Java in Firefox Address bar

Copy linkTweet thisAlerts:
Aug 18.2007

A brief introduction. I’m completely new to javascript but am hoping it will help solve this issue:

I’m trying to be able to click a bookmark and find detailed weather for the current day with one click. I know that you can use java in the address bar to go to a particular link.

e.g. (with no breaks)
javascript:location.href=’http://www.xxx.xxx/‘

The particular link I need, requires the current day of the year number as part of the link. Day of year can be calculated with this formula:

Date.prototype.getDOY = function() {
var onejan = new Date(this.getFullYear(),0,1);
return Math.ceil((this – onejan) / 86400000)-1;
}

How can I use java to calculate the current day of the year and insert it into the url? All on one line so it can be saved as a bookmark on Firefox.

Thanks for any help on this.

@Orc_ScorcherAug 18.2007 — To create a bookmarklet, write your script like you usually would, nicely formatted to improve readability. Just one caveat: for bookmarklets you [b]must[/b] end your statements with a semicolon, in normal scripts these are usually optional.

The script to go to your URL with the day of the year appended would look like this:Date.prototype.getDOY = function() {
var onejan = new Date(this.getFullYear(),0,1);
return Math.ceil((this - onejan) / 86400000)-1;
}

var today = new Date;

location.href = "http://www.example.com/?day=" + today.getDOY();

Now, copy that code and paste it into the [url=http://subsimple.com/bookmarklets/jsbuilder.htm]this page[/url], prepend it with 'javascript:', press the 'Compress' button and you're done.

Success!
