javascript - How can i make a linq

Question

 var adreees = Variables.PolicyCustomerAddresses;
 var linq= Enumerable.From(adreees)
                .Where(linq.CUSTOMER_ADRESS_ID === correspondenceAdress && linq.CUSTOMER_ID === customerCode)

adreees is an array and it is include 3 index and I want to get CUSTOMER_ADRESS_ID === correspondenceAdress && linq.CUSTOMER_ID === customerCode index's values.

Answer 1

You need to use $ as placeholder for the actual array and you need to write the condition as a string.

var adreees = [{ CUSTOMER_ADRESS_ID: 1, CUSTOMER_ID: 17, name: 'foo' }, { CUSTOMER_ADRESS_ID: 2, CUSTOMER_ID: 17, name: 'bar' }, { CUSTOMER_ADRESS_ID: 3, CUSTOMER_ID: 17, name: 'baz' }],
    correspondenceAdress = 2,
    customerCode = 17,
    result = Enumerable.From(adreees)
        .Where("$.CUSTOMER_ADRESS_ID === correspondenceAdress && $.CUSTOMER_ID === customerCode")
        .DefaultIfEmpty(null)
        .First();

console.log(result);
