loading

问题 This is a Q&A post. To inform the many other users I saw who struggled with this issue as I browsed through StackOverflow's database. None of these users ever got a solid answer (and most of them were posing the question years ago so I wasn't going to bump the post). The issue many struggled with is as follows: When you try to load a page in a UIWebView and the page then loads another page maybe via an iFrame or it loads an advertisement through javascript you end up getting the page loading

问题 I have a loading animation which I initially hide in my application.js file: $('#loading_field').hide(); I have an autocomplete field, and I want the animation to appear when the user starts typing, and for it to disappear when the autocomplete suggestion results appear. Below is my jquery code for the jquery ui autocomplete plugin: $(".showable_field").autocomplete({ minLength: 1, source: '/followers.json', focus: function(event, ui) { $('.showable_field').val(ui.item.user.name); return

问题 I'm looking for a way to conditionally load and keep the execution order of some javascript files (external and internal) without any library dependency. Basically, what I want to do is load them up only if the browser supports localStorage. Here's basically my shell: if (window.localStorage) { //load up JS only if it's needed var body = document.getElementsByTagName('body')[0], js1 = document.createElement('script'), js2 = document.createElement('script'), js3 = document.createElement(

问题 I have a website that loses layout scheme while the page isn't loaded. What I'd like to do is to have an animation linked to the loading progress, like a progress bar but without the bar. For example, a simple animation that would link the progress to the opacity of the logo. So, when the page was 50% loaded, the logo was at 50% opacity; when the logo was 100% the page was loaded and the loading progress would .fadeOut() . I understand I can use $(window).load() to hide the animation <div> .

问题 Since MPI doesn't offer binary compatibility, only source compatibility, we're forced to ship our solver source code to customers for them to use our solver with their preferred version of MPI. Well, we reached the point where we cannot offer source code anymore. As a result, I'm looking into ways to create a wrapper around MPI calls. The idea is for us to provide a header of stub functions, and the user would write the implementation, create a dynamic library out of it, and then our solver

问题 I have a JTable that loads data from a database. Because sometimes there's too much data, I would like to add a loading circle inside the Jtable to notify the user that the data is being loaded. Here is an image of how I would like it to be: Is this possible? How can it be done in Swing? PS: I don't want to use the progress bar, I just want the circle inside the table. UPDATE: The table is part of the GUI and I only want to disable or show the loading inside the JTable and leave the other

问题 I have a simple jquery code to send a content in a jQuery modal window with ajax! everything is working without any problem. in normal, after clicking on the send button, after 1-2 seconds this code showing the result, function AddFastqpro(action) { var b = {}; b[dle_p_send] = function () { var response = $('#dle-poke').val() $.post(dle_root + 'engine/ajax/fast.php', { text: response, action: action }, function (data) { if (data == 'ok') { DLEalert(dle_p_send_ok, dle_info); } else { DLEalert

问题 example: Go to your Facebook wall, scroll the end of the page, Facebook will load more wall posts asynchronously . Or just click on an images in your wall post. The image dialog (with comments and larger image) is loading asynchronously as well. (You can see the GET requests with firebug). But by looking and the firefox tab, you see the loading indicator, just like when a postback occurs. I know this can be achieved by using an IFrame and changing its src. Just like what iGoogle does. But I'm

问题 I'm building a plugin that will allow a developer to add various features to a class with a simple declaration in the class definition (following the normal acts_as pattern). For example, code consuming the plugin might look like class YourClass consumes_my_plugin option1: :value1, specific_method_to_use: :your_method end My question arises because I want to error check that the value provided for the :specific_method_to_use parameter exists as a method, but the way code is typically
