breaks multiple things in your original environment, this might not fix them. What specifically did it break?
What I cleaned up was to avoid the need to keep a manual count of the DIVs for the JS or to worry about their IDs. The code is pretty simple:
$(function() {
var $divs = $('div', '#container'),
total = $divs.length,
counter = 0,
showDiv = function() {
$divs.stop().hide();
$($divs[counter]).show('fast');
counter = (conter + 1) % total;
setTimeout(showDiv, 3000);
};
$divs.hide();
showDiv();
});
I didn't perform one optimization that should probably be done. You probably should cache the results of the jQuery selectors on each DIV. It would be easy to do with a jQuery map statement, but I didn't want to muddy the waters here.
The only problem I can see in this case is if you are going to use heavy image, it may take some time to load. As the image will start getting loaded when you show it first time. So for this I would say you should keep the opacity 0 and load the image at the time of pageload.
And also to remove the delay you are having where one div is getting hidden and other is getting visible can be removed by using opacity. reduce opacity of one from 100 to 0% and for other increase from 0 to 100%.
function allowscroll()
{
if (screen.width<1200){document.getElementById('html').style.cssText='overflow-x: scroll !important;';};
}
<body onLoad="allowscroll();">
hi there, the above code works for any element, e.g. subbing "html" for "wrapper", but how is it possible to edit the css applied to html? Basically, because of overflow:hidden not inheriting in ie7 - which causes a big empty righthand margin and horizontal scrollbar (only in ie7, ie 8 compatibilty), ive set the css to
html {overflow-x:hidden;}
this is the only way to fix it without losing necessary functionality, e.g. overflowed graphics visibilty.
and this is all well and good, however, lower screen resolutions need the horizontal scroll just to see all of the page itself, so I'm attempting to restore the horizontal scrollbar for those users - and restore the big right margin for anyone who happens to be, for example ie7 1024 by 768 - I can live with that (unless anyone happens to have a superdupa solution).
document.getElementById('html').style.cssText='overflow-x: scroll !important;';
So the above code works for editing the CSS of any element, but not the CSS of the html.
I've also tried:
function allowscroll()
{
if (screen.width<1200){document.getElementByName('html').style.cssText='overflow-x: scroll !important;';};
}
and
function allowscroll()
{
if (screen.width<1200){window.style.cssText='overflow-x: scroll !important;';};
}
I would really appreciate any help, - if it helps in seeing the solution, the link where this applies is: delight design, basically, its how to take out:
html {overflow-x:hidden;}
from the css when in lower screen resolutions...
many thanks
Will
There are a bunch of different ways to get the html element:
document.documentElement
document.getElementsByTagName('html')[0]
document.body.parentNode
But in all honesty, there must be a better way. I don't have time right now to track down what exactly happened here, but from what I can tell, adding position:relative to whatever needs the overflow might help.
Try document.getElementsByTagName("html")[0]
Note I just edited the answer as getElementsByTagName returns an array. You want the first element in that array.
Just use the documentElement:
document.documentElement
It has full browser suport.
I have a form which is a simple CRUD.
I am trying to display a cool looking success message when user enters or deletes a record. I've seen this a lot around the web.
I am very new to jquery. does anyone know any examples that would show how to do this?
Basically a div that would slowly dim out.
Your question is a little vague as a "cool looking success message" is not much to go with.
If you are interested, however, through answering questions here I have replicated the functionality of two of Stackoverflow's "notification" features that people seem to enjoy: the banner at the top of the page that comes up when you get a new badge, etc. and the red boxes around the site whenever something goes wrong with an action. I've used techniques similar to these to show success messages in my applications and my clients have loved them.
To show the top banners - demo
To show the red boxes - demo
The examples are very simple, as all it is doing is showing a DIV somewhere in the document and fading it in and out depending on the situation. That's all you really need to get started.
In addition to this, if you are a Mac fan (and even if you're not) there is the jQuery Growl plugin which is based on the OS X notification system. I am also a big fan of using the BeautyTips plugin to show messages near an element, as the bubbles are very nice and easy to style.
I really like jGrowl. It's very unobtrusive as the messages appear in the left corner and the user can continue to do whatever he's doing, but he does get feedback from the system. And it also looks very fancy :).
Just throw in a new absolutely positioned div and use the fadeOut-function to animate it's opacity with a slow animation.
Something like this:
var newDiv = $('div').css({position: 'absolute', left: '100px', top: '100px'}).text('SUCCESS!!!').appendTo($('body'));
newDiv.fadeOut(5000);
This should work:
function showSnazzySuccessMessage(text)
{
if($("#successMessage").length < 1)
{
//If the message div doesn't exist, create it
$("body").append("<div id='successMessage' style='text-align:center;vertical-align:middle;width:400px;position:absolute;top:200px;left:300px;border:2px solid black;background:green;margin:20px;display:none'>" + text + "</div>");
}
else
{
//Else, update the text
$("#successMessage").html(text);
}
//Fade message in
$("#successMessage").show('slow');
//Fade message out in 5 seconds
setTimeout('$("#successMessage").hide("slow")',5000);
}
You'll have to play with the style to get it to look the way you want, but you get the idea.
Perhaps you're looking for something like this or a straight fade like this. There are a few effects to choose from.
