问题 It looks like selected some text, but the background color will not disappear when you click it or move cursor. 回答1: You can't use textarea element for this. Just make a contentEditable contentEditable div and use javascript to style it. 回答2: It may be a div with contentEditable set to true 回答3: That could be a div the styled during events and as other suggested make it contentEditable. With regards to textarea I have read similar question here. Check it if it's what your looking for. 来源：

问题 Given x = [5, 30, 58, 72] y = [8, 35, 53, 60, 66, 67, 68, 73] The goal is to iterate through x_i and find the value for y that's larger than x_i but not larger than x_i+1 Assume that both list are sorted and all items are unique, the desired output given the x and y is: [(5, 8), (30, 35), (58, 60), (72, 73)] I've tried: def per_window(sequence, n=1): """ From http://stackoverflow.com/q/42220614/610569 >>> list(per_window([1,2,3,4], n=2)) [(1, 2), (2, 3), (3, 4)] >>> list(per_window([1,2,3,4],

问题 I have been unable to figure out how to paste a range (specifically one row) into a data table using VBA. Right now there is a range of data in a worksheet named "RawData". On another sheet there is a graph that starts at (1, 1) and goes to (100, 33). The variable ThisValue contains the name of the sheet containing the table. The variable x contains the row number of the range I am attempting to transfer. I am currently using this code: Sheets("RawData").Select Cells(x, 1).Resize(1, 33).Copy

问题 I have a calendar table that looks like this: date | qty ------------------- 1998-11-18 | 2 1998-11-19 | 0 1998-11-20 | 0 1998-11-21 | 0 1998-11-22 | 3 1998-11-23 | 0 1998-11-24 | 0 1998-11-25 | 3 I am trying to generate a report which would give the ranges of the entries with the 0 values for quantity ( qty ). I can't hard code the dates, they need to be determined by the value of the second column. From the above, the report should look like this: 1998-11-19 - 1998-11-21 1998-11-23 - 1998

问题 I have a range of cells in VBA that changes each time the code is run. I am trying to write code so that this range is sorted by column F. The problem I am having is that it can only be this specific range of cells. There are other cells underneath this range that I do not want sorted, and this range changes in size. Part of the code is below. This is what I have tried so far with no luck. Range(Selection, Selection.End(xlToRight)).Select Range(Selection, Selection.End(xlDown)).Select vtools

问题 Here goes a yet another SQL question about dates… I'm building a calendaring application using PHP and Postgres that would display events spanning days, weeks or possibly months. Each event has a start date and an end date, and selecting them by range is not a problem; however, it would be useful for me if Postgres could split multi-week events at the first day of each week. I've been told it can be done using GROUP BY and EXTRACT , but I'm not good enough with SQL to understand how. The

问题 I have an xls file that looks this way: http://i.stack.imgur.com/d2fux.png Well, and that's sth like the same piece of info that depends on the headers, in this case the header is the row 22164, next header is 22178, and so on. In the GUI, i have something that let users choose from parameters, and option to load the info from the xls file depending on their choices, for example, they can choose: WR | random | 4 | 6 | 15 looking in that case for the info stored in A22165:O22177 I have already

问题 I have a simple UI picker view in an iOS app (iPhone) and I'm looking to pre-populate it with a range of numbers on launch. What would be the most pragmatic/quickest/optimized way to populate it? I'm new to iOS development, so I'm just starting to test the waters. The documentation is pretty decent but I'd like to get some insight from seasoned developers on the most effective way to accomplish what I'm doing? tl;dr I want to populate a UI picker view with the the number range 45-550 upon the

问题 I have: Foo foo = new Foo(); foreach (i; 0..10) { Bar bar = foo.getBar(i); ... } I want to be able to instead say (equivalently): foreach (bar; foo.getAllBars()) { ... } How do I go about implementing getAllBars() ? I figured something like this: class Foo { auto getAllBars() { return map!(getBar)(iota(10)); } } But you can't do that of course because getBar depends on the this parameter, which will go out of scope. The same applies if you try to create a local function or delegate . I also

问题 I have a database of some 30k ranges, each is given as a pair of start and end points: [12,80],[34,60],[34,9000],[76,743],... I would like to write a Perl subroutine that a range (not from the database), and returns the number of ranges in the database which fully 'include' the given range. For example, if we had only those 4 ranges in the database and the query range is [38,70] , the subroutine should return 2 , since the first and third ranges both fully contain the query range. The problem
