jQuery Forum

First, my English is poor
We can get the corresponding URL via jquery params method，like that：

1. var params= '{ "a": [ 0, [ 1, 2 ], [ 3, [ 4, 5 ], [ 6 ] ], { "b": [ 7, [ 8, 9 ], [ { "c": 10, "d": 11 } ], [ [ 12 ] ], [ [ [ 13 ] ] ], { "e": { "f": { "g": [ 14, [ 15 ] ] } } }, 16 ] }, 17 ] }'
2. $.params(params)
3. /*get params 
4. a[]=0&a[1][]=1&a[1][]=2&a[2][]=3&a[2][1][]=4&a[2][1][]=5&a[2][2][]=6&a[3][b][]=7&a[3][b][1][]=8&a[3][b][1][]=9&a[3][b][2][0][c]=10&a[3][b][2][0][d]=11&a[3][b][3][0][]=12&a[3][b][4][0][0][]=13&a[3][b][5][e][f][g][]=14&a[3][b][5][e][f][g][1][]=15&a[3][b][]=16&a[]=17
5. */

But sometimes we need to turn，For example, from one page to another page , and we need to bring a lot of arguments，No back-end support. So deserialization need to do our own.

I have developed a unserialise function，and i want to add to jquery.

3. 'use strict'
4. 
   
5. let uri = 'a1=123&b1[a2]=123&c1=dsss&d1[0][a3]=123&d1[0][b3][a4]=123&d1[1][a3]=123&d1[2][]=1&d1[2][]=2&d1[2][]=1&d1[2][]=3&d1[2][]=4'
6. 
   
7. unserialize(uri);
8.

11.     let parts = uri.split('&');
