javascript - Append an integer to a string name -


Hi H is trying to iterate for a loop with a long string of words organized in a string (wordlist),

Within effectjs: 

  var wordlist3 = "hellwhentrysthisbreaks" var xc = 3; Var word_length = 4; Var word_ology = 4; For (i = 0; i & lt; words_in_round; i ++) {var num_words = ['wordlist' + xc]. Long / word_labee; Var random = math.flur (math.rendum) * ((num_words + 1) - 0)); N = Math.Round (Random / Term_Labby) * Word_Label; Random_word = (['wordlist' + xc]. Asbestring (n, (n + word_length)) random_words + = random_word; } The code above works if I define the wordlist globally, but when I have not defined it properly local num_words and throws a random word, then in this object There is no method substrings ..  
 My problem is, since I change to local variables when I attach string names and calls. Length This gives me the length of the new name (wordlist3.length = 9) instead of the length of wordlist3 = 20; I can not even call this object based on the method ...   
 
 
  ['wordlist' + Xc] .substring   
 will never work (okay, Unless it happens before another variable, such as.  foo ['wordlist' xc] .substring ). This is because, because in javascript,  [anything]  means an array of "anything", and arrays (described as Kendall) do not have a substrings method. Try  
 
  random_word = (('wordlist' + xc) .substring (n, (n + word_length)) instead   
.

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
