Question

I used serialize() to get form values, for getting values back i split the serialized string, but the values are uri encoded, like ‘@’ is replaced by ‘%40’, i used decodeURIComponent() to decode, the issues looked like solved but still i am getting spaces replaced by ‘+’ sign. can use string.replace() but it would replace my legitimate ‘+’ signs in the string. How to achieve it?

Answer 1

If there are legitimate + in the string it will already be encoded as %2B. So before callling decodeURIComponent() on the string replace all the + which represent the space in the string by space and then call decodeURIComponent() to decode the string.

Use this code

var str = "%4Bseri%2Balized+String+plus"
str = str.replace(/\+/g, " ");
str = decodeURIComponent(str);
alert(str);
