I need to sort associative array by value (using "position" value as shown below). I tried by converting into array. It is working fine. But I wanted to know, Is there any other way of doing it?
{
"CAB":{
name:CBSSP,
position:2
},
"NSG":{
name:NNSSP,
position:3
},
"EQU":{
name:SSP,
position:1
}
}
You could also try:
Object.keys(o).map(function(key){return o[key];})
.sort(function(p, c){return p.position - c.position})
There is no associative array in JavaScript, what you have is an object, with properties CAB, NSG and EQU.
Object properties can't guarantee a set order, so the solution is to use an array of objects because arrays do indeed guarantee the order.
You can use an order array for the ordered reference to the object. You need a correction of position, because arrays are zero based.
var object = { "CAB": { name: 'CBSSP', position: 2 }, "NSG": { name: 'NNSSP', position: 3 }, "EQU": { name: 'SSP', position: 1 } },
order = [];
Object.keys(object).forEach(function (k) {
return order[object[k].position - 1] = k;
});
document.write('<pre>' + JSON.stringify(order, 0, 4) + '</pre>');
