I want to prohibit the Back function of the browser. Therefore I write the following codes in html.
<body>
<script type="text/javascript">
<!--
history.forward()
//-->
</script>
</body>
but'The above "history.forward()" did not work suddenly when I coding html and some javascripts.
What's wrong? In addition, please teach the different method that had a similar function. Thanking you in advance.
Using the history object
window.history.go(positive integer)
will take you forward through history, so
window.history.go(1)
will take you forward one page.
Also, make sure you're referencing the window object.
window.history.forward()
should also work
My recommendation is to not restrict the user's browser. Web browsers have back buttons and that's the way it is. You should architect your application so that it works when the user uses the back button, such as by expiring the page and properly handling the refresh of a previous page. If disabling the back button is some attempt at security, realize that there are ways around it, especially if javascript is disabled.
If I ended up on your site and found that everytime I hit the back button the page would ignore it I would be very unhappy. You can't know that you are the first site in the browsing history.
In my opinion, having javascript functionality to control the user's history was a bad addition.
