Angularjs manipulate key-value objects similar to Java HashMap (landfills summary) _angularjs

Objective:

We know that the most used Java HashMap is put (...), get (...) and the Remove () method, how do you create (use) such an object in Angularjs?

Thinking Analysis:

We know that in Java you can use chained access and "[]" to access one of the values of HashMap

Specific implementation:

Chained access:

. Factory (' Paramsservices ', function () {
var params = {};
return {
get:function (key) {return
Params.key
},
put:function (Key, object) {
Params.key = object;
},
remove:function (key) {
delete params.key;}}
)

"" "Access:

. Factory (' Iparamsservices ', function () {
var map = {};
return {
get:function (key) {return
Map[key];
},
put:function (Key, object) {
Map[key] = Obje CT;
},
remove:function (key) {
delete map[key];}}
)

4. Verify

1. Write

Paramsservices.put ("ITV", "ITV");
Paramsservices.put ("ITV2", "ITV2");
Iparamsservices.put ("ITV3", "ITV3");

2. Read

Paramsservices.get ("ITV") = = Paramsservices.get ("ITV2")//True
iparamsservices.get ("itv3") = = Iparamsservices.get ("ITV4")//False

5. Summary:

Angul as a key value object (HASHMAP) recommended by the way to implement

The above is a small set to introduce the ANGULARJS operation of the key value object similar to Java HashMap (landfills summary), I hope to help you, if you have any questions welcome to my message.
