I saw this example
When you run it, it looks like this. So the textbox has the value Hello.
Now I type the word World in the textbox and click outside the textbox which fires the onchange event like this.
Is there a way to store the existing value of the textbox in a hidden field and also store the new text i typed in the textbox in a hidden field also, but separately.
So when I run the above example and then type World.
I want to store the existing value which is "Hello" in a hidden field called HiddenField1
and the new text that I typed in the textbox which is "World" in a hidden field called HiddenField2
What's the best way to do that?
