$(document).ready(function(){           $("#btnaddmicroelement").click(function(microelement){     alert("clicked");     $("#divverification").append("<div class='clsdivmicroelement'><label>microelement</label><input type='text' class='clstxtmicroelement'/ value=microelement><input type='button' class='clsbtnmicroelmentadd' value='add'/></div>");          return false;   }); });      function getselectedtext(el) {     var sel, range;     if (typeof el.selectionstart == "number" && typeof el.selectionend == "number") {         return el.value.slice(el.selectionstart, el.selectionend);     } else if (             (sel = document.selection) &&             sel.type == "text" &&             (range = sel.createrange()).parentelement() == el) {          return range.text;     }     return ""; }  window.onload = function() {   document.getelementbyid("txtexamplereviewed").onkeydown = function(e) {     if(e.altkey && e.shiftkey && e.which==65){                   $("#btnaddmicroelement").trigger("click",[getselectedtext(this)]);           }   }; }; 

custom parameter comes second argument, have fixed bit code:

 $("#btnaddmicroelement").click(function (microelement, text) {      $("#divverification").append("<div class='clsdivmicroelement'><label>microelement</label><input type='text' class='clstxtmicroelement'/ value="+text+"><input type='button' class='clsbtnmicroelmentadd' value='add'/></div>");     return false; });
