When I'm in IE 6,7, use $('#someinput').attr('size', '20px'), IE will show error. I dig in jQuery 1.8.2, and find the code like this:

// Use this for any attribute in IE6/7

// This fixes almost every IE6/7 issue

nodeHook = jQuery.valHooks.button = {

get: function( elem, name ) {

//...

},

set: function( elem, value, name ) {

var ret = elem.getAttributeNode( name );

if ( !ret ) {

ret = document.createAttribute( name );

elem.setAttributeNode( ret );

}

return ( ret.value = value + "" );

}

};

So, 'return (ret.value = value + "" )' should become 'return (ret.value = parseInt(value, 10) + "") '

Sorry for my bad English ...
