refresh

问题 I have a web app which pulls in information via ajax after the page loads. When a user leaves the page, then hits the 'back' button in their browser, they see the page as it looked on initial load. What I need to have happen is have all javascript run as if they hit the 'refresh' button. I have tried setting the Cache-Control and Pragma headers, but this didn't help. I know this is possible, as Google does it in many of their applications, such as gmail and google reader. Any ideas? Thanks!

问题 My app uses an API from an external JAR file. This JAR file has been added into my project and added in the build path. My project builds and runs just fine, but now I need to update the JAR file (some code in those classes has changed). I created a new JAR and copied it into my project after removing the old one. Do I need to "re-import" the JAR file or is there some way for Eclipse to refresh/re-examine the JAR file Im removed and re-added ? 回答1: You should try to right click on the package

问题 I'm using a MediaController and MediaPlayer together, to create a simple audio player in Android, taken from an example I found here on this site. However, after much search I could not find the solution to my problem: the progress/seek bar doesn't refresh while the music is playing. It just updates itself when something on the MediaController is pressed (Play/Pause, forward, etc). Any easy fix for this that I'm not getting ? NOTE: My MediaController is declared in XML , and my

问题 I have a JTable inside a JScrollPane. After calling my function which should populate the table I can't see any changes! I'v tried with table.repaint() , model.fireTableDataChanged() and probably some other stuff that I can't remember anymore - nothing worked. What am I doing wrong?? My function: public static void fillVodicTable(JTable table){ DefaultTableModel model=new DefaultTableModel(); //also tried (DefaultTableModel)table.getModel(); table.setModel(model); model.setColumnIdentifiers

问题 I have a listview, all nicely displayed. I add an item to it, using the exact same function I used to put the original items in it with. If I don't refresh the listview, the new item doesn't get enhanced (no surprise there). But when I DO call refresh, the enhancement is incomplete. Here's the item as entered: <li data-role="fieldcontain" id="flip-li-38"> <div class="containing-element"> <label for="flip-38">A B:</label> <select name="flip-38" id="flip-38" data-role="slider" data-mini="true">

问题 I am using Angular 2 and have a grid (ag-grid-angular) with enableServerSideSorting=true and it's working fine only for the first time: the data is loaded and placed in the grid view as expected. When I click on a column to sort that column (which happens automatically) the data is fetched again by calling getRows(params) . The problem is that I have several other input fields: Tabs: to change the type of elements displayed (for example persons or cars). Text field: which is used to enter
