bookmarklet code

stop annoying advertisements

Hello everybody,

Here is some (poor) bookmarklet script:

javascript:a=document.getElementsByTagName('iframe');
b=document.getElementsByTagName('EMBED');
c=document.getElementsByTagName('img');
for(n=0;n<a.length;n++){i=a[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden'};
for(n=0;n<b.length;n++){i=b[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden'};
for(n=0;n<c.length;n++){i=c[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden';}void 0;

Currently the above bookmarklet hides iframes, flash objects, and all images - leaving you with a nice clean Zenlike browser with undiluted content. (based off a more elegant script from O'Reilly's JavaScript The Definitive Guide (a great book)).

Instead of removing all of the images, I would just like to disable the API's that control Flash execution and .gif animation - if possible - or just hide Objects and .gif's (which also stumps me).

My question is - how can one locate .gif images on a page via DOM/JSP or is that even possible. It's gotta be.

solution: assign all image elements to a string, use a regular expression to bool for *.gif matches and hide the 0's

javascript:a=document.getElementsByTagName('iframe');
b=document.getElementsByTagName('EMBED');
c=document.getElementsByTagName('img');
for(n=0;n<a.length;n++){i=a[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden'};
for(n=0;n<b.length;n++){i=b[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden'};
for(n=0;n<c.length;n++){i=c[n];
if(i.width!=0&&i.height!=0)i.style.visibility='hidden';}void 0;

now, when this bookmarklet is triggered, all iframes, embedded objects, and gifs are hidden...dramatically quieting down the page for easier user content digestion.

sry wrong code, here is the correction and with flushed out code & complete snippet on bottom:

javascript:a=document.getElementsByTagName('iframe'); // get all iframes
b=document.getElementsByTagName('EMBED'); // get all flash
c=document.getElementsByTagName('img'); // get all images
for(n=0;n<a.length;n++){ // loop thru all iframes and hide 'em
i=a[n];
i.style.visibility='hidden';
}
for(n=0;n<b.length;n++){ // loop thru all embeds and hide
i=b[n];
i.style.visibility='hidden';
};
for(n=0;n<c.length;n++){ // loop thru all images
i=c[n];
q=i.src;
x = /.gif/.test(q); // find all gifs
if(x==true)i.style.visibility='hidden'; // if a gif then hide
}
void 0;

here is the code in a nice single chunk, to paste into a bookmark (in order to generate a bookmarklet)

javascript:a=document.getElementsByTagName('iframe');b=document.getElementsByTagName('embed');c=document.getElementsByTagName('img');for(n=0;n<a.length;n++){i=a[n];i.style.visibility='hidden';}for(n=0;n<b.length;n++){i=b[n];i.style.visibility='hidden';};for(n=0;n<c.length;n++){i=c[n];q=i.src;x =/gif/.test(q);if(x==true)i.style.visibility='hidden';}void 0;
