jQuery Serialize
In jQuery 1.4 HTML5 input elements are serialized, as well.
We can display a query string representation of an object and a URI-decoded version of the same as follows:
a%5Bone%5D=1&a%5Btwo%5D=2&a%5Bthree%5D=3&b%5B%5D=1&b%5B%5D=2&b%5B%5D=3
a[one]=1&a[two]=2&a[three]=3&b[]=1&b[]=2&b[]=3
[{name:"first",value:"Rick"},
{name:"last",value:"Astley"},
{name:"job",value:"Rock Star"}]Note: Because some frameworks have limited ability to parse serialized arrays, we should exercise caution when passing an
obj argument that contains objects or arrays nested within another array.In jQuery 1.4 HTML5 input elements are serialized, as well.
We can display a query string representation of an object and a URI-decoded version of the same as follows:
var myObject = {
a: {
one: 1,
two: 2,
three: 3
},
b: [1,2,3]
};
var recursiveEncoded = $.param(myObject);
var recursiveDecoded = decodeURIComponent($.param(myObject));
alert(recursiveEncoded);
alert(recursiveDecoded);
The values of recursiveEncoded and recursiveDecoded are alerted as follows:a%5Bone%5D=1&a%5Btwo%5D=2&a%5Bthree%5D=3&b%5B%5D=1&b%5B%5D=2&b%5B%5D=3
a[one]=1&a[two]=2&a[three]=3&b[]=1&b[]=2&b[]=3
