Question

I’m working on an ASP.Net webpage which will use the jQuery Dropdown Checklist (http://code.google.com/p/dropdown-check-list/). I’m fairly inexperienced with JavaScript and completely new to jQuery.

Could anyone help me with a JavaScript function that de-selects items from a jQuery DropdownChecklist? It would need to accept a string, then de-select the item that matches that string.

Thanks in advance.

Try changing the original <select> element so that the item you want to deselect is no longer selected and then refresh the jQuery dropdown-checklist using the “refresh” command. Something like this (where selectID is the ID of the original <select> element and targetString is the content of the <option> you want to deselect):

function deselect(selectID, targetString){
  $("#"  + selectID + " option").each(function(){
      if($(this).text() === targetString) $(this).attr("selected", "");
  });
  $("#" + selectID).dropdownchecklist("refresh");
}
