问题 I'm trying to figure out, how to find equal sub-string in big list of strings. This method works fine: var results = myList.FindAll(delegate (string s) { return s.Contains(myString); }); But it also looks for sub-string with part of word, for example, if I'm looking for "you do" it founds also extra "you dont" because contains "you do.." In case of string, this method seems gives desired result: bool b = str.Contains(myString); if (b) { int index = str.IndexOf(myString); } How to get same

问题 I've been trying to hide divs that contain particular string using the other solutions suggested on this site, however none worked (most likely due to my inexperience with jQuery) I'd like to completely hide all divs that (in this example) contain the string 'zynthesized' <div class="photos-wrapper" id="detailPhoto-977355202965894535_11842652"> <div class="pseudo"> <a href="#/user/11842652/">zynthesized</a> </div> <div class="image-wrapper"> <a href="#/detail/977355202965894535_11842652"

问题 I am new to JQuery and maybe am missing the obvious, but how can I filter a table using the contains selector but have it look for multiple strings using an OR operator. In other words, I would like rows containing "Red" OR "Yellow" to be hidden. So far I have this which works by hiding all rows except the given date: $(function() { $('div#WebPartWPQ5 table.ms-summarycustombody tr:not(:contains("10/27/2009"))') .hide(); }); As added challenge, what I am really trying to do is write a hidden

问题 so I'm having a problem with my contains method in beta 5. specifically it says it is unavailable when using this code: class func createSlot(currentCards: [Slot]) -> Slot { var currentCardValues:[Int] = [] for slot in currentCards { currentCardValues.append(slot.value) } var randomNumber:Int = Int(arc4random_uniform(UInt32(13))) while contains(currentCardValues, randomNumber + 1) { randomNumber = Int(arc4random_uniform(UInt32(13))) } Any help would be appreciated, not sure if it is a problem

问题 I tried looking through some of the other questions, but couldn't find any that did a partial match. I have two List<string> They have codes in them. One is a list of selected codes, one is a list of required codes. The entire code list is a tree though, so they have sub codes. An example would be Code B Code B.1 Code B.11 So lets say the Required code is B, but anything under it's tree will meet that requirement, so if the Selected codes are A and C the match would fail, but if one of the

问题 my initial dataframe looks like this A | B ----------------- 'a' | ['1', 'a', 'b'] '1' | ['2', '5', '6'] 'd' | ['a', 'b', 'd'] 'y' | ['x', '1', 'y'] and I want to check if 'a' is in the corresponding list in B: ['1', 'a', 'b'] I could do that by using the apply df.apply(lambda row: row[['A']][0] in row[['B']][0], axis=1) that gives me the expected result: [True, False, True, True] but on the real data I have (millions of rows) that is very heavy and takes ages. Is there a more efficient way
