CISC103, Fall 2006, JavaScript Example

This version is broken

• When pulling a numeric value out of an input element in a form, we should use parseInt() or parseFloat ()
  • But here we didn't do it!
  • See page variableExample.02.html for a corrected version that includes the call to parseFloat()
• The data returned by the value attribute of the price object has the string data type.
• Therefore, all the other values get a string data type
• Therefore, when we do the + operator to add the tax and the purchasePrice, we get string concatenation instead of addition.
