how to call functionname within a function

[franksun]

i define a function named add_tag and want to call this function with the jquery function (#example).keypress(). what i hope for is when i input something in the input form with id=example, then the function named add_tag will be executed. I know how to call the function within html, but just want to call it within a function.


$("#example").keypress(function() {
add_tag(event.which)
});

function add_tag(keycode) {
if (keycode == 13) {
var tag = $(event.target).val();
var current = new Date();
var tag_id = "tag" + current.getTime();
var tags = sprintf('<dt id="%1$s" class="tags">%2$s<a href="#" onclick=$("#%1$s").remove()>X</a></dt>', tag_id, tag);
$("#submitted-tags").append(tags);
}
};

like that?

PHP Code:

$("#example").keypress(function(evt) {
add_tag(evt.which)
});

Thank you!

you could even go as far and modify your add_tag() function to make it even more simple.

PHP Code:

function add_tag(evt) 
{
  if (evt.which == 13) {
    var tag_id = "tag" + new Date().getTime();
    $a = $("<a>X</a>").click(function(evt) {
      $(this).parent().remove();
    });
    $td = $("<td/>").attr("id", tag_id).addClass("tags").html($(evt.target).val()).append($a);
    $("#submitted-tags").append($td);
  }
}; 

$("#example").keypress(add_tag);
