Use jQuery select() to select contents of a div

由 折月煮酒 提交于 2019-11-27 03:36:32
问题 Is it possible to use or adapt jQuery's .select() to set a selection range on the entire contents of a div? I have a div which has a series of labels, inputs, select objects and a couple of other UI elements. I have found code on a separate StackOverflow post with some code hosted on jsFiddle: http://jsfiddle.net/KcX6A/570/ Can this be adapted to select the value of inputs also? Or how would you suggest I go about this? Thanks, Conor Edit: More info I know how to get the value of inputs using

range over character in python

Is there an way to range over characters? something like this. for c in xrange( 'a', 'z' ): print c I hope you guys can help. Ned Batchelder This is a great use for a custom generator: Python 2: def char_range(c1, c2): """Generates the characters from `c1` to `c2`, inclusive.""" for c in xrange(ord(c1), ord(c2)+1): yield chr(c) then: for c in char_range('a', 'z'): print c Python 3: def char_range(c1, c2): """Generates the characters from `c1` to `c2`, inclusive.""" for c in range(ord(c1), ord(c2)+1): yield chr(c) then: for c in char_range('a', 'z'): print(c) import string for char in string

Array of indexes to array of ranges

由 跟風遠走 提交于 2019-11-27 02:19:31
问题 Ranges in ruby are pretty cool. I end up with arrays such as this: geneRanges = [(234..25), (500..510), (1640..1653)] And subsequently have to remove bits of them. For that I: genePositions = geneRanges.collect {|range| range.entries }.flatten => [500, 501, 502, 503, 504, 505, 506, 507, 508, 509, 510, 1640, 1641, 1642, 1643, 1644, 1645, 1646, 1647, 1648, 1649, 1650, 1651, 1652, 1653] They get manipulated, so some numbers get excluded, and others may be added. I may end up with this: [505, 506

SQLite loop statements?

由 南楼画角 提交于 2019-11-27 02:11:36
问题 Is there any loop statements in SQLite like FOR .. in .. LOOP or something like that? I have two columns StartRange, EndRange and I need to insert whole sequence in other table. So if StartRange is 1 and EndRange is 3 it's necessary to make three inserts with value, contains 1, 2, 3 . 回答1: You can do this sort of thing in straight SQL if you have an extra table that holds all the integers that you need. Suppose your StartRange and EndRange range between one and ten and you have a table like

Only index needed: enumerate or (x)range?

由 穿精又带淫゛_ 提交于 2019-11-27 02:07:42
If I want to use only the index within a loop, should I better use the range/xrange function in combination with len() a = [1,2,3] for i in xrange(len(a)): print i or enumerate ? Even if I won't use p at all? for i,p in enumerate(a): print i I would use enumerate as it's more generic - eg it will work on iterables and sequences, and the overhead for just returning a reference to an object isn't that big a deal - while xrange(len(something)) although (to me) more easily readable as your intent - will break on objects with no support for len ... That's a rare requirement – the only information

Range as dictionary key in Python

问题 So, I had an idea that I could use a range of numbers as a key for a single value in a dictionary. I wrote the code bellow, but I cannot get it to work. Is it even possible? stealth_roll = randint(1, 20) # select from a dictionary of 4 responses using one of four ranges. ## not working. stealth_check = { range(1, 6) : 'You are about as stealthy as thunderstorm.', range(6, 11) : 'You tip-toe through the crowd of walkers, while loudly calling them names.', range(11, 16) : 'You are quiet, and
