my requirement as below:
1: Don't display the underline and thousand-separator when the text box is focused
2: If the number typed is bigger than one thousand, it will fill thousand-separator automatically (the text box is still being focused).For example, if I type in 123,then it displays as 123.00;then I input the fourth number 7,I want it displays as 1,237.00 immediately(not only after the text box lost focused). it's important that keeping then cursor position be after the number 7.
3:when the entire content is selected and I delete it,the value of the the text box should be zero and displays as 0.00
many thanks
