jQuery count-- until a specific condition is met

I have explained in a comment where and what I want the code below to do:

$("#run").click(function(){

maxspeed = 1.00;
    if  (maxspeed > 0.07)
        {
            //This is where I want the max speed to countdown at
            //a decrement of -0.01 until it reaches 0.07
        }
开发者_Go百科    else
        {
            delay(3000);
        }

//Code continues below, I will edit post if required

My max speed is already stored in a variable with the value of 0.07. Any help would be appreciated, thanks.

[EDIT] Sorry, I should have explained better. I am pretty new to JS/jQuery and I have no idea how to use a count. I want my function to count down until it reaches a certain value.

Did you try : setTimeout() ? http://www.w3schools.com/jsref/met_win_settimeout.asp

You should use a TimeInterval and start decreasing maxspeed by 0.07

maxspeed -= 0.07;

If you use a loop the action will be instant.

try this

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.5/jquery.min.js"></script>
<script language="javascript">

$(document).ready(function(){

var maxspeed = 1.00;
var decrement = 0.01;
counter(maxspeed,decrement);

});

  function counter(maxspeed,decrement)
  {
    while(maxspeed > parseFloat(0.07))
    {
        maxspeed = parseFloat(maxspeed) - parseFloat(decrement);
    alert(maxspeed);
    setTimeout(counter(maxspeed,decrement),3000);
    }       

  }

  </script>
