JavaScript handler.get() method in JavaScript is a trap for getting a property value.
Syntax:
const p = new Proxy(target, {
get: function(target, property, receiver) {
}
});
Parameters: This method accepts three parameters as mentioned above and described below:
Return value: This method returns any value.
Below examples illustrate the handler.get() method in JavaScript:
Example 1: In this example, we will set a trap to get the value of the object using the handler.get() method in JavaScript.
javascript
const monster1 = {
string: 'Geeksforgeeks',
num: 334
};
const handler1 = {
get: function (target, prop, receiver) {
if (prop === 'string') {
return `${target.string.substr(0, 8)} ... Best portal!`;
} else {
return Reflect.get(...arguments);
}
}
};
const proxy1 = new Proxy(monster1, handler1);
console.log(proxy1.num);
console.log(proxy1.string);
console.log(proxy1.numstring);
const obj = new Proxy({}, {
get: function (target, property, receiver) {
console.log('Property : ' + property);
return 56.56;
}
});
console.log(obj.value);
Output:
334 "Geeksfor ... Best portal!" undefined "Property : value" 56.56
Example 2: In this example, we will set a trap to get the value of the object using the handler.get() method in JavaScript.
javascript
const obj = {};
Object.defineProperty(obj, 'a', {
configurable: false,
enumerable: false,
value: 10,
writable: false
});
const p = new Proxy(obj, {
get: function (target, property) {
return 10;
}
});
console.log(p.a);
let datalist = {
"vala": 32, "valb": 7
}
let get = new Proxy(
datalist, {
get: function (y, idx) {
return y[idx] * 11
}
}
)
for (let z in get) {
console.log(z + " : " + get[z])
}
Output:
10 "vala : 352" "valb : 77"
