Question

Answer 1

A:

$('#example-placeholder').load("loadres.php?show=" + $('#box option:selected').val());

This will use jquery to get the selected value from the drop down list and append it to the URL as a querystring parameter, which you can access in the loadres.php page.

This sample seems to work than others, but the issue I am facing now is if I try to pass parameters using `+`, when I try to capture it in the results page, I am not getting the `+` sign. Any idea why it is getting stripped off?Ex : `loadres.php?show=one+two+three`

You need to understand URL character encoding.Take a look at this: http://www.permadi.com/tutorial/urlEncoding/

Answer 2

+3 A:

You should use the $.ajax() method from jQuery. you can pass data to the url and have a callback at the end.

$.ajax({
  url: 'loader.php',
  data: 'somedata',
  type: 'GET',
  success: function(data){
    $('#example-placeholder').text(data);
  }
});

This will do the trick. This method also provides far more flexibility. You can have different functions such as error functions and complete functions.

Answer 3

A:

similar to saif-bechan's post you can use ajax with post and data can hold an object to pass multiple parameters

    $.ajax({
        type:"POST",
        url: loadres.php,
        data: {
              foo:'bar',
              selected:$('#selector').val()
        },
        dataType: 'json',
        error: function(data) {
                   //error code here
        },
        success: function(data) {
                      //success code here
        }
    });

I will also note that is is better to put your click event in jquery context not in the html

so in script somewhere use

 $('#button_id').click(function(){
       //call to ajax
 };
