remove characters in quotes after a particular character jquery

Question

I have a string like this

{'Salary':'Basic_Salary - ( ESI * .5 ) - Employee_PF + Bonus','Gross_Salary':'( Salary - Tax )','Employee_PF': ''}

If i have another string 'Salary':'',

I want to replace Salary and get the result

{'Salary':'Basic_Salary - ( ESI * .5 ) - Employee_PF + Bonus','Gross_Salary':'( Salary - Tax )','Employee_PF': ''}

I can easily check for 'Salary' . What I am stuck at is, how to replace string in '' after 'Salary':

Answer 1

You are basically working with JSON object which is coming as a string, in that case you can decode this string to JavaScript object and then modify the properties as any other object

var obj = jQuery.parseJSON({'Salary':'Basic_Salary - ( ESI * .5 ) - Employee_PF + Bonus','Gross_Salary':'( Salary - Tax )','Employee_PF': ''});

then :

obj.Salary = "Whatever you like";

then you can always convert it back to string with

JSON.stringify

Answer 2

var str = "{'Salary':'Basic_Salary - ( ESI * .5 ) - Employee_PF + Bonus','Gross_Salary':'( Salary - Tax )','Employee_PF': ''}";
var obj = JSON.parse(str);
    obj.Salary = '';
str = JSON.stringify(obj);
