selection

问题 ::selection { background: #000000; color: #ffffff } Is resulting in a dark grey selection color, not full black ( #000000 ). Changing opacity makes no difference. How do I make the selection color appear as #ffffff ? 回答1: This worked for me: ::selection { background: rgba(0, 0, 0, 0.99); color: #FFF; } 回答2: I had the same problem, I had to change the code to background-color instead since the above solution did not work for me. ::selection { background-color: #000000; color: #FFF; } 来源： https

问题 Is there a way to capture an attempt to change currently selected item in the WPF's TreeView and possibly cancel it? Elements in the treeview represent pages with some properties. I would like to ask user if he wants to abandon changes made on the page, save them or stay in the current page. 回答1: Well you're probably not going to like the answer... the WPF TreeView is an unfriendly fellow. Ok, first things first... capturing an attempt to change the selected item : The easiest way to do this

问题 There are tons of questions like this one and every answer I've seen is: use user-select: none . That surprises me, because disabling selection completely is in most cases very bad idea. I want to disable selection in my HTML5 app, because I use plenty <a> elements without hrefs and when user clicks them fast enough, they get highlighted. That's bad. But I still want them to be able to select their text normally, by holding mouse button down and dragging. 回答1: not too sure i understand your

问题 I can already do this for safari and IE like in this fiddle: http://jsfiddle.net/cyk8y/ (The code is a bit complicated or/and messy but it's just so you can see the final result I want). I took the principal code from here: Set a selection range from A to B in absolute position In the comments of the answer, Tim Down gave me these links: How to get a word under cursor using JavaScript and Creating a collapsed range from a pixel position in FF/Webkit to help me making my code working in FF and

问题 I have implemented Roulette wheel selection in GA . TotalFitness=sum(Fitness); ProbSelection=zeros(PopLength,1); CumProb=zeros(PopLength,1); for i=1:PopLength ProbSelection(i)=Fitness(i)/TotalFitness; if i==1 CumProb(i)=ProbSelection(i); else CumProb(i)=CumProb(i-1)+ProbSelection(i); end end SelectInd=rand(PopLength,1); for i=1:PopLength flag=0; for j=1:PopLength if(CumProb(j)<SelectInd(i) && CumProb(j+1)>=SelectInd(i)) SelectedPop(i,1:IndLength)=CurrentPop(j+1,1:IndLength); flag=1; break;

问题 I wrote a code to detect the end of selection using javascript, and to place a marker at the end position. See this jsfiddle: http://jsfiddle.net/vCwwN/ The above code do the following: It handles all LTR scripts (e.g. English) properly (showing marker at the end correctly). For LTR scripts (e.g. English) It handles whether the selection is forward (from left/top to right/bottom) or backward (from right/bottom to left/top) properly showing the marker where the selection stopped (using mouse

问题 This is a follow up to my previous question Delphi TStringGrid multi select, determining selected rows regarding Delphi String Grids. It's a different question. I was looking more closely at the ONSelectCell Event TSelectCellEvent = procedure (Sender: TObject; ACol, ARow: Longint; var CanSelect: Boolean) of object; I noticed that the TStringGrid.Selection.Top,Bottom properties are not necessarily accurate (within the event itself). Basically, if someone goes from selecting multiple rows to
