Widget rates

24.10.2011 15:17:09 Often that will spam site to give us something to shove and the client, web studio put on such a site currency exchange rates, weather forecast and other filth. However, I also put it on your site this stuff, but not because I particularly enjoy it, but because I developed a custom widget exchange rates, which is designed to facilitate web-studios vpihivaniyu stupidity of their customers' sites, so much so that this nonsense can be was converted into site design. Link to the informer can see on the right side of my site, as a true and he sticker.
In this article I will discuss how this technology works.
It was much easier than people usually come up with. Typically, this type of widget do for each site separately, the crown is parsed by rss from the site of the selected bank or if there is no rss, then directly to the page itself where there is relevant information. But judge for yourself how many resources hosting prosiraetsya if almost every web studio website regularly parses the bank site, well there is not even in this case, which happened just have to fix dozens of parsers and really not very convenient. In the studio saw it was done through a common database on the server, but sorry it's too bad a decision ...
So I thought maybe something new, but who knows the entire Internet did not check for unique ideas. So everything was easy.
On a separate server is a parser that generates the javascript file with multiple functions and sews up the array of the file specific values obtained with rss bank.
Then the script can be called from anywhere even with localhost. It works, and replaces the element at the right value from the file.
So for Kazakhstan web studios already have a widget and you do not have to do it can follow the link on the right side of the page, and not for Kazakh studios will be useful to the idea described above, so you can make out visible code and understand its meaning.
Incidentally I have also been written and other customizable ticker, weather forecast, that's just my mate who owns the server, nor how it gets to the installation of the informer
