20 second delay for page loading

Is there any frontend component (Dojo or javascript) which holds the page to wait for loading for around 20 seconds. I am right now using Dojo with my jsp. help is appreciated

nothing officially waits to load the page, but the front end does have to load the html before it can display, having large scripts can slow the loading of a page.

Firebug for firefox, or the developer tools for IE8 and Chrome can show you what is loading when to let you see how long things take.  

Also ySlow is a plugin for Firebug in Firefox that analyzes your page to let you know why it's slow.  I like this one better than some of the other tools out there because it works behind a firewall.

You could use jquery.


var $htmlChildren = $('html').children();
$htmlChildren .remove();
setTimeout(function() { $('html').append }, 20000);

Open in new window

Probably should be the below.. since the above is not complete


$(document).ready(function(){
    var $htmlChildren = $('html').children().remove();
    setTimeout(function() { $('html').append($htmlChildren); }, 20000);
});

Open in new window

@KiasChaos thanks for the solution. but is there any other way to get this done using plain java script .. or any other ajax frameworks such as Dojo or DWR

I misunderstood, are you trying to prevent the page for loading for a certain amount of time?  Do you mind if I ask why?

Hi there,

This seems to do it.


dojo.ready(function() {
    dojo.require("dojo.NodeList-traverse")
    var html = dojo.query('html').children();
    html.style({display:'none'});
    setTimeout(function() { html.style({display:''}); }, 5000);
});
