JavaScript function call at the end of a button click event

Question

How do you call a JavaScript function at the end of a button click event in code?

Answer 1

If you are working in .NET, you can try

ScriptManager.RegisterClientScriptBlock(myButton, this.GetType(), "BlockName", "alert('hello world');", true);

Answer 2

You probably need the onmouseup event:

<button onmouseup="alert('You release the mouse button!')">Click me</button>
