Node.js Chat client with jQuery Mobile

Guido Krömer - 2214 days ago - Tags: , ,

Welcome to the last part of my node.js chat tutorial, the topic of this part is the jQuery Mobile based client. The decision choosing jQuery Mobile has the two reasons, the UI I created for "WebSockets chat with Node.js " was really ugly because I'm not a designer, so I decided taking something which looks well out of the box. The second reasons was that jQuery Mobile seems to be well tested on different browsers even if they are not WebKit based. If you have not read the server side tutorial you maybe should read it before.

Prevent impatient users to click a link several times

  • Fact 1: Users are very impatient.
  • Fact 2: Some pages have a really long request time.
  • Fact 3: Users try to improving the request time by clicking several times the same link.

This can be bypassed by disabling the links on a page when they got clicked.

$('.one_click_link').click(function() {
    $(this).click(function() {
        return false;

This solution has one disadvantage, if the user decides to click another link and reverts his decision the already clicked links are still disabled. This is the reason I used the class "one_click_link" which will be assigned to "problematic" links, instead of giving all links on a page this availability using $('a')...
