Although the array construction is old style, this page still works. See notes in the script text about changes for JS1.1 and 1.2


Making an array of strings
  1. Declare the array, globally if necessary
  2. Make the array with a user defined function
  3. Enter the value for each array element
  4. Retrieve information as follows:
    • Size of array = strArray.length
    • Any string = strArray[index]
    • Length of any string = strArray[index].length


This function presents an alert box with the strings and their lengths. Strings are made on page load with
  • setUpArray()
which calls
  • strArray = new makeArray(10,'')
and then initializes each of the strings of the array
  • strArray[1] = 'enter strings here;etc'
Notes:
  • See script for makeArray function
  • strArray should be global and declared out side of any function with "var strArray"
function showStringsInAlert()

{
  • var astr = ''
    for (var ii = 1 ; ii<=10 ; ii++)
    {
    • astr += strArray[ii] + ' -- '
      astr += 'length = ' + strArray[ii].length
      astr += '\n'
    }
    alert(astr)
}
Showing an Array of Pictures from Their Names


This function writes an on-the-fly window and uses the strings in the array to retrieve and display gifs.
