This is a noob question but I hope you can help. I have a table of reference data (places, events, people etc) that I want to associate with a table of images. When cataloguing the image I want to use autocomplete to associate the image with pre-existing entries in the "wiki" like table. Here is the autocomplete code that works to populate a list of references. What I want to do is upon save add a reference in a bridge table so that image_id,wiki_id is created. Similarly, upon removal of the tag, the reference is disassociated. I will probably work it out but I am looking for best practice advice here.

Many thanks,

J

$(function() { function split( val ) { return val.split( /,\s*/ ); } function extractLast( term ) { return split( term ).pop(); }

$( "#wikitags" )
  // don't navigate away from the field on tab when selecting an item
  .bind( "keydown", function( event ) {
    if ( event.keyCode === $.ui.keyCode.TAB &&
        $( this ).data( "ui-autocomplete" ).menu.active ) {
      event.preventDefault();
    }
  })
  .autocomplete({
    source: function( request, response ) {
      $.getJSON( "/ajax/wikiSearch", {
        term: extractLast( request.term )
      }, response );
    },
    search: function() {
      // custom minLength
      var term = extractLast( this.value );
      if ( term.length < 2 ) {
        return false;
      }
    },
    focus: function() {
      // prevent value inserted on focus
      return false;
    },
    select: function( event, ui ) {
      var terms = split( this.value );
      // remove the current input
      terms.pop();
      // add the selected item
      terms.push( ui.item.value );
      // add placeholder to get the comma-and-space at the end
      terms.push( "" );
      this.value = terms.join( ", " );
      return false;
    }
  });

});
