How to create a multimap/hashtable in JQuery?

in Getting Started • 8 years ago

Hi,

I need a data structure in JQuery/Javascript that has a {key, values} pairing. I need it to be able to have multiple objects with the same key. For example, a business type key holding all google map markers created for that business type.

I would also know how to use such a data structure's get and set.

Thanks in advance.

Use a basic JavaScript object and have arrays as the property type:

var busTypes = {
retail: [
{name: 'xyz', lat: 23, lng: 123},
...
],
banking: [
...
]
};

You can add and remove items:

function addBusType(name, detail) {
var busType = busTypes[name] || [];
busType.push(detail);
busTypes[name] = busType;
}
function removeBusType(name) {
delete busTypes[name];
}
