Auto highlight new code

[Emil Ratazhkowski]

I'm trying to make this plugin to highlight code while user typing the code. Write some code

function update(){
 hljs.highlightBlock(document.getElementById('inp'));
}

$('pre').on('input', function(){
 clearTimeout(hid);
 hid = setTimeout(update, 1000);
})

The main issue is that after each call of highlightBlock
cursor jumps to the beginnig of the code. Maybe there is some solution for that?
