/*
Basic Usage
-----------
0. Configure for:
a. error_text_size in px (defaults 12)
b. error_color - The color of error text (defaults red)
c. error_class - Choose a name that will not conflict with the class that is in use (defaults error_class).
d. error_display_html (defaults true). If you set false, each validation should include the text as value for the key as text. Eg. text: 'something to validate'
e. text_min - minimum text input expected (defualts 2)
f. text_max - maximum text input expected (defualts 50)
g. highlight_all_errors - highlights all the errors together after validation if set to true. If set to false will display one error at a time in sequence as defined (defaults: false)
1. Define an array of validations to be performed
2. For each validation minimum input to be provided should be
a. tagid - tag id of the tag to be validated
b. regex_name - regex to be used for validation
c. text - (optional if config.error_display_html is true, if false, then mandatory)
d. errmsg - the error msg to be shown to the user in case the validation fails for that tag
e. required - if true, tells the engine to verify the empty value too. If false and the value is left empty then it will be considered ok. (default - false)
f. custom_regex - use given regex to the validation
regex_name options
------------------
1. email - checks for validity of email address format
2. exact_x_digits - checks for x digits (mostly used for PINcode, PIN, or Phone number)
a. x_count - number defining the number of digits (e.g. 10) - (defaults 100)
3. any_number - checks for number
- allow_negative - (defaults false). if set true, allows negative numbers
- allow_decimal - (defaults false), if set true, allows to enter decimal numbers
4. text - validates for text containing a-z, A-Z and 0-9
- allow_numbers - you can numbers with text (defaults false)
- other_chars - mention all the charactes you want to allow in a string
- min - minimum string length (defaults 2)
- max - maximum string length (defaults 50)
5. free_text - validates for any free text for it's lenths
- min - minimum string length (defaults 2)
- max - maximum string length (defaults 50)
6. min_number - validates if the entered number is greater than minimum (true) or not (false)
- min - minimum value to be checked
7. max_number - validates if the entered number is less than maximum (true) or not (false)
- max - maximum value to be checked
8. equal - checks if two tags are holding same value or not
- tag2id - tagid of the other input tag
returns true if two strings are equal, else false. Returns false if both the strings are empty
9. filepath - checks if the file selection is done
returns true if a file is selected else returns false. checks for full path, relative path path with font/back slash
[special case]
- namecheck - startswith, endswith, contains, exact, extension
- checkname - the value of the name that should be checked as per the namecheck rule selected
returns true if the namecheck succeeds else false
10. pan_card - Check for validate of PAN card number Format
11. gst_number - Check for validate of GSTIN number Format
-statecode - Check for validate of the selected state code
12. custom - Validate for external given regex as per condition.
- custom_regex - Regex to be check by this.
if developer not provide this field when use custom regex then it will return false.
13. website - Check for validate to website
