jquery - Hide All But First Matching Element -

-

I am using jquery to sort through several paragraphs. Currently I have to show it only paragraph which starts with the current letter. But now, I would like to strengthen further. If there are many instances in the text between the paragraph tags, then I would like all of the hidden first.

It is so close to me, but it is not working. 

  Var characters = '& lt ;? Php echo (strlen ($ _ GET ['letter']) == 1)? $ _GET ['Letter']: ''; ? & Gt; 'Function Finish () {jQuery (' P '). Each (function () {if (jQuery (this) .text (). Substr (0,1) .toUpperCase () == letter} {jQuery (this) .addClass ('current-series'); jQuery (this) HTML (letter + '& lt; span class = "hidden" & gt;' + jQuery (this) .text (). Piece (1) + '& lt; / span & gt;');} Other {jQuery (This) .hide ();}}}}

Update:

Sorry, it's hard to know that this link Here's a basic example:

  • The selected letter B
  • The returned values ​​are:

the ball

< P> Ball

Ball

Brain

Bats

Bats

In each of these Paragraph tags of

boy

brain

bat

It will hide everything, but the first paragraph with the first letter:

Edit: You can solve the following messy. 

  function (Finnish) {var found_first = []; JQuery ('P'). Each (function () {if (jQuery (this) .text (). Substr (0,1) .toUpperCase () == letter) {if (found_first [jQuery (this) .text)]! = True) {jQuery (this) .addClass ('current-series'); Found_first [jQuery (this) .text ()] = true;} and {jQuery (this) .hide ();}} else {JQuery (this) .hide ();}}}}

windows - Heroku throws SQLITE3 Read only exception -

After I deploy the app to Heroku, I have to run migration scripts and get this error message ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init ' how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads. I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -

I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java The input to the lexical analyzer is a .tex file that is of the following format. \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document} The output of the lecture may be a table of contents with a page number in another file. 1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of Language Analysis Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning. I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -

-
I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly. For example, my keys are like this: '1', '101', '11' and I may need them: '001', '101', '011' What is doing, but I know that there is a better way tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction. for sorted (D, key = int): print '% s:% R'% (k, d [k]) < / Div>
