#url parameters

Need to access URL GET parameters with JavaScript? If yes, this is the tutorial for you. We cover how to retrieve the values of any URL parameter, aka URL variable, with only a few lines of code.

Hello folks, sometimes we need to get the URL parameters from the GET method, so I decided to create a small plugin for jQuery and get it.

/** * $.URL() - URL parameters via GET method * * It is a simple jQuery plugin to get * the parameters setted via GET method * * $.URL() to initialize it * $.URL.param('name') to get a specific value of the parameters * * @author Miguel Gocobachi <[email protected]> */ if (window.jQuery) { $(function($) { $.URL = function() { var params = window.location.href.slice( window.location.href.indexOf('?') + 1 ).split('&'); if (params.length > 0) { $.URL.parameters = {}; $.each(params, function(key, param) { param = param.split('='); $.URL.parameters[param[0]] = param[1]; }); } }; $.URL.param = function(name) { if (('undefined' === typeof name) || 'undefined' === typeof $.URL.parameters[name]) { return null; } return $.URL.parameters[name]; }; $.URL.parameters = null; }(jQuery)); }

URL parameters play a major role for search engine optimizers to filter out the results in many cases to get the desired output. I have a list of parameters which can be appended to existing URL in the address bar after searching for a keyword in Google. These are some of the important URL parameters which can be appended to the existing URL in the address bar.

1. Get the indexed results for only certain period of time: Assume that you want to filter out the results on a SERP to get the recently indexed results by the search engines for some reason. Google only allows you to view first thousand results (Since every page consists of 10 results at max you can access 100th page of a SERP for the keyword searched) for a keyword searched and not more than that.

To get the results from the past one month from Google for a keyword searched, you can append &as_qdr=m to the URL after searching for a keyword normally, similarly m2 for two months, m3 for three months etc. Also &as_qdr=w for one week, &as_qdr=w2 for two weeks, &as_qdr=d for results from past 24hrs, &as_qdr=d2 from the past two days and so on, &as_qdr=y to get the results from the past one year, &as_qdr=y2 for the results from the past two years and so on.

2. Switch of the Personalised Results: What If you are getting the same websites which you have already visited in the first page of the SERPs for a keyword again and again. It doesn't always mean that the website is very authoritative in the niche and ranks well for almost all the keywords in the niche. Search engines think that its better to give you that result at the top of the SERPs to improve the CTR since you have visited the website often by clicking on it in the search results. Search engines call this as personalisation. So search engines also take the data browser history from your browser and your search logs if you are signed in. Its always better to clear the cache and browser history before searching for a keyword which you have already searched on your browser to get what everyone gets as results for that keyword. or else append &pws=0 parameter to the URL after searching for a keyword on Google.

NodeJS opens up async database calls, with the use of mongoose you can model your scheme and validate the URL parameters on to the scheme, and insert your document object into your mongodb. 

var mongoose = require('mongoose');

var url = require('url');

var http = require('http');

mongoose.connect('mongodb://localhost/[yourdatabase');

var Schema = mongoose.Schema, ObjectId = Schema.ObjectId;

var CustomerRecord = new Schema({ firstname: String,lastname: String  ,email: String})

var newa = mongoose.model('customer',CustomerRecord);

function newaccount(response,request){   

customer = new newa;   

var url_parts = url.parse(request, true);   

var query = url_parts.query;       

query.prototype = customer;      

//reflect our validation    

customer.firstname = query.firstname; 

  customer.lastname = query.lastname;   

customer.email = query.email;          

  customer.save(function(err){}); 

//respond back your insertion     

response.writeHead(200, {"Content-Type": "text/html"});     response.write(JSON.stringify(query));  response.end('\n'); }
