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=document.links;for(i=0;i<dl.length;i ++)dl[i].title==""?dl[i].title=dl[i].href:dl[i].title.substring(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=document.forms;for(j=0;j<df.length;j++)d f[j].title=df[j].action;void(null)

Broken up into readable lines, that's

javascript:dl=document.links;for(i=0;i<dl.length;i ++)dl[i].title==""?
dl[i].title=dl[i].href:dl[i].title.substring(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=document.forms;for(j=0;j<df.length;
j++)df[j].title=df[j].action;void(null)

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.forms;for(i=0;i<d.length;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! :)
