Jquery Add Values To Select Options

I have googled this option for many days but I couldn't find a solution. What I want is: I have two Select Box First Select Box have Country Names Second Select Box is Empty Wha

Solution 1:

Assumption

• You have a script ("/getCities.php") that takes a parameter ("country") that is the ID of the country you want the cities of and outputs JSON that looks like this:

  {"Cities":[{"ID":1,"Name":"New York"},{"ID":2,"Name":"Los Angeles"}]}

  (You can use JSONLint to validate your JSON.)

Then maybe something along these lines:

<selectid="Countries"><!-- omitted --></select><selectid="Cities"></select><scripttype="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script><scripttype="text/javascript">
  $(document).ready(function() {
    // when a new country is selected...
    $("#Countries").change(function() {
      // ...clear existing cities...
      $("#Cities").empty();
      // ...and repopulate cities based on JSON data.
      $.getJSON( "/getCities.php",
      // pass the selected country ID
        {
          country: $("#Countries").val()
        },
        function(data) {
          $.each(data.Cities, function(n, city) {
              // add a new option with the JSON-specified value and text
              $("<option />").attr("value", city.ID).text(city.Name).appendTo("#Cities");
          });
        }
      );
    }); // $("#Countries").change(function() { ... });
  }); // $(document).ready(function() { ... });</script>

Solution 2:

try this.

<scripttype="text/javascript"src="http://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js"></script><scripttype="text/javascript">functionmoveItem() {
        $("#target").append($("#source").find(':selected'));
    }
</script><selectid="source"size="3"><option>option1</option><option>option2</option><option>option3</option></select><buttononclick="moveItem()">Move Item</button><selectid="target"size="3"></select>

Solution 3:

The "cascading dropdown" is such a common interface - I find it hard to believe that you couldn't find any examples. Here's a PHP example that will point you in the right direction.
