So i was working on an awesome project when i wanted to extract GET parameters from the URL string. Like in php $_GET['param'], i need to use javascript since the front end is building on an REST API [that is no direct interaction between front end and back end]. You probably should ave seen this feature used in google search and may others, but the problem is JavaScript donot provide such function to access the parameters like PHP. After searching for ages i found dozen or more codes that were good, bad and unusable. But most of the code weren't much portable or user friendly. So i decided to make my own JS class for it JsPara Download from github JsPara Homepage Features * Extract parameter=value pairs ex: index.html?search=test * Extract null valued parameters ex: index.html?c&d * Extract parameters followed by hash (#) (used in AJAX based sites) ex: index.html#search=test Logic JsPara simply use regular expression to find parameter=value pairs and then parameters with null value pairs. The Code Usage Using JsPara is so damn easy. You just have to attach the script (which is only 2kb) and initiate a new JsPara object For the sake of the tutorial, assume that the URL used here is http://example.com/index.html?search=keyword¬hing&page=1#p=new 1) Initiate a JsPara object with window.location Code: jp = new JsPara(window.location); //ex: http://example.com/index.html?search=keyword¬hing&page=1#p=new 2) To get all the extracted parameters [gives an array] Code: var paras = jp.params; //output: search, page, p, nothing 3) To get value corresponding to a parameter Code: var search = jp.param['search'] //output: keyword NOTE: Gives null if no value for the parameter 4) Get some other info about the URL Code: var hostname = jp.hostname; // example.com var protocol = jp.protocol; // http var path = jp.path; // example.com/index.html Limitations 1) Some characters are not valid in the URL [since the regex breaks if those characters are present] Valid parameter,value names & and # are not allowed [you dont say ] Code: test test123 test_me test me test.me "search" [1,"abc",'def'] so that's basically it, but this is HIGLY BETA so please please report me bugs and feature requests Cyah
