refresh

问题 I have a problem. I use extjs grid . This grid will be refreshed every seconds . I refresh with this function: ND.refresh = function() { ND.commList.load(); } var refreshSeconds = refreshRate * 1000; var t = setInterval('ND.refresh()', refreshSeconds); But when someone selected a row to highlight it it reset this selection. How can I remember the selected row and highlight it again after refresh? This is my grid: var grid = Ext.create('Ext.grid.Panel', { autoscroll: true, region: 'center',

问题 So I'm trying to return items from an array that's made out of user inputted info from cookies, and it works fine, except when you first visit the page from the previous page, nothing shows up, and you have to refresh it to actually see the array. I have no idea why it wouldn't show up the first time around? (There are some JavaScript alerts in there that work fine. It's only the array that I'm having trouble with.) Here's my code, any advice would be great, thanks: $usergatsby = $_COOKIE[

问题 I'm New to QT. I understand that you can force a display refresh, but I've pulled all my hair out trying to figure out how. Here is what I'm specifically trying to do. I press a button (onClick signal event), which runs code that changes an image (QLabel) on the display, waits for input, and then proceeds by changing a new image (different QLabel). I've tried everything and the display doesn't refresh until the onclick signal event code is complete. Right now, I'm not waiting for user input,

问题 Is there a Page.Refresh type of command to refresh a page? I don't want to redirect to the page or refresh in JavaScript. 回答1: I think this should do the trick (untested): Page.Response.Redirect(Page.Request.Url.ToString(), true); 回答2: Careful with rewriting URLs, though. I'm using this, so it keeps URLs rewritten. Response.Redirect(Request.RawUrl); 回答3: Response.Redirect(Request.Url.ToString()); 回答4: You can just do a regular postback to refresh the page if you don't want to redirect.
