Keyup affect the typing in textbox in browser when i send the request. are this possible to stop affect?

Question

in a webpage i have a textbox where user type something and get the result as change the content through ajax request response.

because if i type faster then response maybe late then typing so it' make typing speed slow.

are this possible to stop affect these kind of problem.

Answer 1

to guard against this i usually do something like:

var to = null;
$('input').keyup(function()
{
    if(to!=null)
    {
        clearTimeout(to);
        to = null;
    }
    to = setTimeout(function()
                    {
                       // do my stuff here
                       to = null;
                    },200); 
});

it waits 200 milliseconds after the last keyup before making the request, if a new keyup occurs the timeout is reset.
