javascript - Navigate to specific anochor tag via up and down arrow press -



javascript - Navigate to specific anochor tag via up and down arrow press -

i using anchor tags , have implemented smooth scrolling on 5 links. works perfectly. however, add together ability utilize arrow keys navigate through these same anchor tags.

i can fumble through javascript , jquery, i'm pretty confused when comes stuff.

<ul> <li class="scrolldot"><span><a href="#one">1</a></span></li> <li class="scrolldot"><span><a href="#two">2</a></span></li> <li class="scrolldot"><span><a href="#three">3</a></span></li> <li class="scrolldot"><span><a href="#four">4</a></span></li> <li class="scrolldot"><span><a href="#five">5</a></span></li> <li class="scrolldot"><span><a href="#six">6</a></span></li> </ul>

so basically, want user nail downwards arrow , them taken next section, depending on over page. if on section 2, take them three. if nail again, taken 2 , forth. create sense?

checkout mousetrap. it's nifty little library makes binding keys pretty easy. there few examples on site well.

perhaps suffice:

mousetrap.bind('up', function() { your_up_function(); }); mousetrap.bind('down', function() { your_down_function(); });

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
