Do the page preview, the data is not stored in the database, but to open a page to preview, ask the aunt, the original is to do so.

1. Parent page

<input type="text" id="name" value="zhangsan"/>
<a href="a.html" target="_blank"> preview </a>

2. The child page, a.html, gets the value of the text box in the parent page

$(function(){

console.info(window.opener.document.getElementById("name").value);
});

What comes out of the console is the value of the parent page’s textbox

Don’t hurry say have no choice, perhaps, next intersection will meet hope.
