How to access serialized form data and process it?

Question

I have serialized data on html page and want to process it.

My data format is like :

    "lusername=unm1&lpassword=p1&lpassword=p2""lusername=unm2&lpassword=unm2p1&lpassword=unmp2""wusername=unmw1&wpassword=pw1&wpassword=pw2
w2""wusername=unmw2&wpassword=pw1""snmpsettings=pqr""subnet=1.1.1.1"

I want to process above data to sort out final data string as :

lusername=unm1;lpassword=p1,p2;
lusername = unmw2; lpassword = pw1,pw2;
snmpsettings = pqr

How do deserilize my data to get above output?

But when I access html elements data by using serialize(), I am getting string gien in question. — user3322141, Jun 02 '14 at 08:23
@Superdrac: "The word `data` is the traditional *plural form* of the now-archaic datum". Please don't say "datas"... even as a joke :) — iCollect.it Ltd, Jun 02 '14 at 08:31
Thank you @TrueBlueAussie ! I also saw that you edited all my posts :D ! Sorry (i'm french). — Superdrac, Jun 02 '14 at 08:38
How did you create the string to begin with? If you used serialize() would serializeArray have been better for you? — PeterKA, Jun 02 '14 at 19:26

You can do a split on a specific character see: How do I split a string, breaking at a particular character?

You probably will need to do multiple splits to give you the proper array structure and values.

You're probably looking for something like this:

var data = '"lusername=unm1&lpassword=p1&lpassword=p2""lusername=unm2&lpassword=unm2p1&lpassword=unmp2""wusername=unmw1&wpassword=pw1&wpassword=pw2w2""wusername=unmw2&wpassword=pw1""snmpsettings=pqr""subnet=1.1.1.1"',
    objs = data.split(/"{1,2}/);
var newArr = [];
$.each(objs,function( i, item ) {
    if( item !== "" ) {
        var parts = item.split( '&' ),
            x = {};
        $.each( parts, function( index, value ) {
            var key = value.split( '=' )[0],
                val = value.split( '=' )[1];
            x[ key ] = ((!!x[ key ]) ? x[ key ] + ',' : '') + val;
        });
        newArr.push( x );
    }
});
console.log( newArr );
