I have currently been making a word search maker, but I have occurred a problem. The problem is that I'me using a table with contenteditable, but how do I set a max string length. I already tried
maxlength="1"
Can anyone please help!

Please, if there are any ways, please try avoid jquery!
You can either change those to inputs, or use the following JavaScript
var pre = onload, doc, T, oneCharOnly; // change pre to another var if using technique on different page
onload = function(){
if(pre)pre();
doc = document;
T = function(n, e){
var w = e || doc;
return w.getElementsByTagName(n);
}
oneCharOnly = function(){
var tds = T('td');
for(var i=0,l=tds.length; i<l; i++){
tds[i].onkeyup = function(){
if(!this.innerHTML.match(/^.$/)){
this.contentEditable = false;
}
}
}
}
oneCharOnly(); // okay to use on other pages due to scope
