I have this fidddle.
It works fine.
When you type a comma in the textbox. It replaces it with comma followed by a space.
In the above example applying the replace to a TextBox with ID of TextBox1
Now here is my other example.
I have 4 text boxes.
How do I apply the replace on every TextBox whose id starts with TextBox1 ?
So the replace should only get applied to the first 3 textboxes.
