range

问题 Why the result is A:&{[{[{1}]}]}A:&{[{[{2}]}]}A:&{[{[{2}]}]} not: A:&{[{[{1}]}]}A:&{[{[{2}]}]}A:&{[{[{3}]}]} we can't use pointer in range? here is the code, I set a pointer, pointed in the range loop, but it fails. package main import( "fmt" ) type A struct{ Barry []B } func (this *A)init(){ b:=&B{} b.init() this.Barry=[]B{*b} return } type B struct{ Carry []C } func (this *B)init(){ c:=&C{} c.init() this.Carry=[]C{*c} return } type C struct{ state string } func (this *C)init(){ this.state=

问题 I have a datePickerView which I want it to have a min date = current time, max date = 48hrs later. It's currently working fine, as I can't pick out of that range. But there's some aesthetic problems. Some of the period in that range is not in black. For example in the picture below, today's 7hour hand is suppose to be in black but its not. - (void)viewDidLoad { [super viewDidLoad]; NSDate *now = [[NSDate alloc] init]; NSLog(@"now is %@", now); [datepick setDate:now animated:YES]; [now release

问题 I can't seem to find anything on google about this. I know you can pretty much rule out IE. I know webkit supports it but what else do you know? 回答1: At the time of writing, apparently (Desktop) Safari, Chrome and Opera support range inputs, according to Dive Into HTML5. 回答2: Ok, this question has been here quite a while, but I wanted to add this anyway. Regarding a question about browser support, a good source is always the caniuse.com website. In this case, you can find the current, past

问题 I've been playing with some SVM implementations and I am wondering - what is the best way to normalize feature values to fit into one range? (from 0 to 1) Let's suppose I have 3 features with values in ranges of: 3 - 5. 0.02 - 0.05 10-15. How do I convert all of those values into range of [0,1]? What If, during training, the highest value of feature number 1 that I will encounter is 5 and after I begin to use my model on much bigger datasets, I will stumble upon values as high as 7? Then in

问题 I'm trying to list the number of users by age-range: Range : #Users 10-14 : 16 15-21 : 120 22-29 : 312 30-40 : 12131 41-70 : 612 71-120 : 20 I was thinking of creating a static array of hashes: AGE_RANGES = [ {label:"10 - 14", min:10, max:14}, {label:"15 - 21", min:15, max:21}, {label:"22 - 29", min:22, max:29}, {label:"30 - 40", min:30, max:40}, {label:"41 - 70", min:41, max:70}, {label:"71 - 120", min:71, max:120} ] and then use it for my search filter, as well as for my query. But, I

问题 I'm trying to find a way to prevent the user from clicking into the "track" portion of an HTML5 range input. Essentially, I only want the user to be able to use the "handle" to change the range value. Is this even possible? 回答1: It's possible through pointer-events at least on chrome. input[type=range] { pointer-events: none; } input[type=range]::-webkit-slider-thumb { pointer-events:auto; } This will disable clicking on the track and enable clicking only on slider thumbs. 回答2: Adding

问题 I have some javascript that manipulates html based on what the user has selected. For real browsers the methods I'm using leverage the "Range" object, obtained as such: var sel = window.getSelection(); var range = sel.getRangeAt(0); var content = range.toString(); The content variable contains all the selected text, which works fine. However I'm finding that I cannot detect the newlines in the resulting string. For example: Selected text is: abc def ghi range.toString() evaluates to

问题 Background For convenience, I used this alias: typealias Deck = [Int] My needs are expanding so I have now converted my code to: class Deck { var deck : [Int] // ... other members } I am able to delegate most of my calls through to self.deck , but after googling around somewhat, I am still having trouble figuring out how to delegate this call: let deck = Deck() for i in deck[0..<5] { } // <--- PROBLEMS HERE Question How do I implement the delegation of this call? I think it has something to

问题 I’m working on an array of numeric values. I have a array of numeric values as the following in PHP 11,12,15,16,17,18,22,23,24 And I’m trying to convert it into range for e.g in above case it would be: 11-12,15-18,22-24 I don’t have any idea how to convert it into range. 回答1: You have to code it yourself ;-) The algorithm is quite simple: Iterate over the items. Remember the previous item and the start of the range. For each item (except the first one) check: If currentItem = prevItem + 1
