A Simple Form Validation Script
The Javascript Form Object Properties and Methods can be used to Validate the Html Form.The Multiple Forms in the Html Page are Held as Forms Array.The Javascript Forms Array also holds Information about each Object within the Form tag.
The Multiple Forms in the Html page can be accessed by refering to its Array Index. document.forms[0] refers to the First Form in the Html Page.Similarly the Elements within the Form Tag can be accessed by refering to the elements Array Index. document.forms[0].elements[0] refers to the First element in the First Form in the Html Page.
In the Above Example,the function 'validateForm()' has two loops.The first loop runs thru all the elements in the form and if it encounters any empty elements it append the field name to the message.The Second loop runs thru all the form elements and alerts the user to fill the empty field.
