Example 1
<cfscript>
empArray = ["awdhesh", "kumar", "agrawal"];
listS = "'awdhesh', 'kumar', 'agrawal'";
ArrayEach(empArray, xclosure);
ListEach(listS, xclosure);
function xclosure(empname, index)
{
writeOutput(empName & " at index: " & index);
}
</cfscript>
Also, the original array can also be passed to the closure function. So the following code is also valid:
...
function xclosure(empname, index, empArray)
{
}
...
<cfscript>
cityList = "San Jose,New york, Boston, Las Vegas";
function printCity(String city)
{
writeOutput("<br>Current city: " & city);
}
ListEach(cityList ,printCity);
</cfscript>
