问题 Is it possible to find or add an element in one step in a Javascript Map? I would like to do the following in one step (to avoid looking twice for the right place of the key): // get the value if the key exists, set a default value otherwise let aValue = aMap.get(aKey) if(aValue == null) { aMap.set(aKey, aDefaultValue) } Instead I would like to search for the key only once. In c++, one can use std::map::insert() or std::map::lower_bound() In javascript the code could look like this: let

问题 I am trying to get the text inside a specific div in a server response. I used Firebug to see what the response was, and I can see my element in the returned code, but for some reason I can get jQuery to capture it. Here is what I am using: var response = $('<div />').html(serverData); $('#uploadedFiles').html($(response).find("#created").text()); alert($(response).find("#created").text()); Trying that just returns nothing, not text or anything. Am I doing this correctly? Note: The server

问题 Why does this command work: /home/user1/tmp $ find ./../.. -wholename '.*/tmp/file.c' -exec echo '{}' \; ./../../user2/tmp/file.c /home/user1/tmp $ And this command does not work? (finds nothing) /home/user1/tmp $ find /home -wholename '.*/tmp/file.c' -exec echo '{}' \; /home/user1/tmp $ 回答1: The first command generates file names starting with ./../.. . Thus the wholename pattern will match because they start with . . The second command generates filenames starting with /home . However, the

问题 I have a folder with a couple thousand files and I want to move them into subfolders according to a string in the filename.

问题 Inside a cell I need to access the TreeOptions model. So I've wrote this : $this->loadModel( 'TreeOptions' ); $i = $this->TreeOptions->find( 'all' ); But when I do the foreach like this : foreach( $i as $row ) debug( $row->description ); It only returns the last record of the result. The only way I've found to make it work as desired is adding the limit clause : $i = $this->TreeOptions->find( 'all', [ 'limit' => 200 ] ); And then, I can get the whole set of records. What am I missing ? Thanks
