====================================================================
Tax Rate Calculated from Income:
1. 10% of amount between $0 - 20,000.00
2. 20% of amount between $20,000.01 - 50,000.00 + 2,000(from line 1)
3. 25% of amount between $50,000.01 - 100,000.00 + 6,000(from line 2) + 2,000
(from line 1)
30% of amount between $100,000.01 - 500,000.00 + 12,500(from line 3) + 6,000
(from line 2) + 2,000(from line 1)
If income is over $500,000 = 1% flat rate on all income. :) The 1%
NOTE: .toFixed(2) ==> forces 2 decimal places
Explained:
Income is your "Gross Income".
To calculate "Net Income" (take home pay):
Tax is subtracted from income.
Income: $500.00
Tax: $50.00
Net Income: $450.00
(see more examples at end of page)
Validate form before calculating and submitting!!!
Do not allow bad data onto the form.
Report any error and allow the user to correct that input.
Put focus where error was detected.
DO NOT clear entire form on error!
Use pseudo-classes to style input boxes
:valid
:invalid
(NOTE these will throw css validation errors - ok)
Do not calculate until all data fields are valid.
Note that calculation is separate from submission
but should occur at the same time.
How?
if ( $(formId).checkValidity() )
{
code to execute if all fields valid
...
}
A checkbox will determine if tax rules are displayed (see example).
if ( $(id).checked)
{
code to execute if checked
}
'Clear' resets all fields to blank (default in drop down).
'Fill' fills all fields to valid values (default in drop down).
USE THIS for form:
target="_blank"
class="someClass"
action="http://www.example.com/review.php"
method="get">
Validation: use html or css to organize the form
