The following code works fine. When I click the "Test Play/Stop" button a series of points from the 'geojson' list are drawn with popup attributes one by one. The time interval is defined by the variable timeGap.

How I can put an option for user to enter his/her timeGap value?

One example using jQuery. You would need to integrate with your existing script; maybe keeping a default timeGap of 5000 (in case the user doesn't enter one), but overwriting that with the input value if the user clicks the submit button. You could also trigger this with the play button, grabbing the value from the input if it exists.

<script src="http://code.jquery.com/jquery-1.11.3.min.js"></script>
<input id="time" type="text" placeholder="Enter a time gap" style="float:left; margin-right:5px; padding-left:3px;" />
<button type="button">Submit</button>

<script>
var timeGap = 5000;
$('button').click(function() {
    timeGap = $('input#time').val();
})
</script>
  • But why the input text box and 'Submit' button are outside the screen area? It is reasonable that the input box and Submit button should be visible only when the user clicks 'Test Play/Stop' button' (before the action takes place) and clear away on next click on 'Test Play/Stop'. And the input box should be visible somewhere on top of map area. Any solution, please? – Suresh Man Shrestha Jul 11 '15 at 5:40
