progress

Similar to: Jquery slider with progress bar I have this slider and progress bar, but I want the progress bar synced with with the "previous" and "next" buttons as well. So when you click "next" the progress bar starts from beginning. http://jsfiddle.net/aidenguinnip/8rJws/ $(window).load(function(){ var currentIndex = 0;// store current pane index displayed var ePanes = $('#slider .panel'), // store panes collection time = 3000, bar = $('.progress_bar'); function showPane(index){// generic showPane // hide current pane ePanes.eq(currentIndex).stop(true, true).fadeOut(); // set current index :

drawRect调用场景 视图第一次显示的时候会调用。这个是由系统自动调用的，主要是在 UIViewController 中 loadView 和 viewDidLoad 方法调用之后； 如果在 UIView 初始化时没有设置 rect 大小，将直接导致 drawRect 不被自动调用 该方法在调用 sizeThatFits 后被调用,所以可以先调用 sizeToFit 计算出 size ,然后系统自动调用 drawRect: 方法； 通过设置 contentMode 属性值为 UIViewContentModeRedraw ,那么将在每次设置或更改 frame 的时候自动调用 drawRect: ; 直接调用 setNeedsDisplay ，或者 setNeedsDisplayInRect: 触发 drawRect: ，但是有个前提条件是rect不能为0; drawRect使用注意事项 如果子类直接继承自UIView,则在drawRect 方法中不需要调用super方法。若子类继承自其他View类则需要调用super方法以实现重绘 若使用UIView绘图，只能在 drawRect: 方法中获取绘制视图的 contextRef 。在其他方法中获取的 contextRef 都是不生效的； drawRect: 方法不能手动调用，需要调用实例方法 setNeedsDisplay 或者

I see a lot of example progress bars that show the progression bar being filled up. However, I would just like to know how I could make a progress reflect step by step form progress. A good example of what I would want can be seen Here . Any helpful code or examples/demos from other pages would be good to have. Thanks! If you like the Buffalo one, just have a look at how they do it. First they define a div like this: <div id="progress"> <div id="complete" class="s1"> <div id="marker"></div> </div> </div> Then they use CSS to render the div based on the progress (which is controlled with class=

I've been using Progress<T> and wondered if it can be replaced by Action<T> . In the code below, using each of them for reporting progress, i.e. ReportWithProgress() or ReportWithAction() , didn't make any noticeable difference to me. How progressBar1 increased, how the strings were written on the output window, they seemed the same. // WinForm application with progressBar1 private void HeavyIO() { Thread.Sleep(20); // assume heavy IO } private async Task ReportWithProgress() { IProgress<int> p = new Progress<int>(i => progressBar1.Value = i); for (int i = 0; i <= 100; i++) { await Task.Run(()

Is it possible to get the upload-progress for a form with very large textfields using jQuery ajax? I think the client knows how much bytes have been sent, but when I Google I only find solutions for file-uploads using server-site code. This is my ajax-request: $.ajax({ type: "POST", url: "index.php?action=saveNewPost", data: {textbox1: textbox1,textbox2: textbox2}, contentType: "application/x-www-form-urlencoded;charset=UTF-8", success: function(){ // } }); I was hoping there would be something like "onProgress" with a parameter containing the amount of bytes already sent... Found a solution $

AsyncTask和Handler对比 1 ） AsyncTask实现的原理,和适用的优缺点 AsyncTask,是android提供的轻量级的异步类,可以直接继承AsyncTask,在类中实现异步操作, 并 提供接口反馈当前 异步执行的程度 (可以通过接口实现UI进度更新),最后反馈执行的结果给UI主线程. 使用的优点: l 简单,快捷 l 过程可控 使用的缺点 : l 在使用多个异步操作和并需要进行Ui变更时,就变得复杂起来. 2 ）Handler异步实现的原理和适用的优缺点 在Handler 异步实现时,涉及到 Handler, Looper, Message,Thread四个对象，实现异步的流程是主线程启动Thread（子线程）àthread(子线程)运行并生成Message-àLooper获取Message并传递给HandleràHandler逐个获取Looper中的Message，并进行UI变更。 使用的优点： l 结构清晰，功能定义明确 l 对于多个后台任务时，简单，清晰 使用的缺点： l 在单个后台异步处理时，显得代码过多，结构过于复杂（相对性） AsyncTask介绍 Android的AsyncTask比Handler更轻量级一些，适用于简单的异步处理。 首先明确Android之所以有Handler和AsyncTask，都是为了不阻塞主线程（UI线程）

I am having some problems getting my upload progress bar to work properly. According to the XMLHttpRequest Level 2 specs, I attached event listeners for loadstart and progress like this: var xhr = $.ajaxSettings.xhr(); xhr.upload.addEventListener('loadstart', function(e) {progressCallback(0);}); xhr.upload.addEventListener('progress', function (e) { progressCallback(e.loaded / e.total); }); $.ajax({ url: url, type: 'POST', processData: false, contentType: false, data: formData, xhr: function () { return xhr; } }).done(function (data) { // Finish stuff }) The file is correctly uploaded but the
