jquery keyup delay works, but search value is truncated

Question

This function works (suspends the call) but the search value is not updated. If I enter "hello" the value passed to the function ($(this).val()) is "he". Is there a way to update it the key value so that it passes the whole search?.

$('#search').keyup(function () {

  if ($(this).val().length > 1) {
    var searchthis = $(this).val()

    if (srun === 1 && stimer) {
      if (stimer) {
        window.clearTimeout(stimer)
      }

    } else {
      srun = 1
      var stimer = setTimeout(loadsearch(searchthis), 2000)
    }
  }

})  

loadsearch() sets the var srun to 0;

Apparently, loadSearch is only called once when srun is not set. You should organize your code like this

//put timer outside
var stimer;
$('#search').keyup(function(e) {  
    if ($(this).val().length <= 1) {
        return;
    }

    var searchthis = $(this).val();

    window.clearTimeout(stimer);

    stimer = setTimeout(function() {
        loadsearch(searchthis);
    }, 2000);       
});

setTimeout expect 1st parameter to be a callable function, therefore setTimeout(function(){})

If you put setTimeout(loadsearch(searchthis)) it will execute the loadSearch function directly without waiting for 2s.
