If we want to get an input from user, prompt
method can be used.
<script> function PromptUser() { var yourName = prompt('What is your name?', ''); if (yourName != null && yourName != "") { alert("Your name is [" + yourName + "]"); } } </script> <input type="button" id="btnTest" onclick="PromptUser()" value="Click me!" />
Prompt
