How to post data from a geoJSON data to a form in the next page?



I am trying to link geoJSON data with a custom form. The GeoJSON data is visible on a map and whn a polygon is clicked it goes to a new page which allows user to add/update data in it. But it must take the number mentioned on the polygon to the form in the next page. Here is the code:

The part of the code when the user clicks on the polygon and the router is placed:

layer.on('click', function(e) {
	var string =
	Router.go('/Details/', string);			

The router code:{
//Home Route

this.route(‘home’, {
path: ‘/’,
template: ‘home’

this.route(‘PlotDetails’, {
template: ‘PlotDetails’


What should I add in “this.route” in order to send the string data mentioned in the above code snippet and paste it in:

<template name="PlotDetails">    
    <form action="" method="">
    	<div class="form-group">
    		<label for="">SNo/TP No</label> <input type="text" class="form-control" id="sntp" />

Kindly help.
Thank you in advance.
