node.js - Are variables defined in the global context accessible when there's name collision? -

-

If I want to define a variable, define the global context from within an area where already equal A variable with the name exists: 

  var variable = 'value'; Function someScope (variable) {variable = 'this not'; Var global = function ('return it') (); Console.log ('this & gt;', global.variable); }   
 Can still reach any kind of global expanse?  
 Neither the  global  object nor the works. ( global.variable  returns are undefined)  
 
 
 
 if the variable is actually global It's global Can access through the name, even if there is a collision with a local variable. For example  
  // notice is not "var" here variable = 'global'; Function someScope () {var variable = 'local'; Console.log (variable); // local console.log (global.exchangeable); // global} someScope ();   
 However, if you define your variable with "var" at the top of the file (as you are in your code) then it will not be global and you will get different results Meetings (i.e. Global.Variable Print Undefined.)

I have a requirement whenever I run my own kettle, dynamically took database connection parameters from an excel source Every run should go. I have an Excel column names: hostname, username, database, password. I want to pass these connection parameters to my table input stage dynamically whenever it runs the job. This is what I was trying to do. You can get it Connection parameters from the DB reading source (for example Excel or a CSV file in my example) < / Li> Store the parameters in the variable Using the variable in your connection's settings. Setting Variables Create another conversion for (you can not do it in the same conversion Uses): set variables element variable: The element that reads / writes your data creates a new connection and sets the connection parameter using $ {variable name_} Note that you will need to type in the field field in the field $ {password} Also keep in mind that this can be a security problem as the

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ... " , Status {console.log ("open site:" + data [index B], position); / * OLD * / indexB ++; page evaluation (function () {// page scrape and an object Return}, function {console.log (result.dataRequest); // here is the problem}); / * new and fixed * / indexB ++} first console Logs it: Open Site: 100 Success Opens Site: 101 Success B Ola Site: 102 Success Opening Site: 103 Success Opened Site: 104 Success Which is good. Data is verified in scrap HTML and from index to array Matches. So in page 101 I scrap '101 and retrieve' and pu
