/*
* Name : theValidator
* Purpose : To add client side validations on form fields
*
* The parameters
* 0) theform - The instance of the form , use 'this' rather than name
*
* 1) thecontrols - The name of the controls separated by comma, only add name of controls which you want to be validated.
*
* 2) themessages - The Message i.e if you write Name, then the msg would be 'Name cannot be blank.'
*
* 3) theNumeric - If you want any control to be validated for numeric value, then specify 'Y' 
*    exactly in the same order if the 1st parameter has values Input1,Input2,temp,.. 
*	 if you want to validate the Input2 control for numeric value the ,Y,,....
*	 The input value must be less than or equal to 0.
*
* 4) theEmail - For validating correct form of email address
*
* 5) theURL - For validating correct form of URL i.e. http://www.domain.com/
*
* 6) theConfirmPassword - If the form contains a password and a confirm password field 
*	 then add a 'Y' against the confirm password control, the script will match its value with the
*	 password field and if they doesn't match will return false.
*
* 7) thebadstuff - To check for the special characters, if present then it returns false
*	 It works for three conditions means - 
*
*	 if we specify 1 against the control in the thebadstuff variable e.g. thebadstuff=",,,,1,,,";
*	 then the script will check for these special characters "~`!@#$%^&*()=+|<>?;:/\"\\"
*
*	 if we specify 2 against the control in the thebadstuff variable e.g. thebadstuff=",,,,2,,,";
*	 then the script will check for these special characters "~`!@$%^&*()=+|<>?;:/\"\\" (no hash sign present)
*
*	 if we specify 3 against the control in the thebadstuff variable e.g. thebadstuff=",,,,3,,,";
*	 then the script will check for these special characters "~`!@$%^&* ()=+|<>?;\"" in this the script
*	 checks for the (space as well)
*
* 8) theinteger - Same as numeric except it check that the value entered must be greater than 0
*
* 9) thepercent - It checks for the percentile value which must be between 0 to 100
*
* 10) thesize - If you want to have a maxlength check on any input type then specify the maxlength value
*	  against that control for e.g say we have
*	  thecontrols=text1,text1,textarea1,textarea2;
*	  and we want to have a size control on textareas then we will enter sizes as below
*	  thesize = ,,500,1000;
*	  NOTE: But it has a drawback it lets user enter the number of chars he wants and when user submits
*	  the form then it checks the size which creates problem, you should use function textCounter(field,maxlimit)
*	  instead (specified later).
*
* 11) thedecimal - If you does not want that user should enter decimals in a particular field
*	  then specify 'Y' against that control.
*	  NOTE: Make sure you are using this check for fields in which you are entering numeric values
*	  else it will not allow you enter "." i.e. fullstop 
*
* 12) theimage - This parameter is used to add checks on file uploading control i.e. input type="file"
*	  This javscript check enables the system to check on client side that which type of file is getting
*	  uploaded. 4 types of variations has been implemented till now means 4 types of file type checks has
*	  been implemented. They are as follows:
*
*	  If we want to add a check for simple images then write Y against the controls i.e. It will allow files of types
*	  .gif, .jpg, .jpeg
*	  theimage=,,Y,,Y;
*
*
*	  If we want to add a check for text files then write C against the controls i.e. It will allow files of types
*	  .txt, .doc, .pdf
*	  theimage=,,C,,C;
*
*
*	  If we want to add a check for both images and text files then write YC against the controls i.e.
*	  It will allow files of types  .gif, .jpg, .jpeg and .txt, .doc, .pdf as well
*	  theimage=,,YC,,YC;
*
*
*	  If we want to add a check for movie files then write M against the controls i.e.
*	  It will allow files of types  .mpg, .mpeg, .avi, .mov, .rm, .wmv, .asf
*	  theimage=,,M,,M;
*
* 13) theempty - In this parameter Y against the specified controls will not allow user to leave those
*	  fields empty/blank, it works for textbox, textarea, selectbox, file upload.
*
* 14) themin - If you don't want that a user should enter value less than some specified value then you
*	  must enter that value against that control in the "themin" variable list. Say we are implementing
*	  a check on user's bidding for some product and his bidding must be greater than 100 then you must
*	  specify 100 against that control e.g.
*	  themin=,,100,,,;
*
* 15) themax - If you don't want that a user should enter value greater than some specified value then you
*	  must enter that value against that control in the "themax" variable list. Say we are implementing
*	  a check on user's age that it must not be greater than 120 then you must
*	  specify 120 against that control e.g.
*	  themax=,,120,,,;
*
* 16) thecheckboxlength - You can implement this functionality where you have a group of checkbox/radio
*	  with same name and you can specify the number of the checkboxes or radio buttons and you want that 
*	  user must select any of these checkboxes. Then you can implement it like this e.g.
*	  theControl="vchMemFirstName,vchMemLastName,vchMemEmail,vchMemDoc,chkIndustry[]";
*	  thecheckboxlength=",,,,<?=fnCountRow('iaba_IndustryMaster','1');?>";
*	  OR
*	  thecheckboxlength=",,,,7";
*	  
*
* 17) thephoneno - This is the most commonly used parameter, if you specify 'Y' against any control in this
*	  parameter then the script will allow user to enter phone numbers in following formats:
*	  xxx-xxx-xxxx , (xxx)xxx-xxxx , xxxxxxxxxx (10 digited Mobile no), xxxxxx (6 digits no), xxxxxxx (7 digits no)
*	  and xxxxxxxx (8 digits no)
