jQuery selected = selected

I have <select name="users"> ... </select> in file chat_select.php. I refresh this every 8 sekunds to #chatSelect.

This is a refreshing in file chat.php:

var auto_refresh = setInterval(
   function () {

     $('#chatSelect').load('php/refresh/chat_select.php?hodnota='+$('select.user option:selected').val()).fadeIn();

  }, 8000);

What is w开发者_C百科rong? I need that if I choose some value from select that it will be stay (selected=selected).

And what about this?: $("#user option[value=" + val + "]").attr("selected", "selected");

Selected is a property: $('my_select').prop('selected') will set the property "selected" to true.

Save the state of the select box on change by doing

$('#YourSelectBox').change(function() {
    var x = this.value;
    $(this).data('saved', x);
})

Then to retrieve the saved state by doing

$('#YourSelectBox').data('saved')

Note: refreshing the page will clear any data you have saved.

before each refresh, save the current selected option in a variable, and after refresh is done, use jquery to reselect it
