Why this is not Working in Javascript

.......
........

key1 = 'start' + i + '';
key2 = 'end' + i + '';
datePass.push({
    key1: start,
    key2: end
});

it returns

[{key1 : `somevalu开发者_运维百科e`, key1: 'somevalue'}]

but i want

[{start1 : `somevalue`, end1: 'somevalue'}]

and so on.

How can i do so. pleas help.

try using:

datePass[key1] = 'some value';
datePass[key2] = 'some other value';

try this

var i=1;
var key1 = 'start' + i;
var key2 = 'end' + i;
var datePass = {}; // this instantiates a blank object
datePass[key1] = 'someValue'; // assigns a value to object key
datePass[key2] = 'someValue';

IF your goal is to create a list of {startx: xxx, endx: xxx} object s , since you're using push: you've to proceed in the following way.

key1 = 'start' + i;
key2 = 'end' + i;

var o = {};
o[key1] = start;
o[key2] = end;

datePuss.push(o);
