counter

问题 I have a MATLAB function block in simulink and for each step simlulink does I want to input a counter with increment 1. Ex: 1st Step -> Acc=1 2nd Step -> Acc=2 I tried using a Count up block + Pulse generator but the time step of simulink is not constant. Any ideas? 回答1: A common way to do this is to use a sum and a memory block with an initial condition of 0. It should count steps in both fixed and variable step simulations. In fact I believe this would be build and perform very much like an

问题 Is it possible to have a pure Javascript text remaining counter that outputs the value in a <span> or <p> tag rather than an input field? I can only find Jquery solutions or ones that output in input fields. 回答1: Have seen over the net that a lot of people are wanting a remaining characters counter that is pure Javascript and doesn't preview the number in an input box.

问题 My data are conversation threads from a webforum. I created a function to clean the data of stop words, punctuation, and such.

Here is my code below: def post_to_words(raw_post): HTML_text = BeautifulSoup(raw_post)

问题 How can I implement counter on application icon on the desktop? (like SMS application shows number of unread messages) Should I implement widget for the same? Is there any tutorial? 回答1: You cannot modify an application icon - the path to icon is stored inside AndroidManifest.xml, both files are signed with your certificate, application cannot write to it's own .apk file. You may try a hack - install one "wrapper" app, and let it install/uninstall bunch of other dummy apps, which will have an

问题 There are so many different counter scripts I'm not sure where to start, what's overkill and what's not. I'm looking for a simple counter script that fires when the target element first appears into view onscreen (for example, does not fire until scrolled into view) The idea is that all I have to do to get the element to animate/count when scrolled into view, is give it a class of counter . For example, html will be: <span class="counter">99</span><span class="counter">55</span> First, those
