QueryBuilder allows only a simple set of criteria combined by either AND or OR. Expression Builder extends this to allow any boolean expression, no matter how complex.

Creates a textarea with the specified name and id and registers a validation function for this textarea with the given FormManager instance. Uses the QueryBuilder instance to provide a convenient way to insert a clause into the textarea.

Code Sample

<script src="http://yui.yahooapis.com/3.5.1/build/yui/yui-min.js"></script>

YUI({
    //Last Gallery Build of this module
    gallery: 'gallery-2012.05.16-20-37'
}).use('gallery-exprbuilder', function(Y) {
 
	var form = new Y.FormManager('expr_form');
	form.prepareForm();
 
	var expr = new Y.ExpressionBuilder({
		fieldName:    'sql_expr',
		fieldId:      'sql-expr',
		formMgr:      form,
		queryBuilder: new Y.QueryBuilder(...)
	});
	expr.render(...);
 
});
