I have multiple divs on a page and in a certain div there are more child divs that get floated to go across the page. I want to be able to use javascript to see the width of the window and then divide my set width of the divs to work out how many to display.
I have found the 2 pieces of code. One that measures window width and the other to slice the divs and hide the rest.
$('div').slice(4).hide();
var width = $(window).width();
$(window).resize(function(){
if($(this).width() != width){
width = $(this).width();
console.log(width);
alert(width);
}
});
My Problem is how to select only the divs within my speciedfied div. I have tried this but it hasn't worked. Don't even know if i'm goin in the right direction
$("#mainContent2").append(('div').slice(4).hide());
Is javascrpt the right way to go about this or would css be able to do what I'm after?
Many Thanks
EDIT: HTML
<div id='mainContent>
<p></p>
<div>
<div id='mainContent2'>
<div><img></img><p></p></div>
<div><img></img><p></p></div>
<div><img></img><p></p></div>
<div><img></img><p></p></div>
<div><img></img><p></p></div>
</div>
If you have got the number of div to show in particular div then you can use this code.
$(#mainconetent2 > div).slice(4).hide());
I'm not sure whether I correctly understood your problem, but JQuery offers the child-selector for selecting children of a specific element. Then you have access to its parameters and can set whatever you want.

I'm displaying a list of results on my results page that require me to scroll, which is fine, but the whole page( nav bar, maps next to results, etc) all scroll down as well. I'm trying to figure out how to get JUST the list if results to be scrollable. I've tried to put
overflow-y: scroll
on a number of of the div's surrounding the list and
overflow-y:hidden
on the body to prevent the whole from scrolling down
but nothing seems to work. All I can achieve is a bunch of y - scroll bars that are all unusable,
where the outer most scroll is hidden (disabled) and I can't scroll any of the inner most scroll's, even though there is result content below the screen.
Can anyone suggest another way to create a scrollable div list on one side of the page while the other side remains unscrollable. Just like Airbnb.com's result page. Or please point me to some examples or Fiddle examples.
Try to give your div a fixed size.
The <div> needs to have a set height but you need this to be responsive. The best way to do this to support older browsers is using JavaScript. This <div> will resize to the current window height upon resize, the width is up to you, if you want it like Airbnb's then you'll need to set the width to 50%.
HTML:
<body onresize="setDiv();" style="overflow-y:hidden;">
<div id="listResults" style="border: 1px solid black;overflow-y:scroll;">some list results here</div>
</body>
JS:
function setDiv() {
var x = window.innerHeight;
document.getElementById("listResults").textContent = "height: " + x;
document.getElementById("listResults").style.height = x + 'px';
}
P.S. I only put the border there so you could see that the div was actually resizing.
I have two divs that contain two other divs each. One containing DIV's display is set to none. I have a button that toggles the containing DIVs so I can alternately hide/show the containing div and thus the two divs inside. The inside DIVs are set the 49% width, floated left/right. Problem I have is the fist time the visible DIV is hidden and the hidden one displayed the inside two divs are way too wide. If I resize the width of the browser just a tiny bit with my mouse they are the desired size and any time I toggle the visibility from here on out all is fine. If I reload the page it is wrong on the first toggle. Works the same in IE 10 and Chrome so don't think a browser issue.
The inner two divs both contain high charts that are generated and rendered to the inner divs I want them to be side by side and almost (99%) the width of my page.
Here is snipped of my DIVs to be hidden and shown that contain the inner DIVs with highcharts
<div id="highChartsNG" style="width:99%;display:none;">
<div id="FillRateHigh" style="border:2px solid black;width:49%;float:left;"></div>
<div id="WaitTimeHigh"style="border:2px solid black;width:49%;float:right;"></div>
</div>
<div id="LowChartsPEAK" style="width:99%">
<div id="FillRateLow" style="border:2px solid black;width:49%;float:left;"></div>
<div id="WaitTimeLow"style="border:2px solid black;width:49%;float:right;" ></div>
</div>
This is a snippet of the javascript function I call on a button click to toggle on/off on the display of two containing DIVs
document.getElementById("highChartsNG").style.display = "none";
document.getElementById("LowChartsPEAK").style.display = "block";
Fiddle showing problem, see comment of mine below on how to reproduce http://jsfiddle.net/rplace/UTTz4/1/
Okay, after hours of searching I finally found the problem (I think). I was determined to find the solution =).
The problem is multiple-fold.
The first problem was the display:none; property on the second chartcontainer. For some reason the widths calculated for the charts and their containers were incorrect for the hidden div. So I removed the property from the HTML, and instead hid it dynamically with document.getElementById("LowChartsPEAK").style.display = "none"; in the JS right after the chart rendering functions. If you do this, your SVG's will fit your containers already, although the last one has a slight shift.
Apparently HighChart doesn't like percentage-based parent containers. When you go to your updated fiddle , run the fiddle with both:
<div id="wrapper" style="width: 800px;">
<div id="wrapper" style="width: 100%;">
Open the console and check the results (container name - SVG width - container width). When the wrapper is given a pixel width, all container widths are equal (as it should be). Now check the wrapper with percentage width: your last SVG will be about 6 to 20 pixels smaller. The only solution I have found for eliminating that small shift in the last container, is that somewhere a top container must have a pixel-width.
EDIT: pt's and em's also work. It's only % that causes problems
If you are hiding DIV, you should be aware that browser won't calculate %-based widths with display:none. Then if browser won;t calculate DIV, then also Highcharts are not able to do it ;)
Check this FAQ - when showing chart update his size or call reflow().
I was looking into ebay.com and the way that items are displayed (scroll down on the page and see div content the items boxes have different height)
<div id="content" class="content">
I am thinking of doing something similar but the problem that I am having is that somehow I need to cater for the spaces between each item because the divs will be generated automatically.
Can I do this with css (maybe grouping some items together and keep a margin / distance from each other automatically)?
Example fiddle here:
You can do it with CSS up to a certain level of quality, by floating elements;
after that, you must use JavaScript.
But you should really check out Masonry, because I guess it's exactly what you need.
You can use :first-child (or :last-child) to change the margin on the first or last element so you get neat spacing.
I am trying to write a zoom in/out feature on a web app I am making using the jqueryUI slider.
I am having difficulty handling when my parent div shrinks too much, and cramps its child containers.
<div class="puck originator inline-block" style="width: 310.5px; left: 0px;">
<div class="conflicted inline-block originator">
<div class="right-number">I should stay</div>
<div class="left-number">I should stay</div>
<div class="middle-number">I Should disapper</div>
</div>
</div>
Here is the relevant section of code I have
http://jsfiddle.net/aQKwE/
Basically I have the parent div (class 'puck') that is being shrunk using a jquery slider. For this code I just used a text box, but same idea.
When I shrink that div, the containing divs stick around and are very garbled.
I want to be able to remove the middle child div when it becomes to cramped, leaving the left and right child divs to occupy all the space
Furthermore, if it becomes to cramped yet after that, I want to remove the right div, leaving only the left.
Finally I want to be able to remove all contents so that nothing more than the background of the parent shows.
Is there a way to do this easily, preferably through CSS? I don't want to write more javascript code to set 'display:none' on each child div, since it seems like some CSS rules should handle this.
Any ideas?
There's not really any logic built into CSS to handle something like this. You can set rules based on viewport size, but that won't help in this case.
I updated your jsfiddle with this code so you can test it and see what you think, but essentially I just added some checks in your javascript function to hide based on the width submitted.
var newwidth = $('#text').val();
$(".middle-number").show();
$(".right-number").show();
if (newwidth < 280) {
$(".middle-number").hide();
}
if (newwidth < 180) {
$(".right-number").hide();
}
$('.puck').css('width',newwidth);
I have a page with many divs and style, with my div buried somewhere inside.
I am trying to have a button that automatically makes my div, that includes a video player, resize and capture the whole browser.
In order to do that I am trying to get the current position of the div and then position it relatively so that it'll get to the top-left corner so I could then use document.body.clientHeight/clientWidth.
Can't get this to work.
I tried the approach of moving my div to the first div and then resizing however this messes up the flash player.
Any ideas? any different approaches?
Thanks,
Guy
Use one of the lightbox clones that can handle DIVs. They usually copy the DIV in question into their own view DIV, which helps with positioning issues and you don't have to do anything to the buried div.
I find Multi-Faceted lightbox to be very easy for customizations:

but there are lots of others around as well.
Why relative?
You should rather use fixed instead of relative. Then set positon to 0,0 and width and height to 100%.
Simple js can do this.
On click, just set the div's style to 'fixed', and position 0,0. Like:
var theDiv = document.getElementById('yourDivsId');
theDiv.style.position = 'fixed';
theDiv.style.top = 0;
theDiv.style.left = 0;
This should do the trick:
<div style="position:absolute;top:0;left:0;width:100%;height:100%">
