Modify Array

Demonstrates how to modify an array by adding elements to or remove elements from the array. Our example also includes validation to ensure that only valid elements are removed or that 'reasonable' element indexes are added. Clever!

Simply click inside the window below, use your cursor to highlight the script, and copy (type Control-c or Apple-c) the script into a new file in your text editor (such as Note Pad or Simple Text) and save (Control-s or Apple-s). The script is yours!!!

  <HEAD> <SCRIPT LANGUAGE="JavaScript"> <! > <! >  </script> </HEAD>  <BODY> <center> <form name=form> <input type=button value="Show Array" onClick="javascript:showArray(letterArray)"><br> <input type=button value="Add Element" onClick="javascript:addElement(letterArray)"> <input type=button value="Delete Element" onClick="javascript:deleteElement(letterArray)"><br> <br> <textarea name="text" rows=20 cols=60></textarea> </form> </center>
