How to hide flash message after few seconds?

问题

In my application user can post challenge for other user. So after successful posting a challenge I am displaying one flash message for the same. But now I want to hide this message after some few seconds. So I wrote following code :

$(document).ready(function(){
    setTimeout(function() {
        $("#successMessage").hide('blind', {}, 500)
    }, 5000);
});

<div id="successMessage" style="text-align:center; width:100%">
    <FONT color="green">
        <%if flash[:alert]=="Your challenge is posted successfully."%> 
            <h4><%= flash[:alert] if flash[:alert].present? %>
        <%end%>
    </font>
</div>

But this code is not hiding the div "successMessage".

回答1:

You can try :

setTimeout(function() {
    $('#successMessage').fadeOut('fast');
}, 30000); // <-- time in milliseconds

If you used this then your div will be hide after 30 sec.I also tried this one and it worked for me.

You can use the delay jQuery API to achieve this.

$(document).ready(function(){
    $("#successMessage").delay(5000).slideUp(300);
});

Someone posted a similar question to stackoverflow with this solution:

<script type="text/javascript">window.setTimeout("document.getElementById('successMessage').style.display='none';", 2000); </script>

<div id="successMessage"> bla bla bla
</div>

I'd share the link but I can't find it anymore. Thanks for the help, though, mystery human!

Some times it's not enough to only setting display of box to none it's better to completely remove it. as follows:

setTimeout(function() {
    $('.alert-box').remove();
}, 30000);
