first page

<button onclick="refereceid_transfer()">try it</button>  <script>   function refereceid_transfer() { alert('test'); var referenceid = "jggd154278"; referenceid = btoa(referenceid); //sessionstorage.setitem("sent", referenceid);   window.open("second.jsp", "_blank", "toolbar=yes,scrollbars=yes,resizable=yes,top=500,left=500,width=400,height=400"); }  </script> 

second page

<p id="s1"></p>  <script> $(document).ready(function(){   // var = sessionstorage.getitem("sent",id); alert(a); });   </script> 

i need pass reference id 1 window window. tried use session storage , local storage pass variable , have failed in both condition. there new suggestion can pass reference id new window.

thanks

you can try localstorage this.

add item want pass on page:

localstorage.setitem("key", "value"); 

on page can access through:

localstorage.getitem("key"); 

you can store object data in localstorage. note clear localstorage if you're storing sensitive information.

and simpler option use query parameter, think you're not okay it.

or can use sessionstorage:

sessionstorage.setitem("key", data); window.open("page_url","_blank"); 

on page use:

$(document).ready(function(){             var data = sessionstorage.getitem("key");     console.dir(data); }); 

note: the sessionstorage object equal localstorage object, except stores data 1 session. data deleted when user closes specific browser tab.
