bookmarklet: tooltips on links

[Michael Hamm]

Here's a neat bookmarklet for putting tooltips on links. I got the idea
a long time ago somewhere and made it much better than it started out.

javascript:dl=d ocument.links;f or(i=0;i<dl.len gth;i++)dl[i].title==""?dl[i].title=dl[i].href:dl[i].title.substrin g(dl[i].title.length-dl[i].href.length,dl[i].title.length)! =dl[i].href?dl[i].title+=": "+dl[i].href:dl[i].title=dl[i].title;df=docum ent.forms;for(j =0;j<df.length; j++)df[j].title=df[j].action;void(nu ll)

Broken up into readable lines, that's

javascript:dl=d ocument.links;f or(i=0;i<dl.len gth;i++)dl[i].title==""?
dl[i].title=dl[i].href:dl[i].title.substrin g(dl[i].title.length-dl[i]
..href.length,d l[i].title.length)! =dl[i].href?dl[i].title+=": "+dl[i].
href:dl[i].title=dl[i].title;df=docum ent.forms;for(j =0;j<df.length;
j++)df[j].title=df[j].action;void(nu ll)

Cute, but I'm sure it can be done shorter :)

<URL: javascript:var D=document,d=D. links,h,i,c;for (i=0;i<d.length ;i++){c=d[i];t=c.title;h=c. href;c.title=t? t.indexOf(h)>=0 ?t:t+": "+h:h;}d=D.form s;for(i=0;i<d.l ength;i++){d[i].title=d[i].action;}D=void 0; >

Except for the "void 0;" at the end, it even passes JSLint.
(There seems to be no way to make JSlint accept "void").

Readable?!?
Shorter would be correct! :)
