# last.fm bookmarklets
|
||
|
|
|
||
|
|
last.fm doesn't let you see how many scrobbled you've made in one day particularly easily.
|
||
|
|
Here is a bookmarklet to solve that.
|
||
|
|
|
||
|
|
<label for="days"> Number of days to view: </label>
|
||
|
|
<input type="number" value="1" id="days" placeholder="Days"/><br><br>
|
||
|
|
<label for="offset"> Offset (e.g. 0 to include today, 7 to look at last week): </label>
|
||
|
|
<input type="number" value="0" id="offset" placeholder="Offset (Days)" /><br><br>
|
||
|
|
<label for="username"> last.fm username </label>
|
||
|
|
<input type="text" value="" id="username" placeholder="Username" /><br><br>
|
||
|
|
<input type="button" id="button" value="Generate bookmarklet"><br>
|
||
|
|
|
||
|
|
<p><a style="display: none" href="" id="scriptLink">Bookmark this link</a></p>
|
||
|
|
|
||
|
|
When you press generate bookmarklet, the values `OFFSET`, `DAYS`, `USERNAME` will be
|
||
|
|
subsituted and put into the link above.
|
||
|
|
It's always best to inspect bookmarklets though.
|
||
|
|
Inspect the page to view the script used to generate the bookmarklet.

|
<textarea cols="109" rows="15" readonly id="scriptText">
|
||
|

javascript: (() => {
|
||
|
|
const MILLESECONDS_PER_DAY = 1000 * 24 * 60 * 60;
|

|

const USERNAME;
|

const currentDate = new Date();
|
||
|
|
const to = new Date(currentDate - (OFFSET * MILLESECONDS_PER_DAY));
|
||
|
|
const from = new Date(to - ((DAYS-1) * MILLESECONDS_PER_DAY));
|
||
|
|
const toDate = to.getFullYear() + "-" + (to.getMonth()+1) + "-" + to.getDate();
|

|
|
const fromDate = from.getFullYear() + "-" + (from.getMonth()+1) + "-" + from.getDate();
