Convert URL to json

Question

I can\'t seem to find an answer to this question.. How can I convert a URL parameters string to JSON in javascript? I mean to ask if there is an in-built function like this

Answer 1

I used satpal's answer to provide a nice Razor to JSON pipeline that works with Html.BeginForm, @Html.TextBoxFor etc.

The updated getUrlVars function looks like this:

function getUrlVars(url) {
    var hash;
    var myJson = {};
    var hashes = url.slice(url.indexOf('?') + 1).split('&');
    for (var i = 0; i < hashes.length; i++) {
        hash = hashes[i].split('=');
        var value = decodeURIComponent(hash[1]);
        value = value.replace("[\"", "");
        value = value.replace("\"]", "");
        value = value.replace(/\^.*/, "");
        myJson[hash[0]] = value;
    }
    return myJson;
}

The extra replace calls are for characters I get in my text boxes, probably via the dropdown magicSuggest lookups. The decodeURIComponent call cleans it up from %'s first.

I call it in a block like this:

    var serialized = $("#saveForm").serialize();
    var params = getUrlVars(serialized);

The Razor syntax I have looks like this:

@using (Html.BeginForm("SaveNewAddress", "Internal", FormMethod.Post, new { @Id = "saveForm" }))
{
    @Html.ValidationSummary()

    


        

            

                Is this a Liliputian Address?
            
            


                

                    
                        @Html.RadioButton("IsLiliputian", "Yes", true, new { @id = "IsLiliputianYes", @style = "width:30px" })
                    
                    Yes
                
                ...etc


This provides a nice way to get a bunch of data created in and via ASP.Net MVC controls in a js object that I can throw at a webservice via ajax.
