问题
Given: I load a queue of messages at page load.
With jGrowl, how can I display each message, one message at a time, in a drip-like fashion?
回答1:
I needed to do this for a project, a few months ago. If you use the pooling feature, available in the latest jGrowl (1.2.0 as of this writing), you can simply write:
$.jGrowl.defaults.pool = 1;
That way, you can load all of them at the same time, jGrowl will take care of only showing one at a time. When a message closes, jGrowl will automatically display the next one.
I hope this is what you wanted.
回答2:
$.jGrowl.defaults.pool == 0;
if ( $(this.element).find('div.jGrowl-notification:parent').size() < 0 ) {
Currently working on site notifications, I couldn't find a way to show one at a time until I found this page. Thanks Bruno! You saved me. :)

Since you specify the time interval that a message is displayed for (at maximum), you could simply use a JS setTimeout to loop through an array at the same interval, creating a new message.
Alternatively, jGrowl can take a function(e,m,o) as its close parameter, and it will use it as a callback whenever a message is closed. In this function, create a new message from your queue and you should be set. See documentation here.
