Is there a way to turn off spell check in a textarea?

I used this question to get an answer to your question: Force spell check on a textarea in WebKit

HTML:

<textarea id="editor" spellcheck="true"></textarea>

Javascript:

$('#editor').focusin(function(){
    $(this).attr('spellcheck', true);
});

$('#editor').focusout(function() {
    $(this).attr('spellcheck', false);
    forceSpellcheck($(this));
});

    var canCheck = true;
    function forceSpellcheck($textarea) {
  if (canCheck) {
    canCheck = false;

    $textarea.focus();
    $textarea.attr('spellcheck', false);
    var characterCount = $textarea.val().length;

    var selection = window.getSelection();
    for (var i = 0; i < characterCount; i++ ) {
      selection.modify("move", "backward", "character");
    }

    // Remove focus from the element, since the word under
    // the cursor won't have a misspelling marker.
    $textarea.blur();
  } else {
    canCheck = true;
  }
}​

got it figured out

function bindEditorFocus() {
    var $editor = $('#editor');
    $editor.focusin(function(){
        $(this).attr('spellcheck', true);
        toggleSpellingcheck(); // loop through all words to add marker
    }); 
    
    $editorblur(function(){
        $editor.attr('spellcheck', false);
        $editor.unbind();    // I need to unbind all function to avoid a loop 
        toogleSpellingcheck(); // loop through all words to remove marker
        $editor.blur();     //get out of text area
        bindEditorFocus();  // rebind all functions 
    });
}


function toogleSpellingcheck(){ 
    //this will loop through all words
    var $editor = $('#editor'); 
    var text = $editor.val();       
    for (var i = 0; i < text.length; i++) {
        $editor.caret({start:i,end:i});
    }
}

the toogleSpellingcheck method loop through all words, it can be optimized to loop through words instead of characters, but this would need the jquery caret plugin

it's a bit messy, but works, anyone got suggestions on improvements please let me know
