Selecting text for easy copying

 //Get Exising Select Options    
 $('form#product select').each(function(i, select){
    var $select = $(select);
    $select.find('option').each(function(j, option){
       var $option = $(option);
       // Create a radio:
       var $radio = $('<input type="radio" />');
       // Set name and value:
       $radio.attr('name', $select.attr('name')).attr('value', $option.val());
       // Set checked if the option was selected
       if ($option.attr('selected')) $radio.attr('checked', 'checked');
       // Insert radio before select box:
       $select.before($radio);
       // Insert a label:

Selecting text for easy copying

 var textNode = document.getElementById('IdOfNodeToBeSelected');
 if (document.selection) {
   var range = document.body.createTextRange();
   range.moveToElementText(textNode);
   range.select();
 } else if (window.getSelection) {
   var selection = window.getSelection();
   var range = document.createRange();
   range.selectNodeContents(textNode);
   selection.removeAllRanges();
   selection.addRange(range);	
 }

Building multiselect values from existing services

In the following example the field TERRITORY has autocomplete wuth Country values. Output format example: "Denmark, Finland, Sweden"

 function split( val ) {
    return val.split( /,\s*/ );
 }
 function extractLast( term ) {
   return split( term ).pop();
 }
 $(function() {$("#DATA_TERRITORY").autocomplete({
       source: function( request, response ) {
         $.getJSON( "autocomplete?type=dk.p2e.blanket.form.fields.ajax.FieldAjaxCountry&subtype=0", {
           term: extractLast( request.term )
         }, response );
       },
      autoFocus: true, 
      min_length: 2, 
      delay: 300, 
       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;
       }
 });});

Redirecting non administrators away from list views

 var params =  window.location.href.split("?")[1];
 if( params == "SagID=251&command=list" ) {
   if( ! $( "#TempusServaPage" ).hasClass( "IsAdministrator" ) ) {
     console.log("redirecting to main from list");
     window.location.href = "main";
   }
 }
