jquery - How to have one member of a javascript object refer to another member of same object? -


this question has answer here:

while defining object in javascript, there way member of object access value of member of same object? example if defining below (using jquery)

var x = $.extend({}, {   greeting: 'hello',   message: this.greeting+' world' });  alert(x.message);

this above code alert undefined world. how make take value of greeting during definition. in case expected output hello world.

you can use properties:

var foo = {     greeting: 'hello',     message() {         return this.greeting+' world'     } };  console.log(foo.message); foo.greeting = 'hi'; console.log(foo.message);

although i'm not sure how these interact $.extend

in older browsers, make message function, rather property getter

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
