//---------------------------
//    Java Mask Control
//
// v 1.0 awi 29/05/2006
//
//*** 1. HTML Control must have name,id and have to fix maxlength (maxlength=all of character)
//*** 2. Fill style="text-align:right" if you wish to use right to left style
//*** 3. for like currency control please use textbox.defaultValue to calulate NOT use textbox.value
//***    then use function _SetCurrencyValue(textbox,iValue) to set it.
//*** 4. for more mask sign, please use '|' for seperate each mask sign.
//*** 5. for currency mask style if you want thousand deliminator, just  add true value in kilo parameter
//------------------------------------------------------
//For Bank acount, Date ,Time and Percent ....etc
//icheck parameter available with
// - 'ibank'
// - 'idate'
// - 'itime'
// - 'ipercent'  //SPA Request valid value 0% - 100%
// - 'iMultiple' //MTR request on Sep5,2006 for fullfill value format
// - ...
//------------------------------------------------------
//You have to put at least 3 event with 
//1.onpaste
//2.onkeypress
//3.onkeyup
//OPTIONAL onblur
//------------------------------------------------------
//By example with Bank account Control:  *_mask function
//------------------------------------------------------
//<input type = "text" name ="bank1" id ="bank1" onkeyup="javascript:return _mask(this,'4,12','-',event);" 
//onkeypress ="javascript:return _keypressed(event,this);" onpaste="javascript:return _bpaste(event)" 
//onblur="javascript:return _CheckLost(this,'ibank','-','Invalid Bank Account');" maxlength="14" size="13">[###-#######-##]
//1. onkeyup="javascript:return _mask(this,'4,12','-',event);" call function _mask(textbox,loc,delim,e,icheck) So
//	 - textbox = this (HTML control)
//	 - loc = '4,12' (position of deliminators seperate by ',' for more one)
//	 - delim = '-' (deliminator sign seperate by '|' for more one)
//	 - e = event (windows event) 
//	 - icheck = blank (is OPTIONAL parameter for check value is valid or not when press anykey)
//2. onkeypress="javascript:return _keypressed(event,this);" call function _keypressed(e,textbox,Currency)
//	 - e = event (windows event) 
//	 - textbox = this (HTML control)
//	 - Currency = blank (is OPTIONAL parameter for check some key use in currency)
//3. onpaste="javascript:return _bpaste(event)" call function _bpaste(event)
//	 - event = event (windows event) 
//4. onblur="javascript:return _CheckLost(this,'ibank','-','Invalid Bank Account');" call function _CheckLost(textbox,icheck,delim,message)
//**** is OPTIONAL event
//	 - textbox = this (HTML control)
//	 - icheck = 'ibank' (check value is valid for bank account)
//	 - delim = '-' (deliminator sign seperate by '|' for more one)
//	 - message = 'Invalid Bank Account' (your message to show when it's invalid value.) IS OPTIONAL parameter
//------------------------------------------------------
//By example with Currency control:	*_maskDigit function
//------------------------------------------------------
//<input type = "text" name ="Curr1" id ="Curr1" onkeyup="javascript:return _maskDigit(this,'2',',',event,true);" 
//onkeypress ="javascript:return _keypressed(event,this,true);" onpaste="javascript:return _bpaste(event)" 
//maxlength="10" size="13" style="text-align:right">[#######,##]
//1. onkeyup="javascript:return _maskDigit(this,'2',',',event,true);" call function _maskDigit(textbox,detail,delim,e,kilo)
//	 - textbox = this (HTML control)
//	 - detail = '2' (digit number after deliminator sign)
//	 - delim = ',' (deliminator sign can be ',' or '.' or etc..)
//	 - e = event (windows event) 
//   - kilo = true (want thousand deliminator)  IS OPTIONAL parameter
//2. onkeypress ="javascript:return _keypressed(event,this,true);" call function _keypressed(e,textbox,Currency)
//	 - e = event (windows event) 
//	 - textbox = this (HTML control)
//	 - Currency = true (is OPTIONAL parameter for check some key use in currency)
//3. onpaste="javascript:return _bpaste(event)"  call function _bpaste(event)
//	 - event = event (windows event) 
//**** if have >> onblur="javascript:return _CheckLost(this,'ipercent','.','Invalid Percent');"
//4. onblur="javascript:return _CheckLost(this,'ipercent','.','Invalid Percent');" call function _CheckLost(textbox,icheck,delim,message)
//**** is OPTIONAL event
//	 - textbox = this (HTML control)
//	 - icheck = 'ipercent' (check value is valid for percent)
//	 - delim = '.' (deliminator sign seperate by '|' for more one)
//	 - message = 'Invalid Percent' (your message to show when it's invalid value.) IS OPTIONAL parameter
