• Hemant Rajpoot: where do you want to pass?
• Rick: @HemantRajpoot I think he means parse.
• Hemant Rajpoot: did you try JSON.parse?
• Rick: @user1125829 Take a look at this

Answer 1

var jsonParsed = JSON.parse(json);

Answer 2

Below is the answer.

var resjson = respBody;
resjson.forEach(function(table) {
 var ponum = table.po_number;
});

• Himanshu sharma: either your question is wrong . I see your answer , it means how can i iterate over json object . If that is the question change it . Parse means what @minil said.
• user1125829: I had respbody json array in the question. With my answer I am able to parse the respbody json array and able to fetch fields like po_number using node js..
• Himanshu sharma: your answers shows that json is already parsed and you are just looping it to fetch index data.
• user1125829: yes. question is changed to loop instead of parse. Thanks.
