JavaScript arrays: combining and splitting

This series of articles mainly concentrates on working with JavaScript arrays. This is the second article in the series and mainly concentrates on working with arrays effectively. You can reuse these scripts for injection into server side controls easily (especially in .NET and Java).

            </form>|
      </body>
</html>

In the above code, I worked with a sample string as follows:

var SimpleString = " This is the second example";

From the above statement, we can easily determine that the “separator” for the elements would be “ ” or a space. Proceeding further we have the following:

var myArray = SimpleString.split(" ");

Make sure that you identify the space within the “split” function. The above statement makes the string to split into several elements, based on the separator “ ” (space). Once the splitting is completed, it creates an array of those elements and assigns the same to the variable “myArray”. We use the following loop to display all the elements (as explained in my first article):

      for (var i = 0; i < myArray.length; i++)
      {
            document.write(myArray[i] + "<BR>");
      }
