I have a 3 pages from 1st page to second and second to third im sending some information.what i wanted to do is if im in the second page i want user to not to go back to 1st page again or in 3rd place users can go to 1st or 2nd page.
Is there is a way to disable back button on browser?or is there is a way to show an error when user press back button?
Any suggestions?
This is my old code for that inside my Master Page It's been a couple of years since I made this, your choice if you want to update it.
Protected Overrides Sub OnPreRender(ByVal e As System.EventArgs)
MyBase.OnPreRender(e)
Dim disAbleBackButton As String
disAbleBackButton = "<script language='javascript'>" & Environment.NewLine
disAbleBackButton &= "function noBack(){window.history.forward()}" & Environment.NewLine
disAbleBackButton &= "noBack();" & Environment.NewLine
disAbleBackButton &= "window.onload=noBack;" & Environment.NewLine
disAbleBackButton &= "window.onpageshow=function(evt){if(evt.persisted)noBack()}" & Environment.NewLine
disAbleBackButton &= "window.onunload=function(){void(0)}" & Environment.NewLine
disAbleBackButton &= "</script>"
Page.ClientScript.RegisterClientScriptBlock(Me.Page.GetType(), "backhistory", disAbleBackButton)
End Sub
Try below code for disable browser back button using javascript.
<script type="text/javascript" language="javascript">
function DisableBackButton() {
window.history.forward()
}
DisableBackButton();
window.onload = DisableBackButton;
window.onpageshow = function(evt) { if (evt.persisted) DisableBackButton() }
window.onunload = function() { void (0) }
</script>
Try below code to block back & forward buttons on the browser.
window.history.pushState(null, "", window.location.href);
window.history.back();
window.history.forward();
window.onpopstate = function() {
window.history.pushState(null, "", window.location.href);
};
