function get_selection() {
    var txt = '';
    if (window.getSelection) {
         txt = window.getSelection();
    } else if (document.getSelection) {
         txt = document.getSelection();
    } else if (document.selection) {
    txt = document.selection.createRange().text;
    }

 }

 $(document).on("pagecreate","#pageone",function(){

 $(document).on("taphold",function(e){
     var select_text = get_selection();
     alert(select_text);
 });
