I am trying to retrieve data from another page by using sessionstorage.

My first page home.html

function go_to_faq(qnum){

window.open('FAQ.html', '_blank');

sessionStorage.setItem('key2', qnum);

}

<a style="cursor: pointer;" onclick="go_to_faq('1')" target="_blank"> Open First Question </a>
<a style="cursor: pointer;" onclick="go_to_faq('2')" target="_blank"> Open Last Question</a>

Second page FAQ.html

var qpara2 = sessionStorage.getItem('key2');

alert(qpara2);

First issue:

At first click on (Open First Question), it give me null. Second click gives me the right value(1).

If I click the second link (Open Last Question), it gives me the last old value (1). When I click it again it will update it and give me (2). So it does not work properly from the first click.

Second issue:

It does not work in IE.
