詳細
The SelectionStart property is the character position that selection begins within the text.
If the cursor is to the left of the first character, the value will be 0.
The most common requirement for Selection handling is completing a value during input.
SelectionStart is provided for completeness and is unlikely to be required for most development purposes.
