How to show previous window using javascript. i have two html page like test1.html and test2.html

test1.html

 <button id="newWindow">New Window</button>

test2.html

 <button id="prevPage">ok</button>

If i click newWindow button from test1.html it will go to test2.html in new tab window.

If i clcik prevPage button from test2.html page it will close current window tab and should go to the test1.html tab window.

     $(document).on('click', '#newWindow', function () { 
     window.open("test2.html"); 
     });

     $(document).on('click', '#prevPage', function () {

     /*close pressent window(test2.html)*/
     window.close();

     /*open the test1.html tab window*/

     window.opener('test1.html','parent').focus();

     });

Answer 1

I'm pretty sure you need to have the first window still open in order to open a new one, otherwise the js function process is lost before that happens. So you should open your new window first, then close the original one. Like this:

$(document).on('click', '#newWindow', function () { 
    /*open test2.html*/
    window.open('test2.html').focus();

    /*close test1.html*/
    window.close();
});

$(document).on('click', '#prevPage', function () {
    /*open test1.html*/
    window.open('test1.html').focus();

    /*close test2.html*/
    window.close();
});

为什么不依赖历史对象和简单的写入

window.history.back();
