gAjax RSS Feeds Displayer - trigger jQuery function?

[kblm]

1) Script Title: gAjax RSS Feeds Displayer

2) Script URL (on DD): http://www.dynamicdrive.com/dynamicindex18/gajaxrssdisplayer.htm

3) Describe problem:

Is there anyway to have the gAjax RSS Feeds Displayer script....make a call to a jQuery function ONCE it's done loading feeds?

I am trying to put this into a jQuery scroller.....the scroller at times is firing before the RSS script is done outputting (I think).

For now, I'm delaying the jQuery scroller with a set time....but I'd like to have the scroller only fire when the RSS feed script is done.

Any clues on how to do that?

So do you think it's ok to just put my jQuery calls at the end of the:

gfeedfetcher.prototype._displayresult=function(feeds){

function?

Won't this not load the jQuery until all the feeds are written out?

I've just updated the official version of the script (http://www.dynamicdrive.com/dynamicindex18/gajaxrssdisplayer.htm) to incorporate the two features you asked for:

1) Ability to execute your own code when a RSS Displayer has loaded, via the callback function onfeedload()

2) Script now skips a RSS feed entirely if it's invalid, moving on to the next if there are more than one feed defined for a RSS Displayer.

Only the .js file of the script has been modified. To take advantage of 1), just use the syntax:


var newsfeed=new gfeedfetcher("example3", "example3class", "_new")
newsfeed.addFeed("BBC", "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml") //Specify "label" plus URL to RSS feed
newsfeed.addFeed("MSNBC", "http://www.msnbc.msn.com/id/3032091/device/rss/rss.xml") //Specify "label" plus URL to RSS feed
newsfeed.addFeed("Yahoo News", "http://rss.news.yahoo.com/rss/topstories") //Specify "label" plus URL to RSS feed
newsfeed.displayoptions("datetime snippet") //show the specified additional fields
newsfeed.setentrycontainer("p") //Display each entry as a paragraph
newsfeed.filterfeed(8, "date") //Show 8 entries, sort by date
newsfeed.onfeedload=function(){
alert('hi')
}
newsfeed.init() //Always call this last

Thank you so much! That is AWESOME!

Going to grab the new code and try it out now.

cssfeed.displayoptions("date") //show the specified additional fields
cssfeed.setentrycontainer("div") //Wrap each entry with a DIV tag
cssfeed.filterfeed(10, "date") //Show 10 entries, sort by date
cssfeed.entries_per_page(1)
cssfeed.onfeedload=function(){
alert('all done!')
}
cssfeed.init()

Couple of questions....

You have a different var:
var cssfeed=new gfeedpausescroller("example1", "example1class", 2000, "_new")

And a new option:
cssfeed.entries_per_page(1)

I'm guessing these aren't supposed to be in there? When I remove them and set it back to the original gfeedfetcher it works.

Hi Kevin:
Yep, "cssfeed" is just an example, you should replace it with the variable name you used to initialize the script. cssfeed.entries_per_page(1) shouldn't be there, I've removed it.

Yeah I got that part....I was asking about the gfeedpausescroller and the option: .entries_per_page(1)

I need to call gfeedfetcher for it to work.

Are those for a different script?

Ah yes I see why you're confused- I used a variant of the RSS Displayer script, the RSS Scroller, in the sample code I posted. The process is the same, but here is an example initialization code for RSS Displayer itself:


var newsfeed=new gfeedfetcher("example3", "example3class", "_new")
newsfeed.addFeed("BBC", "http://newsrss.bbc.co.uk/rss/newsonline_uk_edition/front_page/rss.xml") //Specify "label" plus URL to RSS feed
newsfeed.addFeed("MSNBC", "http://www.msnbc.msn.com/id/3032091/device/rss/rss.xml") //Specify "label" plus URL to RSS feed
newsfeed.addFeed("Yahoo News", "http://rss.news.yahoo.com/rss/topstories") //Specify "label" plus URL to RSS feed
newsfeed.displayoptions("datetime snippet") //show the specified additional fields
newsfeed.setentrycontainer("p") //Display each entry as a paragraph
newsfeed.filterfeed(8, "date") //Show 8 entries, sort by date
newsfeed.onfeedload=function(){
alert('hi')
}
newsfeed.init() //Always call this last

Thanks so much. Works perfectly!
