Use jQuery get rss (with JavaScript) to get a blogs (or websites) display rss feed on your web page. Use Google Ajax Feed API to retrieve the feed items and returns them as a list of feed items to be displayed. The feed can then be customized with your styles to suit your look – for example it could be used as a jQuery news aggregator.

The jQuery RSS Plugin Code

The jQuery RSS Plugin mainly uses JavaScript to call google.load(feed) to get the rss feed items.
var gfeedfetcher_loading_image="/images/page-images/loader.gif" //Full URL to "loading" image. No need to config after this line!!

google.load("feeds", "1") //Load Google Ajax Feed API (version 1)

function gfeedfetcher(divid, divClass, linktarget){
	this.linktarget=linktarget || "" //link target of RSS entries
	this.feedlabels=[] //array holding lables for each RSS feed
	this.feeds=[] //array holding combined RSS feeds' entries from Feed API (result.feed.entries)
	this.feedsfetched=0 //number of feeds fetched
	this.showoptions="" //Optional components of RSS entry to show (none by default)
	this.sortstring="date" //sort by "date" by default
') //output div to contain RSS entries this.feedcontainer=document.getElementById(divid) this.itemcontainer="
  • " //default element wrapping around each RSS entry item } gfeedfetcher.prototype.addFeed=function(label, url){ this.feedlabels[this.feedlabels.length]=label this.feedurls[this.feedurls.length]=url } gfeedfetcher.prototype.filterfeed=function(feedlimit, sortstr){ this.feedlimit=feedlimit if (typeof sortstr!="undefined") this.sortstring=sortstr } gfeedfetcher.prototype.displayoptions=function(parts){ this.showoptions=parts //set RSS entry options to show ("date, datetime, time, snippet, label, description") } gfeedfetcher.prototype.setentrycontainer=function(containerstr){ //set element that should wrap around each RSS entry item this.itemcontainer="< "+containerstr.toLowerCase()+">" } gfeedfetcher.prototype.init=function(){ this.feedsfetched=0 //reset number of feeds fetched to 0 (in case init() is called more than once) this.feeds=[] //reset feeds[] array to empty (in case init() is called more than once) this.feedcontainer.innerHTML='
