I am assuming you don't want the text to be blank or just a space? I usually run the text through a validator that I wrote that replaces all spaces and then checks to see if it is an empty string... for example,

var Validator = {
string : function( string )
{
if( typeof( string ) != 'string' || string == '' || string.replace( ' ', '' ) == '' )
return false;
else
return true;
}
}

The replace function is not built in, so if you don't have it, then you must include this above the function:

Object.extend = function(destination, source) {
for (property in source) {
destination[property] = source[property];
}
return destination;
}

Object.extend(String.prototype, {
replace : function( from, to )
{
var s = this;
var arr = s.split(from);
return arr.join(to);
}
}

Then you can just say:

if( Validator.string( this.abc.getText() ) )
{ body }
else
{
body }
