get data from querystring in javascript

Question

im very new to getting data from one page to another and i have used querystring to pass data. and looks like this:

?redesigndata={"jsondata": "{\"images\":[ {\"src\":\"images/bgset.jpg\"},{\"src\":\"images/ar019.png\"}]}","product_hardware": "silver","product_thread": "white","product_lining": "Blue","product_lining_loc": "images/lining/blue_80x32.jpg"}

How do i remove all the \ from it and then put it into an object or any thing like this with Javascript or jQuery:

redesigndata = {
    "jsondata": "{"images":[ {"src":"images/bgset.jpg"},{"src":"images/ar019.png"}]}",
    "product_hardware": "silver",
    "product_thread": "white",
    "product_lining": "Blue",
    "product_lining_loc": "images/lining/blue_80x32.jpg"
}

$.param

location.search will get you the querystring (starting with the ?). Strip off the ?, split it at =, then JSON.parse it.

var jsonStr = location.search.substring(1).split('=');
var obj = JSON.parse(unescape(jsonStr[1]));

Then you can parse jsondata.

var jsondata = JSON.parse(obj.jsondata);

Why would you remove those backslashes? Without them you the JSON wouldn't be valid anymore. Right now you have nested JSON so you can parse it like this (with str being the redesigndata value):

var redesigndata = JSON.parse(JSON.parse(str).jsondata);
