I would like to know does lazyloading option actually work and how do I verify it. On all my browser, i can see that it actually loads all images at once while the page is loading and not when needed. It does allow me to scroll through even when my images are loading. Each of my images are roughly between 400kb-600kb.
Rgds,

Yes, it does work.
By default, the $LazyLoading option value is 1. That's to say, it will load image for current slide and 1 adjacent slide.
You can manually set $LazyLoading value to 0, in this manner, it will load image for current slide only.
btw, please make sure you replaced src="url' with src2="url" for all images.

When I use Hflex property in a included page in a MVVM approach, it doesn't work.
The problem happens when I include some page inside another, and this page has components whose sizes are controlled by hflex property. I already tried to force the rendering of the components using invalidate on parent window load, or Clients.resize(component) when it is created inside the viewmodel class, but with no success. It just happens in this case: pages included in a MVVM scenario.
Here is a way to see the error: http://zkfiddle.org/sample/3bj6e5j/9-Hflex-not-working-with-include-pages-inside-div#source-1.To see the problem, click in the "Open" label, then a combobox is shown. You can see that the size of the combobox is only updated after resizing the browser window or after clicking in the dropdown button
If I explicitly resize the browser window, then the components are correctly sized.
Could anyone give any idea on how to solve it?
It's actually the javascript who does the fault,
Let me explain more. First you set the src of the include correct.
This is before the javascript is called, and your div don't really have a width at that moment.
So it takes that size, what you see.
Then the javascript is called and and actually he show's the div, but with the rendered with of the include at that moment.
How can you fix it : use zUtl.fireSized.
Here is your working fiddle.
I need to load about 400-500 images to the on single page at a time. Is there a quick way of doing so. I can, in fact, load the images using a for loop but that takes very long?
Many thanks in advance

As IE is very slow in rendering...please do not add all the images at a time...
As you mentioned the size of images in comment user cannot see all the images at a time..so he must scroll down to see remaining images ...so why can't we use scroll event...
At the first shot loop the first set of images (let say 50) ..from then you can use window scroll event ..
On scrolling you can append next set of 50 images...
This will increase the document load time...not only in internet explorer but also in remaining browsers...
I have Struggled with the following issue..
I need an Activity Which have an editbox and a chekbox below it..These are placed at the bottom of the screen...I have a background image for this total screen..I need scrolling of the totalview(background image along with edit and check boxes) while with presence of softkeyboard...
At start It was looks good..But at the time of editing the image is Resize(shrink)/the image is overlapped by the edit & check boxes with adjustResize in manifest option...with adjustPan I could get something of requirement but the check box was still behind the Keyboard...I much tried with Scrollviews and include layout options but couldn't get the required....
Could anyone Suggest me anything regarding this..
At last I found some trick to get out of this....what I did was instead of using scrollviews...etc...just I scroll the Parent layout (ScrollTo(x,y)) to some extent upwards...Which works fine with me...
I've done the prerequisite searching of stackoverflow and looking on the internet. I suspect that the answer is ' This can't be done. ' but I'm hoping someone here might have a solution.
My page loads fine, but many of my YUI components don't fully load before being displayed. For example, my DataTable will resize itself when displaying or my buttons will appear in their native form and then get YUI-fied.
Is there a way to delay the displaying of the page until all the Javascript is finished (i.e. all my YUI components are finished rendering)? I don't know how this would happen, as a lot of the JS depends on the DOM being present to manipulate it.
Is there a way to delay the displaying
of the page
If I understand correctly you would like to hide it until it's done?
If that's the case I have an idea:
add a wrapper around the element you
want to hide (or use
position:absolute to cover it)
give that div a background which use
the color of the surrounding with a
positive z-index
when all your javascript has loaded remove the
z-index or change the color of the background to transparent
Your javascript code would look like this:
do 1. and 2.
load your js
do 3.
Of course it needs to be synchrone.
As an alternative you could use visibility:hidden / visible on the element itself but I dunno for sure if it's well supported.
Try putting your Javascript in the head section of the page, as if it's near the end of the page, it'll load later (making the first elements load faster). OR, better yet, serve up your Javascript compressed and via a CDN, such as Amazon CloudFront so that it loads quickly.
I want to have a static footer image with 5 buttons for navigation in my mobile phone website. The image is here http://www.pintum.com.au/jm/footer3a.jpg. The blue icons should be the default, the yellow icon should only be visible for the hover or active state.
I want to know how can I make this image scale to the correct width on all mobile devices (landscape and portrait) and have links to other pages and make the current/active pages icon the yellow color?
What I have tried so far
I first tried to make a CSS Sprite but that go ugly (complex) quickly. Painful working with widths everywhere so the image scales correctly as I had no way of knowing the height in pixels since the width is dynamic. I could use JS to find the width and calculate height on the fly. But this sounds like overkill.
Next I tried to have a single image with a width of 100% then place div overlays on top of the image. But with this solution I could not figure out how to navigate pages using JavaScript click event, or figure out how I would be able to change the image icon on the selected page http://jsbin.com/uraya5/3/ . And detrmining the correct height for the div
Last I tried to make each button a seperate image. These seems like the easist soultion. But jQuery Mobile adds a bunch of extra styles to the button I do not know how to remove. See http://jsbin.com/uraya5/4
So whats the best/easiest way to do this?
How can I remove the style around
links?
Or can I use a single image CSS sliding door method? To reduce HTTP request.
Ok I figured it out
See soultion here http://jsbin.com/uraya5/10/
I had to:
Set width to 19% of each button for
some reason there is spacing between
each button so 20% does not work.
Set ui-bar-a background to black so
it hides the spaces between my
images
Use this JS code to navigate pages $.mobile.changePage($("#about"),
"flip", true, true);
I would still like to use a single image instead of having 5 different images to reduce http calls. So if anyone finds a eligant soultion for this please let me know.
