I am using JSON.stringify
to convert object into string as follows:
JSON.stringify(obj).replace(/[{}]/g, '').slice(1, -1)
I am getting below output:
"null,null,"Heading":"Heading1""
I want to remove all occurrences of null from the above string, for which I am using replace
JSON.stringify(obj).replace(/[{}]/g, '').slice(1, -1).replace('null,', '')
But it only removes the first occurrence of null
string
"null,"Heading":"Heading1""
Desired output:
"Heading":"Heading1""
As peeps said in comments may be the best way for this is to get rid of null
element in the first place , so if you want to do that you should iterate through your object then check for null
items.
For this cause this may come handy:
Object.keys(obj).forEach((key) => (obj[key] == null) && delete obj[key]);
Otherwise, you should consider using a global flag ( /g
) in your regex, in order to remove all null
occurrence.
You can achieve this with something like this:
.replace(/null,/g, '')
The.replace() method only replaces the first occurrence. Perform global replacement as
.replace(/null,/g, '')
Hope it helps!
