Control submit button with Text Entry
I have a requirement, a Submit button initially disabled and get enable when user enter some text into the Data entry field and should disable when we removed the text from that Data entry field. Currently I am able to get that after entering some text and clicking outside that Data entry field and even removed the text from the data entry field and clicking outside the Data entry field.
But my requirement is to get enable the button when we start entering some text in the Data entry field and should disable when we removed the text from the Data entry field by clicking backspace or delete.
Please help me if any one having the solution.
