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?
Champion Level 2Hi,
Try
for (var key in dict.keys)
Does it help?
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
}
AlumniHi,
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
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)})
}
