loading

As you know the iphone guidelines discourage loading uiimages that are greater than 1024x1024. The size of the images that i would have to load varies, and i would like to check the size of the image i am about to load; however using the .size property of uiimage requires the image to be laoded... which is exactly what i am trying to avoid. Is there something wrong in my reasoning or is there a solution to that? thank you all Ole Begemann As of iOS 4.0, the iOS SDK includes the CGImageSource... functions (in the ImageIO framework). It's a very flexible API to query metadata without loading the

I know there are thousands of examples on the internet, but I want for the script I already have to display a loading gif image while the data is retrievedd. My java knowledge are poor, therefore I'm asking how to change the following: <script type="text/javascript"> $(document).ready(function(){ function getData(p){ var page=p; $.ajax({ url: "loadData.php?id=<? echo $id; ?>", type: "POST", cache: false, data: "&page="+ page, success : function(html){ $(".content").html(html); } }); } getData(1); $(".page").live("click", function(){ var id = $(this).attr("class"); getData(id.substr(8)); }); })

I'm working on a site which contains a whole bunch of mp3s and images, and I'd like to display a loading gif while all the content loads. I have no idea how to achieve this, but I do have the animated gif I want to use. Any suggestions? mmattax Typically sites that do this by loading content via ajax and listening to the readystatechanged event to update the DOM with a loading GIF or the content. How are you currently loading your content? The code would be similar to this: function load(url) { // display loading image here... document.getElementById('loadingImg').visible = true; // request

Is it possible to start an event when an UIWebView (Iphone) has finished loading the URL. How can I find out, the current URL of the UIWebView? Yes, that's possible. Use the UIWebViewDelegate protocol and implement the following method in your delegate: - (void)webViewDidFinishLoad:(UIWebView *)webView If you want the URL, you can get the last request using the property request : webView.request.URL None of the found solutions worked for me. Then I found this example which at least works much better than any other solution I found on Google/StackOverflow. uiwebview-load-completion-tracker Very

When loading a widget if it cannot find a resource or something it says Problem Loading Widget. That's all! Amazing! This message remains on the home screen and does not even say which widget it had trouble loading. I figured it out by trial and error but I would like to know if there are any places to find the error message when this occurs. Where will Android say what problem it had loading the widget or even which widget it failed to load? As said in comments, check logcat. What you will see is a NullPointerException. I have had this before too. Check elements you used in the view in a

Basically that's the question (parentheses are important) Nick Craver .ajaxStart() and .ajaxStop() are for all requests together , ajaxStart fires when the first simultaneous request starts, ajaxStop fires then the last of that simultaneous batch finishes. So say you're making 3 requests all at once, ajaxStart() fires when the first starts, ajaxStop() fires when the last one (they don't necessarily finish in order) comes back. These events don't get any arguments because they're for a batch of requests: .ajaxStart( handler() ) .ajaxStop( handler() ) .ajaxSend() and .ajaxComplete() fire once
