Answer 1

You can use setTimeout for a pause in javascript.

setTimeout(function(){callSample();}, 5000);

then set a global variable inside demo() so that you can identify whether demo() has been called or not and then in

function callSample()
{
    if (variable set)
    {
        sample();
    }
}

Answer 2

Have a look at:

• setInterval
• setTimeout
• clearInterval

Example:

setTimeout(function(){your code here}, 3000)

Answer 3

You can invoke functions after a period of time with setTimeout

setTimeout(demo, 5000);

I'm not sure that I get the "if it is fail to start demo with in 5 seconds" part of your question, because the above code will execute demo() in 5 seconds.

Answer 4

<script language="javascript"> function sample() { alert('sample here'); } function demo() { alert('demo here'); } setTimeout("sample()", 5000); </script> <input type=button onclick="demo();">
