问题 Is it possible to make sessions per Browser tabs? As example a user opened 2 tabs in his browser: Tab 1 and Tab 2 In Tab 1 he has a session: $_SESSION['xxx'] = 'lorem'; And in Tab 2 the session is: $_SESSION['xxx'] = 'ipsum'; Now on refresh i need to get the current session in the active tab. For example if the user refreshes Tab 2 i need to get the $_SESSION['xxx'] for tab 2 on load which is 'ipsum'. But $_SESSION['xxx'] shouldn't change on Tab 1. Is there any option to save sessions per tab

问题 I know how to put the icon on each tab, that is no problem. I also ran across this : [Stack Overflow thread on pretty much same thing][1] I followed one of the links from that question and found [this][2] Pretty much, it said to use a selector defined in the XML, sure, did that. But there is no id associated w/ it so I am not sure how to get the selector function as a drawable so I can use it as the icon for the tabs. Maybe I am going about this the wrong way. But this is what I have, and

问题 I have just migrated my old ActionBar to new TabLayout ( Support Material Design ). Everything is great but I can't intercept tab selection The method onTabSelected is only called the first time TabLayout is displayed, but when clicking tabs, nothing happens! Any idea what's wrong with this code? tabLayout = (TabLayout) findViewById(R.id.tabs); tabLayout.setTabMode(TabLayout.MODE_SCROLLABLE); mViewPager = (ViewPager) findViewById(R.id.pager); if (mViewPager != null) { setupViewPager(); }

问题 What is the proper way of adding a '+' button tab at the end of all the tab items in the tab strip of a tab control in WPF? It should work correctly with multiple tab header rows. It should be at the end of all tab items Tab cycling should work correctly ( Alt + Tab ), that is, the + tab should be skipped. I shouldn't have to modify the source collection I am binding to. That is, the control should be reusable. The solution should work with MVVM To be more precise, the button should appear

问题 I'm trying to parse a tab-separated file in Python where a number placed k tabs apart from the beginning of a row, should be placed into the k-th array. Is there a built-in function to do this, or a better way, other than reading line by line and do all the obvious processing a naive solution would perform? 回答1: You can use the csv module to parse tab seperated value files easily. import csv with open("tab-separated-values") as tsv: for line in csv.reader(tsv, dialect="excel-tab"): #You can

问题 I'm using session-based cookies with my website. To my complete surprise, I noticed if I set a session cookie (not a persistent cookie), close a tab, and then reconnect to the site, the session cookies are still there. That's not what I would have expected, actually. I would have expected the session cookies to be deleted. If you close the browser, a session cookie is deleted, so why not closing a tab to have the same result? Therefore, I'm using PHP5 and jQuery. Is there anything I can do

问题 I use window.open to populate a new window with varying content. Mostly reports and stored HTML from automated processes. I have noticed some very inconsistent behavior with Chrome with respect to window.open(). Some of my calls will create a new tab (preferred behavior) and some cause popups. var w = window.open('','_new'); w.document.write(page_content); page_content is just regular HTML from AJAX calls. Reports contain some information in the header like title, favicon, and some style
