facebox 模态对话框

点空白处 不关闭对话框 必须点关闭按钮或Esc

1.Add one parameter in settings

$.extend($.facebox, {
settings: {
opacity : 0.5,
overlay : true,
modal : true, //New parameter
........

}

2. Modify the function showOverlay()
replace the line .click(function() { $(document).trigger
('close.facebox') })
with .click(function() {
if ($.facebox.settings.modal != true)
$(document).trigger('close.facebox')

})
