Redirect and then alert

Question

I'm processing something and when the function is successful I would like to redirect to another page and there show the alert "Function successful".

I'm using CodeIgniter, Javascript and Bootstrap

Any ideas will be appreciated

How are you processing this? Was it done through a form submission or via AJAX? — Nick Mitchinson, Jan 29 '13 at 22:47
I'm doing this in a separate view and in the success function of an ajax call I redirect to, lets say, an index in which I would like to fire the alert — jonathanwiesel, Jan 29 '13 at 22:49

Once page X has redirected to page Y, page X is no longer open, so can no longer issue alerts. Your options include:

don't redirect. (Instead, you may be able to put page Y in an iframe; or, simply provide a link to it and let the user decide whether to click.)
don't alert.
alert before redirecting. (This is basically the same thing. The user can't actually interact with page Y until they've closed the alert, anyway, so it doesn't really matter whether the alert comes before or the redirect or after it.)
have page Y give the alert. For example, page X can redirect to http://example.com/path/to/Y/?alert=Function+successful, and you can design page Y to detect the query string and issue the alert.

Using codeigniters flashdata sessions are also an option : http://ellislab.com/codeigniter/user-guide/libraries/sessions.html — Jeemusu, Jan 30 '13 at 02:46

When the functions is successful, redirect and use the body onload event of the new page. Using a querystring extraction based on another SO answer:

if (success)
{
window.location("anotherpage.html?myparm=alertMe");
}

...

anotherpage.html

<body onload="bodyLoad();">
...
</body>

<script type="text/javascript">
function bodyLoad()
{
  parmValue = getParameterByName("myparm");
  if(parmValue == 'alertMe')
  {
    alert('Function successful');
  }
}

//http://stackoverflow.com/questions/901115/how-can-i-get-query-string-values
function getParameterByName(name) {
    var match = RegExp('[?&]' + name + '=([^&]*)').exec(window.location.search);
    return match && decodeURIComponent(match[1].replace(/\+/g, ' '));
}
</script>

this doesn't work for me because the page I will load doesn't always receive that notification – jonathanwiesel Jan 29 '13 at 22:51
@EnforcerW You could add a querystring variable and check that before the alert – amelvin Jan 29 '13 at 22:52
