问题 I have to read a text file which can begin with optional comments. In practice I have to skip any line at the beginning of the file that doesn't begin with '@' or '>'. In my test case the file looks like: # Sun Jul 12 22:04:52 2009 /share/apps/corona/bin/filter_fasta.pl --output=/data/results/solid0065/primary.20090712170542775 # Cwd: /state/partition1/home/pipeline # Title: solid0065_20090629_FC1_Tomate_Heinz_4_5_Kb_Tomate_Heinz_4_5_Kb_01 >125_963_316_F3 T1230330231223011323010013 So I have

问题 How can I clear the back stack in windows apps (not windows phone)? I am using MvvmCross v3. Where is the most correct place to put it?

PHP: Browser go back a page

由 我的未来我决定 提交于 2019-12-13 17:43:15
问题 I want for something like this: <?php if($something) header('Location:javascript:history.go(-2)'); ?> but header('Location:javascript:history.go(-2)'); doesn't work. Any alternatives? I don't know the page the user was just on, so I can't hardcode the url. 回答1: From your point of view, i think you might be looking for something like this: <html><head></head><body> <?php if($something){ ?> <script type="text/javascript"> window.history.go(-2); </script> <?php } ?> </body></html> 回答2: As long

Internet Explorer 10 back button caching

由 淺唱寂寞╮ 提交于 2019-12-13 14:28:24
问题 In Internet Explorer 10, if you press the back button it would try to fetch the previous page from the browser cache. This behavior differs from virtually every other browser including IE9 in which pressing the back button would do a full reload of the previous page instead of reusing the cache. How do I communicate with IE10 from the website, possibly using javascript/headers etc to not do this cache utilization for the site globally? (Note: I'm not looking for an IE10 setting to disable

When the client gets to a page by hitting the back button, how to make it load a fresh copy instead of cached one?

由 血红的双手。 提交于 2019-12-13 13:30:22
问题 I'm trying to get a page to load a fresh copy from server when the client arrives at it by hitting the back button. By default it loads the old cached copy from browser memory. Is there a way to do that? (in node.js) Adding an empty function to window.unload as mentioned here doesn't work for me. 回答1: Tried all the Meta tags, they have no effect. But the question referred to by @BenJ mentions "when you don't have access to the web server's headers".. I actually do have access to and can set

问题 I have changed the back button in my navigation bar in one of my view controllers to a custom button and gave that button an action to do when pressed by: self.navigationItem.hidesBackButton = true let backButton = UIBarButtonItem(image: UIImage(named: "backArrow"), style: .plain, target: self, action: #selector(self.back)) self.navigationItem.leftBarButtonItem = backButton This worked perfectly and I was able to keep the back swipe to pop the view controller by using: self

How can I redirect to home when user click on back button after logout?

由 落爺英雄遲暮 提交于 2019-12-13 05:41:56
问题 I was wondering how can I redirect users to my hompage after they logged out when they hit the back button, kind of like facebook does. I was playing around with some javascript but nothing seemed to work. PS: This will be for a Wordpress theme. 回答1: Hi there check the wp_logout_url($redirect_url). 回答2: If you use sessions, you can check if the user is logged in when viewing an authenticated page, and if not, send the headers to your homepage. 回答3: Javascript seems like the way to do it.

Missing Back Button from UIViewController in a Navigation Controller

由 一个人想着一个人 提交于 2019-12-13 04:04:18
问题 I have a tabbed table view controller and in one of the tabs, I'm clicking on a cell which takes me to a View Controller instead of another Table view. It's all embedded in a UINavigationController but when I push, I do not get the back button with the name of the previous view controller on it. In the other tabs, I click on a cell and push to another table view and that works fine, but it does not in this case. I've been reading up on this and have certainly set the title of my new view

Browser Back Button Handling in Ajax Based Application

由 佐手、 提交于 2019-12-13 01:40:23
问题 Similar questions have been asked on SO, but I am still looking for a solution and not a workaround. I am working on an Ajax based application and when the user clicks on the Browser Back Button it takes the user to the login page(every page after the login page is ajax loaded). Apparently, this is not what the user expected. We recommended using Bread Crumbs to the client *Page One >> Page Two >> Page Three* but the client insists that they prefer to use the Browser Back Button. Is there a
