Hide Null Values In Output From JSON.stringify()
In my code, all of the info from a Postgres table row are stringified when a specific rowID is selected. var jsonRes = result.message.rows; document.getElementById('panel').inne
Solution 1:
You can do something like this:
let x = {
'x1':0,
'x2':null,
'x3':"xyz",
'x4': null
}
console.log(JSON.stringify(x, (key, value) => {
if (value !== null) return value
}))

Thanks for the replies. I just realized that JSON.stringify() has a REPLACER
parameter (info here)
So I just added:
function replacer(key, value) {
// Filtering out properties
if (value === null) {
return undefined;
}
return value;
}
document.getElementById('panel').innerHTML =
'<pre>' +
JSON.stringify(jsonRes[0], replacer, "\t") +
'</pre>'
;

If you want to keep your initial object you can create a new one like this
var object = {
"ogc_fid": 143667,
"relkey": 288007,
"acct": "000487000A0010000",
"recacs": "12.5495 AC",
"shape_star": 547131.567383,
"shape_stle": 3518.469618,
"objectid": 307755,
"zone_dist": "MU-3",
"pd_num": null,
"council_da": null,
"long_zone_": "MU-3",
"globalid": "{D5B006E8-716A-421F-A78A-2D71ED1DC118}",
"ord_num": null,
"notes": null,
"res_num": null,
"effectived": 1345766400000,
"shape.star": 629707.919922,
"shape.stle": 3917.657332,
"case_numbe": null,
"common_nam": null,
"districtus": null
};
var newObj = {};
Object.keys(object).forEach(function(key) {
if (object[key] !== null)
newObj[key] = object[key];
});
console.log(newObj);
Solution 4:
Try this:
function getCleanObject(jsonObject) {
var clone = JSON.parse(JSON.stringify(jsonObject))
for(var prop in clone)
if(clone[prop] == null)
delete clone[prop];
return JSON.stringify(clone);
}
