Loop/iterate over dictionary

I created a dictionary as follows and would like to loop over it and perform some actions.

var dict = new ActiveXObject("Scripting.Dictionary");

dict.add("a",1);

dict.add("b",2);

dict.add("c",3);

for (var key in dict){

Log.message("key is "+key+" and value is "+dict[key])

}

But the program does not enter the loop.

How can i iterate over the dictionary in Testcomplete using Jscript?

Hi,

I am not familiar with Dictionary, but I found one example:
//JScript
function ItemsDemo()
{
var a, d, i, s; // Create some variables.
d = new ActiveXObject("Scripting.Dictionary");
d.Add ("a", "Athens"); // Add some keys and items.
d.Add ("b", "Belgrade");
d.Add ("c", "Cairo");
a = (new VBArray(d.Items())).toArray(); // Get the items.
s = "";
for (i in a) // Iterate the dictionary.
{
s += a[i] + "<br>";
}
return(s); // Return the results.
}

It appears that in your code the part to create an array with the needed items is missing.
I've tried to modify your code and here is what I've got:
function DictTest() {
var dict, ar, typeIs, i
dict = new ActiveXObject("Scripting.Dictionary");
dict.add("a", 1);
dict.add("b","2");
dict.add("c","3");

ar = (new VBArray(dict.Items())).toArray()

for(i in ar) {
Log.Message("inside for loop");
Log.Message("the keys are "+ar[i]);
var typeIs = typeof ar[i];
Log.Message("the type of keys is "+ typeIs)
}
}
It looks pretty fine on playback and you can find the results in the screenshot below:

Does it help?
Thanks

  It enters the loop but when it try to access the values it shows up as undefined
  
  var dict = new ActiveXObject("Scripting.Dictionary");
  dict.add("a",1);
  dict.add("b","2");
  dict.add("c","3");
  
  var keys = dict.Keys();
  Log.Message("the keys are "+keys[0]); -----> prints undefined
  var typeIs = typeof keys;
  Log.Message("the type of keys is "+typeIs) -----------> prints undefined
  
  for(var i=0; i<dict.Count; i++){
  Log.Message("inside for loop");
  Log.Message("key is "+keys[i]+" and value is "+sessionsData[keys[i]]); ---------> prints key is undefined and value is undefined
  }

Hi,
I verified this solution: it is bit more convenient:
function ItemsDemo()
{
var a, d, i, s; // Create some variables.
d = new getActiveXObject("Scripting.Dictionary");
d.Add ("a", "Athens"); // Add some keys and items.
d.Add ("b", "Belgrade");
d.Add ("c", "Cairo");
d.Items().toArray().forEach(eachItem => {Log.Message(eachItem)})
d.Keys().toArray().forEach(eachItem => {Log.Message(eachItem)})
}
